At Jankowski Construction, Ltd., we take great pride in designing, building and preserving classic Green Lake homes!     But don't just take our word for it... read what our friends, past clients and business associates have to say:

We couldn't be happier with our new home! We have built several times before and fully understand that when you are building a home, you are entering into a year-long partnership with your builder. It is so important that this partnership be based on trust and respect. And, the relationship should also be fun. Quite honestly, we couldn't have picked a better partner than Jankowski Construction.

We thoroughly enjoyed the entire experience. When we first started talking with builders, we were impressed by Mike's knowledge, thoroughness, and ability to listen to our needs. After seeing his completed projects and talking with his past clients, we felt very confident entrusting Mike with building our home.
One of the most exciting aspects of building with Jankowski Construction was visiting the site and being able to talk with Mike and members of his crew about the progress. We truly appreciated the way we were greeted each time. Everyone on the crew treated us with respect. We truly enjoyed talking with them about the house construction. They also shared a great deal about living in the Green Lake area. We had fun interacting with them and also the subcontractors Mike brought to the job. As a result of the building process and talking with people on the job site, we feel a great connection to the community we have chosen to call home.
And last, but certainly not least, we are thrilled with the overall quality of the construction. Mike and every member of his crew and subcontractor team are truly gifted craftsmen. We appreciate everyone's attention to detail, ability to come up with workable solutions and creative suggestions. Now that our home is completed, we are so happy to join the ranks of those living In a Jankowski-built home!

Dear Mike and Julie:

I would like to take this opportunity to thank you for building our beautiful new home on Shore Drive in the Green Lake Conference Center. The house is remarkable, and we appreciate it even more every day we live there. Your workmanship is always top-notch. Mike, our experience working with you to remodel our cottage was extraordinary, but the new house has exceeded our expectations in every way.

You were a great help and resource from the siting of the property on a difficult lot to recommending elevations as well as the many cost-saving ideas to achieve the look and functionality we wanted in an economical fashion. The attention to detail on the finishing touches was really superb.

One of the things I tell people about Jankowski Construction is that you are the only general contractor I have ever worked with (Linda and I have either built or extensively remodeled several prior homes) who actually answers his phone, or in the rare instance when you don't, quickly returns any phone calls. You can't appreciate how important that is to a homeowner, especially with busy schedules and working from remote locations. It makes the process not only effective, but enjoyable.

Many thanks again for your contribution to what we hope will be our family home for many years to come. By all means, feel free to use us as a satisfied reference to anyone who is considering any job, big or small, with your quality firm.

We looked forward to building a lake home in Wisconsin once we discovered Green Lake and its beauty.   After choosing The Maplewood subdivision, we needed to find a builder.  We asked around town for a recommendation for a general contractor, and Mike Jankowski's name was consistently mentioned.  He showed us several recently completed projects which included both remodeling and new construction.  Needless to say we were very impressed with his quality craftsmanship.  In any line of work attention to detail is what gets good results, and Mike and his crew concentrated on every fine point throughout the construction process. 

We had built a home in Crown Point, Indiana about 20 years ago, and we were concerned about building a second home so far away.  Mike and his wife, Julie, made everything run smoothly.  We communicated with Mike easily via cell phone, e-mails, photos, etc.  They were extremely patient with our many questions and concerns.  Since product selection has changed over 20 years, Mike's suggestions on building materials and Julie's assistance with design and decorating guidance was most welcomed.  Without question all of Mike's subcontractors were equally experienced, extremely well versed on their product lines, and their bids were on target.  Everyone made building our lake house stress free. 

Our home was finished in December 2008, and we love it.  Having a builder from Green Lake gives us the comfort to ask Mike or Julie to stop over at the house when we are out of town to accept a deliver, unlock the house for a service man or turn off the alarm.  They have put our minds at ease that someone is watching over our home since we live hours away.  We have had many, many compliments from our extended family members, friends, neighbors and many Green Lakers.  We highly recommend Jankowski Construction and would have them build another home again.  We found them to be honest, dependable and provided quality craftsmanship.  Mike built us our lake dream home, and anyone is welcomed to view the finished product including the "fish house!"

Dear Mike,

We both hope you know what an absolute pleasure it has been to work with you on the renovation of our home. Your creativity, patience, and attention to detail brought an overwhelming project not only within reach, but made the process truly enjoyable. We can't recommend your professionalism or workmanship highly enough.

Dear Mike,

We would like to thank you for helping us achieve our new "dream" home.  We have built homes in the past and sworn that we would never put ourselves through that ordeal again.  From the first phone call to the point where we have lived in our home for almost two years, the experience has been an unqualified pleasure.

We were extremely happy with the design of the home and your creative suggestions for enhancement. 

We wanted a home uniquely suited to our lifestyle and not once did we hear the words "You (we) can't do that."  Your construction methods were concentrated on quality, longevity, and ease of maintenance with minute attention paid to detail, fit, and finish.  The job was completed on time and on budget.  Your crews worked everyday as opposed to some builders who might disappear for a few days to work on another job.  Not once did we hear offensive language on the job.  The crew members were friendly and pleasant to the point where we now consider them to be good friends.

Follow-up has been exceptional.  We were and still are always able to reach you and get prompt service and direct answers to our questions.

Without reservation, we would recommend Jankowski Construction to anyone who desires to have a true custom home built with extreme attention paid to quality and detail.

Very truly yours,

We simply can't say enough about Mike Jankowski and his team. Tearing down our old lake cottage and building a new house was a difficult decision for us. But when Mike came in with his bid on the project, he made us completely comfortable regarding the design, the process, the timing and the price. Mike is a straight shooter. We found ourselves relying heavily on his expertise regarding everything from building materials to design suggestions. We are glad we did. You just can't match his combination of integrity, talent, and experience. He delivered our beautiful new home to us on time and on budget.

Harold Mitchell was Director of Operations at the American Baptist assembly, now called the Green Lake Conference Center.  He employed Mike's team for work at the Conference Center and later for personal work on our own home on the grounds.  He would not have considered anyone else.  Mike was someone we could depend on.  He did excellent work at a fair price.  He is a man of integrity and ability.  Harold passed away in 1995, but if I were ever to need a contractor again, my only choice would be Mike and Jankowski Construction.

Mrs. Harold Mitchell
Green Lake, WI

Our first impression of Mike was right - he is a hard-working, trustworthy and more than capable contractor, worthy of the type of project we wanted to get going on.

After we bought our Green Lake homesite, we had plans drawn up for our vacation home, and Mike took our project from start to finish.  Mike and the crew were reliable and we knew they had the expertise needed to respond to our demanding set of plans.  We thoroughly appreciated his professionalism and positive attitude.  It truly was a joy to watch it happen.

Our lake home is much more than we hoped it could be!  It is a beautiful, well-crafted and fabulous destination for us, our family and friends, with lots of room to hang out and enjoy this beautiful area of Wisconsin.  We know that it is built to last.  If we had a chance to do it again, we would turn to Jankowski Construction.

Mike's ability as a contractor is evident in the quality of construction, and in the workmen who choose to stay with his crew.  It was a pleasure to work with Jankowski Construction.

Mike & Julie & Crew


Several Years ago we began a daunting project of upgrading and adding on to an old venerable lake home on Green Lake.  Our desire was to increase the living space, modernize the facilities and structure, while at the same time retaining the warmth and charm of the home.  An architect gave us an outline plan, but it wasn't until Jankowski Construction Ltd, ("Mike"), got involved that the plan became a reality.  Because of his experience, and ability to understand our desires, and translate them into concrete actions, our home, as we dreamed and imagined it, came into being.

Early on it seemed like there would be too much complexity fitting modern things and current best thought into an aged, old, stone structure, but somehow "Mike" always had an answer.  Best of all, we achieved our dream home below our cost target.  Our contract with Jankowski Construction spelled out in clear detail what we wanted and what we could expect.  Then without anguish, the specifics of our agreement were modified several times during the building process as and when unseen difficulties arose.  Never did these perturbations diminish the high degree of commitment and professionalism given us by "Mike".  In no small measure was his ability to deal with the many local subcontractors whose skill and commitment were equally essential to the success of our project.  In the end, and surprisingly unlike an earlier experience of ours, and too our great satisfaction, the product was delivered to us as promised, on time, and on cost target.

Today we consider our home a unique beauty, and while it does not compare to many of today's large expansive homes, thanks to Mike, it has a charm that brings wide-eyed compliments from just about all who come to visit.

Our satisfaction with this experience has led us over the years to call on "Mike" and Jankowski Construction Ltd, whenever a construction project arises.  As always we have walked away with complete satisfaction.  Without hesitation therefore, we wholeheartedly recommend Jankowski Construction Ltd, "Mike" to you.

I have known the Jankowski family for many years as members of the Green Lake Yacht Club and as good friends. When I started the planning for my retirement home at Green Lake, there was no doubt in my mind as to who the builder would be. It would be Mike. Although I had a plan for the house, Mike was always there to make suggestions and adjustments that would make the house better. As the house was being built, Mike and Julie stayed in constant contact letting me know what choices (carpeting, tile, light fixtures, etc) I had to make and where to shop. Each week I came to Green Lake to view how the house was coming along. Mike took time to meet with me and explain what was being done and what would come next. When the house was finally finished, Mike and his crew helped me move things that had been stored in one of his storage units and set everything up for me.

I truly love the house. As a testimony to Mike's skill and professionalism there have been no problems with the house. In fact people who have visited me comment on what a wonderful job he did. I would certainly recommend Mike as a builder. He is knowledgable, skilled and honest.

I am one of many people in the Green Lake area that have enjoyed a terrific working experience with Mike Jankowski and his team.  Mike takes a "hands on" approach to his work and it is valuable to have someone with his experience working day to day with the team.  I also found Mike to be very creative when the situation required the proper cost/benefit comparison.  Mike has a solid reputation from many years of leading a very high quality construction business.

Over the years, I have referred a number of my friends to Mike Jankowski and his team.  All of us have benefited from the straightforward and honest approach Mike takes to his business.  It has been rewarding to know a person that puts so much pride into their customer experience.

A Perfect '10'

As I was growing up, I remember my father would always pay careful attention to professionals who took pride in their work.  He would say that it was always better to wait a little longer or pay a little more and work with people who would do the job right.

From my own experience, I can say that it has become increasingly more difficult to locate those few people who still want to do the job right.  All too often we are vulnerable to working with the new generation of trades people who seem to be motivated by money.  For everyone who shares my frustration, I have some great news for you.

Among many fine things I have discovered about Green Lake, one is the quality and character of the people.  Furthermore, I have found true professionals who really do take pride in their work.  They are Mike Jankowski, Mike Brooks, Rod McDonald, Kea Krueger, Murray Sandleback, Dan Braaksma and Steve Stahl.  The next time you find yourself comparing the merits of one contractor versus another, I urge you to consider pride as an important criteria.  In this category, each of these professionals scores a perfect 10.

The Jankowski Construction team is who you would want to build your dream home in the Green Lake area.  Their craftsmanship and attention to detail is something you rarely find these days.  They stand behind their work and are extremely talented.  We wish they could have built our home in Chicago.

During the past twenty two years Mike has served us well, always with a cheerful personal interest and in a professional manner.  In "finishing" our basement and adding an addition to our home, his choices of design and materials, as well as workmanship, have been excellent.  Other projects Mike has done for use, likewise, have won the test of time and beauty.

We strongly recommend Mike Jankowski, really a "nice guy", as your builder.  He remains ours.

Dear Mr. Jankowski,

I would like to thank you for helping me with the planning of my Eagle Scout Project.  Without your help I would have had a very difficult time designing my information board.  I have completed the building part of my project and have moved on to the paper work.  If you would like to see the completed sign it is located in the parking lot of the Town of Ripon town hall on Douglas Street.  Thank you again for your time and help, it is much appreciated.

When Sunset Point Condominiums were completed in 1995 we were already looking forward to future projects with Mike Jankowski.  Our condos were done on time, on budget and the craftsmanship was excellent.  Each time we drive by, we look with pride at what Mike and his team accomplished.  A job well done!

Mike Jankowski built our original home in Green Lake in 1989.  Since that time Mike and his crew have done every major and minor improvement to the home.  Major jobs include enclosing a deck that ran across the back of the home on the lake side.  It turned out absolutely beautiful.  You would never know that it was an addition.  Most recently Mike and his crew added a deck to the added room.  His design and execution is of the highest standard of excellence.  His attention to detail is outstanding.

Over the years many friends have visited us as you might expect with our being on the lake.  We have always been delighted with their gracious comments regarding the beauty of the home.

You can only remodel an old lake cottage so many times before it becomes like Forrest Gump's chocolates - you never know what you're gonna get.  SO we were apprehensive when our daughter turned eight and realized her room was too small and too dark for her and her doll Kirsten.  She determined life would be delightful with a sunny window seat where she could snuggle up with a book, her cat and Kirsten.  Thank you, Mike, for making it happen.  Cantilevering the dormer off the Mansard roof was an engineering masterpiece.  After eighteen years, everything remains rock solid.  Our daughter still lounges in the warmth of the sunny window seat, but now with a cell phone, a new cat and a stuffed orangutan.

We chose Mike on the recommendation of his Green Lake High School math and science teacher, who happened to be a master carpenter in her spare time, herself; she told us that Mike was a really smart guy.  We were also impressed by homes he had built in both the Green Lake and Princeton areas; each home was highly individualistic and showed fine craftsmanship throughout.  Mike went out of his way to make our home affordable, without sacrificing the spacious country feel we wanted.  For just one example, he found us rustic pre-finished rough-sawn wood siding that has not needed painting in the 22 years we have lived here.  His employees -- two of whom have been with him since before our home, which shows their loyalty - showed equal attention to detail and general helpfulness.  One built custom cabinets and a two story loft bookshelf, with an attached ladder, from pictures we had clipped from a magazine.  Another showed me how to lay the oak floor in our Great Room and Kitchen (Mike let us do some of the work!).  Overall, although building a house is supposed to be a really stressful event for young couples, Mike's intelligence and empathy made the experience one of our favorite memories, and we expect to live in the beautiful house he built for us forever!

For over 35 years Mike and Julie Jankowski have run a construction business that has produced outstanding results for their customers in the Green Lake area.   In our personal experience, Mike Jankowski, Julie Jankowski, and their very talented crew remodeled our 50s ranch house on Green Lake to add a second story and beautiful pitched-roof living room to meet the needs of our expanding family.    Everyone who has looked at the results has been blown away by the quality and attention to detail that was the result.

In addition, since we were living in the home during the major remodeling, we we able to see first hand Mike's consistent willingness to make adjustments throughout the project.   His crew's consideration of our family's needs was much appreciated.

Jankowski Construction's local knowledge of artisans who can add value to the project cannot be duplicated.

We believe that anyone with a building project in the Green Lake area would be making a BIG mistake by not hiring Jankowski Construction, Ltd. with its talented team.


Peter and Jocelyn Hoeper

At the time of our request for contracting services..we were involved with considerable travel in our own business.   ..and therefore not present for any plans or details as it related to our desired project.  Our only basic request was to build a garage..40x50 with sleeping quarters.   We did specify complete insulation and finished walls..and "no maintenance" outer panelling.  What we got can only be described as..you've heard of the "Taj Mahal".. Mike/Julie, & crew delivered what we call the "Garage-Mahal".   Our neighbors and friends who see this structure all marvel at the detail.   The quality of workmanship in the windows was specially outstanding..after all, this was just a garage, and exceeds what we have in our homes in Florida and Green Lake!

Finally, after a couple years, we still marvel at the apparent creative ingenuity on the part of Mike and his crew to design the layout with window positions and appropriate drainage..all without our input..since we have no building or construction knowledge.    So should we require more contracting, I would have every confidence in consulting  Mike, Julie, and their crew to get the job done in a timely and efficient manner.

Eleven years ago Mike did a remodel on our newly purchased lake home.   Mike helped us develop a sound plan, he had numerous ideas and suggestions.  Today everything remains in good condition.

Dr. K. W. Piernot

After purchasing a lot in Green Lake my primary concern about building from a distance was, who can I trust to build what I want without being there every day to inspect the results.   I had heard of Mike and Julie Jankowski thru friends and was able to see several projects they had done.

The house plan I wanted to build was not quite right for the lot.   Thanks to Julie she found a similar plan that worked perfectly.

Any time I had a question for Mike in the building process he was prompt in returning my calls.

I felt well guided thru each phase of construction.   Mike and Julie use a very "hands-on" approach.

When I had to change my move-in date up by two months, due to a quick sale of my out of state property, Mike and Julie were more than ready to make it work.

Compared to my past experience of new home building this was much more personal and enjoyable with a true concern for attention-to-detail.

Many people have commented, "What a beautiful home!".

Thank you,

S. A. Shook

It was time to fulfill our dream of building a year round home on the grounds of the Green Lake Conference Center.

Mike met with us in the winter months, guided our plans and visited other homes with us to explore ideas. One we especially valued was his suggestion to use a south facing clearstory on our house in the woods. It has a year round benefit.

Due to a prior commitment, Mike could not build the house by the time we finished our plan.

A few years later it was time to finish our walk-out level. Mike did a wonderful job of advising on the layout of bunk room, TV family room, storage-work room, and utility-laundry room, then making it happen. We've spent many enjoyable hours in these functional, well finished rooms.

This was a complete interior remodel due to severe water damage.

Dear Mike:

Over the Thanksgiving holidays I had occasion to spend some time at Green Lake. You did a great job with everything in the house. The interior is bright and comfy, the basement excellent and the windows and doors look great.

I am grateful to you for having taking on the job and I knew if you did it, all would be well. Thanks so much!
