Dear Jon and Christine, Thank you so much for building the house of our dreams! Being in real estate for nearly 30 years, we have had lots of experience with various builders. We are well educated buyers and are aware that making the wrong choice can be disastrous. From the moment we met with you, we felt comfortable and knew we were making the right choice. Now that the home is complete we understand your slogan, “A builder you can trust”. We thoroughly enjoyed and trusted each and every person that worked on our home and their attention to detail. We felt like you and your crews were like family and truly cared about the end product. The level of finish far exceeded our expectation. Knowing that you were both HANDS ON every step of the way made us feel that you truly had our best interests at heart. A truly positive experience from start to finish!! From our family to yours, thanks for a job well done!!!

When I decided the timing was right to build a new home, I wanted to work with a builder I could trust, respect, and who would listen to my dreams and have the skill to make them become my reality at a reasonable price. I have no regrets and am grateful to have had J Timothy Builders as my builder.

From the beginning, I knew that Jon and Christine Wittrock were exactly the kind of people I wanted to partner with. Building a new home is an enormous project. Jon and Chris simplified the process and I was in the loop at all times. We really were a team and only wanted what was best for the house. Their subcontractors also were top rate people, and offered their creative input too, which was great. It wasn't just a job for them either.

Working with J Timothy Builders, you will be pleasantly surprised by their attention to detail, craftsmanship second to none, and honest old school integrity. I would highly recommend J Timothy Builders to anyone who wants their dream home to be built on time, and for the dollar amount agreed to in the beginning. They will embrace the project as if it were their own.

My new home built by J Timothy Builders went way beyond my expectations. Everything they said and predicted came true.

 “A Builder You Can Trust” is the slogan for J. Timothy Builders.  We wholeheartedly agree!  The owner, Jon Wittrock, is well versed in the technical aspects of building, as well as hands on, in the structure that became the product of our dreams.  Jon is on site giving practical suggestions along the way, conveys them with clear understanding, and keeps the budget in mind.  Another valuable asset is his ability to select skilled crews who are professional and produce quality work.  Jon is a master of patience and has a wonderful sense of humor.  Thanks to the vision of their lead carpenter, Beau, we were able to make valuable revisions to enhance the looks and functionality of our home.  As complex as building a house can be, we would look forward to doing it again with Jon in charge.  We highly recommend him to anyone who wants to be thoroughly in love with their home at the end of the process.  It was reassuring to be able to simply say, “Jon, we are sure you will do it right…we trust you!”

Karen and I would like to sincerely thank you for the dedication, commitment, and quality workmanship that you provided in completing our project in Williams Bay.  Working with you both was an absolute delight. 

Jon, your commitment to staying on task and on goal showed through in every situation we uncovered.  We realize that this may have been one of the more difficult projects you have completed.  While building a home on the side of a hill is no easy task, you continuously plowed on with a great attitude and a vision for the completed project.  We were very happy with the way your crews and subs tried to work with us and guide us to what we believe is a simply outstanding home.  In addition to that you should be very proud of the relationships you have established with them.

Every single one of the people we worked with had the highest regard for you as a boss and friend.

Christine, thank you so much for keeping us on task.  Your record keeping and approval process is the most detailed and complete project management process I have encountered on any project.  Your helpful nudges kept Karen and I moving and always helped us stay ahead of the next decision.

We are delighted by, and proud of, the relationship we have established with J. Timothy Builders and would welcome the opportunity to provide any references you may request.

Thanks again and especially thanks for treating our project like you were building it for your own family!

My wife and I visited several homes built by J. Timothy Builders prior to meeting Jon and Christine.  We were impressed with the quality of their work, and hoped they could match our vision for our new home.  During the meeting, Jon and Christine’s hands-on approach, integrity, experience, creativity, and sincerity became obvious and we quickly hired them.  Not only did they understand our vision, they improved upon it.

As an architect, I was very particular about all aspects of the work, from the design through budgeting and construction.  They stayed on course, understood our priorities, and always offered insightful, creative solutions.  Their team of trades and consultants were professional and each offered an added level of problem solving.  Jon coordinated his team well and constantly updated me on the progress.

Now that the home is complete, we are THRILLED with the results!  So thrilled that we plan to live here for a long time, but if we ever choose to build again, we will start by hiring Jon and Christine.

We watched with delight the transformation of our single family to a multigenerational home, under the direction of Jon, Christine and team!   Jon and Christine were wonderful to work with and made the overall process easier than we could have hoped.  Our goal was to have a home that accommodated all our family as well as be energy efficient and we achieved both.  Today, not only do we have a gorgeous new home, but one that showcases a multitude of renewable, sustainable energy efficient technologies.

Thank you Jon and Christine!

The decision to hire J. Timothy Builders, Inc. to build our home in Geneva National was a good one.  One of the nice things about working with Jon and Christine is having single source responsibility.  The home’s custom design and construction come from the same company. 

Jon’s sense of design, knowledge of the construction process, hands-on carpentry skills, and overall attention to detail is truly impressive.  Plus, he is physically on the construction site every day making sure things are done right. 

Along with a great eye for decorating, Christine has the “behind the scenes” office and organizational skills to keep the project on schedule and running smoothly.  They were both also very good about taking our design ideas and making them better.

Thank you from the bottom of my heart!
