★★★★★ Bill Bertsch’s company replaced our roof and did an excellent job from start to finish. They worked fast, at the onset of winter, and got the roof on in a couple of days. Nice people, good at answering our questions, and responsive when we had a few other minor things that needed doing. Highly recommended.

★★★★★ Bill and his team did a phenomenal job both painting the exterior of our house and building a new deck twice the size of the one we had. Bill was very responsive when we were getting quotes even while the building market was insane due to covid, and there were building supply shortages. He and his team were always on time, extremely professional, well-prepared, very skilled and left their surroundings exactly, if not better, than they found it. Very pleased with their work, and would use them again. Highly recommend.

★★★★★  Bill did some renovations on the exterior and interior of our home and we are so pleased with the results. He did everything that we had discussed and left our home perfectly clean when he was finished. He communicated very well with us during the process. His prices are fair and is work is excellent. Truly a pleasure to work with!

★★★★★ I engaged Bill Bertsch Construction to insulate the crawlspace of our newly purchased lake home and re-roof our garage. I was very impressed by Bill’s work; it was completed quickly, no surprises, and the workmanship was excellent. With the successful outcome of those projects I knew I could trust Bill and his team to renovate a bedroom and build a new bathroom. As an engineer, my first concern is attention to detail – particularly when something comes up in the construction process that is unexpected and has potential life safety issues; we found out that the roof on the room being renovated was comprised. Bill informed me of the issues, provided options, and discussed the pros and cons of each. Bill resolved the issues quickly and performed all of the tasks that you would hope you could take for granted – replaced bad wood, installed new insulation, and mitigated the flashing issue that caused the problem in the first place. Bill also identified potential carbon monoxide concerns and mitigated those as well. He and his team finished out the project on time and on budget. His workmanship was outstanding. As someone who builds cabinets and works on full scale aircraft periodically on the side, I know good workmanship when I see it. My wife and I are planning more projects in the future and now, with this experience behind us, one problem we don’t have to worry about again is who is going to do the work and do they care about the work they do on our home. Bill Bertsch is my choice – period – full stop.

★★★★★  We had the pleasure of having Bill and his team build our 14′ x 14′ deck. Bill was professional from the start, from his design to the detailed finished product. Timely, courteous and precise. The work space was always clean and tidy. Skilled workmanship was done with precision and care. Would highly recommend Bill and look forward to hiring him for future projects.

★★★★★  Bill is the most reliable contractor you will find in the area. He did work on two of my homes and the construction was solid. Much better than the contractor who built the structures he added on to. Bill will show up when he says he will (great communication!) and….. he shows up to give you an estimate! He leaves the site clear of construction debris when he is finished and did a great job preserving surrounding landscape and structures. I have referred many people to Bill over the years and continue to as I have such confidence in his work.

I cannot say enough good things about Bill and his crew. They just finished a very large project which included a complete new roof and some major repairs from the March storms. They were punctual, let us know each step of the way what was being done, and what rooms they would need access to. They cleaned up everything, no mess left behind. The workers were very polite and professional. This company is top rated. If we need more work done, Bill will be the one we will call.

★★★★★  I don’t normally do reviews, I probably haven’t written four in as many decades! However, I couldn’t let our experience with the Bill Bertsch Construction Company go by without comment. We needed a new roof; it is a large roof with a complex configuration. An already difficult job was made harder by the fact that the roof and crawl space needed significant structural repair work. The work was done in May of this year. If you’re familiar with the Hemlock Farms area you know that that was a very rainy time. Any day it rains, no roofing gets done! When the weather permitted them to work the workers worked like the Hammers of Hell! They worked continuously, at a steady pace with no downtime as long as rain wasn’t falling. They are now finished! The quality of the work done was superb, the amount of work done every day was exceptional; the site was picked-up and cleaned every day. The workers never stopped except for lunch time – if they were on the site they were working! Bill Bertsch was very clear in explaining, to us, the work to be done, how it was to be done and he warned when the near-term weather would interfere with the pace of work. He is an excellent communicator – there are no mysteries and he is very flexible and accommodating. The job was done as explained, on-time and on-budget. I now have a contractor for life! H.

Bill, Once again a sincere thank you for all the work you did at our house. Mary and I are very fortunate to have found your company as our contractors. I hear nothing but horror stories from my friends about work they have done but I have no stories like that to share! I only have the highest praise for your professionalism and quality of work. It is especially important to have someone dependable when the customer is not around to observe what is going on. (I know you are happy I was in Port Washington) so although I have said it many time before I say it again for Mary and me. Thank you, thank you for all your efforts in making our home a beautiful place to live. Please accept this check as a small token of our deepest appreciation.
