I have know Carl from Thomsen Construction for over 5 years now. I have seen & done much work with the company. Everyone, from the direct contracting team, to the office manager, & of course the owner himself, is absolutely professional in the highest level. They have worked on major projects all over this state. Their work crew has a great eye for quality & know how. They are clean, neat, & know how to finish. Simply put, this outfit is the real deal, & if your given a chance to have them work for you, then you are gifted home owner.
As a subcontractor for Thomsen Construction I cannot say enough good things. Carl and his crews are courteous, thoughtful, understanding people who are a pleasure to work with. Their projects are first rate quality and absolutely gorgeous. I would highly recommend them to anyone looking to build or remodel their home.
Carl and his company are exceptional. His workers are always on time. The carpenters work quickly and accurately and the finished product is always perfect. They clean up after themselves each evening which is always a good sign. My last project was to install an interior door, install an access hatch to under my deck and make exterior repairs before the winter. As always, I was extremely satisfied.
My husband and I recently hired Thomsen Construction for replacement of our exterior siding and shutters, and skylight, and other carpentry needs. The work was on time and completed with great care and obvious expertise. Loren French, the project manager, sent regular updates by email, calls, and visits. We were amazed at the attention to detail throughout. Many thanks for a fairly stress free renovation experience!
A pleasure to work with and a job well done! Work was done in a timely manner with little interference into our daily lives. You can't ask for more than that.
