We recently did a bathroom project in which we completely remodeled 3 of our bathrooms. Carlsen Design & Construction proved to be a great choice for this project. Greg was consistently professional and patient with us as our vision for the project constantly evolved; when we had new ideas, he would promptly accommodate our requests.

We hired Greg's firm to do some structural work on our Victorian row house before selling. Greg and his team did a superior job. They were timely and efficient, they met our tight timeline, and the quality of the work was noted by the home inspector. Once they finished, we couldn't even tell that work had been performed.

I used Carlsen Design & Construction to create a new window in the wall of my kitchen. While the project sounds easy, it was actually quite complicated because I live on the fourth floor of a condo building in the Cleveland Park section of Washington, DC.
