Expert Sunroom Construction in Seattle, WA

Seattle gets more than 150 rainy days a year, and that makes a well-built sunroom one of the most practical additions a homeowner can make. Framework Construction handles sunroom construction from structural planning through finish work, treating each project as a true home addition rather than a bolt-on enclosure. Our co-owners bring over 40 years of combined residential construction experience across structural framing, windows and doors, roofing, and finish carpentry. That range matters on a sunroom build, where the structure, glazing, roofline, and interior details all have to work together. We serve homeowners across Seattle, Bellevue, Sammamish, Mercer Island, Kirkland, Redmond, Issaquah, Woodinville, Bainbridge Island, Clyde Hill, Bothell, Kenmore, Gig Harbor, Maple Valley, Fox Island, and Poulsbo. Every project gets personal attention from ownership, careful planning, and the kind of detail-oriented execution that makes the finished space look and perform the way it should. If you are ready to add a sunroom to your home, contact Framework Construction to get started.

Denis showed up on time and did exactly what he quoted. Fixed my back patio cover, removed damaged boards, and reattached my gutters. He is very experienced, friendly and efficient. Definitely would recommend and I will use him again.

Denis and his father are a great team! So professional and communicative. We were looking for someone to construct a 2x 2 post pergola for our patio and that is not easy to find! Denis was on top of it, asked great detailed questions to ensure we were going to be happy with the work. They built it from a diagram, installed and secured it to our patio in one day and It looks great!! We fully recommend them!
