"Bryant and Skookum were outstanding to work with. We used them to repair siding that had water damage and to replace our front door. Their work was high quality and their customer service was great. Easy to reach and questions answered quickly. Price was very reasonable too. Will hire them again when we need home repairs."

"Emrah, with B&E Construction was very prompt, courteous, and professional. He and his team removed old ceiling popcorn from a family room, and connecting bedroom. This was from an older home built in 1979. The popcorn was extra dense and thick which made removing it more prolonged and tedious. Emrah and his team did phenomenal work, and we are very grateful for them!"

"Seemed ok at first but then chose to come talk to my husband when he thought I could not make it to appointment. After over 6 months the project never got started. I had funding in 2 weeks so that was not the problem. Might do a good job if he ever gets started, but only if he's dealing with men. I'll never know. We gave up and moved on. I need my project done, not just talked about."

Addition to existing structure building services FAQs

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
