"Jared and his team did an amazing job. From start to finish, it was clear they wanted to make sure we got what we wanted. Jared worked with us to come up with the design, and the team were all great to work with. They continuously kept us informed of what they were doing, and if something needed adjusting after it was done, they were very quick to make any requested changes. The job included removing a window, and re-sizing two others; replacing siding on the exterior and matching our existing paint; re-sizing the living room archway; replacing kitchen and bath flooring with tile; removing a bathtub, re-arranging the bathroom and adding a large shower; moving a tankless water heater from outside to inside; re-routing gas and water for the washer and dryer; installing new appliances; installing cabinets and quartz countertops. I highly recommend this company and will be hiring them again for future projects."

"I called Johnson & Sons for a quote on our project to build a new attached garage. Vic answered the phone himself, and while he convinced me that we are too far outside of their normal area of business to be practical, he did spend over 30 minutes answering my questions, and offering some very generous advice and references on how to approach my project. I have to say, I did not expect someone to be as forthright and open with their knowledge and ideas, especially to someone they would not be doing business with. But after reading his other reviews, I can see that this is exactly the kind of expertise and service once can depend on receiving from this highly rated company. Thank you Vic!"

"Ryan responded quickly and we were able to discuss the scope of our project. He followed up by talking to the city building department to determine what was possible and proposed a plan to get started. He also talked with us about other projects we had in mind to update our existing home. Very professional!"

"J J Construction owner Khoa Ha completely replaced my upper and lower decks with composite. He solved many problems we were facing with the decks and designed a system to deflect rain water away from the house. The upper deck was 48'x12' and the lower deck 14'x21', also replaced existing stairs, added bench seating. and lights. In addition he also repaired/reflashed metal roof on the lower back of the house and address foundation concerns. His team were great to work with, hard working, professional and courteous. We could not be happier with the results of this 4 week project. I highly recommend J J Construction for any project. We will be using him on future projects as well such as house painting, and some interior remodeling in the coming year."

"We hired Topaz Remodeling and Yoni for a home addition to create a bigger living room and extra bedroom. The project involved framing, roofing, and major structural work - and Yoni handled it like a pro. He stayed on top of scheduling, inspections, und kept us updated every step of the way. The new space blends seamlessly with our original house. We are beyond happy with the results!"

"We hired Mimos to repair extensive flood damage to our home, and while they were here, we asked them to bid on rebuilding our front porch steps which were old and rotting. They did a great job and completed the job without slowing down the other work they were doing in the home. Our steps look way better than the old ones did and it makes the house much more welcoming. They took a lot of pride in their quality of craftsmanship and materials. They arrived promptly and finished the work when they said they would. We've received a lot of complements on our new porch!"

"We were really impressed with Classic Remodeling. They did full updates on our bathroom and kitchen and we’re thrilled with the results. Their main contractor Russell is super responsive and was respectful of our budget - we never felt like they were trying to up-sell us. Both projects finished on schedule and look fantastic. We would recommend and use them again."

FAQs for addition to existing structure building service projects in Seattle, WA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
