"We worked with Renovate from August 2024 through April 2025. Our experience was exceptional. Ross, Eric, and Jeremiah were efficient and effective, treating our project with great care. The Renovate team stands out in several ways: - Their pricing is transparent. We paid an hourly cost and subcontractor costs, plus a fixed mark-up, which aligned incentives. Amanda provided receipts and timesheets regularly. - They have superb attention to detail. They pointed out issues we might have missed and ensured they were fixed. - They were super responsive, encouraging us to text or email any time and often responding quickly. They kept us updated on the timeline and explained any delays. - They have a strong client focus. They addressed subcontractor errors quickly and reminded us to ask for what we wanted, even if non-standard. They provided recommendations but let us make the final decisions. We highly recommend the Renovate team. For our more detailed review, see Google."

" We engaged My Baker after our basement flooded a few years ago. They did very good work on a project despite it being during the pandemic. Their workers were respectful and the project was finished on budget at quality standards we were thrilled with. "

"Anyvision and Chase were excellent! Their bid was competitive, and their contract was clear and straightforward. What began as a simple shower pan repair turned into a full master bath remodel and a new roof due to water damage. Having dealt with poor contractors for 45 years, we feared the worst, but Chase handled everything seamlessly. He assessed the damage, adjusted the plan, and had the skilled crew to execute both repairs and high-quality finishes. The team was punctual, professional, and kept our home clean. Chase’s tile specialists did exceptional work—no metal edges, just beautifully mitered finishes. With the remodel being unexpected, we had to make quick decisions, but Anyvision’s designer and CAD renderings helped us visualize everything. Chase was onsite daily, keeping us informed with updates, photos, and videos. Challenges arose, but Chase managed them like a pro—offering smart design input, controlling costs, and maintaining quality. This was the best contractor experience we’ve had in the PNW. Anyvision is the real deal, and we’d hire them again in a heartbeat. Their communication, expertise, and customer-first approach set them apart"

"We had a great experience working with NRC Homes on a significant remodel as we prepared to move into our new home. They were highly organized, very communicative, and a pleasure to work with. Despite a tight timeline and several changes along the way (Due to changes from us), they delivered everything on time and were incredibly patient and flexible. We’re so grateful for their professionalism and would absolutely recommend them!"

"Pacific Pro Group did a great job on our kitchen remodel. The final result turned out exactly how we hoped. Communication was solid throughout the project, with regular updates through Buildertrend so we always knew what was happening. The design team did an excellent job laying everything out and providing a clear spec sheet that made the process straightforward. Highly recommend Pacific Pro Group"

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.
