Excel General Contractor is a full service home remodeling and construction contractor. We offer a high level of customer service while maintaining fair pricing. Our team is small enough that you get individualized attention but big enough to get your project done effectively and efficiently. We do all projects from small repairs and renovations up to designing and building you a complete new custom home.

"Nate allowed me to order my bathtub myself, which was nice. Lowe's failing to deliver when promised, was not. This delayed the start, and although it did take longer than I expected, everything came out great. They did not charge me extra after the water damage was exposed, which was a relief. One of the other estimates I got from a general contractor was for 3x as much, AND they planned to add on after the wall was opened. The bathroom specialists wanted 150% of what we paid, and I think we ended up with better results."

As a family-owned business, we pride ourselves on bringing a personal touch to every project, ensuring that each home we work on resonates with the dreams and aspirations of its owner. Our specialties encompass state-of-the-art kitchen redesigns, midsize to major home overhauls, and cutting-edge Detached Accessory Dwelling Units (DADUs). Our tech-savvy approach ensures that our projects not only meet but exceed the expectations of today's tech-oriented homeowners. With full licensing and bonding, we guarantee that no project is too ambitious for our seasoned team. Trust in Wylie Construction to bring your tech-integrated dream home to life.

"We hired WPC to construct an addition our home. The project started well and we were generally happy with their work. There were several points where their oversight of subcontractor work was lacking, including a major framing mistake and roofing material that did match the rest of our house. Their invoices lacked details and upon requesting receipts and hours breakdown it was clear there were some discrepancies. For example, we were charged 8 hours for two 20 minute inspection appointments. Getting towards the end of the project it was clear that they were going to far exceed the budget our contract specified and work was very sporadic, dragging the project schedule out unnecessarily. We had a disagreement about how they were applying their margin to a new heating system in our existing home (i.e. not part of the addition), which eventually led them pulling out of the project. Had they not done that, we would have fired them due to their poor performance. We had a neighbor who hired them for a DADU project and he had a similar complaint about them not being able to deliver at the end of the project. We were lucky to find another contractor that actually showed up to do the work and did exactly what they said they would do."

"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"

The kitchen turned out exactly how we wanted it, and we are so happy with the quality of the work."

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.
