"We hired Topline Builders and Renovations for a full home addition, adding nearly 600 square feet to our main floor. From the very first consultation, Ben walked us through the architectural plans, structural requirements, and permitting process with the city. We were nervous about taking on such a large construction project, but they made it feel organized and manageable. The framing crew worked efficiently, inspections passed without delays, and the final finishes blended seamlessly with the existing structure. You honestly can?t tell where the old house ends and the addition begins. Communication was consistent throughout the entire process. This wasn?t just a contractor showing up ? this felt like a professional construction team managing every detail properly."

"We hired Vic and his team to replace a gas range with electric. This task was complicated by the need to upgrade our electrical panel and run new cables to support the new range. We also needed to cap off the old gas line and repair and paint drywall. They made sure that everything was up to code (including correcting an existing problem they found with grounding) pulled the required permit and arranged for inspection of the completed work. We were impressed by their professionalism throughout. As well as doing quality work they also were very careful to protect our home and clean up once complete. We were very pleased with the finished job and would definitely hire them again."

"Ryan from Johnson Custom Builders was referred to us from our neighbors. He is a design builder. After seeing his work there, we hired him to build our custom deck and prepare it for a deck cover installation. He took the time to learn about our project idea and offered options to build it. All throughout the project he made sure that we are informed so we can make the decision that best suited our project needs and budget. He took our project to design, architectural and engineering phase then permitted the project and built based on the approved architectural plan. He is very open and clear communicator and very patiently answered all our questions and helped brainstorm ideas. He was the liaison with the company who is building the deck cover and his expertise and attention to details was key for us to choose the right cover product and design. Ryan and his crew are very friendly and respectful. Their work is outstanding. We are very happy with the end result and will call them again for future projects."

"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!"

"After experiencing water damage to my kitchen/dining room, I sought a contractor to do drywall, flooring & painting. In addition, to construct a new pantry door, and change out my remaining, first floor hardwoods for porcelain tile. I immediately felt a "good vibe" from Yariel from Bello Home Solutions. He was organized/systematic, detail oriented, very "engaged" with my project needs and personable. He and the Bello Home solutions team were expeditious and did high quality work. Yariel had great suggestions, and was easily reached when I had questions. I felt very comfortable giving the Bello team access to my home when I was away. Bello Home solutions did a fantastic job and I am already mentally planning my next home construction project with them."

"Kevin did an amazing job, responded right away & accommodated my schedule.He built a wall, creating an office space.He made sure I am aware of all the steps & took pics of the frame and insulation before drywall was installed. He moved the thermostat and installed 2 outlets on the new wall. He painted the new room, living room, hallways and 1 bedroom. The paint underneath was dark blue, so he made sure to apply enough coats to cover it perfectly. He removed an iron chimney and covered the ceiling, also bringing the floor under the chimney to the same level as the rest of the living room and covered with hardwood. He installed a fan on my vaulted ceiling in an angle and a new light in the office space and left the house clean of all debris. I am beyond impressed by the quality of work and professionalism he showed from start to finish and I will definitely hire him again.He is reliable, accommodating, respectful & hard working.Hire Kevin without a doubt.You won't regret it."

"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.
