"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!"

"I am a repeat customer, so I knew the carpenter, Joe, coming in. I started by using their design contractor. I gave her the colors and ideas (beach theme, ceramic wood-look floor tiles), and she pulled the rest together. Invaluable because I can't trust my own taste. They removed a square shower in the corner and a set of shelves next to it, and glassed in that end of the room for a full shower. We put tile down along the whole room, with a recessed shower pan, and a linear drain against the wall. Joe built-in medicine cabinets, and trim all around the room, per my design pictures. The subs included a glass door guy, the plumber, the tiler, painter, and the countertop slab tiler. We also had some work done in our hallway. They removed the single boob light from the middle, and installed two recessed lights on either end, along with putting two switch boxes on either end of the hallway. Joe built a floor to ceiling cabinet in a 13” dead space at the end of the hallway, which included a laundry hamper on tracks, cubbies, and shelves. And then on a whim, I asked to have our old hallway linen cupboard doors replaced to match the new ones. We had two leaks during and after, but one reason I would use them again, is how they handled both times. One was a leak from the plug on the toilet supply. We found it on a Saturday morning, and I ended up waking up our carpenter with my text. He came out and figured it out and fixed it by 1. The other one was after everything was done and cleaned up, and we had paid for everything. The basement bathroom ceiling, fan, and wall below the master was wet one day, and we realized a joint in the pipe from the master toilet to the stack was slowly dripping between the two rooms. I texted Joe again, and he referred me to our GC, who came out with a plumber and fixed it. They had to make a hole in the downstairs drywall, so he has been coming back regularly to put three layers of mud on the new drywall. I was so sure that they would regretfully find that it wasn't their fault and we would have to deal with the cost and bother of finding a plumber and carpenter. Start to finish, it took about four months, but three weeks of that was the initial tile order, and another three for an incorrect tile order."

"I cannot say enough good things about Vic and would highly recommend him to anyone I know. We stumbled across him on Angie's List as we needed help installing an egress window prior to the sale of our house. I'm so thankful we found him! We also had him take care of a few other projects like building a stair railing and addressing a plumbing issue. He did a great job on all of the projects we hired him for. He is hard working, dedicated and definitely knows what he is doing. His pricing was very reasonable and I felt like he really cared about taking care of his customers. All of those traits are not easy to find. I've been through a lot of contractors and he is definitely my favorite. I would hire him again in an instant."

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.
