"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 had water loss in our house. In addition to the restoration work, we decided to do a broader remodel at the same time. We actually hired a different company that promised to make our house all new again, but we had a lot of delays and communication issues, and ultimately walked away from that company. We had already moved into temporary housing for the remodel, and needed another contractor to step in quickly. Johnson and Sons rose to the occasion and were able to get us back into our house quicker than the first company would have. Our remodel was basically the whole house. Floors, interior paint, all 3 bathrooms and the kitchen. The price was competitive. The timeline was good. The communication was outstanding, which was very important to us. Vic was always available to answer questions and proactive in letting us know what was going on. Jon and Tony were patient and willing to make adjustments as requested. We did discover an issue based on a previous contractor's faulty work, but Vic was quick to explain the situation and give us options and prices. We would definitely recommend them to others."

"Ryan and his crew did a great job building out Car Port. From the first time we talked to a completed project was about 6 or 7 weeks. He and his crew were very professional and, came on time, and exceeded my expectations with respect to the quality, time to finish, etc. Ryan also collaborated with another team of professionals that were contracted to place Solar Pannels onto the Car Port that was just completed. He made sure that all of their requirements and spec were addressed while building the Car Port. THANK YOU Ryan and Co!"

"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."

"Amazing experience with this company! They painted our ceilings and were Incredibly professional, flexible, and receptive to feedback. The work is high-quality, and the house looks as good as new. They left the place cleaner than it was to start with. Will definitely use them again!"

"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!"

"I hired Iconiq Construction to do my kitchen and I?m really happy how it came out. Sean and his guys were great, they told me what?s going on all the time so I never had to wonder. Everything went smooth, no waiting around, no extra money they ask for later. The kitchen looks so good now, better than I thought, and I?m glad I went with them."

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.
