"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 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 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."

"C&S repaired an in the wall leak - including drywall, siding, plastering and removal/restoring frame for a sliding door. Because they were so easy to work with, I also had them replace my rug and kitchen flooring. I really appreciated the excellent work C&S provided, beginning with the estimate to quality workmanship completed in a timely manner. Sandra responded quickly to any questions I had with easy-to-understand answers and options. Cesar listened to all my input and communicated to his crew so that my needs were quickly implemented. I highly recommend using this company. They will be the first ones I call to bid on any future home projects."

"I highly recommend Yariel Bello. He is communicative, does quality work and is a flexible problem solver. I wanted a fence that wasn’t too expensive, but still had curb appeal so I went for a hybrid wood/chain link look. Yariel knows just the right balance of making little decisions on his own/calling me for clarification when needed. Yariels pricing is very transparent and he also graciously came up with an economic solution for building a fence around a tree on the property line"

"We found that the wall in our laundry closet was soft and damp. After opening the wall a bit we found massive water damage. Ray with Lopez Bros Construction responded quickly to our request for quote, came out and assessed the damage, and gave us an idea of what it would cost. He then pointed out the demo work that was needed and offered to allow us to do what we could of the work to save us money. Once the demo work we could do ourselves was done, Ray and his crew came out to complete it and then identify where the leak was. This had clearly been going on for some time as the entire floor and subfloor was completely rotten. Ray coordinated the plumber to fix the leak, remove the water heater that was in the garage on the other side of the laundry wall as it was pressing through the other side. After allowing several days for everything to dry out, Ray and his crew then began building back the floor and the walls. Work was completed within a week. Everyone was professional and careful to keep the mess to a very minimum. Ray communicated everything he found, his plan to fix, and showing progress throughout the project. He always let us decide how far to go (removing the water heater and repairing the other side of the wall was our decision) and never pressed to do any more than what we were comfortable with. The project was much bigger than expected, but the price of the work wasn't much more than what was originally discussed. SUPER happy with Lopez Bros work!"

FAQs for addition to existing structure building service projects in Renton, 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.
