"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!"

"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."

"Johnson Custom Builders performed the initial design work on a home addition to add a “Mother in Law” apartment. My only stipulations were it must have: separate entrance, separate kitchen and separate bathroom. The lot size presented problems and access issues. JCB presented a solution that took into consideration that only his experience could foresee: building codes, drainage and aesthetics."

"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."

"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."

" recently hired Northwest Builders & Renovation to build my garage, and I couldn?t be happier with the results. From start to finish, their team was professional, responsive, and detail-oriented. The communication was clear every step of the way, and they delivered exactly what they promised ? on time and within budget. The quality of the framing, concrete, and finish work exceeded my expectations. They took care of everything efficiently, handled permits smoothly, and left the site clean every day. It?s rare to find contractors this reliable and dedicated to doing the job right. I highly recommend Northwest Builders & Renovation to anyone looking for skilled, honest professionals who truly care about their work."

"I interviewed several contractors for my addition and addition and I chose Andrew because I felt like he was straightforward with the project and the risks that come with a remodel of an 80 year old house along with the primary suite addition. Through the design phase, we never felt pressured to make decisions, but were kept informed of the timing of the project and when we needed to make decisions in order to schedule the project in a way that minimized the impact to our family. Andrew walked us through each item in the contract and worked with us to make changes to fit our budget and kept us informed on what we could expect for changes for a project like ours. Once we were out on contract, Andrew helped push permits through county and kept us informed on what we could expect for duration and timing of the project. Once the work began, Andrew and his right hand man Rod worked efficiently and coordinated the project beautifully to minimize the amount of time that we were displaced from our home. Thoughtful suggestions were made to deal with the numerous issues that come with renovating an 80 year old house and Andrew supported my questions on cost impact and the criticality of each change to keep me informed so that we could make decisions that we felt comfortable with. Andrew and his team of subcontractors were all very friendly and respectful of our family, never making myself, my wife, or 3 kids feel unsafe at any time. Even with the changes to the scope of work, Andrew and his team made good on the timeline of the project, completing everything in 3-4 months as promised when we started. The layout and design of the remodel and addition have surpassed our expectations, everything that we did has really made our home both more beautiful and more functional. I would highly recommend Treiber Building and have done so to several family members and colleagues at work. The experience was as positive as I couldâ ve hoped and the results are outstanding."

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