"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!"

"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!"

"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."

"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."

"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."

"The group performed a good job updating our old bathroom. They gave sensible design advice and took care to avoid plumbing issues. Coordination should be improved and there were a couple material delays. Overall, the makeover was respectable but the communication was mediocre."

"Allan is a highly skilled, hard-working, smart, reliable and honest contractor who attends to details—and has a great sense of humor. He did most of the work himself but also hired and worked well with sub-contractors. He started with our garage, creating plans for a remodel with the help of an architect and then precisely implemented those plans. He went on to demolish our old kitchen (to the studs and sub-floor) and rebuild it, according to architectural blueprints. The job required reframing three windows, building walls, putting in a new fir floor, installing cabinetry and a very heavy but beautiful hood/vent, installing appliances, tiling and painting walls, window frames and a box-beam ceiling. A complicated part of the job was building a permanent buffet with rounded corners and tempered glass inserts which he did well. He also built walls and laid flooring in our laundry room. We feel so lucky to have found and worked with Allan, and we’re hoping to be able to work with him again on future projects."

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