"After completion, Ben personally came back to walk through everything and check finishing touches. That follow-up meant a lot. The project was completed on schedule and within the agreed scope. If you?re considering a serious home addition, this is the construction company you want managing it."

"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."

"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!"

"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."

"They did excellent and thorough job. The quality of work was very impressive. Ray Lopez was easy to work with, very flexible and truly cares about the customer. I'm so lucky to find a company with such integrity, that's honest and hardworking. I will definitely hire them back to do more work and refer them to my family and friends.

"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."

"We were really impressed with Classic Remodeling. They did full updates on our bathroom and kitchen and we’re thrilled with the results. Their main contractor Russell is super responsive and was respectful of our budget - we never felt like they were trying to up-sell us. Both projects finished on schedule and look fantastic. We would recommend and use them again."

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.
