"Vic turned a flood nightmare into a home we love. Our house flooded while we were out of town and we spent almost a year fighting insurance, only to get sent a list of their 1 star contractors. Then I found Vic and from our first call I knew he was our guy. He was always on time, kept us in the loop and got right to work. Most of all he's trustworthy. We were living in a hotel and never once worried about our house. His whole crew was great too, especially our super nice flooring guy. We went with every design choice he suggested because he has a great eye and no corners were cut. We moved back in when my fiancée was 6 months pregnant and were blown away. He stuck with us patiently even when we were going crazy. He even got us a baby shower gift and we truly see him as family now. We'll recommend Johnson and Sons to everyone. Thank you Vic!"

"I have really enjoyed working with Ryan throughout the entire process of design and building of my outside living area including exterior shower. I appreciated the way Ryan listens in the early process of providing guidance while also taking some of my ideas and implementing them into his design. Throughout the planning and design, I felt that I could trust Ryan to respond to my questions and take care in addressing all my concerns. Ryan built my house a few years back and after living in it for a couple years, I looked to him to assist in a redesign of a couple areas that were important to me such as a clear story glass aluminum frame. The glass and frame is such a marvel both in its design function but, also in the way of how it’s aesthetically placed to my existing roof lines. There have been several things that I have enjoyed working with him on including his design vision and eye for details. Ryan also works and hires the most qualified, talented and nice people. I highly recommend Ryan and his company, Johnson Custom Builders. It has always been a pleasure to have him on a project."

"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 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 Woodinville, 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.
