"Anyvision and Chase were excellent! Their bid was competitive, and their contract was clear and straightforward. What began as a simple shower pan repair turned into a full master bath remodel and a new roof due to water damage. Having dealt with poor contractors for 45 years, we feared the worst, but Chase handled everything seamlessly. He assessed the damage, adjusted the plan, and had the skilled crew to execute both repairs and high-quality finishes. The team was punctual, professional, and kept our home clean. Chase’s tile specialists did exceptional work—no metal edges, just beautifully mitered finishes. With the remodel being unexpected, we had to make quick decisions, but Anyvision’s designer and CAD renderings helped us visualize everything. Chase was onsite daily, keeping us informed with updates, photos, and videos. Challenges arose, but Chase managed them like a pro—offering smart design input, controlling costs, and maintaining quality. This was the best contractor experience we’ve had in the PNW. Anyvision is the real deal, and we’d hire them again in a heartbeat. Their communication, expertise, and customer-first approach set them apart"

Current Super Service Award Winner for 2019 seven years running! Johnson Custom Builders is a Design Builder. Our approach is simple. It all starts with listening. We work closely with our clients to understand everything from their needs to their design preferences. Then we go to work helping them exceed their goals. www.johnsoncustombuilders.com Our process is completely transparent. Our estimates are designed to provide realistic expectations not best-case scenarios. For us, communication is key and we keep you completely informed every step of the way communicating in a way that helps you anticipate and act to effectively engineer the best possible solutions every step of the way. At Johnson Custom Builders our approach is never just about managing timelines and budgets its about delivering on promises and helping you realize dreams. One look at a Johnson Custom build and you'll immediately understand why so many discriminating customers recommend us to their friends looking for a higher level of customized home building. It's not just about the attention to detail or use of the highest-quality materials or even the custom-crafted details. It's about the personalization. Personalization that comes from a builder that not only knows how to listen but also how to anticipate, communicate and most of all deliver on a promise. A native of Kirkland, Washington, founder Ryan Johnson shares the same core values as the community he has always called home: Integrity, Honesty and Originality. He's been actively designing, building and remodeling homes in the area for over 25 years. And in that time, he has earned a stellar reputation for providing outstanding results crafted with uncompromising integrity and quality. Hes also earned a reputation for delivering on his promises. A+ rating on the Better Business Bureau (BBB) !

"Since I now need to use a wheelchair, several doorways in my home needed to be widened. Two exterior doors had to be replaced, one of which also had to be changed to open out rather than opening in. I hired Johnson Custom Builders and was absolutely delighted with their work. They were always professional. They laid or hung plastic sheeting to contain the dust they created, then at the end of the day they ran the vacuum and even mopped the floor! They were respectful of me and my home. Their work was excellent. One of the things I most appreciated was Ryan Johnson's communication with me before, during, and at the conclusion of the project. He listened to what I needed and then figured out how to make it happen. I recommend Johnson Custom Builders highly!"

"Justin Gibbons owner of Carpenters Unlimited LLC brought an illegal employee to work on our project alone (claims no employees with WA L&I). When mistakes were made, Justin GIbbons blamed the employee, attempted to fix the errors, but did not succeed in fixing the errors. Based on the work Justin Gibbons and his company Carpenters Unlimited LLC provided, we would not recommend Justin Gibbons and his company Carpenters Unlimited LLC to family or friends or anyone else. The work Justin Gibbons and his company Carpenters Unlimited LLC provided was subpar, completed late, required many follow ups from us to get fixed, and resulted in damages.

Kevin came up with a number of possible solutions for the design. We finally settled on a scheme that we were happy with. Kevin was very tolerant when we then changed our minds requiring him to redo some of the drawings. Kevin has also been available to offer help and advice during the construction process."

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