"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"

"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."

"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. We are pursing a Small Claims case against Justin Gibbons. See photos for evidence."

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.

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!"

"We had an outstanding experience with Sean and Bzr team. From the initial call with Gaby to the finished product. I highly and strongly recommend BZR. We first started with a bathroom addition and ended up with an ADU project which turned out great adding a kitchen and 3/4 bath. It did take time and many changes, I want to thank Sean for his patience. I would absolutely in a blink work with them again. I will upload photos when wife has finished furnishing."

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