"We very enjoyed working with Ihor and his crew, all of whom were immensely respectful to our home, focused on performing quality work with an eye for detail, and surprisingly quick in completing the job without cutting corners. Ihor's communication throughout both projects, the deck build and basement leveling/flooring, was specific and timely. I have no hesitation in recommending Ihor and look forward to working with him again when the next project calls."

"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"

From the beginning Edward took the time to hear all the details of the project and understand them, he also was very helpful with offering ideas when I was unsure of some of the design details. He has a good eye for excellence and didn't miss a detail. Edward and his crew were very professional, personable, respectful and cleanly.

At Classic Remodeling NW. Inc. our mission is to build lifelong family relationships with our clients, co-workers and community neighborhoods through the remodeling process. Our guiding principles are those of commitment, honesty and personal accountability through a high level of communication and respect for one another. We can build or remodel any part of your house to make your dreams come true! Communication is a tool we use every day to make sure we know what you want. We keep your home neat and clean the entire time we are working and make sure that your satisfied. With Classic Remodeling NW Inc., you are not just a customer, you are family. Our team gets to know you personally so we can make sure your dream will come to life and you will be more than satisfied with the results, and the cost! We build our team on "Honesty, Ethics, and Morals". Let us show you the Classic Remodeling NW Inc. difference!

"I am a repeat customer, so I knew the carpenter, Joe, coming in. I started by using their design contractor. I gave her the colors and ideas (beach theme, ceramic wood-look floor tiles), and she pulled the rest together. Invaluable because I can't trust my own taste. They removed a square shower in the corner and a set of shelves next to it, and glassed in that end of the room for a full shower. We put tile down along the whole room, with a recessed shower pan, and a linear drain against the wall. Joe built-in medicine cabinets, and trim all around the room, per my design pictures. The subs included a glass door guy, the plumber, the tiler, painter, and the countertop slab tiler. We also had some work done in our hallway. They removed the single boob light from the middle, and installed two recessed lights on either end, along with putting two switch boxes on either end of the hallway. Joe built a floor to ceiling cabinet in a 13” dead space at the end of the hallway, which included a laundry hamper on tracks, cubbies, and shelves. And then on a whim, I asked to have our old hallway linen cupboard doors replaced to match the new ones. We had two leaks during and after, but one reason I would use them again, is how they handled both times. One was a leak from the plug on the toilet supply. We found it on a Saturday morning, and I ended up waking up our carpenter with my text. He came out and figured it out and fixed it by 1. The other one was after everything was done and cleaned up, and we had paid for everything. The basement bathroom ceiling, fan, and wall below the master was wet one day, and we realized a joint in the pipe from the master toilet to the stack was slowly dripping between the two rooms. I texted Joe again, and he referred me to our GC, who came out with a plumber and fixed it. They had to make a hole in the downstairs drywall, so he has been coming back regularly to put three layers of mud on the new drywall. I was so sure that they would regretfully find that it wasn't their fault and we would have to deal with the cost and bother of finding a plumber and carpenter. Start to finish, it took about four months, but three weeks of that was the initial tile order, and another three for an incorrect tile order."

"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 Duvall, 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.
