"We hired Topline Builders and Renovations for a full home addition, adding nearly 600 square feet to our main floor. From the very first consultation, Ben walked us through the architectural plans, structural requirements, and permitting process with the city. We were nervous about taking on such a large construction project, but they made it feel organized and manageable. The framing crew worked efficiently, inspections passed without delays, and the final finishes blended seamlessly with the existing structure. You honestly can?t tell where the old house ends and the addition begins. Communication was consistent throughout the entire process. This wasn?t just a contractor showing up ? this felt like a professional construction team managing every detail properly."

"Johnson and Sons have done many major construction projects on our house. The latest was building a back porch with a landing. From working with us about the design to the finished project each step was of the highest professional level. Vic and Matt are amazing and their crew were skilled, hard working professionals. Johnson and Sons will always be our choice for expert construction projects."

"JJ construction was my #1 choice for remodeling. I made my appointment with JJ construction. The person showed up on time and very thorough. We were very pleased by their expertise and their advice. However, I decided to sell the house as is. No work was done on my house. But I do recommend this company for future projects."

"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!"

"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."

"PRORAB Construction & Remodeling painted our house exterior last summer. The price was reasonable, and the work was done quickly and very neatly. Everything looked professional from start to finish. I would definitely recommend them to anyone looking for quality painting work."

"CJ did an amazing job helping me break my project down into different phases. He made sure the work area was clean at the end of each day. I appreciated his attention to detail making sure that the door instal was perfectly square/level. He was extra careful to salvage my unique siding to re use around a window, which saved money. It was installed so perfectly you would have never noticed the window changed at all. My kids were so excited to watch him and he was so good giving them leeway to watch while still making sure they were safe and staying out of his way."

"The group performed a good job updating our old bathroom. They gave sensible design advice and took care to avoid plumbing issues. Coordination should be improved and there were a couple material delays. Overall, the makeover was respectable but the communication was mediocre."

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