"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."

"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!"

"Pros: The employee who did the work did a great job, he was left alone to work on the house most days and only had help for a short period. They worked with the customer to pick a plan and did not force anything without agreement of the customer. Cons: Was difficult to work with when something changed. Their electrical contractor misquoted codes and when brought up that I didn't want him doing the work (as he was attempting to charge an additional $4,000.00 to move the breaker box that was not necessary) it was difficult to have the estimate reflect that work was not being done. It appears that they do not have a cost per line estimate system that they can provide to the customer if requested. Also it seemed as though they took his job as a second job to do when they didn't have something better. There were times that I wondered if the contractor would even show up and what was quoted as a 7 day job ended up taking close to 6 weeks. Also have not finished adding the privacy glass in the bathroom window as was ordered. They advised the window store messed up and they would be out to fix the problem, this was approx 1 month ago and I haven't heard anything to date. Overall - Good Builders but don't plan to have great communication or the job completed on the timeline they gave."

"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."

"I hired Iconiq Construction to do my kitchen and I?m really happy how it came out. Sean and his guys were great, they told me what?s going on all the time so I never had to wonder. Everything went smooth, no waiting around, no extra money they ask for later. The kitchen looks so good now, better than I thought, and I?m glad I went with them."

"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."

"An appropriate replacement stair was provided and carefully installed. The politeness and courtesy of the skilled installers was simply outstanding. The custom work in fitting the stairs to the existing attic opening was a marvel of workmanship. The cleanup of the area was extremely thorough. We would hire GMG again without hesitation. We highly recommend!"

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.
