"We had water loss in our house. In addition to the restoration work, we decided to do a broader remodel at the same time. We actually hired a different company that promised to make our house all new again, but we had a lot of delays and communication issues, and ultimately walked away from that company. We had already moved into temporary housing for the remodel, and needed another contractor to step in quickly. Johnson and Sons rose to the occasion and were able to get us back into our house quicker than the first company would have. Our remodel was basically the whole house. Floors, interior paint, all 3 bathrooms and the kitchen. The price was competitive. The timeline was good. The communication was outstanding, which was very important to us. Vic was always available to answer questions and proactive in letting us know what was going on. Jon and Tony were patient and willing to make adjustments as requested. We did discover an issue based on a previous contractor's faulty work, but Vic was quick to explain the situation and give us options and prices. We would definitely recommend them to others."

"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."

"recently hired Northwest Builders & Renovation to build my garage, and I couldn?t be happier with the results. From start to finish, their team was professional, responsive, and detail-oriented. The communication was clear every step of the way, and they delivered exactly what they promised ? on time and within budget. The quality of the framing, concrete, and finish work exceeded my expectations. They took care of everything efficiently, handled permits smoothly, and left the site clean every day. It?s rare to find contractors this reliable and dedicated to doing the job right. I highly recommend Northwest Builders & Renovation to anyone looking for skilled, honest professionals who truly care about their work."

"The owner Ballard is very responsive since the first time we contacted him to schedule for an estimate, and until the last day of the project.  
His crew Jason and Shannon are very punctual, and arrived exactly at 8 am as they said they would.  
They did a beautiful job on the window frames and trims.  They were very careful and did not damage anything, and the finished work is excellent.  
It was very easy to communicate with all 3 of them, and they are all very polite and very informative too.  
We purchased a deal that they had going on from Angie's List which included 40 hours of labor for $1899, excluding tax and materials. They worked for 2 days because they had 3 people working the first day, and 2 people worked the 2nd day.
Originally, we had more things on the list for them to take care of, but when they opened up the damaged wall in the dining room, they discovered that the damage was much more extensive than they had expected, which took up more time than originally thought.  So we were not able to have everything on the list fixed. Nevertheless, they tried to meet our expectations to finish as much work as possible in the 40 hours.  
They cleaned up really well after the work was completed.

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.
