"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."

"We found that the wall in our laundry closet was soft and damp. After opening the wall a bit we found massive water damage. Ray with Lopez Bros Construction responded quickly to our request for quote, came out and assessed the damage, and gave us an idea of what it would cost. He then pointed out the demo work that was needed and offered to allow us to do what we could of the work to save us money. Once the demo work we could do ourselves was done, Ray and his crew came out to complete it and then identify where the leak was. This had clearly been going on for some time as the entire floor and subfloor was completely rotten. Ray coordinated the plumber to fix the leak, remove the water heater that was in the garage on the other side of the laundry wall as it was pressing through the other side. After allowing several days for everything to dry out, Ray and his crew then began building back the floor and the walls. Work was completed within a week. Everyone was professional and careful to keep the mess to a very minimum. Ray communicated everything he found, his plan to fix, and showing progress throughout the project. He always let us decide how far to go (removing the water heater and repairing the other side of the wall was our decision) and never pressed to do any more than what we were comfortable with. The project was much bigger than expected, but the price of the work wasn't much more than what was originally discussed. SUPER happy with Lopez Bros 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."

"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 whole experience was excellent. Chris when to give us a bid. He was very knowledgeable. He told use about the triangle of stove, fridge and sink and flow. He suggested a long narrow window to replace the tile backsplash on an outside wall. It was a great idea. When sit at the new bar between the kitchen and the living room we look out into our backyard. Itâ s beautiful. The guys that did the work are extremely work oriented. They are constantly working. They were thorough, knowledgeable and open to our suggestions and requests. We wanted an additional can light no problem. They were great. They cleaned up every day before they left. They would tell use when they were going to arrive and what they planned to accomplish that day. I have old siding on the outside of my house. They matched it perfectly when eliminated a window. The price of the cabinets was a lot more reasonable the other bids and theyâ re beautiful. What I mentally pictured in my mind on how it would look and the ease of preparing meals in the new kitchen were so wrong. Itâ s at least 10 times better. It still has the same physical dimensions but how itâ s played out. It seems so much bigger. I highly recommend them for any project you need done"

"We are truly pleased with BZR. We had many companies come out and try to corner us into singing with them and Sean was just what we needed. When in doubt do not hesitate to go with bzr. They did an amazing job, the project manager is actually managing and not like other companies they send a guy to sell and have another take care of the job. These guys did real good, very clear and communicative."

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