"Stan and his crew did a beautiful, thorough, clean and detailed job rebuilding our 14x30 ft deck. He walked us through the whole process in buying trek, what to look out for and he did such a great job that my neighbors across the street hired him for their deck. Stan has done so many projects around our house (remodeled bathroom, replaced door wall, front door, replaced some of our siding and so much more) and we’ve been so pleased with everything he’s touched, it’s a no brained we let him do our deck too. You’ll never be disappointed. He doesn’t change the price on you mid project and he’s very reliable and always finishes when he says he will."

"Looking for a contractor for your remodeling job? We give John Wood five stars. We hired John Wood of JAW Construction to transform a building shell originally intended to be a shop for building trusses into a small house (officially an auxiliary dwelling unit or ADU) and are thrilled we found him. The job required skills that extended beyond new construction to include the insight, skill and craftsmanship of a highly experienced remodeling expert. He possessed these in spades. Beyond his own expertise, he has assembled a set of sub-contractors that are excellent craftsmen in their own areas of expertise. The job was doubly challenging given that for much of the construction period we were out of state getting our old home ready for sale. This also meant that an extra element of trust was involved. John sent us pictures of the progress, so that we could monitor from a distance. In addition, he was able to identify and rectify several flaws in our design. As with any large construction/remodeling project, there were some unexpected expenses that came up, but John worked with us to help limit cost overruns, sometimes foregoing profits. He was also always up front about the costs of the various components. Our new home is gorgeous and reflects his sharp eye for detail. We couldn’t be happier. In short, if you want a highly skilled, trustworthy, hardworking contractor for your large (or small) job, we highly recommend John Wood of JAW Construction."

"We hired In Your Home for a laundry room / mudroom reconfiguration / reno and they did a terrific job! I love that they are a small, locally-owned company, specializing in ADA renovations for the elderly and disabled. Everyone who works for IYH is very attentive and accessible. Time from demo to completion was 3 weeks. Had a great experience working with Kristen (consultant / designer), Lee (project manager), and Israel (demo, framing, drywall, flooring, etc.) Electrician, plumber, and cabinet maker were contractors. We had a few small hiccups along the way (as always happens with a remodel) but staff were very prompt and courteous to resolve them. They hire quality people and take pride in what they do. Would definitely recommend!"

"We hired Steller Construction and Remodeling LLC to build a deck/Catio in May 2024. Micha (the Owner) was straightforward to work with and reach throughout the process. We are retired and live on a set income. Even though we had some lower estimates from other companies, we felt so confident with Micha's (the owner) ideas that, after looking at other reviews/images of this company, we decided to go with Steller Construction. Micha's team was absolutely amazing !!! Ray, our project's lead employee/carpenter, was very knowledgeable, considerate, and had an unbelievable work ethic! The rest of the team did an awesome job as well. They communicated well throughout the whole job always checking in with us to make sure they were doing what we wanted. They were professional and very polite everyday. At the end of each they completely cleaned up the area. We have worked with one other construction company and a roofing company when we did some remodling on our last home and did not have a good experience with either company. We were very nervous about having to go through another bad experience. We were so pleasantly surprised that Steller Construction turned out to be a great decision! Our deck/catio is beautiful and we love it! If you have any construction/remodeling needs contact Micah at Steller ConstructionI you will not be disappointed!"

"We couldn't be happier with the overall service and quality of construction. We converted a space for multi gen living that included removing and adding exterior doors and windows along with interior wall removal and builds. The process of scheduling trades was seamless, and work was completed within 2 1/2 weeks. Our neighbors are loving the new exterior look which included a ground level deck for zero entry (no stairs)."

"Dluxe Construction built an ADU for us. Our contractor Anwar took the time to figure out exactly what we wanted and he and his crew made it come to life. He responded to me whenever I reached out. He is an excellent communicator and listener. He has a strong work ethic and takes the time to get every last detail correct. And he does these things in a timely manner."

FAQs for addition to existing structure building service projects in Portland, OR

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.
