"Just had our kitchen remodel completed by them and couldn’t be happier! Job was done in the estimated timeframe and on budget. Stan was great to work with. He made great recommendations when we were unsure or stuck on something, and kept us well informed on timing and any issues that came up every step of the way. He and everyone he brought in were very professional and worked hard to get the job done. We are already planning to have more work done by them in the near future. Highly recommend."

"Rob responded to my bid request almost immediately. He was able to come out very promptly to evaluate the work I wanted done. He was very professional and gave an honest and reasonable appraisal/bid right away. When he came to do the work, he called ahead to notify me that he was on his way over. He did a thorough and very neat job, cleaned up his work site before he left. I was very happy with the work he did and look forward to relying on his company for any future projects, large or small. In addition to doing quality work, being professional, honest and trustworthy, you can tell that he loves what he does!"

"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!"

Small jobs welcome

"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."

"There are few words to describe how pleased my wife and I were with the
work that Jay Bemis at Timeless Construction did on our recent remodel
and addition which took place in 2015- 2016.  After interviewing several
contractors we chose to work with Jay.  It was clear to me from our
first meeting - he had the ability and experience to do the job.

Our project was large in scale ($600,000 + ) technical, complicated, and
very challenging with many moving parts.   The addition of nearly 1000
sq feet to our home required the complete removal of our roof  and
rebuilding of much of the existing structure.  In addition, we did a
complete kitchen renovation, outside deck, new roof, and a concrete
patio.  Jay was responsible for all phases of the project; from
excavation, foundation, framing, electrical, plumbing, A/V etc., to the
finish work.  We were extremely happy with his eye for detail and
quality of workmanship.  

This was true, not only for himself and his crew, but for all his subcontractors. 
His crew and his subcontractors were on the job site and - on time - everyday, respectful
of my home, my family and our needs as we lived in our home as the
renovation and construction took place over 15 months.  This being my
5th remodeling experience - working with such a crew was a pleasure!

I found Jay?s pricing to be more than competitive and his input and
options to be rock solid.  He was easy to work and his constant
communication on the project was refreshing.  He was on the job site or
involved with the work underway on a daily basis. 

It is without hesitation that I would recommend Jay Bemis to anyone considering a
construction or renovation project; you simply can not do better."

"During wind storm a tree fell on out buildings. A garage and 2 sheds. This company was fast in tarping garage roof to keep rain from getting in. Also, Anwar was quick to give estimates on repairing garage roof and sheds. His crews put new roof on garage and sheds as well as replacing broken rafters caused by the tree. They prepped and painted garage and sheds. They look brand new. Anwar interfaced with my insurance company to get additional considerations from the original insurance estimate. I was especially appreciative of his help. You can't go wrong by hiring Dluxe Construction!!!"

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.
