"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!"

"I could tell from the minute Stan Petriyenko of Superior Building Concepts came to give me a bid on my primary bathroom remodel that he was an experienced and knowledgeable professional. He measured carefully, listened to what I hoped to do asking pertinent questions. He also brought up ideas I hadn’t thought of. He provided a thorough and detailed bid. After I accepted the bid he did a fantastic job of keeping me informed on the schedule and this continued throughout the project. I was always informed about what would be happening next on the project and the times he or his subcontractors would arrive. At the start of the remodel Stan met me at the plumbing supply and tile / countertop showrooms and gave me helpful tips and recommendations on products. He next set up dust shielding and floor / carpet protection. The work area and path from the entry door were kept organized and clean throughout. All of the subs used were experienced providing excellent workmanship."

Customers say: Super punctual

"If you need work done on your house, hire Rob. I can’t sing his praises loudly enough. Two years ago, my husband and I purchased a house that is 100 years old. It is in decent shape, but we wanted to do a lot of work to turn it into our dream house. Rob has been our go-to man throughout this extensive process, and we can’t imagine having done it without him. In fact, without him, I don’t think it could have gotten done, or rather it would have been MUCH harder (me having to find people for each job), and slower. Rob can do everything. He has replaced every door in our house, all door knobs, hinges and other hardware, all lighting fixtures. He has updated the closets and replaced closet doors. He has replaced our front door and the entire frame. He took out and then covered over this weird door that made no sense and that I wanted to simply be a wall. We want to renovate both bathrooms, and he will do this, and I know he will complete them in a timely manor and that his work will "

"This is the second time I've used In Your Home. The first was backyard fence and gate building, plus construction of 4 steps from a door to ground level. This time I needed interior painting and bathroom towel racks redone. I cannot say enough good things about IYH. The workman showed up on time and everything was done lickety-split and perfectly. I love my new bathroom!"

"John and Brian of JAW Construction did a complete interior refresh of our mid 1970’s split entry ranch house. They removed two walls to open up the main living area, added two new windows to allow more natural light in and installed new lighting throughout. All the flooring was replaced with hard wood upstairs and LTV downstairs. They replaced every door along with all the trim in the house. They installed a completely new custom kitchen, remodeled both bathrooms, laundry room and added a wet bar area as well as resurfacing two fireplaces. In short they touched every surface inside our house. John, Brain and all of their subs were easy to work with, professional and helpful throughout the 3 month construction project. They were able to work around the inherent flaws of an older house and were accommodating went we changed our minds and asked for changes. They really did work to fulfill our vision for the house. We are very happy with the fit, finish and overall quality of their work and would highly recommend JAW Construction."

"WE LOVE JOSH! We initially hired him to remodel a kitchen after another contractor botched the job. Josh fixed everything and got everything finished the way it should been in the first place! We have since hired him for two more jobs: pouring a concrete driveway extension for RV parking, and replacing some siding and painting the entire exterior of the house. Josh is meticulous and clearly takes pride in his work, he is super easy to work with! I HIGHLY recommend Josh, we will continue to hire him for all of our construction needs!"

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.
