"We would highly recommend Superior Building Concepts for your next project. After many over priced quotes, underpriced quotes with a wink and a nod to do this small job without permit, or contractors that stopped by to provide a quote that we never heard from again we received a referral from Angie's list for Superior Building Construction.  Stan came by, gave us a reasonable quote then followed up with a very professional and complete contract.  We signed with Superior and were pleasantly surprised with the continued professionalism.  We received compete drawings with architectural choices.  After our selection, it was put through the permit process.  At each point we received proper communication from Stan. Once construction began, Stan was there managing the subcontractors and working alongside.  We were delighted with each subcontractor Stan brought on board.  They were all punctual, courteous and cleaned up everything after their respective jobs were complete. With Covid supply shortages you can imagine some of the issues that arose, but with each roadblock Stan communicated with us and we worked out satisfactory work arounds. This remodel was a pleasant experience and Stan and his team made the difference. You can be confident in your project if you select Superior Building Concepts."

"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!"

"Beautiful fence, quick build, and the price matched the quote. Micah was professional and courteous throughout, and quickly came back to fix a small issue that was forgotten. The only issue was a small financial one- my deposit wasn't deducted from the total and I didn't catch it until after he had left with the check. It took a few weeks to get that money back, but again, Micah always responded and made sure it got back to me. Definitely going to hire again."

"This is the second project that we have hired JAW Construction for and we are very happy with how our remodel turned out. As this was a major kitchen, dining and living room remodel, which meant we were not going to be able to be in those rooms during the construction, John and I worked on the timeline to ensure it went as smoothly as possible. Before the project started, Mark from Amcraft Cabinets came out and measured and talked with us to determine how best to use the space. We came up with several cool options including a pull out spice rack and a lift for my mixer. Once the project began, John, Brian, the electricians Clint, Christian and Tyler and the plumber Mike were always on time, friendly, always available for questions and cleaned up after themselves. John estimated that the project would take six weeks and it ended up taking five weeks! While it was not fun to be without a kitchen, we are so happy with how it turned out, it made it all worth it. Everyone that has seen our remodeled areas or pictures of them are very impressed. I highly recommend hiring JAW Construction and we are already planning our next project with John."

"Let me start by saying, this ADU project was for my daughter, Macy. Macy has I/DD and Autism and will likely not be able to live away from us, her parents, unless she is in assisted living of some sort. However, together with her grandma we sought to create an environment for her to live as independently as possible and for her to grow into. This began our search for the perfect contractor who would understand our needs and work with us to build this ADU for Macy. Enter, Jay Bemis with Timeless Builders. After multiple meetings with contractors, many unreturned calls and emails, we met Jay. He immediately sounded interested and returned with a bid in a timely matter. We accepted this bid and began to move forward with this project. As with any construction project, we ran into unexpected situations. I could not have picked a better partner to handle all of these situations. He maintained focus on finding solutions, worked magic to make things happen that we wanted and came up with additional creative ideas when we couldn’t. He is a true craftsman and he employs the most amazing people! The pandemic hit during our project and he was respectful of our request to wear masks when entering our home. They continued the work and Jay was open about end dates and timelines. If you are looking to start a project, I can tell you that Jay Bemis and his team at Timeless Builders is who you want to partner with. Their work exceeded our expectations, their friendliness was an added bonus and the end result blew us away. Don’t think twice, contact Jay with Timeless Builders, he will help you get your project done right."

"Clearwater Construction services was a great company to work with. CJ was attentive and communicative which is hard to find in this business. Every person that came out was polite and cleaned up very well. The subs they used were top notch and I would use any of them again. They did what they said they would do and did it on time. We were so impressed how they cared for the house while working on it. They treated it like their own. I highly recommend them for any work they can do and I will use them again when needed."

"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 Lake Oswego, 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.
