"Started out well. Job started earlier than originally planned which was fine. Paid a third down to start job with understanding that rest would be paid in full upon completion. Everything was going fine until near the end of the job. After shower fixtures were installed I noticed they were the wrong finish from what we agreed on for the estimate. Took a week for Joel to reorder & replace. When the frameless glass shower panel was going in, the installer realized it was the wrong size, and had to be redone. The grout on the stone shower floor was very sloppily applied. Bits of dried grit are stuck on the stones. Before job was finished Joel was asking for full payment as he was running tight of money. I insisted on paying him in full only when job was complete. He wasn't very happy. Overall, the tile shower walls & bathroom floor tile look great. I only wish there had been more attention paid to the other details."

I moved from a farm into a new house in a small town. They built four more homes next to our house and I told my parents I want to do that when I grow up. For the last 33 years I’ve been doing just that . I guess you can say “ I’m living my dream “. I do my best to listen to my clients and help them with the vision they gave for their. Communication from start to finish.

"I would highly recommend them!"

"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."

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.
