"I recently hired Devin to reside my house and replace the front door, and I couldn’t be happier with the results. From start to finish, Devin was professional, reliable, and easy to work with. He clearly takes pride in his work—the attention to detail was evident in every aspect of the project. When replacing the front door, Devin discovered rot beneath the old frame. He took the time to properly address and repair all the issues around the door before installing the new one, and did an excellent job making sure everything was solid and well-sealed. The final result looks great and feels very secure. The new siding also came out fantastic and really improved the look of my home. Devin was flexible throughout the project and accommodating with any changes, making the entire process smooth and stress-free. If you’re looking for a contractor who does quality work and genuinely cares about the finished product, I highly recommend Devin."

"Cody and company worked for us in the fall of 2019 getting the exterior of our new (but very old) house in shape before winter. Cody was extremely thorough in preparing the house for painting, and in repairing both, some damaged siding we were aware of, and other areas of rot that were more extensive then we knew. There was a lot to finish as the colder weather set in, but it was clear that Cody wanted to do things the right way without cutting corners. We selected a bolder variation on the previous color scheme, and the finished project looks fantastic. Cody was respectful, easy to communicate with, and fair and transparent in his pricing. We plan to work with him again on other projects in our home, including interior painting, and we recommend him and his crew without reservation."

"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

Doors FAQs, answered by experts

A hollow core door has an average life expectancy of about 20 to 40 years, with most lasting 30 years before they need to be replaced. Doors that are well cared for can last on the longer end, as long as no severe damage occurs.

If a wooden door swells from temporary humidity or moisture, it should return to its original size as the environment dries out. However, if the door remains swollen due to prolonged exposure to moisture or water damage, it may not fully revert to its original shape and could require repairs or replacement. Using a dehumidifier and ensuring your doorway has good ventilation can help prevent and reduce swelling in wooden doors.
