"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

Most of the interior doors in your home are the same size. For example, most bedroom doors may be the same size. However, your closet doors might be the same size as each other but are a different size from the bedroom doors. You might also have bedroom closet doors that are a different size from hallway closet doors. It’s best to be safe and measure any door you want to replace.

French doors that open to exterior spaces are often installed to swing inward, as this makes them more secure than outward-swinging doors, due to the interior hinges being inaccessible from the outside. For interior doors, it’s personal preference which direction to hang your doors, but it’s common to have them open into the larger of the two spaces they’re separating.

Yes, barn doors can be too heavy, although the limitation is usually imposed by the mounting hardware you buy and not your home’s framing, unless you’re building an unusually wide door. To keep the weight down, you can opt for 1-by material rather than 2-by material, and choose a softwood like pine rather than a hardwood like maple or oak. Check the weight limits on your mounting hardware, and always attach your door track to studs rather than to drywall anchors.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

The lock block will either be built-in on the side of the door or run from the top to the bottom. Usually, there is a marking that indicates its location. You can also tap the door with the back of a screwdriver to find the lock block like you would find a stud in a wall.
