"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."

End product looks great. My neighbor was so impressed when she saw his work that she hired him to clean, sand, and stain her deck too."

"Ryan Sharp did an awesome job taking down some huge trees on my property. His pricing was competitive. He worked quickly and safely and was able to get the job done the right way. You can feel confident having him and his team knock down any trees that you need gone. Hire this guy."

Carpentry FAQs, answered by experts

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.

Bump-out additions can add some space to a closet without requiring any significant structural work. This entails pushing back the existing rear or side of the closet, simply moving the wall into either an adjacent room or unused space. For ground-floor closets, this could even be extended to the exterior of the home, but that has its own complications. Bump-outs are a good discussion to have with your contractor if you’re just looking to increase the space a little—not renovate the entire closet space.

Not all porch columns are load-bearing, though they can be. Some porch columns are simply decorative. There are ways to identify a load-bearing column, like looking for visible seams and a foundation. Also, check to see if the column directly enters the ground. In some porch installations, a contractor will excavate a hole to install a column into the earth along with a buried cement base for stability.

Installing an ornamental or decorative porch column takes around three to five hours. Structural columns take longer because your pro has to install a jack to hold up the roof while switching the column out. If there's any structural damage, it can add several days to the timeline to repair the damage.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.
