"STOP if you are wondering who to hire, think no further because Leonel is for you! Our project was to takeover the work of a previous contractor, Leonel stepped in and boy did he come through...taking on a project that was pulled apart by someone else is hard enough but taking on one such as the magnitude of ours and completing it early goes to show what an incredible craftsman Leonel is. He was very articulate in making sure he was on track and following the guidelines, he communicated daily with arrival times and any access or requirements he might need. The quality of his work is superior, everything looks wonderful and its all thanks to Leonel."

"This was an usual project. It was redoing a mini bar. Hard to find a contractor that would do it or had the time. Homepro was great lead by project manager Shir Hadad. Jumped right in there and took it on and got the job done. Really appreciate their professionalism."

Unfinished Carpentry FAQs, answered by experts

There are a few easy ways to locate a wall stud without a stud finder. First, try knocking on the wall with your knuckles. Most parts of the wall will sound hollow, but when you tap over a stud, it will sound more solid. Alternatively, since studs are spaced 16 or 24 inches apart, you can measure those distances from a corner of the room, which will always have a stud.

Most of the time, you’ll want to use screws on your subfloor rather than nails. Nails can actually weaken plywood, whereas screws can easily penetrate without damage. They also form a more secure connection because of their shape, preventing squeaky floors and tightly holding the subfloor in place. That said, some contractors do prefer nails depending on the type of floor covering because they allow for more flexibility.

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.

Removing a load-bearing wall is best handled by professionals. However, if you have the skill set and decide to DIY the project, you will still need at least one additional person to assist you. Aside from helping with demolition, you'll need another hand to install the new support beam.

A few signs that you need a new door frame include:

  • The door no longer fits properly in its frame and sticks or scrapes.

  • You notice cracks, holes, or rotting.

  • You feel a draft coming from around the door when it’s closed.

  • You find yourself frequently needing to make repairs.
