"Punctual, clean, and great pricing. Bob was great. He arrived on time, cleaned up and was extremely polite and courteous to my family. Bob installed two outside doors and they look great. We will be using New Edge Carpentry again for more work around the house."

"Pro Master Construction company is the absolute best company I have hired in over 35 years. Luan came to my house, was very considerate, caring, and knew his business. He solved a nearly impossible problem with an almost rotted and very large 2-tier deck. His crew did an amazing job in just under 3 days. Great work ethics, reasonable cost, and very neat. I am so thankful to have found this company on Angiâ s list."

"Walter from Jag construction has done a few projects for us as well as some commercial work at our building to mention a few. We started with our commercial property in Smithtown. He came in and went right to work and the timeline was fantastic. We called him to our home to finish our basement thereafter. I was so impressed I also had him reconfigure our first floor laundry room as well. This year he’s doing a few more projects here! It’s not everyday you find a professional that treats your home like his own and his recommendations are always well planned and precise which to me is greatly appreciated. I can’t say enough good things about this contractor and would have him do any project beyond my scope at either our home or business alike. A++++ Frank and Mary O’Donnell Speonk, NY"

Carpentry FAQs, answered by experts

It's possible to turn your carport into a living space, but there are additional factors to address over turning it into a garage. HVAC, plumbing, and electricity won't be optional, and you'll need finished flooring, drywall, trim work, and legal ceiling height, for starters. Also, keep in mind that living space conversions may require upgrading the foundation underneath, and the permits might be more expensive as well.

You should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.

It’s best to use two screws to secure deck boards into every joist. Securing the boards to every joist makes the deck more structurally sound, while using two screws on the outer sides of the boards can help prevent warping and cupping.

When hanging a door frame, it’s recommended that you use screws, not nails. Screws are more secure, easier to tighten, and easier to remove if you need to adjust the frame. On average, the cost to replace a door frame is about $400, but you can save on labor costs if you’re confident in your ability to DIY the project. 

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.
