Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"Having never used Angi before we weren’t sure what to expect. We had a small kitchen cabinet repair of replacing broken drawer slides on the trash/recycling drawer. Dan’s Carpentry responded to our request for a quote in a reasonable amount of time and came to view the project the next day. Dan arrived on time. After he reviewed what was needed we hired him to complete the job. He went above and beyond by not only replacing the slides, but reinforced some loose joints in the drawer front with extra screws. He also cleaned up the work area. Then he even asked if we had anything else to be fixed. We did have a hose reel that connected to the outside of the house but was falling off. He assessed it and had longer screws in his truck and quickly replaced them. It won’t be falling off anymore. Thank you, Dan!! We will use Dan’s Carpentry again."

"My review of the work I have had done by Thomas Gianni & Sons Inc.. They really did a great job of working on my property. I call their office and asked to get some excavation of removing a couple of tree stumps in my yard and to put down approx. 20 yds. of gravel in an area near my shed. It was just about three or four days and they call me back to confirm to come out the next day, June 22. Their employee came by early in the morning and went over all the project. Figured out what equipment he needed and measured up for the materials and started the work about an hour later. He was very cautious and caring about minimal damaging to the yard. After removing the stumps he graded the surrounding area with the machine to the point where I only needed to rake it out to plant new grass. The gravel was put down flat and clean; not a mess. I would definitely hire them again."

Security Doors questions, answered by experts

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

To choose the best door, start by pinpointing its most important job in your home, then choose the material and style based on that function. Simply put, there’s a world of difference between what an interior bedroom door and driveway-facing entryway door do for your home. Thinking about your door's purpose first, then its look and style, will help you make the right choice and stay on budget.

Solid-core, hollow-core, and panel doors offer options for various needs and budgets.

Bifold doors are one of the most inexpensive interior door options. On average, the cost to install bifold doors ranges between $100 and $300. The door material will factor into the cost as well, with hollow core and solid core being on the lower end of the cost spectrum. 

Check the package of your bifold door. The width shown is half an inch larger than the bifold set. This allows at least 1/4 inch between the side jamb and pivot. When installing the top track, saw the track down to leave approximately 1/6 inch on each end. This will ensure your bifold door folds and unfolds smoothly without getting stuck in the frame.
