"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

A security door costs an average of $1,400, but costs can range from $600 for a simple screen or steel door to more than $4,600 for a wrought-iron security door. You can also buy specialized locks separately for $200 to $600. If you decide to hire a pro to install your new security door, you’ll spend around $275 to $425 on labor costs.

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.

A prehung door comes ready to install with the door already mounted in its frame, including hinges and stop molding. Everything is factory-aligned, which makes installation quicker and more precise. It’s a smart option if your current frame is damaged or uneven, or if you’re working with a new build. Instead of hanging a door slab from scratch, you fit the entire unit into the rough opening, shim it , level it, and secure it. Prehung doors are a clean, efficient way to install new doors without having to piece everything together yourself.

Traditional sliding glass patio doors can last as long as 20 to 30 years, with proper care and maintenance. A patio door's lifespan will depend on whether the door was installed properly, as well as how much wear and tear it gets over the years. Regular repairs will help it last longer.

Clean glass and frames regularly, lubricate hinges, and inspect seals for wear to ensure functionality.
