"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

Fire doors are constructed to have certain resistance levels regarding fire. A traditional door can typically resist fire for less than one minute, whereas fire doors can resist it for 30 to 120 minutes, depending on the fire door rating. Fire doors give you and your family a better chance of safely escaping during a fire than standard doors. 

Longer screws can make a door more secure, but this isn’t a foolproof method for security. Replacing the short screws in your door’s strike plate with screws that are 3 inches long will make it much more difficult for an intruder to force entry by kicking down the door, but it won’t do anything to stop them from picking the lock. 

Most exterior doors swing inward for better security. But a security door will swing outward. What makes it so secure are the one-way screws that go through the door, the door frame or house wall, and into the home. Make sure to align your door so it swings outward, with the door handle aligned with the existing door’s handle.

Your front door should only need replacing every 20 to 40 years, depending on the material and level of wear and tear. Sometimes a door will need replacing sooner due to extreme weather conditions, like a hurricane or storm. In other cases, you may want to upgrade your door to add some upgraded curb appeal—especially when prepping your home for sale.

When it comes to painting hollow core doors, the top recommended paints to use are semi gloss or satin finish. If you do paint hollow core doors, be sure to gently sand the doors and use a paint primer to ensure the paint sticks.
