"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."

Window Door Contractors questions, answered by experts

High-tech solutions and strategic placement can help ensure the safety of your pet door. Pet doors can pose security risks, as well as the risk of stray or wild animals entering your home, but modern pet doors offer options like collar-based sensors to ensure doors will only open for your pet, and installing a pet door in an out-of-sight location or in a wall rather than a door can help to avoid intruders using the door to gain access to your home.

While sometimes used interchangeably, a screen door differs from a storm door. Screen doors are composed only of the frame and screen, whereas a storm door has more components. A storm door comes with a glass panel that can be installed instead of a screen to keep the air inside the home. A storm door offers more protection , but costs more than a screen door, so weigh the pros and cons to determine the best option for your needs.

Security doors are not limited to standard sizes, and you can customize them to fit your needs and entryway dimensions. That's one of the fantastic things about security doors—they can be tailored to match your home. Keep in mind that a custom-sized security door will likely cost more than a standard size. 

Installing a dog door is generally a straightforward process that handy DIYers may feel comfortable attempting on their own. Because the process usually involves cutting a hole in your existing door or wall, some homeowners may prefer to hire a handyperson who has experience with this type of installation to ensure the job is done right.

A screen door needs at least two hinges, though most have three or four hinges. The amount of hinges depends on the weight and size of the door. The heavier your door, the more hinges it will need for support. Exterior doors, which are sturdier than interior doors, have the most hinges.
