"The installation of our new garage door went perfectly. The team worked efficiently, cleaned up after themselves, and made sure everything looked great. They even showed me how to use the remote properly."

We are an all around commercial and residential construction company. Before me and my wife started S&S Construction, we were both working for large companies in the commercial construction industry. We have a lot of experience getting jobs done on time and on budget. I was a Forman for the last seven years that I worked for Finishes Inc. Everyday as a Forman I learned how to cater to a clients needs and make sure they were totally satisfied with the job they were paying for no matter what problems came about in the construction of the project. Any personnel that works for us will treat you with the upmost respect. Our expectations of our employees and suppliers are some of the highest in the industry. We practice a accident free work place, zero tolerance drug or alcohol use policy,and follow the OSHA, or MOSH safety regulations no matter how small the job is. If you choose to ever work with S&S Construction the experience will keep you coming back time and time again. 240-315-4737

Security Doors questions, answered by experts

Proper installation ensures solid hinges and locks, maintaining home security.

Standard door sizes aren’t one-size-fits-all, but there are common go-to dimensions. For exterior doors—like your front door—36 inches wide by 80 inches tall is typical, though you’ll see 30- or 32-inch widths too, especially in older homes. Interior doors vary more. Bedrooms and bathrooms often use 30- to 32-inch widths, and closet doors can be anything from slim singles to wide bi-folds. Height is usually 80 inches across the board; however, always measure your actual opening. “Standard” only works if it matches what’s already in place.

You don’t need to have a door at the top of basement stairs, but having one is usually a good idea. Not only will the door block the view of the basement, which might serve as a play area or less appealing workout space, but it can also prevent children or pets from going downstairs, as well as accidental falls.

Most modern door knobs will all fit in standard, modern doors, so if you know your door was made in the last 50 years or so, you should be fine buying a standard replacement door knob. The only exception would be a thumb latch handleset for an exterior door, as this type of door knob may not fit your door without drilling a mounting hole for the bottom of the handle. Antique or custom doors might also have different sizes and knob mounting holes, so call in a professional if you don’t believe your door is a standard one.

To achieve the correct opening size for a 30-inch door, add 2 inches to the door width and 2 ½ inches to the door height. For example, if you have a 30-inch-wide door with an 80-inch height, then the rough opening would measure 32 inches wide by 82 1/2 inches high
