"Entire process exceeded my expectations from the initial contact I had with Alliance to the completion of the project. The proposal I received from Keith provided the level of detail I was looking for and he did a great job in going over the siding products Alliance offered to detailing all the necessary steps in the process. The installation process went very smoothly and was completed in a timely manner. The crew led by Serg were extremely professional, knowledgeable and focused. I could not be happier with the work they did and Serg kept me updated on how the project was progressing and was quick to reach out to me with any questions he had on the proposed installation approach. Therefore, I would recommend Alliance for any home improvement needs that you may need addressed. Lastly, I was so satisfied with the siding installation Alliance did I am now having them replace the two entry doors to my garage. Thank you again Sergiy, Keith, Serg and the rest of the installation crew. CFP Sr."

"Total Remodeling just installed my new sliding glass door, and I couldn’t be happier! The quality is excellent, and it completely transformed the look of my space. The team was on time, professional, and made sure everything was done perfectly. It opens and closes so smoothly, and the installation was quick and clean. I highly recommend Total Remodeling for anyone looking to upgrade their doors or windows!"

Doors FAQs, answered by experts

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

You want plenty of room between your pre-hung door and the framing in your wall to allow for shimming to get the door into the perfect position, so aim for about 1 inch on the top and both sides. That means you should make your rough opening about 1 inch taller and 2 inches wider than your pre-hung door. You’ll then use shims to stabilize and level the door before installing it.

The most common rough opening for a sliding glass door is 60 inches to 72 inches by 80 inches. A rough opening is the unframed space where your door will go.

You can use a variety of wood to build a barn door, but the most common options include 1-by boards and 2-by boards for the backing and the decorative boards on the front of the door. Softwoods like pine will save you some money and should hold up well, while hardwoods like maple and oak will stand up to more wear and tear. You could also build the backer out of plywood to minimize the cuts you need to make. Whatever you decide on, make sure the width of the wood is compatible with the mounting brackets you buy.

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.
