Window Door Contractors questions, answered by experts

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.

Minor modifications like grab bars and threshold ramps can be DIY, but professional services ensure compliance with ADA standards and structural safety.

Yes, pros can match styles and finishes to align seamlessly with your home.

While doggie doors are convenient for pet owners, they do offer a few drawbacks. For instance, they’re small enough that unwanted critters could come into the house, such as raccoons, snakes, rats, and insects.

They’re also large enough that small children can escape through them, which can be a serious concern to parents of young children.

Finally, doggie doors can make it difficult to regulate your home’s temperature because they constantly let in hot or cold outside air.

Yes, pros adjust frames and guide rails to fit unique dimensions.
