The average cost of installing a door ranges roughly between $90 and $750. This price will vary, however — which it’s important to get cost estimates from several exterior or interior door installation companies so you know how much your specific project will cost.
For example, the type of door you’re installing and its material will factor into the price. If you want to add side or transom windows, this could raise the price. Other factors include whether you’re installing a standard-size opening or a sliding door, and whether you need to replace an existing door.
A door typically takes a few hours or within a day to install, depending on its complexity and the company that's installing it. It also depends on the type of door, the number of installers and prep work needed. When you’re contacting interior and exterior door installation companies, ask them how long they expect your installation will take.
Many contractors are typically able to install doors. Another type of pro you can contact is a handyman. Handymen are usually capable of performing most construction-related tasks, though they may need certain credentials if they perform structural work. A carpenter may also be able to install your new doors, as well as companies that specialize in door installation.
Installing a door is by no means trivial, but it is doable with the right tools, skills and preparation. The easiest scenario is a door replacement with a new door with dimensions that are identical to the one being replaced. Pre-hung doors are relatively easy to install.
But if you’re familiar with this process, don’t hesitate to hire a pro instead.
The amount of time it takes to replace a door and doorframe is likely to take several hours and less than one day. The old door frame must come out, trim must be removed, and the rough opening may have to be adjusted in size to accommodate the new door. Factors that increase the time needed include larger doors, side or transom windows, damage or rot and installing a door without a provided frame.
