Hiring An Interior Door Installer

Unless you have prior experience, it's a good idea to hire a handyman as installing a door has many pitfalls, can be tricky, and requires a high level of skill and patience. Professionals will install a door in 1 to 4 hours, but plan on it taking much longer when attempting it yourself.

DIY Tips & Considerations

If you are unsure where to start, learning from a professional is the best way to prepare yourself for future DIY installations. Take time to learn about all the various door styles, and consider the following advice:

• Find DIY installation videos directly from the manufacturer or ones with the highest number of positive reviews.
• Gather all the tools and materials needed, including screwdrivers, hammer, sledgehammer, jamb level, square, drill and bits, utility knife, a four-foot ladder, level, handsaw, miter saw, tape measure, wood shims, and a box of 3” screws.

Common DIY issues when an installation doesn’t go to plan include:

1. Unable to latch – Not leveling the door before installation may cause the latch bolt to not line up with the strike plate. This prevents the door from locking, and it may open on its own. A professional will have to relevel the framing or redrill the holes.
2. Door doesn't close or stay open – Uneven framing prevents the door from closing correctly or staying open, which requires a complete reinstall.
3. Incorrect measurements – If the door is too large for the opening, it may drag the floor or sit unevenly at the top.
4. Trim and casing damage – Sometimes, the trim and casing don’t line up with the door, or it has been damaged from installation. New trim costs $2 to $4 to install.
5. Screws don't hold – Too many attempts to repair any mistakes causes the strike plate or hinge screw holes not to hold screws anymore.

Benefits of Hiring A Pro

In most cases, it makes more sense to hire a door installer for an average cost of $100 to $300 with discounts offered for installing multiple doors during the same project. Professionals ensure your door is level, latches, and opens and closes properly.

Before hiring a pro, be sure to:

• Ask friends, family, and neighbors for references or compare pros on HomeGuide.
• Get at least 3 price estimates.
• Verify reviews on HomeGuide and Google.
• Check the Better Business Bureau for their reputation.
• Never pay upfront, and avoid paying in cash.
