It's easy to add a replacement door. Just take the old door off the hinges and add the new one, right? Not always.

Replacement doors can be tricky to install because must account for the size of the door and the frame. Do you know how to make the door level? Will a replacement door fit in the old framing, or will you have to trim it? These unknowns are precisely why many home owners let remodeling contractors handle their replacement doors.

Advantages of Prehung Doors

It's usually best to buy prehung replacement doors that include framing, though it depends on the door and your space. This way you know that the door and framing will fit together. Prehung doors are sold in standard sizes that fit most openings.

The Door Opening

It can be difficult getting prehung doors to fit, particularly in older homes with damaged or uneven frames. You may have to take off door molding, trim it to fit, and then reinstall it, for example. It may take an experienced remodeling contractor to smooth out these kinks.

Replacement Door Options

As you consider buying replacement doors, ask yourself whether the door and framing are in good shape and are a standard size. If so, then you can probably replace the doors yourself, assuming you have the carpentry skills and tools needed.

DIY home projects are valiant, but know when you're getting in over your head. If you notice your door or frame is an odd size or needs work to make it usable, call a remodeling contractor for installation.
