If you are tired of your home’s thin, hollow-core interior doors, you can upgrade to new molded six-panel solid-core doors that look better and more substantial, and reduce the transmission of sound.

A molded passage door can create a quieter and more peaceful place by eliminating the noisy hum of a dishwasher, the drumbeat from a stereo system, or any other unwanted sounds.

A carpenter will charge $654 to remove a standard-sized interior door and replace it with a new sound-deadening door. That includes labor and material. You can buy the door, hinges and lockset to replace the old door yourself for $245, saving 63 percent.

The job involves removing the existing door and hinges, installing new hinges on the door and frame, and hanging the door. Pay attention to the location of the hinges and be mindful installing the new ones. Make sure they face the same direction as the old ones and check that the new door has the cutout for the door knob in the same place. If the old knob is in good shape you can remove it and reinstall it on the new door and save a bit.

You’ll need basic carpentry tools and a work surface to lay the door flat to install the hinges and finish the surface (if necessary). Allow for about 3/16 inch of clearance on the door width. To trim the height to fit, be sure the door clears the floor surface and any carpeting. Seal any cut surfaces with an effective coating suggested by the manufacturer.

Always mark the Top and Bottom of a door so you won’t make a mistake we’ve made trimming down the wrong end. It’s an easy mistake to make because often as trim down a door you have to move it off its hinges carry it to a work area and then plane down the surface. If you mark the door, there’s less chance of cutting off the wrong end.
