Common Interior Door Service Questions

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

A heat source close to the door can help reduce its swelling. However, this will only work in the case of minimal swelling. Sometimes, you can simply wait for the weather to change, but your best option is to prevent the swelling in the first place. Coat the door with weather-resistant paint or a water-repellent finish.

Measure the opening, secure the top track, attach the jamb brackets to the bottom of the frame, connect the bifold doors, tap in pivots, insert doors into the track, adjust door height, then attach door knobs and other hardware. If you want to paint your door, make sure you do that before mounting the door onto the frame.

You should prime interior doors before painting for the best results. If you do paint directly on the wood, you could see some of the grain patterns show through the paint, in which case you’d need to apply additional coats. Priming the surface before painting will reduce the number of coats and can better cover the grain pattern for a clean, finished look.
