Window Door Contractors questions, answered by experts

You have several options when choosing the best lumber for your door jamb. Pine is the most common material due to its resistance to swelling. Fir is strong and durable. You could also go with birch or alder. Any wood with a tight grain will work for this project.

You don’t need to have a door at the top of basement stairs, but having one is usually a good idea. Not only will the door block the view of the basement, which might serve as a play area or less appealing workout space, but it can also prevent children or pets from going downstairs, as well as accidental falls.

Bifold doors are a practical and space-saving option for closets, especially if you're figuring out how to design a closet in smaller rooms. This door style allows full access to the closet opening while taking up less floor space than traditional swing doors. Bifold doors come in a variety of styles, materials, and finishes to match any decor.

As long as you do it carefully, you can sand and restain hollow core doors. However, it’s risky because the veneers on hollow core doors are so thin that sanding and restaining might cause damage to the doors. If you do move forward with this project, sand the doors lightly with a medium-grit sandpaper.

You can often fit a new door slab into an old frame as long as the frame’s in decent shape. The frame needs to be solid, square, and free of warping or rot. The new door has to match the old one in width, height, and thickness, and the hinge and knob placements need to line up or be adjusted carefully. However, if your frame is damaged, swapping just the door won’t cut it. In that case, replacing the entire unit would be the best move for a smooth, secure installation.
