Security Doors questions, answered by experts

Like many common door problems, warping can be caused by improper installation. When a door isn't installed correctly, there's a good chance that the poor seal is allowing moisture and drafts to seep through. When this happens, humidity will build up in the wood until it swells and warps.

First, make sure the couch and door measurements are compatible. Removing the interior door increases the opening if it's a close fit. You may need to turn the couch on its side or move it in separate pieces, if possible. Your best bet is to use furniture sliders to help you slide your couch through a doorway.

While applying a small amount of olive oil to a door hinge may not cause problems, regularly using olive oil or vegetable oil can cause door hinges to become sticky and gummed up over time. Additionally, residue from food-grade products can actually turn rancid.

Interior door thresholds are usually attached using finish nails, and some contractors will also use construction adhesive under the threshold to hold it in place. Exterior door thresholds are more commonly screwed to prevent them from pulling up when people step on the raised edge on the outside of the door. Exterior doors also include caulk sealant on the inside to prevent water and air from seeping through.

Permits are required when carrying out any structural work, so in most cases, you will need a building permit to cut through a concrete block wall to install a door. If you have specific questions about your project or need to obtain a permit, contact your municipal building department or ask your contractor for advice.
