Window Door Contractors questions, answered by experts

Many doorways feature two door jambs. These are installed on both sides of a doorway to prevent the door from swinging too far. Door jambs usually stop the door at 180 degrees when closed.  A doorway floor transition sits between the door jambs on the floor, helping to create a safer and more aesthetically pleasing transition from one flooring type to the next. 

When it comes to painting hollow core doors, the top recommended paints to use are semi gloss or satin finish. If you do paint hollow core doors, be sure to gently sand the doors and use a paint primer to ensure the paint sticks.

When choosing between an inward- or outward-swinging door, there’s no right answer. Inward-swinging doors are great for avoiding debris and keeping hinges inside for added security. Alternatively, outward-swinging doors can give you more space inside your home, and some homeowners feel they’re harder to force open. Ultimately, neither is “better,” but a door expert can help you figure out which fits your needs.

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.

Butterfly hinges are one of the most common types of hinges and you can use them all over your home. Though they’re common on doors, cabinets, and shutters, you can even find them on decor, like jewelry boxes, music boxes, and trunks. Doors may have basic butterfly hinges, while the hinges on cabinets and decor may be more ornate.
