"I hired Mountain Top to do several repairs and updating to my home and they were great. Jared was great to work with, is a very good listener and got the job done. They painted my outdoor wraparound deck, my garage, added a brand new updated flagstone entryway and did some landscaping work. They were efficient, easy to work with and their work was excellent. I would highly recommend Mountain Top."

Security Doors questions, answered by experts

Pocket doors fell out of popularity due to previous functionality issues and the raised tracks. But design and function have improved significantly in recent years, giving pocket doors a resurgence. They can be the perfect choice for a small space or to close off an adjoining room, such as a home office or dining room.

You don’t need to shim both sides of a door, but it’s always a good idea. Wall framing is rarely perfectly plumb, and shims let you make minor adjustments to get your door perfectly level and plumb. This will ensure the door swings open and closes smoothly. You can also use shims on both sides of the door you’re installing or adjusting to center it in the wall opening.

Spacing a door is tricky since you need to leave enough of a gap for the door to move freely and not get stuck when the slab and frame contract and expand in dry and humid conditions. The ideal gap between a doorframe and slab is 1/8 of an inch. If the gap is any larger, the door will feel drafty. But if the gap is any smaller, the slab can get stuck due to weather changes.

The most common rough opening for a sliding glass door is 60 inches to 72 inches by 80 inches. A rough opening is the unframed space where your door will go.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.
