"

From sales to installation, the process was exceptionally smoothly and everything happened as was originally scheduled and promised. Communication was excellent, advice from the estimator was spot-on, the quality of the doors even better than what we expected and the installation was EXPERT. The doors look fabulous, work perfectly, and the installer did a much better job than what we could have done ourselves. We are so glad that we decided to outsource this service and we highly recommend this company.

Doors FAQs, answered by experts

On average, sliding glass patio doors can last between 20 and 30 years. Their actual lifespan depends on several factors, including proper installation, frequency of use, and regular maintenance of the sliding components. While this is the typical range, minor problems and the need for occasional repairs or part replacements can still occur. Addressing issues as soon as they arise and performing regular maintenance will help extend the door's life. If the door is older and requires frequent or significant repairs, it may be more cost-effective to replace the entire unit.

When choosing a door for the space between your garage and house, steel is your best bet for fire safety. While wood—and sometimes glass—doors are common, they have lower fire-ratings. Fire-rated steel doors can withstand flames for up to three hours—double what wood can manage (90 minutes). Glass, while non-combustible, can crack under extreme heat. Steel may cost more, but it also offers the best protection. Steel isn’t the most aesthetically pleasing choice, but as long as your door meets the International Residential Code (IRC) standards, it’ll do its job in protecting your family and home.

The vast majority of hinges are symmetrical, and either side of the hinge can go on the door or the frame. Occasionally, you'll find a hinge specifically made for right or left-handed doors with different attachment hardware or larger plates on one side. In most cases, the large side of the hinge goes on the frame.

It is possible to install hinges backward, so be careful when placing them. Position the hinge so that the hinge pin faces the direction the door will swing. For example, if you're standing on the side the door will open into, the pin should be visible. Be extra careful when installing exterior doors, as placing the hinges on the outside for an outward-facing door makes your home much easier to break into.

You should generally cut between 1/8-inch and 1 inch when planing a door. If you cut off more than that, you risk damaging the door. Planing too much from the bottom of your door can cause noticeable gaps, so it’s always better to start with as thin of a section as possible and work in thin layers until your door no longer sticks.
