"Hyperion came out and gave a quote for the window replacements. Explained the work that would be done and how it would be done. Showed up on time to do the work and did a fantastic job. So rare now days that someone actually says what they are going to do, does it well and professionally."

"Alex Faires is the nicest guy. Even before he came out to give me a bid on the work, he spoke with my insurance company about the siding on my house, which no other contractor would do unless I hired them. That alone got him the job. However, his bid came in way below the other estimates I received, which was a bonus in my book. He was upfront, helpful, and patient with me. He took the time to explain anything I didn't understand and kept me informed from start to finish. His team and crew were awesome as well. They had no problem installing light fixtures and address numbers; and they took down a metal awning that was an embarrassment to the neighborhood. I cannot recommend Alex, his team and H&F enough. They will be my go-to for any work related to the exterior of my house."

Window Door Contractors questions, answered by experts

Windows and doors can be fitted with specialized seals and acoustic glass options for better noise reduction.

Security doors are not limited to standard sizes, and you can customize them to fit your needs and entryway dimensions. That's one of the fantastic things about security doors—they can be tailored to match your home. Keep in mind that a custom-sized security door will likely cost more than a standard size. 

Fire doors are constructed to have certain resistance levels regarding fire. A traditional door can typically resist fire for less than one minute, whereas fire doors can resist it for 30 to 120 minutes, depending on the fire door rating. Fire doors give you and your family a better chance of safely escaping during a fire than standard doors. 

Look at the door from the outside, or the key side. If the hinges are on the left side of the door, it’s a left-hand swing. If the hinges are on the right side of the door, it’s a right-hand swing. You can also think of it as which hand you would most likely use to open the door from the outside when considering whether it’s a right-hand vs. left-hand door.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door.
