"Fantastic company!! Excellent customer service! I had three Anderson windows that had rotted wood at the bottoms. I was devastated since I was putting my house on the market. I was referred to Paul the owner from a mutual friend and I couldn't be more ecstatic. They ordered the sashes and Paul kept me updated on the arrival. When they arrived on Friday Paul himself came out on Saturday to install. We had an open house that next day!! He really went the extra mile for me and I will be forever grateful. From beginning to end such a great experience doing business with them!! I would highly recommend to friends and family! God bless you on a job well done!!"

"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

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.

New door knobs likely won’t have much of an effect on property value, but they can improve your home’s curb appeal and interior decor, which might lead some buyers to offer more for your home. However, in terms of personal value, adding new door knobs can be a game changer. New door knobs not only function better than older ones in most cases, but they make your home secure, and there’s a lot to be said about the peace of mind a new exterior door knob can provide.

A prehung door comes ready to install with the door already mounted in its frame, including hinges and stop molding. Everything is factory-aligned, which makes installation quicker and more precise. It’s a smart option if your current frame is damaged or uneven, or if you’re working with a new build. Instead of hanging a door slab from scratch, you fit the entire unit into the rough opening, shim it , level it, and secure it. Prehung doors are a clean, efficient way to install new doors without having to piece everything together yourself.

In most cases, a pre-hung door is a better option, not only because it’s far easier to install as a DIY project, but also because you’ll get a new frame and a new door at the same time for a more complete upgrade. Replacing a door costs more with pre-hung doors, but the additional investment is usually well worth the money. Pre-hung doors require fewer tools and less experience to install properly. With that being said, a slab door might be better if you’re on a tight budget or have a custom wall opening size that a pre-hung door won’t match.

Steel doors have a few primary disadvantages. They’re hard to customize since they can’t be cut to fit an opening; they’re cumbersome and thus difficult to install on your own; and they don’t have the same aesthetic appeal as wood doors. Finally, while they’re highly durable and secure, they are susceptible to dents, scratches, and rusting.
