"Roofing its something no home owner ever wants to do, but most have to go through. I won't even lie I wasn't even planning on getting a new roof, but Dale Knocked on my door and thats where the process started. My roof did go through insurance & aside from signing paper work/paying my deductible A1 handled everything. Obviously specific details from the insurance goes to you and then given to A1. Its not a short process and there is paperwork you have to sign, but all In all it did take me about 4 to 5 months where the process was started to roof replacement. Dale handled interactions with showing my the conditions of my roof and how to go about getting it put through the insurance. The only hiccup was that I have solar panels and I did feel like they where taken down to early (almost 5 months off), but I made my concerns known and one of the Managers called me and credited me $500 bucks (100 per month) that the panels where off. They did tell me setbacks in productions and things happen, but made me happy by giving me this credit. Didn't fight me on it, and didn't make me feel like I was just an insurance check on the other end. You can trust A1 home improvement with your home. I would like to thank Dale for his work & all the others that helped me throughout one of the most stressful process there can be for a house."

Window Door Contractors questions, answered by experts

You can install many types of interior doors without a frame as long as the door is prehung or there is already an existing door in the opening. If the opening has never had a door installed, you will need to install a frame with the door. Consult a professional door installer to inspect the opening to determine whether or not it’s possible to place a door there without a frame.

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.

The lock block will either be built-in on the side of the door or run from the top to the bottom. Usually, there is a marking that indicates its location. You can also tap the door with the back of a screwdriver to find the lock block like you would find a stud in a wall.

It’s certainly easier to paint a door while it’s still on its hinges, but you may get better results if you remove it from the hinges. Painting a door off the hinges allows you to work on it horizontally, making prep work easier, reducing drips, and allowing undisturbed drying time.

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.
