"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."

Windows questions, answered by experts

Windows may need to be replaced after a hurricane if they’re severely damaged. For example, if you have windows with blown-out glass and a cracked frame, they will need to be replaced. It’s a similar story if you have windows with noticeable water damage. However, if your window pane has small cracks but the frame is still in good condition, you may be able to repair the window.

The material around a window is simply called the window frame, but the individual pieces also have different names. The top portion of the frame is called the head, the side pieces are called jambs, and the bottom portion is called the sill. If you have multiple windows next to each other, you’ll also have a mullion, which is the frame piece that separates the individual windows. Windows stacked on top of each other are separated by a horizontal frame piece, which is called a transom.

There are a few reasons your crank windows might not close. First, determine if your window crank is working properly and opening and closing the window when you turn it. If it’s not, the crank may need replacing, cleaning, or lubricating. Another reason your windows aren’t closing could be dirt and debris in the window hinges or sash. Finally, make sure your window lock operator is set in the unlocked position and isn’t blocking the window from fully closing. If you’re still having trouble closing your window, it may be worth consulting a local window contractor.

Window replacement is typically always worth the cost, both from a money-saving standpoint and a comfort standpoint. If your windows are older and significantly damaged, a window replacement can actually save you money in the long term by improving energy efficiency. If your windows aren’t up to code, you may not really have a choice. 

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.
