"Very well!! Brian did a great job installing 4 custom blinds in my home. Brian measured the rest of our widows and offered sound advice on how to accurately order blinds for them. I highly recommend Brian for his handyman services."

"I went through numerous window companies and received many quotes and Good Fellows Window Corporation was by far the best in not only price but professionalism. Gary Greene, the owner, is professional, friendly and very personable. His prices were very reasonable...he was honest and not pushy at all. he was available at all times throughout the whole process from the estimate to installation. His crew was AMAZING! they were on time, clean, meticulous about the installation of each window and door. they took their time and made sure it was done accurately. they did not leave a speck of debris in or outside my home. I would completely recommend this company if you need new windows or patio doors installed. I had a stress free experience all due to Gary and believe me I was initially stressed out after meeting with so many companies and getting some crazy quotes. I'm happy I hired them and the job is complete and I am TOTALLY HAPPY...thanks again Gary and Crew"

"Things started well right from the start.  An email was sent to me which provided me with a photo of the salesperson who would be coming so that I would be sure I was dealing with the right people.  The price on the garage door was higher than that provided by other vendors but the quality of the door was higher and the job was going to entail replacing all of the hardware that had been in place.  It made sense since some of the hardware was in-place since 1979 and it was time to go. None of the other vendors were going to do this. 
The gutters were installed by a different team - and on a different date - from the garage door team.  Both of them were polite, efficient and prompt. 
The only thing I would have wished is that I would have been able to make one call and be able to get information on both projects.  The way DiGiorgi is structured, each area is separate and you need to call each area individually.

"Absolutely a better experience than we anticipated. ProEdge is a responsive company, and they know the value of customer service. We will be reaching back out to have them complete our window projects once our addition is completed, and to replace exterior doors."

"Let me just prefix this by saying weâ ve had a few bad experiences working with contractors in the past. We had our porch done recently by a separate contractor, and dealing with that company was a nightmare. Material left out, never showing up to the job on the day they said, shoddy work ectâ ¦.. however, THIS was the opposite of that experience. We needed a cement slab poured. First off They were able to work the job right away basically, they were there when they said they would be there, on time. They worked quickly, and cleaned up the job and materials once it was completed. The slab once it was finished came out better than I had expected. Also the main contractor running the job was very communicative. So all in all I would 100% call them back. By far one of the better contractors weâ ve worked with over the years"

"Ordered a new storm door as the wind blew it and it would not close anymore. They brought a new one and took the old one off and when they put the new one there. It was too small. They had ordered it wrong so they put my old one back on and it closes again so I canceled the new door."

Window Door Contractors FAQs, answered by experts

Whether you should repair or replace a screen door depends on the type and extent of the damage. It is easy and economical to repair a small tear in the mesh using a widely available DIY patch kit. However, if there are large tears, multiple damaged spots, or if the screen is made of a specialized material, replacing the entire screen mesh might be a better long-term investment for a tidier appearance. You should also consider the condition of the frame; if the frame itself is damaged, it's likely time to replace the entire door. Other factors to weigh include whether you want a new style or need a more durable door.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

No, it’s not safe to leave a doggy door open. It might be more convenient, especially at night when you just want to lay in bed. However, when you leave it open, it increases the chance of other critters getting in without your knowledge. Also, it leaves your pup unsupervised for hours at a time.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.

If you’re not keen on using a traditional doggie door, there are some alternatives. One popular option is a solid, insulated door that you can lock when you’re out of the home for added security. You can also opt for a doggie screen, which you can lift and lower to allow your pooch access to the outdoors. These are a bit more convenient to use than a regular exterior door, although security could be an issue. You can also install a screen door with a small opening for your pup to prevent bugs from coming inside as your dog exits.
