"My handyman recommended Aldefer glass as I need to replace the glass in my shower since it was an unusual size. When they were here to measure they mentioned they also could replace my kitchen windows. I was excited, one stop shopping. Well it’s two different departments... They had to come back and remeasure the windows, Another 2 week wait. They would not order until I gave them a 50% deposit (which is OK). They told me it would be 2 wks to get the glass then approx 2 weeks to install. I had to call numerous times to see if windows had arrived and schedule install. Bottomline my 4 wk anticipated install was over 2 months, then the middle glass in the tempered shower shattered during install ( 2 phone calls and 4 Additional weeks later shower complete). Kitchen windows still not right. Flys keep getting stuck between window and screen so I can’t open 2 of 6 windows in my kitchen. Terrible customer service. I have several more windows that I need to replace, they will not get my business. Truly awful experience."

"At first I rated them a 5 but they had me put in a review before the job was even completed. They used old tarp from previous jobs. There were debris all over my bedding and furniture from the old plastic tarp. If they needed new tarp I would supply them. Who knows what the previous projects had in their homes. I didn't notice till after they left. Yes, you definitely will need to vacuum. Which I expected, but not having to wash all bedding and vacuum furniture. The windows look good, but it's so much cleaning afterwards. So when they say you'll never notice they were there. Was not true at all. One of my bushes in the front were also damaged and trampled on."

Windows questions, answered by experts

Yes, including the frame instead of just referring to the glass opening for window dimensions is the standard. However, some manufacturers may refer to the rough opening instead of the framed opening when listing sizes. Always confirm which measurement a manufacturer is using before ordering windows.

Garden windows can add value to your home and are an attractive feature for potential homebuyers. These windows add a custom look to your home and usable shelf space for homeowners with a green thumb. You’ll likely recoup your investment when it comes time to sell.

When comparing impact windows vs. hurricane shutters, it’s important to consider the protection and installation details to determine the right choice for you. For constant protection against storms and flying debris, impact windows are a better option than hurricane shutters, especially if you don’t want to install shutters that will change the look of your house. However, impact windows are more costly than hurricane shutters. If you want a budget-friendly option that’s still protective against storms, hurricane shutters are a solid option. 

DIY is possible with the proper tools. Professional installation ensures a proper seal and energy efficiency.

Removing a window isn’t a very long process. Depending on several factors, it can take anywhere from 20 minutes to upwards of an hour. The size of the window greatly impacts the time it takes to replace it. Accessibility is another big component. If it’s hard to reach the window or reaching it is dangerous, anticipate it taking longer. 

Lastly, if the old window is in poor condition, it could take longer to remove it safely—especially if the frame has wood rot and is structurally unsound.
