"I am still waiting for the return of my deposit as it has been a week since I put this review on hold after putting in the notice that day 24 June of cancellation by email and next day mail. As I have said before I am a disabled Vet, Senior citizen with health problems. I have copies of the emails that I sent on the days of 06/24/2023 and by next day Mail on the 27th notarized copies of the cancellation. Tried calling but went to voice mail. No work has been done so a rating cannot be done on the work, only the price. This job was way overpriced and never got the chance to compare. The salesman was a good person but I have my family doing it for thousands less."

"The company goes out of their way to ignore reviewing HOA policy. They installed doors that were not up to code based on HOA policy. More concerning for a small $1,000 balance of a $5,000 job, they threatened while saying good luck to me....to file a mechanics lien on my $2,300,000 paid off house. IT IS AGAINST STATE LAW TO FILE A MECHANICS LIEN AGAINST A RESIDENCE UNLESS THE VALUE OF THE JOB INCREASES THE RESIDENCES VALUE BY 15% OR MORE. They are threatening and go around every legal corner to get what they want including their bogus sales pitches."

Windows questions, answered by experts

When specifying window sizes, manufacturers use a standard four-digit code system. The first two numbers represent window width, and the last two represent window height. For example, a window with a code of 2917 has dimensions of 2 feet, 9 inches wide by 1 foot, 7 inches high. Windows with even dimensions include zeros as placeholders. For example, a window that is 5 feet wide by 2 feet high would have a code of 5020.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

High winds can be harmful to casement windows and all types of windows. Because casement windows can swing outward, high winds could slam the window against the side of the house, bend the hinges, or even rip the window off of the hinges. If you hear some strong gusts outside, it’s best to pull the casement windows shut until it all blows over.

Clean the glass regularly, inspect the frame and well for debris, and ensure the cover or well drains properly.
