"F and A did a fantastic job cleaning our windows and doors! The communication was great, they arrived on time and cleaned every glass surface, sills, and screens until they looked almost new. It was wonderful to walk into the house and see the sun and plants through sparkling clean windows. We will hire F and A to clean our windows every spring!"

"We want to thank Dominik for his expertise and advice when choosing our windows. We needed 12 original windows replaced, and he helped us choose windows that give the house a clean, refreshing look. He was very professional and explained the energy benefits we should expect to see."

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"We have once again reached out to Joe Kim at J & K Home Improvements when we had a new project planned. We were completely satisfied when we replaced our siding and roof with Joe. Now Joe and his professional crew have replaced all our windows . There are never surprises or additions from when the job is quoted. Once again we are totally satisfied and delighted with their work!! It has been a stress free experience each and every time."

Windows questions, answered by experts

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.

In some cases, you might need a permit for a window replacement, which is hard to get if you’re not a professional contractor. You should probably just hire a window replacement company in the first place because the job is complicated and can be dangerous for the average DIYer. You may not even save any money doing it yourself because contractors purchase materials wholesale.

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.

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.

Visibility through tinted house windows or privacy film depends on the lighting. During the day, the tint or film typically prevents people from seeing inside. However, at night, if you have lights on inside your home, the interior will be brighter than the outside, which allows people to see in. You can choose from various shades of privacy film, from lighter to darker, to optimize the level of privacy you want.
