"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!"

"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

Glass block windows are energy-efficient because they are much thicker than traditional glass panes, making them better insulators. They are sealed airtight, which prevents drafts and stops warm or cool air from escaping, helping to save money on heating and cooling bills. Unlike traditional windows that can be opened and closed, sealed glass block windows eliminate the potential for air leaks. For proven efficiency, look for options that are Energy Star rated. The cost for energy-efficient glass block windows is typically around $400 per window, which may be higher than standard windows.

The amount of time window lintels last is based on the environment they’re installed in and the material that’s installed. For example, a steel lintel installed in a temperate climate will always last longer than a wooden or brick lintel installed in an area with tons of rain, snow, and wind. No matter which material you choose or where you live, proper maintenance will ensure your lintels last as long as possible.

In addition to protecting your home from costly storm damage, storm windows increase your home's value if you live in an area that’s prone to severe weather. Storm windows offer about an 80% return on investment (ROI). Therefore, if you install $10,000 worth of storm windows, you can expect to get around $8,000 back if you sell your home within a few years of installation. Additionally, highly hurricane-prone areas, like the Florida coast, offer even higher returns, with ROIs on storm windows reaching up to 86%.

Yes, storm windows should be tempered. According to the International Association of Certified Home Inspectors, tempered glass is stronger and can withstand temperatures higher than laminated glass. Tempered glass is important for storm windows because it protects against outside elements and household accidents by not producing sharp, jagged pieces when it breaks or shatters.

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.
