Glass Care

Proper care of your window and door glass is important to gain the maximum effectiveness of insulating, low-e or reflective glass. The following actions may damage the glass surface or the insulating glass seal and SHOULD NOT be taken:

  • DO NOT use of petroleum-based cleaners or caustic chemicals on the glass;
  • DO NOT use of a razor blade, abrasive pad or putty knife to clean the glass; and
  • DO NOT use of a high-pressure spray nozzle when rinsing the glass after washing.

Instead, you should clean glass with a high quality dish soap and water, rinse completely with clean water, and wipe dry with a soft cloth to avoid water spots.

Screen Care

When washing screens, you should first remove the screen, then wash on a clean, flat surface with a mild soap and water solution using a soft brush. Finally, you should rinse, dry and reinstall the screens.

Mold and Condensation

Water condensation can occur on your window and door interior surfaces if certain conditions exist. The condensation may be a warning to you that excessive moisture exists in your home, and this moisture may facilitate mold growth. This is because condensation on interior window surfaces results from higher moisture content in the air, contacting lower temperature surfaces on the glass or frames. The higher your home’s interior humidity and the lower the outside air temperature, the more condensation may occur.

The following actions SHOULD BE taken to limit or prevent mold and condensation:

  • Checking all window sashes for smooth and regular operation, and increasing interior home ventilation and air exchange devices if needed;
  • Using your exhaust fans, particularly when showering or bathing;
  • Installing a dehumidifier or using ceiling fans to improve air circulation; and
  • Opening windows and doors when practical to allow interior moisture to escape.

Drainage Systems

Window and doors use a simple drainage system designed in the frame itself. Water drainage pathways designed in the frame should be kept clean and clear of any obstructions to operate effectively. It is normal for water to accumulate in the sill or track area during a period of wind-driven rain.

The drainage system is designed to allow the water to train to the outside as water build-up, or outside wind pressure subsides. A clogged drainage system could prevent excess water from draining. Over time standing water can damage your window or door and lead to structural damage from mold, mildew and wood rot if water enters the wall cavities of the window or door.  Accordingly, the following actions SHOULD BE taken:

  • Keep all sill or track surfaces clear of dirt and debris.
  • Ensure that exterior drainage holes are clear of debris, stucco, sand or other obstruction,
  • Regularly inspect the exterior perimeter of your window and door frames for any cracks, or cracks in the adjacent siding material that can cause moisture to penetrate (if a crack appears, seal with a high quality sealant product, according to the sealant product manufacturers’ instructions)

Smooth Operation

The following actions SHOULD BE taken to ensure a smoothly operating product:

  • Regularly lubricate the moving parts of windows and door hardware, using a spray silicone product and being careful not to apply excessive amounts. Wipe up any drips or spills. (In salt-air environments, monthly cleaning and lubrication may be necessary to preserve function.
  • Inspect weather stripping on operable windows and doors to ensure it seals evenly when clo
  • Keep the track area clean, frequently vacuuming to clear any accumulated dirt and dust.
  • Adjust sliding door rollers for proper height clearances (door rollers are adjustable with a screwdriver through access holes in all four corners, in either the end or side of the sliding panel, located near the bottom of the panel).
  • Adjust rolling screen doors to slide smoothly (use a screwdriver, in all four comers, to make adjustments),
  • Check on the sliding door lock struck placement if you adjust the door rollers (adjustment is made by loosening screw fasteners, moving strike plate, and tightening).

David and crew were great to work with. My install was originally scheduled for 2 days but they were able to do the whole house in one day. I love my new windows, I can already feel the difference in temperature in my house. The windows look great and were more affordable than other companies. - 4/12/2026

Can’t recommend Advanced enough. Good quality windows that are in built in house and made to last. I already can tell the difference in my energy efficiency in my home. Install was quick and clean. Highly recommend! - 4/10/2026

Had a good experience with the company, very easy and painless. Of course it was a bit pricey but they were cheaper than other companies I had looked at. Was able to get financing with 0 interest which was a huge plus. The guys who came to install were professional and were done in about 6 hours. The windows look great and are high quality. I feel like they will last a long time and will update my review over time. - 4/10/2026

Just wanted to give a big thank you to Kevin and Anthony for their time on installing new windows on our home.We have an older home that has the original windows on the home and with that can come complications upon window removals, they were efficient and effective. Extremely respectful and kind. They talked me through the steps they were taking and why. Very friendly guys who did the job in such a great way! We are so happy with our new windows, and I was amazed at how much of a difference it has made and it’s only been a few hours since they have left!From beginning to end this process has been great and we cannot wait to use them again when we end up replacing the last few windows on our home!Thank you again! - 4/10/2026

I'm very impressed with Advanced Windows! It's a company that 100% stands behind its warranty. Advanced Windows replaced all the windows in my house thirteen years ago. Since then, a few parts have worn out or needed servicing. Each time I called, Advanced Windows promptly came out and corrected the issue with a smile. Today, Gary came and replaced the latch on my sliding glass door. This company is a class act! - 4/09/2026
