"Steve, was on time, very professional, put shoe covers on , walked the inside of the house, removed screens and then started cleaning windows outside. He was very thorough, worked extra h****** a couple of windows that had not been cleaned since the home was built, which entailed scraping material off the glass and he also, had to balance on a pretty steep roof to access these. He then cleaned the inside windows, worked top to bottom and was very careful when moving furniture. Overall, took his time and did the job right!"

Window Cleaning FAQs, answered by experts

Professionals use HEPA vacuums, industrial-strength cleaners, and microfiber cloths for effective cleaning without damaging surfaces.

Distilled white vinegar removes stickers from glass by breaking down the adhesive with its acidic qualities. You can apply the vinegar to the area with a sponge or cleaning cloth. Let it sit for 10 to 20 minutes, and then scrape the area with a plastic scraper or the edge of a credit card.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

Yes, professional window cleaning is worth the investment. Regular deep cleanings help keep your windows looking new, extend their lifespan, and boost your home's curb appeal. By removing dirt, dust, and other debris, you can reduce the risk of damage and accelerated wear to window frames and components. It also improves your home’s energy efficiency by keeping insulation and weatherstripping in good working order, potentially lowering your energy bills. Furthermore, annual or bi-annual cleanings can help identify problems like leaks or cracks early, before they escalate into expensive water damage. You can often recuperate the cost of cleaning through energy savings and by avoiding premature window replacement.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.
