"Rudy and his team were great! Quoted me price, some windows required additional work but kept the agreed upon price. Rudy and the team arrived right on time and finished exactly when they estimated. Very nice and respectful crew, always important with kids in the house. Windows look like new! Highly recommend!"

Window Cleaning questions, answered by experts

Finding a quality professional window cleaning service is much like finding any other vetted home pro: You should ask friends and family members who you trust for recommendations for window washers in your area and check online ratings. Reading a company’s reviews will give you a lot of insight into the service you can expect. Then, check their credentials and contact them to get a quote. Be sure to ask questions about their process and the products they use to get your windows to shine.

The best homemade cleaning solution for windows is one gallon of warm, distilled or bottled water mixed with five to ten drops of liquid dish soap. This is what professional window cleaners typically use when they make their cleaning solutions. Using bottled or distilled water will help avoid hard water stains after cleaning, and the soap will cut through grease, smudges, and debris on your glass.

Yes, professional window cleaners will clean the surface of the glass on both the inside and the outside. They will usually clean the tracks for your windows, check and clean the weatherstripping, and even disassemble parts of your window, if necessary, to clean and lubricate interior components and moving parts.

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.

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.
