"Tom did a fantastic job with pressure washing our large vinyl fence (285 linear feet) on both sides and the mildew on the north side of our house. He was a super nice guy, got here on time and did a thorough cleaning for a reasonable price. Our fence and house looks great! We would highly recommend!"

"We have used H20tek in the past and our 3 story house had some facia blow off and they came in and attached the facia for us and cleaned gutters while they were there. Price was reasonable and I didn't even get a quote / trusted H20 and they were there quick and charged a reasonable price. I definitely would recommend them in the future and they are going to do some pressure washing on our patio as well. They also noted that the house probably doesn't need it again as we did recently, so they have no interest in selling you for things you don't need, which is also appreciated. Again, highly recommend and the owner Jonathan is very easy to work with for sure!"

"Wow what an excellent crew Gray’s landscaping has. Very professional and gets the job done. This company deep cleaned, deodorized and sanitized my carpets actually brought them back to life. Also my lawn looks grrreat. If I can give 10 stars I would."

Window Cleaning FAQs, answered by experts

Yes, many professionals use biodegradable detergents and water-efficient cleaning techniques to minimize environmental impact.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

Whether you tip before or after a carpet cleaning depends on when you’re available. If you’re home when they finish up, you can give them their tip after. However, if you need to leave before they’re done or if you won’t be home at all, you can prepare the tip beforehand and leave it for them in an envelope.

In most cases, you should get your windows cleaned one to two times annually, although you might want to complete this task more often if you live in an area with heavy pollen or heavy rain or snowfall that soils your windows. It’s also a good idea to hire a professional window cleaning service if you’re listing your property, as sparkling windows will make a big difference in terms of curb appeal and, potentially, your home’s value.

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.
