Why Pure Water Window Cleaning Outperforms Traditional Methods
The Pure Water Difference
Most window washing leaves behind mineral deposits, soap residue, and streaks. We don’t use soap at all. Guardian Exterior Services uses a professional Pure Water System — the industry gold standard since 1957 — to deliver genuinely clean, spot-free windows every time.

Here’s how it works:
Tap water contains Total Dissolved Solids (TDS) — minerals, chlorine, and contaminants that leave spots and film on glass. Our system runs your tap water through a filtration process including deionization (DI) filters, removing virtually all dissolved solids. What comes out is ultra-pure water that acts like a magnet, pulling dirt off glass and rinsing away clean without leaving anything behind.
When pure water dries, there’s nothing left to see. That means no spots, no streaks, no residue.
Safe, Chemical-Free Window Cleaning for Roanoke Homes & Smith Mountain Lake Properties
Our water-fed poles let us clean windows from the ground up to three stories high — no ladders leaning against your siding or gutters, no risk of roof or trim damage. Because we use zero soaps or chemicals, there’s no runoff to harm your landscaping, garden beds, or — especially important for Smith Mountain Lake area homeowners — the lake itself.
- Every exterior window cleaning includes:
- Ground-level to 3rd-story reach with no ladder against your home.
- Filtration through our DI pure water system
- Scrubbing with a GLIDE brush to agitate and loosen dirt, pollen, and oxidation
- Pure water rinse that dries completely clear
- Screen removal and replacement (may be additional service fee)
Who This Is For
Our exterior window washing is ideal for homeowners and property managers dealing with pollen buildup, hard water spots, construction dust, road film, or simply windows that haven’t been cleaned in too long. It’s also an excellent add-on to our House Bath soft wash service — clean windows and clean siding together make a dramatic visual difference.
When is the best time to have my exterior windows cleaned?
The perfect time for exterior window cleaning is right after a house wash. The solutions we use to soft wash your home are gentle and won’t leave your windows in worse shape — but without a final rinse from our deionized pure water system, the glass simply won’t reach its full potential. Tap water leaves behind dissolved minerals that dry as spots and film, while our filtered water pulls away any remaining residue and dries completely clear. Bundling both services in one visit is the smartest way to get the most out of each.
