The Central Texas Difference
Round Rock's climate is tough on windows. Cedar season coats glass with a yellow film. Summer storms leave mineral deposits from hard water. High-traffic roads like I-35 and 45 create dust and exhaust buildup that sticks to exterior glass. Our purified water system and professional technique cut through all of it — leaving glass that looks clear, clean, and treated right.

Central Texas Grime Meets Its Match
Round Rock's exterior windows face a unique combination of challenges: heavy spring cedar and oak pollen, mineral-rich irrigation overspray, I-35 road grime, and the kind of relentless UV exposure that bakes everything in place. Standard cleaning methods simply don't get it all off.
Heritage uses purified deionized water fed through professional-grade water-fed poles — the same technology commercial high-rise cleaners use — to deliver a truly spotless exterior clean that lasts. No minerals in the water means no spotting after it dries.
Frequently Asked Questions
What makes exterior window cleaning different from regular cleaning?
Exterior windows face pollen, road grime, sprinkler overspray, hard water deposits, and UV weathering that interior glass simply doesn't. They require specialized equipment — like water-fed purified water poles and mineral deposit treatments — to restore them to true clarity. A bucket and squeegee alone won't cut it for seriously fouled exterior glass in Central Texas.
How often should exterior windows be cleaned in Round Rock?
We recommend exterior window cleaning 2–4 times per year in Round Rock. Spring is critical after cedar and oak pollen season. Fall is ideal before the holidays. Homeowners with irrigation systems hitting their windows may benefit from more frequent service due to hard water buildup.
Can you remove hard water stains from exterior windows?
Absolutely. Hard water staining from Round Rock's mineral-heavy irrigation water is one of the most common issues we deal with. We use specialized mineral removal treatments to safely dissolve calcium and lime deposits without scratching or etching the glass.
Do you clean exterior window screens as part of the service?
Yes. Dirty screens block light even after the glass is clean. We remove, hand-wash, and re-hang exterior screens as part of our full exterior cleaning service. We also wipe down frames and sills so the entire window looks sharp.
What is your 7-Day Rain Guarantee?
Simple: if rain causes spotting on your exterior windows within 7 days of your Heritage cleaning, we come back and touch them up at no charge. We stand behind our work because we know Texas weather doesn't wait for anyone.
Is your exterior cleaning process safe for my landscaping and pets?
Completely safe. We use 100% purified deionized water for the main clean — no soap, no chemicals — and any pre-treatment solutions we apply are biodegradable and non-toxic. Your plants, pets, and lawn will not be harmed.
