"CFoam did an incredible job on all the windows around my house. They were spotless — no streaks, no water marks, nothing. I could barely tell the glass was even there. Worth every penny."

"I've tried other window cleaners before and always ended up with streaks or missed spots. CFoam was different from the start — super professional, on time, and my windows honestly look brand new. Signed up for the monthly membership immediately."

"Had CFoam come out for exterior cleaning and they also cleaned the screens and sills without even being asked. Just incredibly thorough. My house looks like it had a total facelift. Highly recommend."

Exterior Window Cleaning at CFoam

Our Comprehensive Step-Cleaning Process

At CFoam, we don't just wash windows — we restore them. Our exterior window cleaning begins with a detailed inspection of each pane, identifying problem areas like hard water deposits, oxidation rings, construction residue, and dirt buildup before a single tool touches the glass.

From there, we work through our structured 4-step process — scrubbing, squeegeeing, detailing, and sealing. Every window leaves our hands streak-free, spotless, and protected against future buildup.

Recurring Cleaning Services

Clean windows don't stay clean forever — especially in South Carolina, where pollen, humidity, and storm season take a toll year-round. That's why our recurring membership plans exist.

Whether you choose monthly, quarterly, or biannual service, you'll always have a scheduled cleaning on the calendar — no chasing quotes, no forgotten windows. Members get priority scheduling so your home is always first in line.

Recurring clients also receive complimentary hard water removal treatments — a service that normally runs extra — included with every visit. Keeping your windows clean on a schedule is the single best thing you can do for your home's curb appeal and long-term glass health.

Spotless Sill & Frame Service

The glass is only half the story. Dirty window sills, grimy frames, and clogged tracks make even clean glass look unfinished. CFoam treats every frame and sill with the same attention we give to the pane itself.

We hand-detail every edge, corner, and track — removing built-up grime, insect debris, mold, and oxidation from aluminum and vinyl frames alike. The result is a complete, finished look that elevates the entire face of your home, not just the glass.

Why Choose CFoam?

There are plenty of window cleaners out there. Here's what makes CFoam different:

Zero Streak Guarantee

If you find a streak after we leave, call us. We'll be back within 48 hours to make it right — no questions, no charge.

Locally Owned & Invested

CFoam is an upstate South Carolina business. When you hire us, you're supporting a local team that genuinely cares about the quality of work in your community.

Professional-Grade Solutions Only

We never use household glass cleaners or diluted products. Every job uses commercial-grade, glass-safe solutions that cut through the toughest grime without damaging seals or frames.

FAQs About Exterior
Window Cleaning

For most homes in upstate South Carolina, we recommend exterior window cleaning every 1–3 months. Pollen season in spring can coat windows within days, and summer humidity combined with storms leaves residue quickly. If you notice buildup, reduced natural light, or visible streaks from inside, it's time to book. Our membership plans make regular cleaning simple and affordable.

Yes. Hard water stains — caused by mineral deposits from sprinklers, rain runoff, or well water — can etch into glass over time and are notoriously difficult to remove. CFoam uses professional-grade hard water removal treatments that break down calcium and magnesium deposits without scratching the glass. Members receive this treatment free with every cleaning visit.

Absolutely. All of the cleaning solutions we use are professionally formulated and biodegradable. We take care to protect surrounding landscaping, and our technicians are trained to rinse surfaces thoroughly after cleaning. You don't need to move plants or keep pets inside — though we'd love to meet them.

Yes — standard single and double-hung windows, large picture windows, sliding glass doors, skylights, transoms, and multi-story windows. For two-story homes and above, we use extension equipment to reach upper windows safely without ladders on your property. If you have a specific window type or configuration you're unsure about, just ask us when you get a quote.

Yes, absolutely. While our membership plans offer the best value and ongoing results, we're happy to schedule one-time exterior window cleanings for any home. Contact us for a free quote — we'll assess your windows, give you a straightforward price, and get you on the calendar. Many customers start with a one-time service and switch to a membership after seeing the results.
