New York winters are hard on everything - and your windows are no exception. Road salt spray, exhaust fumes, heavy snowfall, and bitter cold leave glass looking grey and streaky faster than most people expect. By the time spring arrives, the film that's built up over winter isn't something a quick wipe with a cloth is going to fix.
In winter, the real culprit is road salt. It gets picked up by passing traffic, carried on the wind, and deposits itself across every window that faces the street. It doesn't just look dirty - salt is corrosive, and left on glass long enough, it starts to etch into the surface.
Urban grime from traffic fumes coats city-facing windows in a thin, greasy film that standard cleaning often just smears around. Spring brings pollen that sticks to the residue left by winter. Then summer humidity causes condensation to form and dry repeatedly, leaving water marks and smearing. By the time autumn arrives, your windows have been through a full assault and it shows.
Wind-carried salt etches into glass all winter.
Traffic fumes leave a greasy film on city glass.
Sticks to winter residue and clouds the glass.
Repeated freeze-dry cycles leave water staining.
Standard cleaning products freeze, streak, and fail in cold temperatures. We use cold-weather safe solutions that stay effective through the winter months, so you're not waiting until May to get clean windows. Our pure water system filters out minerals before the water touches your glass - which means it dries spotless, even in lower temperatures.
We also know how to work on older New York buildings. Brownstone frames, aged timber sills, painted masonry - we adjust our approach to the material. No harsh chemicals that could lift paint or damage aged stone. The result is a thorough clean that looks right and doesn't cause any problems for your property.
No guesswork, no rushed jobs. Here's what we do from start to finish.
We walk the property first - checking every window for damage, salt buildup, access issues, or anything that needs flagging before we start.
Cobwebs, loose dirt, dried salt deposits, and debris are cleared from frames, sills, and glass before any liquid is applied.
Any salt residue or mineral deposits are treated with specialist solution before the main clean, giving it time to break down the buildup.
We wash the glass with our purified water system. No minerals in the water means no spots when it dries - just clean, clear glass.
Every pane gets squeegeed and hand-detailed around the edges. Frames, tracks, and sills are wiped down at the same time.
We inspect every window from both sides. We don't pack up until everything looks right - that's the guarantee.
The same process on every property - no cutting corners, no matter how big or small the job.
No guessing what you're getting. Here's the full list.
Both sides cleaned to a streak-free finish - inside and out.
Salt, grime, and winter residue removed from all exterior panes.
Screens removed, washed, rinsed, and put back.
All tracks and frames cleared of dirt, salt, and winter debris.
Window sills wiped clean - inside and out.
Specialist treatment applied to salt and mineral deposits.
Every pane checked from multiple angles before we leave.
All frames cleared of cobwebs and built-up debris.
Water marks and condensation staining treated and removed.
Specialist approach for sash windows and aged timber frames.
From Brooklyn brownstones and Manhattan apartments to Long Island bay windows and upstate family homes, we've worked on the full range of New York residential properties. Sash windows on older buildings need a different approach to modern double-glazed units, and we know the difference. Ground floor or four floors up - we handle it without fuss.
Get a Home QuoteManhattan storefronts, office blocks, hotels, restaurants, and retail spaces - urban grime and road salt make regular cleaning essential for any business that cares how it looks from the street. We work around your schedule, including early morning and after-hours slots, so your operation isn't disrupted. Regular contracts available for businesses that need a consistent service.
Request Commercial ProposalThe stretch from November through March is the harshest period for New York windows. Road salt gets spread heavily on streets and sidewalks, and it doesn't stay there - wind carries fine salt particles up and across every surface facing the road. By February, most street-facing windows have a thick, hazy film that's a mix of salt, exhaust residue, and condensation marks.
The problem with leaving it is that salt is corrosive. The longer it sits on glass in a freeze-thaw cycle, the deeper it can work its way into the surface. A proper post-winter clean in March or April - before the salt has had months more to settle - is genuinely worth doing to protect the glass long-term.
Standard cleaning products often just smear the salt around in cold conditions. We use treatments that actually dissolve and lift the residue cleanly, without streaking - even when temperatures are still low.
New York's water supply, combined with the mineral content in winter precipitation, leaves white chalky deposits on glass - especially on north-facing windows that don't get much direct sun and on properties near rivers or the coastline. It's particularly common on older buildings where the drainage around frames isn't perfect.
We use a specialist mineral treatment that breaks down the deposits without abrasives or anything that could scratch the glass. It's effective on most staining, especially when caught before the deposits have fully hardened into the surface.
If the staining is old and has etched deeply, we'll be straight with you about what we can and can't fix. There's no point taking money for a result we can't achieve.
For most New York homes, twice a year works well - a thorough spring clean to deal with everything winter has left behind, and an autumn clean to clear summer grime before temperatures drop again. If you're in Manhattan or a busy urban area with heavy traffic, quarterly cleaning keeps things consistently sharp.
Properties near the coast - Long Island, Staten Island, parts of Brooklyn - deal with the added complication of salt air on top of road salt, which tips the balance toward more frequent cleans. Commercial properties generally need monthly service, and anything with customer-facing glass in a busy location benefits from being on a regular schedule.

Experience with older New York building types and window styles.
We price based on what actually affects the job: the number of windows, the type of building, how many storeys you have, how accessible the windows are, and whether additional treatments like hard water or salt removal are needed. Older buildings and sash windows sometimes take a bit more care, and that's reflected honestly in the quote.
You get a clear, fixed price before any work starts. No surprises when the invoice arrives, no hidden call-out fees, no pressure to add services. We'd rather give you a price you're happy with and earn your repeat business than squeeze extra out of a one-off job.
"After last winter, the windows on our brownstone in Manhattan were absolutely grey. I honestly thought that was just how old glass looked, but it was road salt and pollution that had built up over three or four winters. Matty's team treated it properly and the difference was remarkable. Wish I'd called sooner."
- Claire O., Manhattan
"Our townhouse in Brooklyn has these old sash windows that I was worried about getting cleaned properly. Most companies just slap some cleaner on and squeegee it off. Matty's crew actually knew what they were dealing with - took their time, used the right products, and left every pane spotless without damaging anything. Really impressed."
- Marcus D., Brooklyn
"We've had a white mineral stain problem on the north-facing windows of our house for a couple of years - tried everything to get rid of it ourselves. Matty came out, explained what was causing it, treated it properly, and they're gone. He was also honest that one pane had some older etching that couldn't be fully reversed, which I appreciated."
- Patricia K., Buffalo
"Our house on Long Island is close enough to the water that the salt air is a constant battle, especially on the bay-facing windows. I've tried three different local companies over the years and none of them really dealt with it properly. Matty uses a different system and you can actually tell - the windows stay cleaner for longer. We're on a quarterly schedule now."
- James W., Long Island
