We had Igor from Veco windows replace the glass in our awning-type kitchen window after the seal was broken. Our estimate for completely replacing the window was over $1500, but to just replace the glass was about $400 through Veco. We were very happy with a fix that was 1/4 the price of a full replacement. It took a couple of hours. Igor was professional, methodical, neat, and made it look like new. We were very happy. Thank you Igor!

Skylight Window Cleaning in Arlington Heights, IL and What Hard Water Really Does

What Hard Water Actually Does to a Skylight — A Real Project in Arlington Heights, IL

Look closely at the before photo. What appears to be frosted or etched glass isn't a design feature — it's years of calcium carbonate, mineral silicate, and hard water residue that has bonded directly to the outer surface of a roof-mounted skylight on a residential property in Arlington Heights, IL. The glass underneath is perfectly intact. Getting back to it required the kind of targeted professional treatment that goes well beyond a standard wash, which is precisely why this homeowner called in the skylight window cleaning in Arlington Heights, IL specialists at VECO.

Arlington Heights: Where Hard Water and Mature Landscaping Are Both Facts of Life

With a population approaching 75,000, Arlington Heights is one of the largest and most established municipalities in the northwest Chicago suburbs. Its neighborhoods range from post-war ranch homes near downtown to larger two-story properties spreading out toward the borders with Buffalo Grove, Palatine, and Wheeling. What connects them all — aside from the Metra Union Pacific Northwest line threading through the village center — is the regional water supply. The Chicago metro area draws from Lake Michigan, but distribution through aging local infrastructure often means elevated mineral content by the time water hits roof surfaces as rain, irrigation overspray, or condensation runoff. On a horizontal or near-horizontal surface like a skylight, that water doesn't drain quickly — it sits, evaporates, and leaves its mineral content behind. Repeat that process across several seasons and the result is exactly what you see in this before photo

Reading the Before Image

The skylight here is a single large flush-mount unit set into an asphalt shingle roof — a standard configuration in Arlington Heights homes built from the 1980s onward. The glass surface in the before photo is almost completely obscured by a white-grey mineral film that has formed a continuous crust across the entire pane. This isn't surface dirt that responds to soap and water — it's calcium and silica scale that has partially bonded to the glass at the molecular level through repeated wet-dry cycling. The metal frame shows secondary staining from oxidized runoff tracking down from the flashing, adding another layer of contamination around the perimeter.

From inside the house, this skylight would have been admitting perhaps 30 to 40 percent of available light — the rest blocked entirely by opaque mineral buildup.

VECO Restores Mineral-Encrusted Skylight Glass in Arlington Heights, IL

The Treatment: Mineral Dissolution Before Cleaning

Our expert window washers in Arlington Heights, IL assessed the skylight on arrival and identified the primary deposit as calcium carbonate scale with silica bonding — a combination that requires a staged approach rather than a single cleaning pass. We applied a professional descaling solution formulated specifically for glass surfaces, allowing adequate dwell time for the chemistry to break the mineral bond without affecting the glass coating or surrounding roofing material. The loosened scale was then carefully removed and the surface rinsed with deionized pure water to prevent any new mineral spotting during drying.
The after photo captures the result: a fully transparent pane with the bare winter tree canopy clearly visible as a reflection in the glass — detail that was completely invisible before treatment. The frame perimeter was also addressed, removing the rust-colored oxidation streaking that had tracked down from the flashing.

A Note on Permanent Etching

This project had a successful outcome, but it's worth being direct: mineral scale left on skylight glass long enough will eventually etch the surface permanently. At that stage, no amount of cleaning restores full clarity — the glass requires replacement. The line between reversible scale and permanent etching depends on the mineral concentration, the duration of exposure, and whether any previous cleaning attempts used abrasive methods that accelerated surface degradation. This Arlington Heights skylight came in just on the right side of that line. Waiting another season may not have had the same result.
