Handover day, and the glass finally looks new.
Post-construction window cleaning for commercial sites. Stucco, mortar, paint and label glue taken off new glazing without marking it, on a schedule that fits the rest of the trades.
For builders and property managers
New glazing is the easiest glazing to ruin.
Glass that has been through a build is not dirty in the ordinary sense. There is drywall dust bonded into the surface, overspray from the painters, silicone smeared along the edge seal, mortar splash down the elevations facing the masonry, and manufacturer labels that have sat in the sun for a season. A cloth just drags the grit across the pane and scratches it.
The order matters more than the effort. Soak the pane, let it dwell, take the solids off with a fresh blade held flat on wet glass, then wash it properly and detail the frames, tracks and sills. That last part is where the build debris actually sits, and it is the part that gets skipped when a clean is priced by the pane.
Tempered glass is identified before anything touches it. Storefront and door glass is usually tempered, its surface carries fabrication debris from the factory, and it will scar in a way annealed glass does not. Anything we are unsure about gets tested in a corner first and photographed if it is already damaged, so nobody is arguing about it at handover.
- Scheduled around the trades We come in once the messy work is done, not while the painters are still on site.
- Tempered glass identified first Because it marks in a way ordinary glass will not.
- Frames, tracks and sills Where the drywall dust and mortar actually collects.
- Insured for site work Documentation sent over whenever your GC or building owner asks for it.
What is included
What comes off.
Everything a commercial build leaves on the glazing, plus the frames nobody else touches.
Builder film and label glue
Protective film, tape residue and baked-on manufacturer stickers.
Paint and primer overspray
Specks and runs lifted off the pane rather than ground into it.
Stucco, mortar and grout
Softened and floated off, which matters most on the masonry elevations.
Silicone and caulk
Off the glass and off the frame edge, without cutting the seal.
Drywall dust and plaster
Including the haze it leaves across a whole elevation.
Frames, tracks and sills
Vacuumed and wiped so the doors and openers run properly again.
On the job
What it looks like in practice.

How it works
How a commercial post-construction clean runs.
We walk the site with you first
Elevations, access, which glass is tempered, and anything already scratched gets photographed before we start.
Solids come off wet, never dry
Soak, dwell, blade flat. This is the stage that decides whether the glass survives.
Then the full clean and the frames
Every pane washed and detailed, then a walk round with your site contact before we invoice.
Pricing
What changes the price.
Commercial post-construction is quoted per site rather than per pane, because two buildings with the same glass area can be a day apart depending on what is on it and how we reach it.
How much is on the glass
Light dust is quick. Cured mortar and overspray is a different job.
Glazed area and pane size
Curtain wall and big storefront lites take longer than punched openings.
Access
Ground level with a pole is cheapest. Lifts, scaffold and interior heights all add time.
Tempered glass
Handled more slowly and carefully, which costs more and is worth it.
Phasing
One clean at the end is cheaper than a rough clean plus a final.
Timing
Evenings and weekends can be arranged when the space is already occupied.
FAQs
Questions we get asked.
Do you work while other trades are still on site?
We would rather not, and you would rather we did not. Glass cleaned before the painters finish gets done twice and billed twice. If the programme means overlap is unavoidable, we phase it by elevation and come back for the areas still in progress.
Can you provide insurance documentation?
Yes. Liability coverage applies to every commercial job and we send the certificate over whenever your general contractor, property manager or building owner asks for it.
What if the glass is already scratched when you arrive?
We photograph it before we touch it and send you the photos the same day. Scratches from fabrication debris or from another trade are common on new builds, and the time to establish who caused them is before the cleaner shows up, not after.
Do you do the interior as well?
Yes, and on a new build the interior is usually the dirtier side. Interior glazing, partitions and any interior storefront can all be included.
How high can you reach?
Water-fed poles cover most low-rise and multi-storey work from the ground. Above that we quote lift or scaffold access, and we will tell you honestly when a job wants a specialist rather than us.
Can you clean before occupancy on a tight date?
Usually. Tell us the handover date when you enquire rather than when you book, because the last week before occupancy fills up and it is the week everybody wants.
