Post-Construction Window Cleaning in Saint-Hubert

Picture a couple in Saint-Hubert who have just finished a kitchen addition on their two-storey home. The contractor leaves the windows covered in drywall dust, paint flecks and a thin film from the new sealant. They try wiping the inside glass themselves and end up with streaks that show every time the sun hits. That's when post-construction window cleaning in Saint-Hubert makes sense.

The specific mess construction leaves behind

New builds and renovations in Saint-Hubert create a different kind of dirt than normal household grime. Fine plaster powder settles into every corner of the frame. Overspray from primer lands on the exterior panes. Silicone residue from caulking clings to the glass and won't come off with ordinary soap. A regular maintenance clean that only hits the surface will miss much of it.

Tracks are the worst. Builders rarely vacuum them during final cleanup, so you get a mix of sawdust, metal shavings and dried adhesive. If you don't clear that out before the first rain, it turns into a gritty paste that scratches the sill every time the window slides.

How we approach post-construction jobs

Because the amount of residue varies so much from one project to the next, post-construction cleanup is quoted separately from our regular flat-rate visits. Tell us what was done and what you want covered, including screens and tracks, and we price the job from there.

Exterior work uses pure water on water-fed poles. The deionized water lifts dust and residue without leaving mineral spots. On a typical Saint-Hubert two-storey, the pole reaches the upper windows from the ground, without setting a ladder against fresh siding. Our poles reach up to three storeys; taller homes or difficult access get a site visit first. Inside, glass is detailed with a squeegee and microfibre, with extra passes on any pane that still shows haze.

When tracks are part of the job, they get a vacuum pass followed by a damp microfibre cloth, and screens are removed, washed and left to dry before going back in. That keeps dust from blowing back onto clean glass the first time you open a window.

What about streaks after the crew leaves?

Every window is spot-checked before the crew leaves. A pane near a new range hood can carry a faint grease film from the install, and that's exactly what the check is for. If you still see a streak afterward, contact us within 24 hours and the crew returns to re-clean it at no charge.

Before you hire anyone for this kind of job, ask for a clear price that spells out what's covered. That way there are no surprise charges once the crew sees how dusty the screens are.

Weather and timing in Saint-Hubert

Exterior work runs roughly from March to November, and interior glass can be done year-round. Spring and fall are comfortable seasons for this work; on very hot days, crews work around direct sun on south-facing glass. If weather makes the work impractical on your day, we rebook your visit.

After the construction mess is gone, many homeowners switch to regular maintenance. Our spring and fall and annual programs come with an automated reminder before your next visit. Quarterly (10%), bi-monthly (15%) and monthly (20%) plans come with a discount.

Questions to ask any crew

On new construction, one scratch on fresh paint or siding can turn into a dispute. Ask any company what its coverage is and how it reaches upper windows. Working from the ground with water-fed poles keeps ladders off new siding entirely.

The lack of detergent residue from pure water is the detail that matters most after a renovation: the glass stays clearer through the first heavy rain instead of streaking.

For regular cleaning afterward, our flat rate by window count keeps things simple. You pick your tier online, and the price covers exterior glass, frames and sills, with screens rinsed in place. Interior glass, screen removal and washing, and track cleaning are optional add-ons at extra cost.

Who should book this service

Anyone finishing a renovation or new build in Saint-Hubert where windows were left untouched during final cleanup. It's also useful after a major interior paint job that left overspray on the glass. Once the construction dust is cleared, a spring and fall routine makes sense for most homes, especially once you've seen how fast dust returns in the fall.

Frequently asked questions

When should I book window cleaning after a renovation in Saint-Hubert?

Book it once the contractor's final cleanup is done, and ideally before the first heavy rain. Rain turns the sawdust, metal shavings and adhesive left in the tracks into a gritty paste that scratches the sill. Exterior work runs roughly from March to November; interior glass can be done any time of year.

How long does post-construction window cleaning take on a two-storey home?

It depends on how much residue the project left behind and whether screens and tracks are included. That's part of why post-construction work is quoted separately: we look at the details of your project before setting a price.

Does post-construction window cleaning cost more than a regular cleaning?

It's priced separately from our regular window-count tiers, because paint, sealant and plaster residue take more time than seasonal grime. Contact us with your project details to get a price before anyone arrives.

Why do my new windows still look hazy after I wiped them?

Construction leaves plaster powder, primer overspray and silicone film from caulking, and ordinary soap and a cloth mostly smear them around. Removing that film takes pure water on the exterior and a squeegee with microfibre inside, with extra passes on any pane that stays hazy. Clearing the tracks also stops dust from blowing back onto the clean glass.

If the windows on your Saint-Hubert home still show construction residue after a basic wash, contact us with your project details for a price. For regular cleaning afterward, see our window-count tiers. More from the Altara blog covers seasonal timing and different home styles around the Rive-Sud.
