Post Construction Cleaning in Montreal, QC
Home / Services / Post-Construction Cleaning
A build or renovation isn’t really finished the moment the last trade packs up. Drywall dust settles into window tracks, shingle grit fills up the gutters, and construction residue coats the siding and walkways, none of which a regular cleaning crew is set up to handle properly. Spic and Span Window Washing provides post construction cleaning for homeowners across Montreal and the surrounding area, clearing windows, gutters, and exterior surfaces in one visit so the property is genuinely ready, not just clean at first glance.
We work with homeowners after a new build, a full home renovation, or a smaller job like a roof replacement or an addition. The residue changes depending on the project, but what we’re aiming for stays the same: nothing left behind that gives the build away.
What Post Construction Cleaning Involves
Construction leaves behind residue that a damp cloth won't fully lift. Our post construction cleaning covers the three areas where that residue actually causes problems if it's left alone.
Windows and glass pick up drywall dust, caulking haze, and sometimes light paint overspray. We clean the glass, frames, tracks, and screens with a proper glass cleaning process, not a quick squeegee pass that just pushes the film around.
Gutters catch shingle grit, sawdust, and packaging debris during a build. We clear this out by hand and finish with a downspout flush to confirm water is actually draining, not just that the top of the channel looks empty.
Exterior surfaces like siding, brick, concrete, and walkways all take on dust and residue during construction. We pressure wash at a setting matched to the material so residue comes off without stripping or damaging surfaces like vinyl or stucco.
How We Approach the Job
Rushing a post construction exterior doesn't hold up well. Fine dust has a way of resettling once it's disturbed, so we work through the property in stages instead of trying to finish everything in one pass.
We start by clearing the bulk: loose debris, packaging, and heavy dust removed first so nothing spreads further while we work. Then comes the detailed clean, where the glass gets its dedicated treatment, gutters get manually cleared and flushed, and exterior surfaces get pressure washed. A short follow up visit a day or two later catches any dust that resettles on the glass and confirms the gutters are still draining properly once the property has had time to settle.
Protecting What You Just Paid For
Construction residue doesn’t just look bad, left alone it does actual damage. Drywall film on glass hardens further with sun exposure and gets harder to remove the longer it sits. Debris packed into a gutter through even one freeze thaw cycle compacts into something closer to cement than leaves, and Montreal winters give it plenty of chances to do exactly that. A cleaning booked before the first hard freeze protects the seams and brackets holding your gutter system together. Skip it, and a straightforward first cleaning can turn into a harder, more expensive one by spring.
Why Homeowners Choose Us for This
Not every cleaning company that offers post construction work is actually set up to do it properly. It comes down to equipment and access more than effort. Here's what comes with booking Spic and Span:
We're fully insured and experienced with ladder and rooftop access. We handle windows, gutters, and exterior surfaces in one coordinated visit, so you're not juggling three separate appointments with three separate companies. Every gutter cleaning comes with a 3 month guarantee, and the follow up check is built into the process rather than billed as an extra. We serve Montreal, Laval, Hudson, Kirkland, and the surrounding communities.
We see the same pattern often. A homeowner clears the visible layer themselves, and a few weeks later calls about streaked glass or a gutter backing up in a heavy rain, because the debris underneath the surface was never actually removed. That's exactly the part professional equipment and technique are built for.
What Affects the Price
Every property is different, so we don't quote off an average. What actually moves the price is the size of the home and how many stories it has, the scope of the project (a full new build versus a single room renovation or a roof replacement), and how much time has passed since construction wrapped up, since residue that's had months to harden simply takes longer to remove.
Bundling windows, gutters, and exterior surfaces into one visit is almost always cheaper than booking them separately, and it means one crew shows up with everything needed to finish the job in a single pass.
Questions Worth Asking Before You Book Anyone
Not every company that lists post construction cleaning is actually built for it. Before hiring anyone for this job, it's worth asking whether the quote covers windows, gutters, and exterior surfaces or just one of the three, whether they flush the downspouts or only clear what's visible from the ground, what pressure washing settings they use on siding versus concrete or brick, and whether they're insured for ladder and rooftop work.
If a company can answer all of that without hesitation, it's usually a good sign they've done this enough times to know where the problems actually hide.
Frequently Asked Questions
Have Any Questions
Gutters are included as standard, not an add on. Roofing work especially leaves shingle grit and debris that settles low in the channel, so we clear it manually and flush the downspouts to confirm water is actually draining.
Right after the last major trade finishes, whether that’s flooring, painting, or exterior work, but before move in or a final walkthrough. Booking while trades are still finishing usually means redoing part of the cleaning once the last few tasks wrap up.
Not when it’s set correctly for the material. We adjust pressure and technique depending on what we’re cleaning, since vinyl siding and stucco need a gentler approach than brick or concrete, which is where most damage from DIY pressure washing actually happens.
No, as long as we have access to the exterior, gutters, and any locked gates. We’ll confirm access details when you book your estimate.
