When to Clean Windows in Lorraine: A Practical Guide

I’ve cleaned windows in Lorraine for years, and I’ll tell you straight: timing matters more than most people think. It’s not just about wiping glass when it looks dirty. It’s about protecting your investment, avoiding rework, and getting the most out of every visit. Lorraine’s climate — with its humid springs, pollen-heavy air, and crisp autumns — creates a rhythm that smart homeowners follow.

Why timing isn’t just about appearance

Most folks wait until they can see streaks or smudges from the street. By then, dirt’s already baked in. Pollen, dust, and mineral deposits from rain don’t just sit on the glass — they etch into it over time. I’ve seen older homes in Lorraine where neglect led to permanent haze, especially on south-facing windows that bake in the sun. Cleaning isn’t cosmetic. It’s maintenance.

And let’s be real: if you’re paying for a service, you want it to last. A clean window in early May might look terrible by June if you didn’t time it right. That’s not the cleaner’s fault — it’s the schedule.

Spring cleaning: the non-negotiable

Spring is the big one. In Lorraine, pollen starts flying in late April and peaks through May. If you wait until June, you’re cleaning off a month’s buildup — and your screens will be clogged before you even finish. I recommend booking for early to mid-May. That way, you catch the tail end of tree pollen before grass pollen hits hard.

What does Altara do in spring? We remove screens, wash them with mild soap, vacuum tracks, wipe sills, and clean both sides of the glass with pure-water poles outside and microfiber squeegees inside. No streaks. No residue. And yes, we put the screens back in — no extra charge.

One gripe I have? Some competitors quote low, then add $25 per screen ‘because it’s extra work.’ That’s nonsense. Screens are part of the window. If you’re not cleaning them, you’re not doing the job.

Fall cleaning: prep for winter

Fall is the second window — literally and figuratively. In Lorraine, September and early October are ideal. The air’s cooler, pollen’s down, and you’re clearing off summer dust, bug residue, and tree sap before snow and ice arrive. Clean windows in fall mean less condensation buildup over winter, and you’re not starting spring with a dirty slate.

I love this about our bi-annual program: automated reminders. You pick spring only, or spring + fall, and we nudge you when it’s time. No need to remember. No missed visits. It’s simple, and it works.

What about summer or winter?

Summer? Only if you’ve got construction nearby, or you’re prepping for a big event — a graduation, a family reunion, a backyard wedding. Otherwise, skip it. The sun dries cleaning solution too fast, and you risk streaks. Plus, you’re just re-cleaning pollen that’ll come back anyway.

Winter? Almost never. Exterior cleaning with water-fed poles risks freezing on the glass or the frame. We’ll do interior only if there’s a leak or condensation issue, but full service? Wait for thaw. And no, we don’t use pressure washers or de-icers on glass — that’s a fast way to crack a pane or damage seals.

How do you know it’s time?

Here’s my rule: if you can write your finger in the dust on the sill, it’s time. If the screens look gray instead of black, it’s time. If the rain leaves spots that don’t wipe off with a dry cloth, it’s time. Don’t wait for obvious streaks — that’s late.

And if you live near a busy boulevard or construction zone in Lorraine — say, along Boulevard des Mille-Îles or near the industrial corridor — you might need to clean more often. Dust and exhaust stick faster there.

What Altara actually includes (no upsells)

Every standard visit includes: interior glass, exterior glass, screens (removed, washed, reinstalled), tracks (vacuumed and wiped), sills, and eaves dust when reachable from the outside. Pure-water system for exterior — no chemicals, no mineral residue. Squeegee and microfiber for interior. That’s it. No hidden fees for ladders, no extra for second-storey homes (standard in Lorraine), no ‘premium’ tier for basic service.

One concrete love? Our streak-free guarantee. If you see a streak after we leave, call within 24 hours. We come back — free. No arguments, no ‘it’s not our fault.’ I’ve used it myself once, after a particularly dusty spring. They were back the next day. That builds trust.

Pricing: flat rate, no surprises

We don’t do in-home quotes. You go online, enter your window count, and get a flat rate in under an hour. No salesperson showing up to ‘assess’ your home. For a typical two-storey detached home in Lorraine — say, 18 to 22 windows — you’re looking at a range that reflects the work: screens, tracks, both sides of glass. I won’t give a number here because every home’s different, but I will say this: if a quote seems too low, ask what’s missing. Chances are, screens or tracks aren’t included.

And yes, the bi-annual program saves you money over two separate visits. It’s not a huge discount, but it’s real — and the automated reminders mean you don’t have to think about it.

Who should consider Torrent instead?

If you live in a three-storey home in Lorraine with steep roof access, or you’ve got skylights that need rope work, we’ll refer you to Torrent — our sister division for higher-access jobs. Altara stays residential, two-storey and under, ladder or pole access. We know our limits.

Final thought

Clean windows aren’t about vanity. They’re about light, clarity, and taking care of your home. In Lorraine, the rhythm is clear: spring to clear the pollen, fall to prep for winter. Stick to that, and you’ll get more life out of your glass, better views, and fewer headaches.
