Quick answer
Most properties need facade & glass cleaning every 3–6 months for facades, ducts and floors, and once at handover for post-construction work. High-traffic sites, food businesses and hospitals need it more often, and the two highest-priority windows each year are just before and just after the monsoon. Keep dated records so you can prove the interval was followed.
Key takeaways
- Standard frequency: every 3–6 months for facades, ducts and floors, and once at handover for post-construction work
- Pre- and post-monsoon are the two most important visits of the year
- Food businesses, hospitals and hotels should shorten the interval
- Keep dated records for audits, AGMs and disputes
- Set a fixed schedule with an annual contract so it's never missed
- Act sooner if any of the warning signs below show up
Recommended frequency
Clients usually ask this once, then want it on a calendar so it never comes up again.
For builders, property managers, hotel engineers, restaurant owners, hospital administrators and retail chains, we recommend facade & glass cleaning every 3–6 months for facades, ducts and floors, and once at handover for post-construction work.
Frequency by property type
Here's how that recommendation changes depending on what kind of site it is:
| Property type / scenario | Recommended frequency | Why |
|---|---|---|
| Facade/high-rise glass | Every 3–6 months | Dust, pollution film and hard-water spotting build up steadily |
| Kitchen exhaust & ducts | Every 1–3 months (commercial kitchens) | Grease accumulation is a continuous fire-safety risk |
| Marble/stone floors | Polish every 6–12 months; scrub more often | Foot traffic dulls the finish over time |
| Post-construction cleaning | Once, at handover | A one-time deep clean before occupancy or opening |
| Sanitization/fogging | Monthly, or after an illness event | Surface disinfection decays with normal use and touch |
Best time of year
Facades are best cleaned right after the monsoon; kitchen ducts every quarter; post-construction cleaning right before handover or opening.
Facades are best cleaned right after the monsoon, once windblown dust and water staining have settled, since cleaning during heavy rain is often unsafe and ineffective. Duct and floor work are less weather-dependent, but post-construction cleaning timelines often get compressed around the monsoon as builders rush to complete handovers before rains damage unfinished work.
When to book sooner than scheduled
Move your date up if you notice:
- Complaints from residents, staff or guests
- Visible dirt, odour or stains before the next scheduled date
- An upcoming audit, inspection or event
- Flooding, renovation or a long closure
- A change in water source, usage pattern or occupancy
Good to know
If health symptoms are involved (stomach upset, skin irritation), treat it as urgent and don't wait for the next scheduled date.
Why skipping an interval hurts
Jobs like facade cleaning, duct cleaning, sanitization and post-construction cleaning need special equipment and safety training. Doing them wrong can cause falls, fire risk, damaged surfaces or incomplete disinfection.
This holds true for facade & glass cleaning specifically, not just in general.
What changes the interval for your site
High-rises in business districts of Mumbai, Thane and Navi Mumbai need BMU or rope-access facade cleaning with building management's permission, while older low-rise buildings can often be done with ladders and boom lifts. Restaurants across these areas face routine fire-safety expectations for grease-free exhausts, and new residential and commercial handovers in fast-developing belts like Panvel generate steady post-construction cleaning demand.
Keeping to the schedule
Contract clients get scheduled visits and reminders, so facade & glass cleaning happens on date rather than after someone notices a problem. Commercial Cleaning Mumbai can align this with your AGM, audit or financial-year calendar.
