Commercial Window Washing: Schedules, Contracts and What Property Managers Should Ask

Clean glass is the first thing tenants, customers, and inspectors notice about a building. It’s also one of the easiest services to get wrong. Without a clear schedule and a written contract, you end up with missed visits, disputed invoices, and unclear liability if something goes wrong at height.

This guide covers how often commercial window washing should happen, what a solid contract includes, and the questions property managers should ask before signing. It’s written for North Vancouver properties, where rain, salt air, and tree pollen change how quickly glass gets dirty.

Quick answer: Most North Vancouver commercial properties need window washing every 1 to 4 weeks at street level and 2 to 4 times a year above ground floor. Always put the scope, frequency, insurance, and re-clean terms in a written contract.

What Is Commercial Window Washing?

Commercial window washing is the scheduled cleaning of glass on business properties, including storefronts, offices, strata buildings, restaurants, clinics, and high-rises. It differs from residential service in scale, access equipment, liability requirements, and recurring contracts.

Three things set it apart:

Volume. A single visit may cover hundreds of panes across several floors.
Access. Work may need ladders, water-fed poles, swing stages, or rope access.
Accountability. Property managers need proof of insurance, safety procedures, and a service record.

If you’re comparing providers, our commercial window washing services in North Vancouver cover storefronts, offices, and multi-storey buildings.

How Often Should Commercial Windows Be Washed?

Commercial windows should be washed every 1 to 4 weeks for street-level storefronts and restaurants, monthly for medical and office entrances, and 2 to 4 times a year for upper floors, strata buildings, and high-rises. The right frequency depends on foot traffic, exposure, and how much your brand depends on clear glass.

Property type	Typical frequency	Why
Retail storefronts	Every 1–4 weeks (exterior)	Street-level glass collects fingerprints, road grime, and rain spots fast
Restaurants and cafés	Every 1–2 weeks	Customer-facing glass and entry doors get constant contact
Medical and dental clinics	Monthly	Professional image and frequent door traffic
Low-rise offices	Quarterly	Moderate exposure, mostly ground-floor glass
Strata and multi-unit buildings	Twice a year (spring and fall)	Large glass area, lower contact
High-rise buildings (7+ storeys)	2–4 times a year	Access cost is high, so visits are scheduled around weather
Industrial and warehouse	1–2 times a year	Low customer exposure

These are general guidelines, not rules. Adjust them to your building.

What changes your window washing schedule?

Proximity to water. Salt spray near Lower Lonsdale and the waterfront crystallizes on glass faster than it does inland.
Tree cover. Pollen and sap from the surrounding forest build up quickly, especially in spring.
Traffic. Buildings along Lonsdale Avenue and Marine Drive pick up more road film.
Construction nearby. Dust and overspray from neighbouring sites can dirty glass between visits.
Wet season. Rain from October to March leaves mineral spots, so many properties add a visit before winter.

Which Window Washing Methods Does Your Building Need?

The right method depends on height and glass type. A good company recommends the safest option, not the cheapest.

Method	Best for	Notes
Squeegee and ladder	Storefronts and low glass	Quick for ground-level work
Water-fed pole with purified water	Buildings up to about 6 storeys	Leaves no residue, avoids ladders, reaches high glass from the ground
Swing stage or rope access	High-rise exteriors	Requires trained crews, fall protection, and site coordination
Interior squeegee	Offices, lobbies, glass partitions	Scheduled around business hours

WorkSafeBC rules generally require fall protection when workers could fall more than 3 metres, so anyone quoting high-access work should explain their safety plan clearly. If a bidder can’t, treat that as a warning sign.

What Should a Commercial Window Washing Contract Include?

A commercial window washing contract should state the scope of work, service frequency, pricing model, insurance, safety procedures, and re-clean and cancellation terms in writing. Vague contracts are the main cause of disputes.

Here is a checklist you can use:

Scope of work. List which windows, floors, and sides are included, and whether interior glass, frames, sills, tracks, and screens are covered.
Frequency and dates. Specify the schedule (weekly, monthly, quarterly) and how missed visits are rescheduled.
Access and timing. Note after-hours or early-morning windows, building access, and any tenant notice requirements.
Pricing model. State whether the price is per pane, per visit, or a flat monthly fee, and what triggers extra charges.
Proof of insurance. Require a certificate showing commercial general liability coverage, and ask to be named as an additional insured.
WorkSafeBC standing. Ask for a clearance letter showing the contractor’s account is in good standing.
Safety procedures. Require a written fall protection plan for any work at height.
Weather policy. Define when work is postponed for rain, wind, or ice, and how quickly it is rescheduled.
Re-clean guarantee. Set a window for reporting missed spots, such as 24 hours, and require a free return visit.
Term and cancellation. Specify the contract length, notice period, and any price escalation.
Damage and claims. Describe how damage to glass, frames, or landscaping is reported and resolved.
Subcontracting. Require disclosure if any work is handled by another company.

If you also manage janitorial services, compare terms using our commercial cleaning contract checklist so scopes don’t overlap.

What Should Property Managers Ask a Window Washing Company?

Property managers should ask about insurance, safety, equipment, scheduling, guarantees, and references before awarding a contract. These ten questions separate professionals from risky operators:

Are you fully insured, and can you send the certificate today?
Is your WorkSafeBC account in good standing?
What equipment will you use on my building’s height and glass type?
What is your fall protection procedure for work above ground level?
Who will actually be on site, and are they employees or subcontractors?
How do you handle rain, wind, and rescheduling?
What’s your re-clean policy if we find missed spots?
Can you work early morning or after hours to avoid disrupting tenants?
How is the price structured, and what could change it?
Can you provide local references from similar buildings?

Watch for red flags: no proof of insurance, cash-only payment, vague scope, no safety plan, and pricing far below other bids. Our guide on red flags when vetting a cleaning company covers more warning signs, and our article on choosing a commercial cleaning company in North Vancouver explains how to compare proposals side by side.

How Is Commercial Window Washing Priced?

Most companies price commercial window washing in one of four ways: per pane, per visit, flat monthly fee, or hourly. Per-pane pricing is the most transparent for large buildings, while flat monthly fees suit recurring storefront service.

Price depends on pane count, height, access method, soil level, and frequency. Cleaning more often usually lowers the cost per visit because glass isn’t heavily built up. For typical ranges and what affects them, see our window cleaning cost guide for North Vancouver, and for broader budgeting see our commercial cleaning cost guide.

Can You Bundle Window Washing With Other Commercial Services?

Yes, and it often simplifies scheduling and invoicing. Many property managers combine window washing with commercial cleaning in North Vancouver for offices and common areas. New builds and renovations often need post-construction cleanup before the first scheduled wash, since paint overspray and adhesive residue need specialized treatment.

Frequently Asked Questions

How often should commercial windows be washed?

Storefronts and restaurants usually need washing every 1 to 4 weeks. Offices and clinics fit monthly or quarterly schedules. Upper floors and high-rises are typically washed 2 to 4 times a year.

Do commercial window washers need insurance?

Yes. Ask for a certificate of insurance showing commercial general liability coverage before work begins, and confirm the contractor’s WorkSafeBC account is in good standing.

Is a window washing contract necessary?

For recurring service, yes. A written contract protects both sides by defining scope, frequency, insurance, and re-clean terms.

Can window washing be done in the rain?

Light rain is usually fine with water-fed pole systems, but crews reschedule for heavy rain, wind, or ice. Your contract should say how quickly missed visits are rebooked.

How do I find a commercial window washing company near me?
