Commercial Window Cleaning Contract: Safety Standards and Pricing (Service Provider Guide)

A commercial job can be your most profitable (and repeatable) revenue stream—until a scope misunderstanding, a safety incident, or a payment dispute turns “easy recurring work” into weeks of emails, re-clean requests, or worse. That’s why a commercial window cleaning agreement isn’t just paperwork. It’s a tool to protect your crew, define deliverables, and get paid on time.

From a service provider perspective, the best window washing service contract does three things exceptionally well:

1. Sets clear expectations for scope, access, schedules, and quality.
2. Locks in safety standards (who does what, and what happens if conditions aren’t safe).
3. Defines pricing and change orders so you’re not donating labor.

Below is a comprehensive guide to writing and using a contract that supports safe operations and strong margins—including practical pricing structures you can include in a window cleaning contract template you use on every commercial bid.

---

Why commercial contracts matter more than residential

Commercial properties introduce operational variables that residential work usually doesn’t:

• Larger facades, multi-story access, lifts, roof work, and higher-risk environments
• Security procedures, badges, escort requirements, and after-hours cleaning
• Coordination with tenants, facilities, and building management
• Higher standards for insurance certificates, safety plans, and compliance documentation
• More complex billing: purchase orders, net terms, retainage, or multi-site invoicing

A contract makes these variables explicit—before your team shows up.

Core sections of a commercial window cleaning agreement (service-provider friendly)

A strong commercial window cleaning agreement should include the following sections. Think of this as your checklist when reviewing a window cleaner contract sample or building your own template.

1) Parties, property, and service areas

Be precise about who is hiring you and what you’re cleaning.

Include:

• Legal business names and addresses
• Contact names and authorized representatives
• Property address(es) and specific buildings (especially for multi-site clients)
• Areas included/excluded: exterior glass, interior glass, frames, sills, tracks, skylights, mirrors, atriums, glass railings, solar panels, etc.

Pro tip: Attach a “Service Area Exhibit” with annotated photos or a site map. This prevents disputes like “We thought the atrium glass was included.”

---

Safety standards: the contract terms that keep crews safe and liability predictable

Commercial window cleaning is inherently safety-sensitive. Your contract should not treat safety as a vague promise (“We’ll be careful”). It should set enforceable standards and define what happens when conditions aren’t safe.

2) Safety compliance and regulations

Use contract language that ties your work to recognized standards and local regulations.

Your contract can reference:

• OSHA requirements (U.S.) or applicable local workplace safety standards
• ANSI/IWCA I-14.1 (Window Cleaning Safety) where applicable
• Ladder, lift, rope descent, and fall protection rules
• Manufacturer instructions for equipment and anchorage systems

State that you will follow applicable laws and that the client will not request services that violate safety rules.

---

3) Access, site conditions, and “stop work” authority

Your crew needs contractual authority to pause or reschedule work when conditions are unsafe or access isn’t provided.

Include:

• Client obligations: clear access to windows, roof hatches, mechanical rooms, water source (if needed), parking/loading zones
• Security/escort requirements and any fees for delays
• Weather and environmental limitations (wind thresholds for lifts, storms, ice, etc.)
• A clear stop-work clause: your supervisor can stop work if safety is compromised, without being in breach

Example items to define:

• Wind speed limit for boom lift or rope work
• Minimum anchor certification requirements if rope descent is used
• What counts as “ready access” to rooftops and interior spaces
• How long you wait before a “no access” fee or trip charge applies

---

4) Equipment and method of access (ladders, lifts, rope descent)

Commercial clients often assume you’ll “bring whatever you need.” That assumption can destroy margins if you price for ladder work but need a lift.

Your contract should specify:

• Primary method(s) of access: ladders, water-fed pole, boom lift, scissor lift, rope descent system (RDS), suspended platforms
• Who provides lift equipment (you or the client)
• Who pays for lift rental, delivery, permits, and operator requirements
• Any additional pricing if access method changes due to site conditions

Service provider tip: include an “Access Method Change” clause: if the building requires a different method than the site walk suggested, you can issue a change order.

---

5) Fall protection, anchors, and rooftop safety

If you do any roof-access work, your contract should address the condition and certification of anchors and tie-off points.

Consider including:

• Client warranty/representation that roof anchors (if provided) are engineered, maintained, inspected, and certified
• Your right to refuse use of anchors that are unverified or appear unsafe
• Whether you will supply temporary anchors (if allowed) and what it costs
• Rooftop hazards: skylights, fragile surfaces, unprotected edges, locked access points

---

6) Hazardous materials and “unknown conditions”

Buildings can have hazards you won’t see during bidding (e.g., broken glass edges, chemical residue, bird waste, mold). Your contract should clarify the process if hazards are discovered.

Include:

• Client disclosure obligations for known hazards
• Procedures if your crew encounters unknown hazardous conditions
• Your right to stop work and propose remediation pricing
• Any exclusions: biohazard cleanup, construction debris removal, graffiti removal, mineral stain restoration unless specifically included

---

7) Insurance, certificates, and indemnity (keep it realistic)

Most commercial clients require:

• General liability
• Workers’ compensation (or equivalent)
• Auto liability
• Umbrella/excess coverage for larger sites

Your contract should state:

• Coverage you carry and how COIs are delivered
• Additional insured requirements (if agreed)
• Limitations: insurance is not a guarantee for client-caused conditions, and the contract allocates responsibility clearly

Because indemnity language can create huge risk, many window cleaning businesses have an attorney review their standard clause once, then reuse it consistently.

---

Scope and quality standards: prevent re-clean disputes

8) Scope of work (SOW): define “clean”

Commercial clients may have very different ideas of what “clean” means. Your contract should define the deliverables and quality benchmarks.

Include:

• “Interior and exterior glass cleaning” definitions
• Frames/sills/ledges: included or excluded
• Hard-water stain removal: usually excluded unless specified (restoration is different work)
• Paint/adhesive removal: included only if explicitly listed with pricing
• Post-construction cleaning: separate scope due to debris and risk

You can also specify:

• Visual inspection distance (e.g., “Final inspection at 10 feet under normal lighting”)
• Acceptable minor imperfections due to glass defects, scratches, failed seals, or existing damage

---

9) Existing damage and glass condition disclaimer

This clause is critical. Scratched glass disputes are common in commercial work.

Include language that:

• You are not responsible for pre-existing scratches, etching, seal failure, or defective coatings
• You will document obvious pre-existing damage when observed
• The client should report known glass issues before work begins
• Use of razors/scrapers requires approval and may be excluded unless the glass is confirmed safe (some coatings and tempered glass can scratch)

---

10) Scheduling, frequency, and after-hours pricing

Recurring contracts are where commercial window cleaning shines—if scheduling is clear.

Your agreement should specify:

• Frequency: monthly/quarterly/semiannual/annual
• Service windows: weekdays, weekends, after-hours
• Quiet hours or tenant restrictions
• Blackout dates and weather rescheduling policy
• Notice required for schedule changes

If you do after-hours work, define:

• Premium rates or minimum charges
• Lock/unlock responsibilities and fees for no access

---

Pricing structures for commercial window cleaning contracts

Pricing is where many service providers either win big or bleed slowly. Your contract should reflect how you price and what triggers additional charges.

Common pricing models (and when to use them)

1) Flat-rate per visit

Best for: predictable sites with consistent access.

Contract should include:

• Exactly what’s included in each visit
• Exclusions and add-ons
• Change order process if building changes (new partitions, added glass, etc.)

2) Price per pane / per window / per square foot

Best for: sites with consistent counting methodology.

Contract should define:

• What counts as a “pane” (divided lites vs single pane)
• Whether interior and exterior are separate line items
• Minimum service charge per visit

3) Hourly (time and materials)

Best for: variable conditions, restoration work, or unpredictable access.

Your window washing service contract should include:

• Hourly rates by labor category (tech vs supervisor)
• Minimum hours per visit
• Billing increments (e.g., 30-minute increments)
• Materials/equipment charges and approval rules

4) Tiered pricing by difficulty or height

Best for: mixed low/high glass, atriums, skylights, or lift-required areas.

Example tiers:

• Ground level (ladder/water-fed pole)
• 2–3 stories
• Lift-required zones
• Rope descent zones (specialized labor)

5) Retainer or subscription-style recurring plan

Best for: multi-location clients who want predictable monthly billing.

Contract should specify:

• Monthly fee and number of visits included
• What happens if a visit is skipped due to weather/access
• True-up process for additional work

---

Pricing clauses that protect margin

Add these pricing-related terms to your commercial window cleaning agreement:

• Mobilization/trip fees for no-access or client-caused delays
• Change orders required for added scope (new glass, tenant build-outs, post-construction mess)
• Lift rental and permits billed as pass-through costs plus coordination fee (if applicable)
• Fuel/parking/tolls reimbursement in urban areas
• Emergency call-out rates
• Minimum invoice amount per visit (especially for small storefront routes)

---

Payment terms: reduce late payments and admin friction

Commercial billing can be slow if you don’t set rules upfront.

Include:

• Deposit (if any) and whether first month is due upon signing
• Invoice timing: upon completion, net 15/net 30, recurring billing date
• Late fees/interest (where legally allowed)
• Collections: client responsible for reasonable collection costs
• Dispute window: client must report issues within X days or it’s deemed accepted
• Taxes: sales tax/VAT treatment depending on jurisdiction
• PO requirement: if a PO is required, client must provide it before service begins

---

Change orders and additional services: your best defense against scope creep

A change order clause should answer:

• Who can approve changes (name/title)
• How pricing is calculated (flat fee, hourly, per square foot)
• Whether changes affect schedule
• Whether work proceeds only after written approval (email counts, if you choose)

Typical add-ons to address:

• Hard-water stain removal/restoration
• Construction clean (silicone, paint overspray, adhesive)
• Screen cleaning, track detailing
• Pressure washing or facade rinse
• High dusting or chandelier cleaning
• Mirror and interior glass partitions

---

Term, renewal, and termination: keep recurring revenue stable

For recurring commercial work, your term section should be clear.

Consider:

• Initial term (e.g., 12 months)
• Auto-renewal (where legally permitted) with notice window
• Termination for convenience (e.g., 30 days’ notice)
• Termination for cause (nonpayment, unsafe conditions, repeated no-access)
• What happens to scheduled services if terminated mid-cycle
• Final invoice and payment due date

---

A practical “window cleaning contract template” structure (outline)

If you’re building or updating a window cleaning contract template, use this structure:

1. Parties and property details
2. Scope of work + service areas (Exhibit A)
3. Schedule and frequency
4. Access and site responsibilities
5. Safety standards, equipment, and stop-work authority
6. Pricing and included services
7. Add-ons, exclusions, and change orders
8. Payment terms and invoicing
9. Damage disclaimer and pre-existing conditions
10. Insurance and liability allocation
11. Term, renewal, and termination
12. Dispute resolution and governing law
13. Signatures and exhibits (maps/photos, pricing tables, service checklist)

This outline also makes it easier to compare any window cleaner contract sample you find online—so you can spot what it’s missing.

Common mistakes window cleaning contractors make in commercial contracts

1. Vague scope (“clean all windows”) with no exclusions
2. No access rules, leading to wasted trips and crew downtime
3. No safety stop-work clause, pressuring techs into unsafe conditions
4. Pricing that doesn’t match access method, especially lifts and atriums
5. No damage disclaimer, inviting scratch claims
6. No change order process, causing unpaid add-on work
7. Weak payment terms, resulting in net-60 surprises or billing confusion

---

Tips for presenting your commercial window cleaning agreement to clients

• Send the contract with a simple pricing exhibit (table format) and a one-page scope summary
• Use photos from the walkthrough to confirm what’s included
• Make safety terms matter-of-fact: “This protects both parties and ensures compliance”
• Don’t “hide” key terms—clarity reduces negotiation friction
• Keep a versioned template and update it annually based on real job lessons
