Commercial window cleaning preparation starts with the approved scope: which glass is included, whether the work is inside, outside, or both, and how the crew will reach each area. Before the service date, confirm the work hours and onsite contact, arrange access to included rooms and exterior work zones, and address only the obstacles directly affecting the glass. A storefront, an occupied office, and a multi-story campus will not need the same preparations.
Use the written scope as the reference. If access or an existing condition needs separate attention, identify it before the visit. Apply only the steps that fit the property and the planned method.
Confirm Exactly Which Windows Are Included
Identify the buildings, elevations, floors, and glass areas in the approved work. Exterior storefront panes, lobby and entry doors, upper-level windows, interior partitions, and common-area glass may be separate parts of a property. An exterior-only assignment does not automatically include the interior face of the same windows. Likewise, a lobby may be included while tenant suites are not.
“All windows” can mean different things to a manager, tenant, and crew. Review marked photos or plans where boundaries are unclear. Eastside’s commercial window cleaning service covers different buildings and access methods, but the approved scope determines the glass scheduled for this visit.
Confirm Interior Access Before the Crew Arrives
If interior glass is included, check whether the crew can reach the relevant offices, conference rooms, tenant suites, restricted departments, and shared spaces during the approved hours. A locked room may require a key, badge, escort, or an available tenant representative under the property’s own security procedures. Coordinate those arrangements with the people authorized to grant access.
List included spaces that cannot be opened at the planned time. Without arranged access, those windows may be skipped or rescheduled. Confirm check-in requirements; access to a common area does not grant access to every suite.
What Needs to Be Moved Away From the Windows?
Focus on the immediate work area. Displays, plants, fragile objects, paperwork, and electronics directly against included glass may obstruct access or be vulnerable while nearby work is performed. Furniture needs attention only where it actually blocks a reasonable approach to the window. A clear route to the relevant area also matters.
There is no standard need to empty an office. Move only items that prevent access or need protection nearby. Flag fixed counters or equipment that cannot be moved before service.
How Should Blinds, Shades, and Window Coverings Be Handled?
Where an interior window is included, a lowered blind, closed shade, or other covering may prevent access to the glass. Property staff or occupants can open or raise coverings when appropriate and when they can be operated normally. The need varies with the window design and the side being cleaned; exterior-only work may require no interior preparation at all.
Flag delicate, jammed, or damaged coverings. Do not force them or assume the crew will repair them. The property can assess another route to the glass or note the window as inaccessible.
Are Screens, Tracks, Frames, and Sills Included?
Glass, screens, tracks, frames, sills, and exterior ledges are different scope items. Some may be included on a particular assignment; none should be assumed from the words “window cleaning” alone. Confirm which details are listed, whether screens must be removed, and whether an inaccessible or damaged screen affects the planned work.
These boundaries belong in the written commercial window cleaning proposal. Resolve missing items before service instead of treating them as automatic. Have the responsible contact confirm any scope change.
Plan Around Tenants, Employees, and Customers
Occupied offices, storefronts, medical spaces, and lobbies can remain active during window cleaning, but the work may affect desks beside glass, entrances, meetings, customer-facing displays, or shared routes. Confirm the approved hours and which spaces must stay usable. Where appropriate, let affected tenants or departments know when interior access or a temporary exterior work area is expected.
Keep notices specific to affected areas. Exterior-only work may differ from work inside multiple suites. For broader routes and deliveries, see planning work around an occupied commercial property. Here, confirm that scheduled glass can be reached.
Confirm Exterior Access and Parking
Walk the likely approach to exterior glass. Depending on the agreed method, parked vehicles, loading activity, locked gates, courtyards, landscaping, setbacks, or equipment routes may affect access. Ask which spaces or paths need to be available during the approved work window and who can arrange them. Water access should be confirmed if the planned method calls for an onsite connection.
Not every project uses a lift or requires vehicle moves. If a section cannot be reached as planned, tell the contractor before arrival so the sequence or scope can be reviewed.
Prepare for Lift or High-Access Window Cleaning
When the approved access plan involves a lift or another high-access method, the property may need to coordinate the equipment route, staging space, gates, parking clearance, approved hours, and activity below the work area. Confirm which entrances, vehicle lanes, or pedestrian paths must remain open. A building engineer or other property contact can identify site restrictions and the person authorized to coordinate temporary access.
This is property preparation, not an instruction to operate equipment. The contractor’s access plan and the site’s requirements determine the method and work-zone controls. Avoid promising a staging area or a clear route until the relevant property contact has checked what is actually available.
Confirm the Onsite Contact
Name one available contact for the scheduled window work, with a practical way to reach that person during the approved hours. The contact may need to unlock a room, answer a scope question, resolve an unexpected access conflict, coordinate with a tenant, or direct the crew to the right building or elevation. The role can be filled by whoever has the appropriate property authority; it does not require a particular job title.
For multi-building or managed properties, share the building names, access notes, and tenant contacts before service. A property management cleaning services plan can coordinate multiple sites or recurring visits, while the day-of-service contact still needs to know which areas are included on this particular visit.
Identify Existing Glass Conditions Before Service
Point out visible hard-water mineral deposits, scratches, etched glass, haze between panes, paint, construction debris, stickers or adhesive, and damaged screens or frames. Photos and locations can help the property and contractor agree on what existed before cleaning. Note whether the issue is ordinary surface soil or something that may require evaluation beyond routine service.
Routine window cleaning can remove ordinary dirt without making damaged glass new. Mineral deposits may require separate hard-water stain removal testing and scope; bonded construction material can also require a separate assessment. Cleaning the accessible faces will not remove haze trapped between panes by a failed seal, repair scratches or frames, or reverse permanent etching. Raise these conditions before the visit so the expected result stays realistic.
Should Window Cleaning Be Coordinated With Other Exterior Work?
Ask whether building washing, pressure washing, construction, painting, facade work, or landscaping and irrigation activity is scheduled near the same glass. Where practical, dirt-producing work may be completed before final exterior window cleaning. For example, washing an elevation after its windows are finished may affect the appearance of the newly cleaned glass.
Sequence is site-specific. Access, weather, tenant hours, and the approved scope may make another order more workable. Share the other work dates and affected elevations with the onsite contact and contractor rather than assuming every exterior service must happen on the same visit. For maintenance planning over time, the separate guide to commercial window cleaning frequency addresses service intervals; this checklist addresses readiness for a scheduled visit.
Commercial Window Cleaning Preparation Checklist
Use the items that apply to the approved work:
- Confirm the included buildings, elevations, and glass areas.
- Confirm whether each area is interior, exterior, or both.
- Arrange access to included locked or restricted rooms, with escorts if required.
- Name the onsite contact and confirm approved work hours.
- Move only items that block access or are vulnerable immediately beside included glass.
- Open usable blinds or shades where they prevent access to included interior glass.
- Check whether screens, tracks, frames, sills, and ledges are in the scope.
- Confirm parking, gates, equipment routes, staging, or water access if the method requires them.
- Coordinate notices with affected tenants or departments where appropriate.
- Flag hard-water deposits, debris, damaged components, and other existing conditions.
For a larger property, attach room numbers, elevation labels, or a marked plan. Keep the preparation list aligned with the actual scope rather than sending the same instructions to every occupant.
Frequently Asked Questions
Do office employees need to leave during window cleaning?
Usually not automatically. It depends on which windows are included, the work area, and the property’s operating needs. Some desks or rooms may need temporary access while the rest of the office remains in use.
Does furniture need to be moved?
Only where it prevents reasonable access or creates an issue in the immediate work area. Clear the specific window area; do not assume every office must be rearranged.
Should blinds be raised before window cleaning?
If they block included interior glass and can be operated normally, opening them may help. Flag damaged or stuck coverings rather than forcing them.
Do parked cars need to be moved?
Only when the planned exterior access or work zone requires clearance. Confirm affected spaces and the timing with the property contact.
Can window cleaners enter locked offices?
Interior access must be arranged by the property when those offices are included. Confirm keys, badges, escorts, or tenant availability before the visit.
Are window tracks and screens automatically cleaned?
No. Confirm tracks, screens, and related details in the written scope before service.
Can hard-water stains be removed during normal window cleaning?
Mineral deposits can require a separate evaluation, test, and restoration scope. Routine cleaning should not be assumed to remove etched or bonded conditions.
