Writing an Exterior Maintenance Contract Surface by Surface

By the fourth scheduled visit, the walk around a building looks nothing like the walk on day one. The north elevation that was streaked dark with algae now shows only a faint tint along the base where the sprinklers reach. The lower glass carries a light scatter of water spots that comes off in a single pass instead of the hazy mineral rings that needed treatment the first time. That gradual shift, from restoring a building to simply keeping it, is what an exterior maintenance contract is meant to buy, and it relies on an agreement that says exactly what happens to each surface and when.

Glass: Cadence, Water and Which Side Counts

Windows set the rhythm of most programs. For the majority of commercial buildings, cleaning them quarterly, or at least semi-annually, is the right baseline. Quarterly suits Class A offices, medical buildings, hotels and anything where the glass is the face of the property, while semi-annual often works for industrial sites with modest glazing.

A window cleaning contract should name the elevations, say whether it covers exterior glass only or both faces, and list frames, sills and storefront doors explicitly. Doors and vestibules at the entrance are the usual blind spot, so decide whether they belong to this agreement or the janitorial one. Specify the water as well. Our commercial window cleaning crews finish with 100% purified deionized water, which dries without spots, and any provider should be able to tell you what theirs uses.

Add a line for ground-floor touch-ups if your storefronts or entries need attention between full visits, priced separately so it can be dropped or increased without reopening the rest of the contract.

Facade: Interval, Method and the Elevations That Need More

Facade soft washing works on a longer cycle, usually every one to three years depending on material, shade and nearby traffic, with most commercial properties settling on annual or every-other-year washing. The agreement should list each elevation and its finish (stucco, EIFS, painted panels, brick, stone, metal) and state that it will be soft washed at low pressure with curated solutions suited to that material.

Some walls earn their own line. A shaded north face that never fully dries, a wall beside a highway or an elevation hit by irrigation will soil faster, and writing a shorter interval for that one elevation is far cheaper than stepping up visits across every wall. When the facade is due, the contract should time it just ahead of a window visit so grime off the walls does not land on fresh glass.

Roof and Solar: Cleaned When the Evidence Says So

Roofs and solar arrays rarely need a calendar slot. They are cleaned when debris, organic growth or performance data says they should be, so the agreement should say who decides and on what evidence. For arrays, that is usually the owner's monitoring data showing output dropping against expected levels.

Name each roof section and its type (TPO, EPDM, standing-seam metal, tile) and require that the cleaning method keeps foot traffic off the membrane, which is why our roof and solar cleaning is done from the air. Make it clear that any damage found during cleaning is reported to you and passed to your roofer, and that repairs are outside the cleaning scope.

Flatwork and Parking: Traffic Sets the Schedule

A pressure washing contract for walks, drives, entries and parking structures should be organized by area and by traffic. Main entrances, loading docks and dumpster pads usually need a shorter cycle than perimeter walks, and parking garages often need their own access plan around tenant hours.

Separate routine washing from specialty work. Rust, graffiti, oil staining and heavy degreasing are typically priced on their own, and the agreement should say how they are approved before anyone does them. Spell out where wash water goes, too, particularly around storm inlets and loading areas where grease and oil are involved.

Entrances, Tenants and Access Windows

Every recurring agreement needs a page about people. Record working hours, tenant-sensitive periods, delivery times and the areas that must stay open during service. Agree who sends tenant notices, how much lead time your team gets before each visit and who books the dates.

Flexible operating hours make a big difference on occupied buildings. Drone work also helps here, since crews stay on the ground, no lifts sit on the landscaping and walkways outside the active zone remain usable, but the contract should still say where safety perimeters will be set and how pedestrians are routed around them.

Terms That Apply to the Whole Site

A few clauses cover every surface at once, and they are where most disputes start.

Safety and insurance come first. Commercial drone flights under the FAA's Part 107 rules require the pilot to hold a Remote Pilot Certificate, so ask any provider for copies alongside proof of insurance and crew safety training. Our pilots are Part 107 certified and our crew holds OSHA 30 General Industry cards. Have your risk adviser set the insurance limits and endorsements.

Water and runoff deserve a clause of their own: where water comes from, who provides access to it, how wash water is handled and who keeps disposal records. Some properties need every drop captured and removed, and the contract should say whether yours is one of them.

Weather needs a fair rule. Rain, lightning and high wind stop exterior work, and wind grounds drones before it stops a ground crew. Agree who calls a delay, how quickly the visit is rebooked and how a part-finished visit is handled, so nobody is pushed to work in unsafe conditions to hit a date.

Finally, read the commercial terms closely: start date, renewal and any auto-renewal notice period, termination for convenience, when and how prices can change, how out-of-scope work is approved, and a requirement to document pre-existing damage before the first visit. For portfolios, a master agreement with a schedule per site is easier to run than a stack of separate contracts. Recurring schedules and bundled services usually earn better rates as well. Our checklist for choosing an exterior cleaning provider covers the questions to ask before you sign, and our exterior cleaning services page lists everything a program can include.

The difference between that first walk around the building and the fourth one comes from the paperwork as much as the cleaning. When each surface has its own line, its own interval and its own rules for access and water, the crew arrives knowing the building and the north wall never gets the chance to turn black again.

Frequently Asked Questions

Can a recurring program begin with a deep clean?

Yes, and it often should. The first visit brings the building back from its current condition and later visits maintain it. Ask for that initial restoration to be priced separately so you can see what the ongoing program actually costs.

What happens to the agreement if the property is sold?

The assignment clause decides, so read it before a sale is on the table. Check whether the agreement can pass to a new owner or manager, what consent is needed and how billing transfers, so service does not lapse during the handover.

Can service intervals change after the contract is signed?

A good agreement includes a review point where intervals can be adjusted based on what each visit has shown. If one elevation soils faster than expected, its frequency can go up without touching the rest of the building.

Should the contract ask for the same crew on every visit?

Asking for a named crew can be hard for any provider to guarantee, but you can require a written site file that travels with whoever arrives: water connections, access points, exclusions, tenant rules and problem areas. That file does most of what a familiar crew would do.

Who should approve extra work found during a scheduled visit?

Name one person, or a role, who can approve out-of-scope work in writing, and set a threshold above which a written change order is required. That stops small additions from turning into surprise invoices and keeps crews from waiting on site for a decision.

Is a maintenance agreement worth it for a single small building?

Often, yes. Even a small property benefits from a fixed schedule, because buildup removed on a regular cycle takes less time and gentler treatment than the same buildup left for two or three years. The paperwork can be short, as long as scope and intervals are clear.
