Pressure washing in Calgary: hiring and planning
Pressure washing in Calgary starts with checking whether the proposed water supply and use comply with restrictions, then agreeing on wash-water collection and disposal. Choose a contractor who explains the method for each surface and includes runoff handling in the quote. Calgary prohibits wastewater discharge into stormwater. The City's page reported no active outdoor restrictions when checked on October 13, 2026; recheck before work begins. [1] [2]
Define the job before comparing quotes
Send bidders photos of the work area and close-ups of stains, damaged finishes, cracks and joints. Name each surface you want cleaned and separate optional work from the main job. Include approximate dimensions, building height, gate access and the location of your outdoor tap.
Have the contractor explain the proposed pressure, cleaning products and rinsing method for each material. Request a small test area if you have concerns about the finish. For siding, painted wood, roofing or upper-storey work, ask the bidder to consult the manufacturer's cleaning instructions and explain access arrangements before you approve the method.
Agree on the result you expect. Distinguish general cleaning from treatment of oil, rust or other stains, and have the bidder identify marks they exclude from the promised result. Photograph existing damage together before work starts.
Include runoff handling in the quote
Calgary's mobile power-washing guidance requires businesses to follow its wastewater and stormwater bylaws. The City prohibits wastewater discharge into stormwater and requires filter screens at water release points to capture solids. Have the contractor identify nearby storm drains and low points where wash water will collect. [1]
Require an explanation of both recovery and disposal. The City lists vacuum systems, wastewater recovery systems and absorbents as collection equipment. A filter screen does not authorize stormwater discharge. Confirm what equipment the crew will bring and where they will take the recovered water. [1]
Before approving disposal into a sink or floor drain, ask how the contractor will meet the City's wastewater conditions. Calgary permits disposal through drains connected to the wastewater system only when the water contains no Schedule A prohibited substances and meets Schedule B and C concentration limits. Have the contractor account for the cleaning products and contaminants from your job. [1]
Check water supply, restrictions and weather
Check the City's restriction status when booking and before the crew arrives. The City's page reported no active outdoor restrictions when checked on October 13, 2026. Its restriction tables apply to outdoor use of Calgary Water Utility water: driveway, sidewalk and walkway washing is prohibited in Stages 1 through 4 unless health and safety regulations require it. [2]
For City-supplied water, the tables allow exterior building and window washing in Stages 1 through 3 and prohibit it in Stage 4. The City also allows businesses using non-potable sources to continue. Under Stage 4, businesses may use potable water from bulk stations for outdoor surface washing required for health and safety. If a contractor proposes alternative water or an exception, confirm the source and specific use with the City before approving work. [2]
Under the regular lawn and landscape schedule, the City allows window washing and pressure washing decks, fences and siding any day and time. Temporary restrictions override those permissions. You do not need to match a routine siding appointment to your lawn-watering day, but you do need to recheck restriction status. [3]
Agree on a weather cancellation policy and have the contractor check overnight temperatures alongside daytime conditions. Calgary Airport's 1991–2020 normal daily minimum temperatures were below zero in April and October. The chart offers seasonal context; historical averages cannot establish whether your appointment will suit the work. [4]
Compare the total and prepare your property
Request a written total with separate entries for optional surfaces and stain treatments. Confirm whether it includes water supply, recovery equipment, wastewater transport and disposal, cleanup and applicable taxes. Review minimum charges, deposits, cancellation terms and how you will approve extra work. Set your budget using quotes for the same site and scope.
Request proof of liability insurance and clarify responsibility for accidental damage. For shared exterior areas, get the property manager's approval and agree on access, parking and resident notices. Arrange who will move furniture and planters, close windows and keep children and pets away from the work area.
At handover, walk through the cleaned areas with the contractor. Compare the result with your scope and starting photos, discuss remaining stains and ask when you can use the surfaces again. Keep written changes with the quote and invoice.

Local details that affect your job
Separate driveway and siding prices
During Stages 1 through 3, Calgary's tables permit exterior building washing with City-supplied water but prohibit routine driveway washing with that supply. The driveway exception covers work required by health and safety regulations. Businesses may continue with non-potable sources. Request separate prices for a combined job and confirm any alternative supply or exception with the City before deciding which work can proceed. [2]
Confirm authorization for landfill disposal
For its zero-discharge option, the City directs cleaning waste to the Shephard Landfill Industrial Car Wash Disposal facility and requires an industrial permit application for wastewater disposal there. If your contractor proposes that route, have them confirm authorization and include hauling and disposal in the quote. [1]
Book outside lawn-watering days
The City's lawn and landscape schedule took effect April 29, 2026. Under that regular schedule, you can arrange deck, fence or siding washing any day and time without matching your address's lawn-watering days. Check temporary restrictions before proceeding because they override the schedule. [3]

Frequently Asked Questions
Can a contractor let driveway wash water run into a street drain?
Calgary prohibits wastewater discharge into stormwater. Have the contractor identify drain locations, explain water recovery and name the disposal route before accepting the quote. [1]
Do I have to book siding washing on my lawn-watering day?
Under the regular lawn and landscape schedule, you can wash siding, decks and fences any day and time. Temporary restrictions override that schedule, so check their status before the appointment. [3]
Can routine driveway washing proceed during Stage 1 restrictions?
The City's Stage 1 table prohibits driveway washing with City-supplied water unless health and safety regulations require it. Its guidance permits businesses using non-potable sources to continue. Confirm the contractor's proposed source and use with the City; otherwise, arrange to reschedule routine City-water cleaning. [2]
How should I compare pressure-washing prices?
Give bidders the same photos, dimensions and requested surfaces. Compare written totals covering preparation, stain treatment, water supply, runoff recovery, disposal and cleanup. Have each contractor list exclusions and optional work so you can assess the scope alongside the price.
