How much does exterior pressure washing cost for a newly built home in Ottawa?

Quotes for exterior pressure washing on a newly built home in Ottawa can run roughly $300 to $1,500, depending on the size of the home, the number of exterior surfaces involved, and how much construction residue has built up. Treat that as perspective only — the way to know your price is to ask for itemized written quotes that list which surfaces are included, such as siding, foundation walls, walkways and the driveway.

New construction leaves behind a surprising amount of exterior grime. Mortar splatter on foundation walls, concrete dust on walkways, dried mud tracked by equipment, paint overspray, and general construction film can all build up on exterior surfaces during the building process. Clay-heavy mud that has dried onto concrete or siding often won't come off with a garden hose. Different surfaces need different pressure settings — concrete can take more than wood decking, and vinyl siding needs a gentle touch — so ask the crew what pressure and nozzle they plan to use on each surface.

Timing matters in Ottawa. Exterior pressure washing on a new build is usually best scheduled from late spring through early fall, when the weather is reliably warm. Pressure washing in cold weather risks freeze damage to surfaces and equipment, and water can seep into cracks and expand when temperatures drop overnight. If your new build wrapped up during the winter months, plan the exterior pressure wash for May or June once overnight frost risk has passed.

Several factors can push costs toward the higher end of the range. Homes with multiple storeys require specialized extension equipment or scaffolding. Large driveways and walkways add square footage to the job. If the builder left significant mortar or concrete residue on brick, a chemical pre-treatment may be needed before pressure washing, which adds to the total. Lots where heavy equipment has been running on clay soil for months can need more intensive driveway and walkway cleaning.

Get at least three itemized written quotes. Ask each company for proof of liability insurance and what it covers, and ask whether they have WSIB coverage or a clearance certificate. A crew that damages your new siding or mortar joints with overly aggressive pressure settings can create expensive repairs.
