Power Washing a Concrete Driveway in Kitchener: What Affects the Final Price?

Power washing and pressure washing are two names for the same job, and on a concrete driveway the final price follows four things: how big the surface is, what is on it, how the site works and what you ask for on top. Below: how to measure your driveway, how each factor moves a quote and what a clear written quote lists.

What the published starting price means

D&D publishes pressure washing from $350 for typical Kitchener-Waterloo homes. It is a starting point for the service, not a rate per square foot, and there is no fixed price for "a driveway". Two slabs of the same size can differ in every way that costs time, which is why the final figure is set from photos or a look at the property and confirmed in writing before work begins.

Measure your driveway in five minutes

1. Measure the length and width of the main slab in metres. Split an L-shape or a flared apron into rectangles and add them up.
2. Add the walkway, the front steps and any garage apron as separate lines.
3. Multiply length by width for each section. For example, a slab 6 metres wide and 10 metres long is 60 square metres.
4. Photograph the whole driveway from the street, then take close-ups of stains, cracks and any green or black patches.

Send the measurements and photos with your request. It gives the estimator something real to price, and it stops a rough guess from becoming your final number.

What is on the concrete matters as much as how much

• Light dust and pollen are the baseline, and a surface cleaner covers them quickly.
• Algae, moss and green film need a cleaner and dwell time before the rinse.
• Oil and grease need a degreaser, extra dwell and sometimes a second round. Old stains may only lighten.
• Rust marks need a specialty product and care, since the wrong one can etch.
• Tire marks and rubber mean hand work and more time near the garage.
• Brown leaf stains take extra passes, and sometimes a brightening product.
• Salt scaling and cracks call for a gentler method, lower pressure and more care around weak areas.
• Weeds and grass in cracks come out by hand first, because a jet only spreads the mess.

Surface finish counts as well. A smooth slab rinses fast, while a coarse broom finish, stamped concrete or exposed aggregate hides dirt in its texture and takes longer to clean thoroughly.

Site factors that change the work

• Slope and drainage. Rinse water runs downhill. A driveway that falls towards the street or the garage needs a plan for where the water goes.
• Water supply. A working tap close to the driveway keeps things simple. A long hose run or a low-flow tap slows the job.
• Access and vehicles. Parked cars, a tight garage door or a narrow side gate mean moving things or working around them.
• Edges and plants. Beds beside the slab need protecting, and grass edges need care.
• Existing sealer. A sealed slab needs a gentler approach than bare concrete, and a failing sealer can peel during a wash.
• Method. A surface cleaner on the flat area is quicker and more even than a hand wand, and the edges and steps are finished by hand.

What a clear written quote lists

• Each area included: main slab, apron, walkway and steps.
• The method for the flat areas and for the edges and steps.
• Which stain treatments are included, and which are extra. Nobody can promise that an old oil stain will disappear entirely.
• What is left out, such as sealing, crack repair, weed control and rust removal.
• How plants are protected and where rinse water goes. The runoff should avoid the street and storm drains.
• Proof of insurance, such as D&D's $2 million in general liability cover.
• What happens if rain interrupts the work.

Comparing quotes line by line beats comparing totals. For the pattern across other surfaces, see pressure washing cost in Ontario, and the pricing page lists all the published starting prices.

Ways to keep the price sensible

• Sweep loose leaves and grit, and move cars and bins before the crew arrives.
• Show the crew the outdoor tap.
• Ask for the walkway and steps as their own lines, so you can decide about each.
• Deal with weeds yourself, and mention stains and cracks up front.
• Wash before growth thickens, since a light film is quicker to clear than a coated slab.
