What is pressure washing + resanding?

Interlock surfaces collect dirt, moss, algae, and organic staining over the years. Joint sand erodes and weeds start pushing through. Pressure washing and resanding is the most effective way to restore the look and stability of your interlock without replacing anything. We use professional equipment calibrated for interlock to clean deeply without damaging the paver surface or displacing the base. After washing, we remove the old joint sand and replace it with fresh kiln-dried or polymeric sand, compacted into every joint for a tight, weed-resistant finish. The transformation is dramatic. Colour comes back, joints tighten up, and the surface looks clean and maintained again. We recommend doing this every two to three years depending on your level of traffic and tree cover.

Dramatic visual restoration

Professional cleaning removes staining, algae, and grime that makes interlock look old and neglected.

Tighter, more stable joints

Fresh polymeric or kiln-dried sand locks pavers together and reduces movement.

Reduces weed growth

Clean, properly filled joints give weed seeds far less room to establish.

Extends surface lifespan

Keeping joints full and pavers clean prevents accelerated wear and base erosion.

Our process

A clean finish starts with the steps you do not see. We build from the base up.

Step 1

Surface inspection

We check paver condition, joint depth, staining, and any areas that need extra attention before starting.

Step 2

Pressure washing

We wash the entire surface using professional equipment set for interlock, removing buildup without damaging pavers.

Step 3

Resanding and compaction

We sweep sand into all joints, compact it in, and ensure a full, tight finish across the surface.

FAQ

Common questions about pressure washing + resanding.

+Will pressure washing damage my pavers?

Not when it's done correctly. We adjust the pressure and use the right nozzle for your specific paver type so we clean thoroughly without etching the surface or blowing out the joint sand prematurely. DIY pressure washers set too high can definitely cause damage, which is why it's worth having it done professionally.

+Should I do polymeric sand after washing?

If your joints are in decent shape and the weather cooperates, polymeric sand is a great upgrade after a wash. It hardens in the joints, which means less weed growth and better paver stability compared to regular sand. We can assess the joint condition after washing and let you know if it makes sense for your situation.

+How long does it take?

Most pressure washing and resanding jobs are completed in a single day. A typical driveway takes around 3 to 5 hours including drying time between the wash and resanding. Larger areas or surfaces with heavy buildup might take a bit longer, but we'll give you an estimate upfront.

+Can you remove oil stains?

We can usually improve oil stains significantly, especially if they're relatively fresh. Older stains that have soaked deep into the paver are harder to fully remove, but pressure washing combined with targeted cleaning agents can make a noticeable difference. We'll be upfront about what to expect based on the condition of your surface.

+How often should I wash?

Most homeowners in Ottawa benefit from a wash every 2 to 3 years, though areas with a lot of shade or tree cover might need it more often since moisture and organic debris build up faster there. High-traffic driveways also tend to need more frequent attention than a backyard patio that gets lighter use.

+Will weeds come back?

Weeds can return over time since seeds blow in naturally, but proper resanding makes a big difference. Polymeric sand is the best option for keeping weeds out of the joints long term. Keeping nearby garden beds and vegetation trimmed also helps reduce the amount of organic material that ends up on your interlock.
