Interlocking stone cleaning in Toronto is three jobs, not one: clean the pavers, replace the joint sand and seal the surface. Done separately, they leave joints open between visits. Done together on the same day, they lock the pavers, stop weeds and protect the surface from the next winter. That is how our interlock crews work.

## Why Does Toronto Interlock Fail So Fast?

Interlock depends on the sand in its joints. That sand transfers load between pavers and keeps water and weeds out. Toronto winters attack it from every side. Water gets into the joints, freezes, expands and pushes the sand out. Road salt leaves white efflorescence on the paver faces. Spring melt washes loose sand away. By May, many driveways in Leaside, Forest Hill and Angus Glen have half-empty joints, weeds and ant hills, and pavers that rock when you step on them.

Most DIY cleaning makes it worse. A rental pressure washer with a narrow tip blasts out what is left of the sand and gouges the paver faces. Without fresh polymeric sand and sealer right after, the surface is more exposed than before it was cleaned.

## Cleaning Interlock Without Emptying the Joints

Our cleaning stage uses a rotary surface cleaner, which spins two nozzles inside a hood a fixed distance above the pavers. It cleans the face evenly, without stripes, and without driving water into the bedding sand. Edges, steps and borders get a 25-degree nozzle held at a controlled distance, and stubborn spots get a turbo tip only where the paver can take it.

Where white efflorescence is present, we apply an efflorescence neutralizer before washing. Oil and rust stains get spot treatment. The goal is a clean, uniform paver face with joints ready to accept new sand.

| Step | Rental pressure washer (DIY) | Our same-day process |
| --- | --- | --- |
| Paver faces | Narrow tip gouges faces and leaves stripes | Rotary surface cleaner cleans evenly at a fixed distance |
| Joint sand | Blasts out what is left of the sand | Joints refilled with compacted, activated polymeric sand |
| Efflorescence and stains | Rinsed, not treated | Efflorescence neutralizer and spot treatment before washing |
| Protection afterwards | Surface more exposed than before | Sealed the same day, wet-look or natural |

## Polymeric Re-Sanding

Once the pavers are dry enough, we sweep 

polymeric sand

[/blog/interlock-polymeric-sand-pressure-specs-reseal/ →](/blog/interlock-polymeric-sand-pressure-specs-reseal/)

 into every joint. Polymeric sand, from suppliers such as Techniseal, contains binders that harden when misted with water. We compact the sand into the joints, top up any low spots, blow excess off the paver faces so it does not haze, and then activate it with a fine mist.

The result is joints that stay put through rain, resist weeds and ants, and hold the pavers firmly together. It is the single most important step for interlock longevity in a freeze-thaw climate.

## Sealing (Wet-Look or Natural)

Sealing protects the paver surface from staining, slows colour fade and helps the polymeric sand last. You choose the look:

| Sealer type | Finish | Best for |
| --- | --- | --- |
| Water-based penetrating sealer | Natural, matte | Homeowners who want the original look, breathable protection |
| Solvent acrylic wet-look sealer | Deepened colour, light sheen | Driveways and patios where colour pop matters |

We apply sealer with a low-pressure sprayer and back-roll where needed, rope the area off and give you cure times in writing.

## When Does Interlock Need Cleaning and Resealing?

-   Joint sand is low or washing out after winter
-   Weeds or ants are coming up between pavers
-   White efflorescence or grey film covers the surface
-   Colour has faded and water no longer beads
-   You are preparing to list, or you have just bought a home with tired interlock

## How Much Does Interlocking Stone Cleaning Cost in Toronto?

### Pricing

Full service, meaning clean, polymeric re-sand and seal, runs **$3.50-$5.50 per square foot** depending on condition, with a $450 minimum. A typical residential driveway or patio lands between **$450 and $1,200**.

-   **Light ($3.50/sq ft):** grime and film, joints mostly intact
-   **Moderate ($4.50/sq ft):** weeds and partial sand loss
-   **Heavy ($5.50/sq ft):** empty joints, efflorescence, old sealer to deal with

## Interlock vs Concrete Driveway Cleaning

If your driveway is poured concrete rather than pavers, the job is different: hot water for road salt and a surface cleaner, with optional sealing. See 

driveway cleaning

[/driveway-cleaning-toronto/ →](/driveway-cleaning-toronto/)

 for that service, or 

pressure washing

[/pressure-washing-toronto/ →](/pressure-washing-toronto/)

 for mixed properties.

## Common Interlock Problems We Solve

### Weeds and ants between pavers

Weeds and ant hills are a sign the joints have lost sand. Cleaning them out and replacing the sand with polymeric sand removes the space they need.

### Rocking or sunken pavers

Loose pavers usually mean the joints are empty and the pavers can shift. Re-sanding tightens most areas. Pavers that have sunk because the base has settled need lifting and re-levelling, which we flag at the quote stage.

### White efflorescence

Salt and minerals rising through the pavers leave a white bloom. A neutralizer before washing clears it, and sealing slows its return.

### Polymeric haze

When polymeric sand is installed on damp pavers or not blown off properly, it leaves a cloudy film. We clean it off, then install new sand on dry pavers.

### Peeling or yellowed old sealer

Old film-forming sealers can peel and yellow. They need stripping before a fresh coat, which falls into the heavy condition tier.

## What to Expect on the Day

The crew arrives in the morning so there is time for every step. Pavers are cleaned first, then left to dry for a few hours while edges and steps are detailed. Polymeric sand goes in once the surface is dry, followed by activation with a fine mist and, once that has set, the sealer. The area is roped off and you receive cure times in writing. If rain moves in, we pause between steps rather than rushing sand or sealer onto wet pavers.

Case study

## A Recent Interlock Project

![Leaside interlock driveway after cleaning, polymeric re-sanding and sealing](/images/features/restored-interlock-paver-driveway-in-leaside-toron.webp)

Leaside

### Leaside Interlock Clean and Polymeric Reseal

Rig: rotary surface cleaner + polymeric sand + penetrating sealer

A Leaside family's interlock driveway had empty joints, weeds and a grey film after years of freeze-thaw and road salt. In one visit we cleaned the pavers with a rotary surface cleaner so joint sand came out evenly, swept in fresh polymeric sand, activated it, and applied a natural-finish penetrating sealer. The driveway was roped off for a day and back in use by the weekend.

## What Clients Say About Our Interlock Work

Real jobs, real prices, written quote first.

Andrew B.

Forest Hill

$840

> "Our interlock driveway had lost most of its joint sand after a rough winter and weeds were coming through. They cleaned it, swept in new polymeric sand and sealed it with a natural finish, all on the same day. They explained the cure time clearly and roped it off for us. A year later the joints are still tight and the weeds have not come back. The price matched the written quote to the dollar, and they left the street cleaner than they found it. Our neighbours on the next street have since booked them for their own interlock."

Interlock clean + polymeric reseal

Daniel R.

The Beaches

$340

> "We live under big trees near the boardwalk and our side walkway was green and slippery most of the year. They soft washed the moss instead of blasting it, then rinsed the patio stone and reset some of the joint sand. My kids stopped slipping. They also gave me a straight answer on how often to book it again, which was refreshing. Weekend booking made it easy."

Patio + shaded walkways

Sarah K.

Leaside

$180

> "Our single driveway had white salt lines every spring. The crew showed up on a Sunday, used hot water and a round surface cleaner, and it looked new in about an hour. Quote was in writing before they started. Exactly the price we were told. Already booked our spring visit."

1-car concrete driveway

Linda M.

Rosedale

$425

> "They cleared the salt stains in one visit. Mature maples drop sap every summer, this crew knew exactly which tip to use."

Driveway + walkway

Tom W.

Riverdale

$240

> "Grey cedar deck, about 300 square feet. They used low pressure and a wood cleaner so the boards did not get fuzzy like my DIY attempt last year. Dry by the next afternoon and ready for stain. Fair price, tidy crew, no surprises, and they rinsed the fence too."

## Interlock FAQs

### Can you clean and reseal interlock in the same visit?

Yes. We clean with a rotary surface cleaner, let the pavers dry enough, sweep in polymeric sand, activate it and apply sealer, usually all in one day. Full service runs about $3.50-$5.50 per sq ft, typically $450-$1,200 for a residential driveway or patio. Weather sets the exact timing, because sand and sealer need dry pavers and a dry forecast.

### Can pressure washing ruin interlock pavers?

Yes, if it is done with a narrow tip held close to the surface. That gouges the paver face and blasts the joint sand out, which leads to weeds, shifting and frost heave. We use a rotary surface cleaner and calibrated nozzles that clean the surface without digging into the joints.

### How often should interlock be resealed?

Most Toronto driveways and patios benefit from resealing every two to four years. Signs it is time include fading colour, joint sand washing out after winter, weeds returning and water no longer beading on the surface.

### What is polymeric sand and why does it matter?

Polymeric sand is joint sand mixed with binders that harden when misted with water. It locks pavers together, resists washout and makes it harder for weeds and ants to get established. After repeated freeze-thaw cycles it breaks down and needs replacing.

### How long before I can drive on resealed interlock?

Usually you can walk on it the next day and drive on it after 24-48 hours, depending on the sealer and temperature. We rope off the area and give you exact cure times in writing.

### Wet-look or natural sealer, which is better?

Wet-look solvent acrylic sealers deepen colour and add sheen. Water-based penetrating sealers keep a natural matte look and are more breathable. Both protect against staining and help hold the sand. We show you samples and recommend based on the paver and how you use the space.
