Interlock Repair and Sealing in Oakville (2026): Prices and Driveway Apron Rules

Oakville has a lot of high-end interlock and natural stone: wide driveways in Glen Abbey and Joshua Creek, tumbled pavers in Old Oakville, and big backyard patios. Much of it was sealed once at install and then left. Restoring it properly costs a fraction of replacing it. Here are the prices, the Town rules for the apron, and the mistakes that cost Oakville homeowners the most.

Larger Oakville driveways, often 800 to 1,200 sq ft with a walkway and porch landing, sit at about $1,000 to $3,000 for a full clean, re-sand and seal. Large-format slabs, permeable pavers and natural stone take longer than standard pavers and land at the upper end. Releveling is quoted per area after we lift a few pavers and check the base underneath.

Your driveway apron: Town land, your responsibility

The section of driveway between your property line and the road, the apron, sits on the Town's right of way. The Town's driveway permits procedure is clear about who looks after it:

• It is yours to maintain. All risk, responsibility and expense of an apron on the Town's right of way rest with the homeowner it serves.
• Interlock is allowed. Aprons in the urban area may be surfaced with asphalt, concrete or interlocking pavers, over a compacted granular base of at least 150 mm.
• Resurfacing needs no permit. Lifting and relaying, or replacing the surface of an existing apron without changing it, does not need a permit.
• Altering it does. Widening the driveway, adding a second entrance, making it circular or building curbs on the road allowance needs a Town driveway permit.
• If the Town or a utility digs it up, the disturbed part must be put back to its previous condition or better. The Town accepts that new material may not match old in colour.
• North Oakville is different. North of Dundas Street, residential aprons are concrete to Town standard, and only the developer, or the Town once the road is assumed, may install or change them.

In practice: if your interlock apron has sunk or heaved, we can relevel it under the same rules as the rest of the driveway. If a utility crew has just patched your apron with asphalt, contact them and the Town about reinstatement before paying anyone to fix it.

Cloudy, peeling or patchy sealer

The call we get most often in Oakville is about a driveway or patio that turned milky white, or is peeling in patches, a year or two after sealing. The usual causes:

• sealer applied to pavers that were still damp after washing;
• a glossy, solvent-based sealer laid on too thick;
• new coats layered on an old film until it can no longer breathe.

A haze from trapped moisture sometimes clears on its own over a hot summer. If it does not, the old sealer has to be stripped chemically, rinsed, left to dry fully, then resealed with a breathable matte or penetrating product. Stripping runs $1.80 to $3.60 per square foot, which is why getting the first seal right matters. Our guide on how to seal pavers covers the details.

White staining on newer interlock

Many Glen Abbey, River Oaks and north Oakville driveways go chalky white in their first year or two. That is efflorescence, natural salts in the concrete coming to the surface, not a defect. It usually fades with time and rain. If you want it gone sooner, it can be treated with an efflorescence cleaner at about $0.35 to $0.80 per square foot, but always before sealing, never after. See why pavers turn white.

Sunken spots and trip edges

On Oakville's clay soils, the usual problem spots are where downspouts run onto the pavers, where a garage floor drain or sump discharge empties on the driveway, along unrestrained lawn edges, and around big maple and oak roots in the older neighbourhoods. A few low pavers can be lifted, bedded and reset in a short visit. A rutted driveway with pavers rocking in the wheel paths has a base problem and needs rebuilding. Where tree roots are involved, the Town's private tree by-law still applies to the tree, so roots under the pavers are pruned with care, not cut out wholesale.

Natural stone and premium pavers

Natural flagstone, limestone and large-format slabs need a gentler clean than standard concrete pavers. High pressure can etch the surface or blow out the joints. We use lower pressure with surface cleaners, a stone-safe cleaner, and a penetrating sealer that does not change the look of the stone. Tumbled and antique-style pavers often have wider joints that take more polymeric sand. Mention the material when you ask for a quote.

When to book

Sealing and polymeric sand need dry weather and surface temperatures of about 10°C or more, which in Oakville means roughly May to early October. Releveling can go a little later into the fall, until the ground freezes. Over winter, shovel with a plastic blade and keep snowbanks off the driveway edges. Booking in late winter usually gets you on the schedule for May.
