Interlock & Paver Sealing in Kitchener-Waterloo

Clean, re-sand and seal your interlock

D&D Home Services cleans, re-sands and seals interlocking pavers across Kitchener, Waterloo, Cambridge and Guelph. We clean the surface and the joints, refill the joints with polymeric sand and apply a sealer that suits the look you want, so driveways, patios and walkways keep their colour and resist weeds, stains and road salt.

What's included

• Surface cleaning: dirt, algae, moss and most organic staining lifted with surface cleaners and a controlled rinse.
• Joint cleanout: weeds and old, washed-out sand removed from the joints.
• Polymeric sand re-sanding: joints refilled, compacted and misted so the sand firms up and resists washout, weeds and ants.
• Sealing: a sealer matched to your pavers and the finish you choose, from a natural look to a richer wet look.
• Problem spots: white efflorescence haze, rust and oil stains are assessed before sealing, and we tell you what can and cannot be lifted.

Natural look or wet look?

Sealers change how pavers look, so the finish is your choice. We bring the options to the quote.

When to seal in Ontario

Sealing needs dry pavers and a few dry days, so we work from late spring to early fall, above the minimum temperature on the product label. New interlock is usually left to weather for a season first, so any efflorescence can work its way out before it gets sealed in. Sealing before winter means the joints and surface face road salt and freeze-thaw already protected.

How often to reseal

Every few years for most homes, depending on the sealer, traffic, sun and salt. It is time when water stops beading, the colour looks washed out, or the joints start losing sand. Sealing too often builds up a cloudy, slippery film, so we check what is already on the surface before adding more.

What affects the price

The square footage, how much cleaning and stain work the surface needs, whether the joints need full re-sanding, the finish you choose, and steps, borders or tight areas.
