Driveway Sealing in Kitchener-Waterloo & Cambridge
Professional asphalt and concrete sealing that locks out moisture, UV rays, and salt damage — restoring your driveway's original colour and finish.
Driveway sealing (also called sealcoating) is the application of a protective coating to asphalt or concrete driveways to prevent damage from UV oxidation, water infiltration, oil and fuel spills, and Ontario's freeze-thaw cycles. A properly sealed driveway resists cracking, maintains its dark appearance, and can last 20 to 30 years with regular maintenance. D&D Home Services provides professional asphalt and concrete sealing throughout Kitchener, Waterloo, Cambridge, and Guelph, starting from $179.
Why Seal Your Driveway?
Canadian weather is brutal on asphalt. UV rays, freeze-thaw cycles, road salt, and automotive fluids break down the binder in your asphalt, causing fading, cracking, and crumbling. Professional sealcoating creates a protective barrier that extends your driveway's life by years.
Our premium coal-tar emulsion sealant is applied in two coats for maximum protection. It waterproofs the surface, resists oil and gas spills, and restores that deep, rich black colour.

The True Cost of an Unsealed Driveway in Ontario's Climate
Kitchener-Waterloo experiences 40 to 60 freeze-thaw cycles annually. Each cycle expands water trapped in driveway cracks by approximately 9% — the volumetric expansion rate of freezing water — widening every hairline crack with each passing winter. Road salt compounds the damage: sodium chloride breaks down the asphalt binder faster than freeze-thaw alone, causing surface ravelling and crumbling within 5 to 10 years on an unsealed driveway. An unsealed asphalt driveway in Ontario typically deteriorates from minor surface cracking to structural failure requiring full replacement within 10 to 15 years. Professional sealcoating every 2 to 3 years costs $179 to $500 — versus asphalt resurfacing at $3,000 to $8,000, or full driveway replacement at $5,000 to $15,000. Sealing is the lowest-cost maintenance decision a homeowner can make for long-term driveway protection.
How We Seal Your Driveway
Clean & Prep
Power washing to remove all dirt, debris, oil stains, and loose material.
Crack Repair
Hot rubberized crack filler is applied to any cracks wider than a quarter inch.
First Coat
Premium sealant is applied evenly across the entire surface.
Second Coat
After drying, a second coat is applied in the opposite direction for complete coverage.
Every 2–3 years is ideal for most asphalt driveways in Kitchener-Waterloo. Our region experiences 40–60 freeze-thaw cycles per winter — water enters micro-cracks, expands up to 9% when frozen, and widens them into costly repairs. An unsealed driveway typically deteriorates 3× faster, turning a $179–$500 sealing job into a $8,000–$15,000 replacement. High-traffic driveways or those with heavy road-salt exposure may benefit from annual sealing.
Walk on it after 24 hours, drive on it after 48 hours. We require temperatures above 10°C for optimal curing.
Our sealcoating is for asphalt driveways. For interlocking or concrete, we recommend our pressure washing service.
