Absolutely — professional concrete sealing is one of the most cost-effective ways to extend the life of your surfaces. Here’s how sealing helps:

• Prevents water damage — stops moisture from penetrating and causing freeze-thaw cracking, especially important in London, Ontario winters
• Blocks oil and stain penetration — keeps surfaces cleaner and prevents permanent staining from vehicle leaks
• Reduces UV fading — protects colour from bleaching out in summer sun
• Prevents surface erosion — stops the concrete surface from breaking down over time

A properly maintained and regularly sealed concrete surface can last 25 to 30+ years — compared to 10 to 15 years for unsealed concrete in harsh Canadian climates.

Yes — sealing new concrete is highly recommended, but timing is important. New concrete must be allowed to fully cure before sealing. Here’s the general guideline for London, Ontario homeowners:

• Minimum curing time — wait at least 28 days after a new concrete pour before applying sealant
• Why seal new concrete — fresh concrete is porous and highly vulnerable to staining, moisture, and freeze-thaw damage in its first winter
• Best time to seal new concrete — late spring or early fall when temperatures are consistently above 10°C

Sealing new concrete right after the curing period gives it maximum protection from day one and significantly reduces maintenance costs over the years. Our team handles both new installations and existing concrete sealing across London, St. Thomas, and Woodstock.

Proper preparation is the most critical step in any concrete sealing job — a poorly prepared surface will cause the sealant to peel, bubble, or fail within months. Our preparation process includes:

• Deep cleaning — professional power washing to remove all dirt, oil stains, mold, algae, and old sealant residue
• Crack repair — filling all cracks and joints with professional-grade filler that flexes with seasonal movement
• Stain treatment — applying degreaser to oil and grease spots to prevent bleed-through after sealing
• Surface dry time — ensuring the concrete is completely dry before sealant application — typically 24 to 48 hours after cleaning
• Surface inspection — checking for any structural issues that need to be addressed before sealing begins

We never skip preparation steps — it’s the difference between a seal that lasts 2 to 3 years and one that fails in 6 months. All preparation is included in our service at no extra charge.
