Detailed Description

Cracked or open joints in concrete can let in water, salt, and debris—causing damage over time. With our Concrete Joint Caulking service, we clean and prep the joints, removing any failing material before applying a high-performance flexible sealant. This sealant expands and contracts with temperature changes, extending the life of your Toronto & GTA driveway, walkway, or patio while keeping it looking clean and well-maintained.

Frequently Asked Questions

Why is it important to seal concrete joints?

In Toronto, water enters unsealed joints, freezes, and expands, causing the concrete to heave, crack, or spall. Sealing prevents this water intrusion and also stops unsightly weeds from growing in the gaps.

What material do you use?

We typically use commercial-grade polyurethane sealants. Unlike the rigid stuff found in hardware stores, this material remains flexible and rubbery for years, handling foot and vehicle traffic without cracking.

How long does it take to dry?

Self-leveling sealants usually form a skin within a few hours, but we recommend keeping cars off the driveway for at least 24 to 48 hours to ensure a full, durable cure.

Service Complexity Moderate

Why is a Technical Visit necessary?

Caulking concrete isn't just about filling a hole. If the joint is deep, simply filling it with sealant causes "three-sided adhesion," which leads to the caulk tearing when the concrete moves. Our Concrete Joint Caulking assessment involves measuring the joint depth to install a "backer rod" first. This ensures the sealant bonds only to the sides, acting like a rubber band that stretches safely without breaking.

Frequently Asked Questions

It’s a professional on-site assessment. A certified CNG Contracting technician inspects the work area, takes measurements and photos, checks access, safety, and any constraints (power, water, ventilation), and discusses your goals, style, and finishes. You’ll receive a detailed proposal with a clearly defined scope, timeline, and material options. Even if you choose not to proceed, you keep the written findings and recommendations.

We typically confirm within 2 business hours by email or phone with the earliest available time window. For urgent issues, we try to offer same day response when scheduling and scope allow. Larger jobs may require material lead times if so, we coordinate the earliest visit that avoids delays once on site.

After the assessment we define a clear scope of work (tasks, inclusions, timeline, and material assumptions). Your quote reflects that scope as a fixed price it won’t change unless you approve a scope change or we uncover a hidden condition that wasn’t visible during inspection (e.g., concealed rot). Any change is documented with photos and options before proceeding.

We protect floors and high-traffic areas, isolate dust where needed, and remove debris at the end of the day. We aim to minimize disruption to your routine. At handover, we complete a quality checklist and, when appropriate, share before-and-after photos for your records.

For services labeled “materials included”, standard consumables and parts are covered. For custom work (e.g., built-ins), we can price both CNG-supplied materials and client-supplied materials. We’ll specify makes, quantities, and compatibility to ensure durability and code compliance.

Yes. Rescheduling with at least 48 hours’ notice is free. Short-notice cancellations may incur a coordination fee. If weather or health/safety concerns arise, we prioritize safety and offer the closest new slot available.

We provide a 2-year workmanship warranty. If something isn’t right, we’ll diagnose and correct it promptly. For support, email handyman-pro@cngcontracting.com
or call (647) 669-7346; we’ll schedule a follow-up, document findings, and complete the corrective work.

Yes. We offer maintenance plans, priority response, standardized task catalogs, and consolidated invoicing for offices, retail, and multi-unit buildings. Ask about SLAs and reporting if you manage multiple locations.

Absolutely. We design and install grab bars, threshold ramps, wider doorways, anti-slip flooring, walk-in shower rails, and more. We assess reach, transfer zones, and path-of-travel to reduce fall risk and increase independence. We’ll explain pros/cons, maintenance, and lifespan of each option.
