Preventing water damage starts with proper sealing and expert slope management. With our Leak Sealing & Slope Adjustment service, we assess gutters, porches, and other exterior surfaces, sealing leaks and adjusting slopes to ensure water flows safely away from your Toronto & GTA home. This critical maintenance helps avoid standing water, wood rot, and long-term foundation damage. Our team handles the work efficiently, protecting your property and leaving the area clean. We complete every job precisely, so your drainage system functions properly from day one—friendly, professional, and done right the first time.

Frequently Asked Questions

Why is my gutter still leaking after I cleaned it?

Often, it isn't a clog but a failed seam or a "low spot" in the gutter run. If the hangers have loosened, the gutter sags, holding water that eventually eats through the sealant. We re-slope the trough and apply industrial-grade gutter sealer to the joints.

Can you fix water pooling on my concrete porch?

If the pooling is minor, we can apply specialized resurfacing compounds to create a subtle slope. For larger issues, we identify if soil settling is the cause and recommend the best sealing or leveling approach to protect your entrance.

Is slope adjustment permanent?

We use heavy-duty hidden hangers and masonry anchors to "lock" the new slope in place. While extreme soil shifting or heavy ice loads can affect it over years, our professional adjustments are designed for long-term stability.

Requires inspection: Yes

Estimated Time: 3 to 8 hours

Materials included: Not included (unless specified)

Warranty Period: 2 years

Service Complexity Moderate

Why is a Technical Visit necessary?

Water always follows the path of least resistance. If a porch or gutter has a "negative slope" (tilting toward the house), water will pool against the foundation, leading to basement leaks and structural rot. Simply sealing a leak won't fix the problem if the water is still standing. Our Leak Sealing & Slope Adjustment assessment uses precision levels to calculate the exact pitch required to redirect water flow, ensuring your home stays dry even during Toronto's heaviest rainstorms.

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.

We cover Toronto (all boroughs), Mississauga, Brampton, Hamilton, Oakville, Burlington, Vaughan, Richmond Hill, Markham, Oshawa, Milton, Guelph, Cambridge, Kitchener, Waterloo, London, Barrie, St. Catharines / Niagara and more.
