Frequently Asked Questions

Will this stop mice from entering?

Yes. Exclusion is the most effective long-term pest control. By physically sealing the entry points with rodent-resistant materials, we force them to look elsewhere for shelter.

Do you seal "weep holes" in brick?

We do, but carefully. Weep holes are necessary for your walls to breathe. We install specialized stainless steel covers or mesh that blocks mice and insects but still allows air and moisture to escape.

Does this help with cold drafts too?

Absolutely. The same gaps that let bugs in also let cold air in. Our sealing process significantly reduces drafts, helping you save on heating and cooling bills.

Requires inspection: Yes

Seasonal service: true

Estimated Time: 2 to 6 hours

Materials included: Not included (unless specified)

Warranty Period: 2 years

Service Complexity Moderate

Why is a Technical Visit necessary?

Pests are persistent. A mouse can squeeze through a hole the size of a dime, and simple spray foam isn't enough because they can chew right through it. Our Pest-Proof Sealing assessment identifies overlooked entry points—like AC lines, gas pipes, and foundation cracks—and determines the right combination of materials (steel wool, copper mesh, and elastomeric sealant) to create a permanent barrier.

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. Our system assigns the nearest crew and accounts for travel to meet the agreed time window.
