A small air drafts sealing job can turn into a bigger headache when loose parts, damaged surfaces, worn hardware, awkward access, or unfinished repair work are ignored. In Mississauga homes, including detached houses, townhouses, condos, and waterfront properties, gaps around windows, doors, tubs, showers, counters, concrete, and masonry joints can vary depending on age, materials, and previous repairs.
We look at the actual surface, parts, measurements, and access before recommending the next step. This service is a good fit when the issue needs to be handled before it gets worse, before listing the home, or ahead of another repair or renovation project.
Homes in areas such as Port Credit, Erin Mills, Meadowvale, Clarkson, and City Centre may have different access conditions, finish materials, and joint details, so the work is reviewed on site rather than assumed from photos alone.
Every home is different. Material condition, access, fit, measurements, hardware, and nearby finished surfaces can change how the sealing work should be handled. During the technical visit, our technician checks site conditions, access, materials, measurements, surrounding surfaces, and the scope needed before the quote is finalized.
The visit also helps confirm whether old seal removal, joint preparation, backer rod, drying time, adhesion surfaces, new seal application, edge cleanup, or moisture exposure planning should be part of the work. The next steps are explained in plain language so you know what can be handled and what should happen first.

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.

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.
