A small air drafts sealing job can become a bigger repair when loose parts, damaged surfaces, worn hardware, awkward access, or unfinished repair work are ignored. CNG Contracting checks the actual surface, parts, measurements, and access before recommending the next step for your Guelph home.
This service is a good fit for homeowners who need gaps, failed caulk, worn silicone, or exposed joints handled before the issue gets worse, prior to listing the home, or ahead of another repair or renovation. In Guelph, this can apply to heritage limestone homes, post-war detached houses, and newer suburban properties where materials and access can vary from room to room.
Our air drafts sealing service focuses on checking and sealing common gaps and joints where condition, fit, moisture, or movement can affect the repair.
Homes in areas such as Downtown Guelph, Exhibition Park, Kortright Hills, and the East End may have different surface conditions, ages, and access challenges, 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 air drafts sealing should be handled. During the technical visit, our technician reviews the work area, surrounding surfaces, joint size, old sealant condition, clearance, and any moisture or adhesion concerns.
The visit also helps confirm whether old seal removal, joint preparation, backer rod, drying time, edge cleanup, or curing time needs to be planned into the scope. Once the site conditions, materials, measurements, access, and scope are checked, the work needed is explained in plain language and the quote is finalized for approval.

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.

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.

Yes. We can review drafty window gaps, door gaps, old caulk, silicone seams, and joint areas in Guelph homes, then identify what can be sealed and whether damaged surfaces, worn hardware, or access issues need approval first.
It can. Heritage limestone, post-war detached homes, and newer suburban houses can have different wall surfaces, trim conditions, window fits, door clearances, and previous caulking. Those details affect preparation, material choice, and the sealing approach.
During the technical visit, we check the draft locations, materials, hardware, access, measurements, and nearby finished surfaces. We then explain the recommended scope and quote so the work is clear before you approve sealing.
Book before painting, flooring, staging a Guelph home for sale, or starting nearby renovation work. Move furniture or storage away where possible and note the main draft areas so access and measurements are easier during the visit.
