A small air drafts sealing job can become a bigger repair when loose parts, damaged surfaces, worn hardware, awkward access, or unfinished seal work are ignored. CNG Contracting helps Hamilton homeowners deal with draft-prone gaps, failed caulk, silicone seams, and open joints by checking 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 renovation or repair project. In Hamilton properties, from older Victorian homes to executive detached houses and newer builds, material condition and access can vary a lot, so the technical visit is used to confirm what is possible and what should happen first.
Our air drafts sealing work focuses on practical sealing and joint repair areas where gaps, failed sealant, or worn edges can affect comfort, moisture protection, or finished surfaces.
We also review curing time, moisture exposure, nearby finishes, and whether loose or damaged surrounding material should be addressed as part of the scope.
Every home is different. A sealing job in Dundas, Ancaster, Waterdown, Stoney Creek, Binbrook, Westdale, or Kirkendall may involve different surfaces, trim details, masonry conditions, or access limits. That is why the work is not treated as a one-size-fits-all repair.
During the technical visit, the technician checks site conditions, access, materials, measurements, hardware, surrounding surfaces, and the likely scope of work. These details help determine whether old sealant should be removed, whether the joint needs preparation, and what type of new seal application is suitable.
After the review, the recommended next steps are explained in plain language. The quote is finalized only after the relevant site conditions, access, materials, measurements, and scope have been checked.

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. Material condition, painted or masonry surfaces, worn hardware, uneven gaps, previous caulking, and nearby finished trim can change the sealing method. Older Hamilton homes may need extra care around original surfaces before new sealant is applied.
During the technical visit, we check materials, hardware, access, measurements, surrounding surfaces, and where air is entering. The technician explains the recommended scope and quote in plain language, so you can approve the next step before work begins.
Book before painting, flooring, listing the home, or starting another project that may block access. Before the visit, try to clear window sills, door areas, tubs, counters, or joints so measurements and surface checks are easier.
