A small window or door exterior caulking and sealing issue can become a bigger headache when sticking, rubbing, loose hinges, damaged frames, latch issues, worn seals, or tired hardware are ignored. CNG Contracting reviews the actual surface, parts, measurements, and access so the right next step is clear.
This service is a good fit for Mississauga homeowners in detached homes, executive townhouses, condos, and waterfront properties who need help when a door no longer closes properly, gaps are visible, drafts are noticeable, or exterior caulk and seals are starting to fail. We keep the work practical and focused on what can be confirmed on site.
Homes in areas such as Port Credit, Erin Mills, Meadowvale, Clarkson, and City Centre can have different access, age, and exterior finish conditions, so the details are checked at the property rather than assumed.
Every home is different. Frame alignment, hinge wear, slab condition, floor clearance, storm door operation, and hardware fit can all change how the work should be handled. During the technical visit, the technician reviews site conditions, access, materials, measurements, and the expected scope before the quote is finalized.
The visit may include checking hinges, frame, jamb, latch, strike plate, swing clearance, weatherstripping, threshold contact, screw points, nearby finishes, and exterior caulk condition. The goal is to explain what is possible, what should happen first, and what materials or adjustments may be needed in plain language before any work is approved.

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.
