Why Toronto Homeowners and Property Managers Choose GPro

We’re not just another caulking company. We’re building envelope specialists who understand how Toronto's climate affects your property.

Building Science Expertise

We understand air barriers, thermal bridging, and moisture control. Our approach applies building-science principles to every project for durable, season-ready protection.

Professional-Grade Materials

We use premium sealants selected for the joint and the materials. Clean tooling, proper cure considerations, and optional color-matching where appropriate.

Trained Technicians

Proper removal, correct surface prep, and consistent application technique. We focus on clean finishes that hold up through movement and weather.

From Homes to High-Rises

Residential, commercial, and larger buildings where access planning and scheduling discipline matter. Scope-defined work with site-respectful execution.

3-Year Warranty

We stand behind our workmanship with a clear warranty policy and straightforward remediation when a warrantable issue is confirmed.

Transparent Pricing

Clear quotes with defined scope. We explain what needs to be done, why, and what it will cost — so you know exactly what you’re getting.

Our Proven 4-Step Process

From initial assessment to final warranty, here’s exactly what to expect when you work with GPro.

  1. Property Assessment

    We inspect your property to identify all areas requiring caulking. We check for visible failures, measure conditions, and identify likely root causes — not just the symptoms.

    • Comprehensive inspection of visible joints and transitions
    • Moisture and air-leakage symptom check (where applicable)
    • Photo documentation of current conditions

  2. Detailed Quote & Plan

    You receive a clear, itemized quote that explains what work is needed, which materials we’ll use, and how scheduling will work. No surprises. No hidden costs.

    • Transparent scope and pricing breakdown
    • Material selection notes (matched to joint/material/movement)
    • Timeline and access planning (including condo rules when needed)

  3. Expert Application

    We properly prepare surfaces, remove failing caulking where required, and apply new sealant with clean tooling for consistent lines and correct joint fill.

    • Removal where the existing sealant is failing or contaminated
    • Surface prep for adhesion (clean, dry, adhesion-ready)
    • Professional application and tooling for a clean finish

  4. Quality Check & Warranty

    Before closeout, we confirm finish consistency and scope completion. If requested, we provide before/after documentation and your 3-year warranty details.

    • Final walkthrough and finish check
    • Care and maintenance recommendations
    • 3-year workmanship warranty (scope-defined)
