Pricing & What Affects the Cost

Small re-caulks are most affordable; costs rise with old bead removal, heavily contaminated joints, high access, or large exterior scopes.

Typical price drivers:

  • Scope & access: Number of openings, ladders/scaffolds, weather windows.

  • Substrate condition: Mold/mildew, failed paint, crumbly mortar, wet joints.

  • Material type: Standard silicone vs. polyurethane/hybrid or specialty fire-rated products.

  • Prep needs: Thorough removal, cleaning, alcohol wipe, primer, backer rod, masking.
    You’ll get a written, line-item estimate so you can choose areas to prioritize now vs. later.

Materials & Where They Work Best

  • 100% Silicone (kitchen/bath): High moisture resistance; great for tubs, showers, sinks, stone/tile.

  • Paintable Acrylic/Latex (interior trim): Smooth, low odor; paint within hours for crisp lines.

  • Polyurethane/Hybrid (exterior): Flexible, durable, excellent adhesion to masonry/siding.

  • Butyl/Flashing Sealants (roof/chimney): Stays flexible in temperature swings.

  • Fire-Rated / Intumescent (commercial): Penetrations and assemblies per code.
    We select products for movement, UV, temperature, and paintability—and we always use backer rod where joint depth/width demands it.

Our Process

Step 1 – Inspect & Quote:

Identify failed joints and moisture paths; provide a clear estimate and product plan.

Step 2 – Prep:

Remove old caulk, clean/dry surfaces, set backer rod where required, and mask edges.

Step 3 – Apply & Tool:

Install the correct sealant, tool for adhesion and smooth finish, then clean edges.

Step 4 – Final Check:

Cure times, paint instructions (if applicable), and care tips.

Mini Case Study

A Pickering home had mildewed shower seams and drafty windows. We stripped contaminated beads, disinfected and dried the joints, installed a backer rod, and applied mildew-resistant silicone in the bath. Outside, we removed brittle perimeter caulk and used a hybrid exterior sealant around windows and doors. Result: tighter envelope, lower drafts, and a fresh, clean look.

Benefits

  • Prevents water damage and mold

  • Cuts drafts for better energy efficiency

  • Extends life of finishes, tile, and frames

  • Clean, professional appearance

Frequently Asked Questions

How often should I re-caulk?

Baths: typically 3–5 years. Windows/doors: 5–10 years, sooner with heavy sun/water exposure.

How long before I can shower/paint?

Most silicones need 24 hours before heavy water. Paintable interior caulks can be painted once skinned/cured per label.

Do you handle small jobs?

Yes—single tub, a few windows, or touch-ups are common service calls.

What if there’s hidden moisture or rot?

We’ll pause, show findings, and quote any substrate repair before re-sealing so it lasts.

Do you offer exterior whole-home sealing?

Yes—seasonal packages to refresh siding joints, penetrations, and window/door perimeters.
