The Trade Standard

Why 9 Out of 10 Sealant Jobs Fail (And What We Do Differently)

Most homeowners call us after another tradesperson has already attempted their silicone—only for it to turn black with mould or peel away in 6 months. Here is why the industry has a quality problem, and how our family team guarantees permanent results.

The Cowboy Shortcut

Capping Over Damp Mould

Unqualified handymen often smear fresh silicone directly over dirty old beads in 15 minutes. The trapped moisture and mould bacteria rot the new bead from the inside out, causing it to peel like wet tape and leak water into ceiling plasterboard below.

Result: £1,500+ in rotted timber joists and ceiling damage.

The Specialist Standard

100% Surgical Excision

We spend 70% of our time on preparation: slicing away 100% of old rubber down to bare tile glaze, treating joints with hospital-grade biocides, degreasing with fast-flashing solvents, and tooling commercial anti-fungal silicones with specialist profiling blocks.

Result: Pristine, watertight lines that stay bonded for years.

Our Written Promise

5-Year Free Return Guarantee

Because we take no shortcuts, we back all domestic silicone reseals with our written 5-Year Domestic Guarantee. If any joint peels, lifts, or leaks under normal use, send us a photo on WhatsApp. Liam arranges a priority return visit to reseal it 100% free of charge.

Result: Total peace of mind with zero risk.
