Common questions about sealant work
Real answers from our Dorking experience with water damage, listed buildings, and mould issues
Can you fix mould growing behind old sealant in Dorking bathrooms?
Yes — mould growth behind failed sealant is one of the most common bathroom problems we solve in Dorking. Old sealant (usually cheap acrylic or expired silicone) breaks down, water gets behind it, and mould thrives in the damp space.
How it happens: Acrylic sealant is not fungal-resistant. Water penetrates behind it. Mould grows on the substrate. Cleaning with bleach doesn't work — it returns within weeks because the underlying sealant is still wrong.
Our solution: Complete removal of old sealant. Cleaning and drying. Application of professional anti-fungal silicone designed to prevent mould growth. Proper ventilation advice.
Case study: High Street Victorian property — customer had been fighting mould for 5 years. We sealed it properly, mould stayed gone.
Do you seal Victorian listed properties in Dorking's conservation area?
Yes — Dorking has 250+ listed buildings and a large conservation area since 1974. We specialise in heritage property sealant work and understand period building requirements.
We understand: Period-appropriate finishes. Conservation area standards. Grade II listed property requirements. Heritage colour matching. Respect for historic character. West Street's 16th century buildings. Victorian/Edwardian architectural integrity.
Case study: Grade II listed West Street property had water damage from failed shower. We sealed it with heritage-appropriate approach. Listed building preserved, customer relieved.
Can you fix water ingress into walls from failed shower sealant?
Yes — water damage from failed shower sealing is serious and threatens structural integrity. This is a genuine emergency requiring professional assessment and repair.
Warning signs: Water staining on external wall. Dampness visible. Plaster damage. Structural concerns. Windows/doors showing water marks.
Our approach: Full cavity inspection. Assess damage extent. Dry affected areas. Remove old failed sealant completely. Apply professional waterproof silicone. Monitor for further issues.
Case study: West Street listed property — water seeping into wall cavity from 5-year-old failed shower. We assessed, repaired, prevented further structural damage.
How quickly can you respond to Dorking water damage emergencies?
Very quickly — for water damage or bathroom emergencies, we aim for same-day survey or next-morning visit from our Dorking base. Structural damage worsens with time, so speed matters.
Emergency example: Customer called Monday afternoon about water coming through wall from failed shower. We surveyed Tuesday morning. Started repair work Wednesday.

Do you seal West Street antique/listed properties?
Yes — West Street is Dorking's Antique Row with many 16th century Grade II listed properties. We have specialist experience with period buildings and heritage standards.
Challenges we understand: Grade II listing requirements. Historic material compatibility. Period window frames. Original plasterwork. Conservation area sensitivity. Architectural character preservation.
Case study: Grade II listed West Street property — water damage threatening listed structure. We assessed and repaired with heritage-sensitive approach.
What warranty covers sealant failure?
