Common Sealant Problems We Fix
Over time, sealant can dry out, crack or split due to movement and temperature changes. This leaves gaps that allow water, cold air and moisture to enter the property.
Failed or poorly applied sealant around windows and doors can cause noticeable draughts and heat loss. Fresh sealant restores airtightness and helps improve energy efficiency.
Bathrooms and kitchens are especially prone to mould growth when sealant breaks down. Replacing old silicone improves hygiene, appearance and prevents moisture damage.
Damaged or missing sealant can allow water to penetrate walls, frames and joints, leading to staining or internal damage. Proper sealant installation helps protect the structure of your home.
