Folkestone, Kent

Mastic Sealant Specialist in Folkestone

Sharp lines, mould-resistant silicone and a finish that lasts. The Mastic King covers all of Folkestone and the surrounding CT18–CT20 postcodes — same-day visits available.

Folkestone is a coastal town with a wide variety of housing stock — from Victorian terraces in the town centre and Sandgate Road to modern apartments along the seafront and the regenerated Creative Quarter. We cover the full CT18–CT20 postcode range and are in the area regularly. Coastal properties face particular challenges with sealant. The combination of salt air, high humidity and temperature fluctuations accelerates silicone degradation faster than inland properties. We see a lot of Folkestone bathrooms where the sealant has failed within two or three years of the last reseal — often because the wrong product was used or it was applied over old sealant. We use premium marine-grade silicone where appropriate and always start from bare surface. Folkestone's older housing stock — particularly the large Victorian and Edwardian properties on the Leas and in Sandgate — often has original bathroom fittings or period-style suites that need careful handling. We're experienced with older sanitaryware and take care to match sealant colour to the existing grout and fittings. We also carry out commercial work in Folkestone, including hotels, guest houses and the town's growing hospitality sector.

Frequently asked questions — Folkestone

How quickly can you get to Folkestone?

We cover Folkestone regularly and can usually offer a same-day or next-day visit. Call or WhatsApp us and we'll confirm a time that suits you.

Do you remove the old silicone before applying new sealant?

Always. We fully strip the old silicone, clean and dry the surfaces, then apply fresh mould-resistant sealant. Applying new silicone over old is a shortcut we never take.

Does coastal air affect sealant more quickly?

Yes — salt air and high humidity accelerate silicone degradation. We use premium products suited to coastal environments and recommend checking sealant condition every two to three years in Folkestone properties.

Are you insured?

Yes — fully insured for public liability. You're in safe hands.

Do you cover Hythe and Sandgate?

Yes — we cover Hythe, Sandgate, Hawkinge, Cheriton and all surrounding CT postcodes.
