Sealant jobs we do in Burnham-on-Crouch
Down on the Quay, wind comes straight off the River Crouch, and buildings along the waterfront feel it in their joints. Mastic around frames, sills and weatherboarding dries out, cracks and lets rain in, often long before anyone notices. Mr Mastic covers Burnham-on-Crouch from our base in Crawley, and we deal with those outside joints as well as the usual bathroom and kitchen work.
Inside the house, we reseal baths, showers, basins and worktops. Outside, we cut out tired mastic around windows and doors and replace it with flexible, weatherproof sealant. In both cases the old material comes out completely first, because new sealant never bonds properly to old. Our window and door mastic page explains the frame types we work on.
Weatherboard, Georgian fronts and newer streets
The historic core has a loose grid plan with a medieval street pattern, a wide market street and many vernacular and Georgian buildings. Materials are an eclectic mix of red brick, mostly white weatherboarding and render, under slate or tile roofs. The conservation area holds 33 listed buildings, among them the Grade II* Royal Corinthian Yacht Club, designed in 1931 by the modernist architect Joseph Emberton, and terraces such as Granville Terrace.
Each material asks something different of a sealant. Weatherboarding expands and shrinks with the weather, so the joint where boards meet a window frame needs a sealant that stays flexible. Render and old brick can be soft, so hardened mastic has to be cut out with care. On a Georgian front, the right product depends on whether the joint will be painted.
Beyond the old centre, housing came in phases through the twentieth century, and the newer areas to the north mix many styles and house types. More is on the way: the town has been allocated 450 new homes across three sites, and 90 homes were approved on land north of Marsh Road. New-build showers and baths often need resealing within a year or two once the house has settled.

Riverside exposure and the estuary weather
The riverside is lined with yacht clubs, jetties and moorings, and the houses nearest the water take the full force of wind-driven rain. South- and west-facing frames also get strong sun, which bakes old mastic until it shrinks back from the brick. We use exterior sealants that cope with movement, set at the right depth with backing rod, and we check sills and the joints below them as well as the frame edges.
Plenty of Burnham’s homes are cottages and terraces with small bathrooms and little ventilation, so condensation sits on the bead. Anti-fungal sanitary silicone and a good clean behind the old bead make a real difference. For upper-floor joints, we’ll talk through safe access before quoting.
Sailing clubs, the marina and holiday lets
Burnham has four sailing clubs, the Royal Corinthian, the Royal Burnham, the Crouch Yacht Club and Burnham Sailing Club, and the yacht harbour marina sits west of the town centre. Clubhouses, changing rooms, showers and bars all have sealant that wears out with heavy use. Holiday lets and guest rooms in town need turning round quickly between visitors.
Springfield Business Park and the premises off Foundry Lane house workshops and offices with staff kitchens and toilets. Our commercial sealant page shows how we plan visits around opening hours.

Burnham-on-Crouch: common questions
Do you cover all of Burnham-on-Crouch?
Yes. We cover the whole town, from the Quay and High Street to the newer northern streets, and nearby Creeksea, Ostend and Southminster.
Why does the mastic round my riverside windows fail so quickly?
Wind, rain and sun all stress external sealant, and old mastic that has hardened can’t move with the frame. A flexible exterior sealant set at the right depth lasts much longer.
Can you seal where weatherboarding meets a window frame?
Yes. We remove the old mastic, check the timber is sound and dry, and use a flexible sealant that copes with the boards moving.
Do you reseal showers in sailing club changing rooms?
Yes. We can work room by room and at quieter times so facilities aren’t out of use for long.
Can you reseal a holiday let between bookings?
Yes. Tell us the changeover dates and we’ll plan around them, leaving time for the sealant to cure.
I’ve bought a new home in Burnham and the bath seal has split. Why?
New houses settle, and builder sealant often can’t cope. We cut it out and reseal with a product that can move.
Is the work guaranteed?
Yes. You get our one-year guarantee on every job.
