Your local mastic man for Deal
Deal is a town of narrow old streets, tall seafront houses and long rows of Victorian terraces, and almost every one of those homes has a bath, shower, worktop or window frame that relies on a good line of sealant. Mr Mastic travels to Deal from our base in Crawley to reseal bathrooms and kitchens, cut out and renew window and door mastic, and seal the external joints that let the weather in on this exposed stretch of the Kent coast.
Our method does not change from house to house. The old bead is removed completely, the joint is cleaned back to a sound surface and dried, and then a sealant suited to the job goes in: anti-fungal silicone in a shower, a flexible weatherproof product round a frame, a paintable option where an older timber window needs it. If your sealant is going black within months of being done, our guide to why sealant goes mouldy explains the usual causes.
Three conservation areas and a lot of replacement windows
Deal’s Middle Street area was designated in 1968, the first conservation area in Kent, and its closely packed old houses run parallel to the seafront. Inland, Upper Deal has its own conservation area around St Leonard’s Church, designated in 1970, with around 100 homes spanning more than three centuries in brick and timber under Kent peg tile or slate roofs. Between the High Street and Deal Castle, the Victoria Road and Wellington Road conservation area mixes Georgian and Regency houses, Victorian villas and late 19th-century terraces, with tall double-height bays on Blenheim Road and Gilford Road.
The council’s own appraisal notes that many houses in that area now have uPVC replacement windows and doors. That matters for sealant. Where a plastic frame sits in an opening built for a timber sash, the gap round the edge is often uneven and has been filled with a single thick bead that has since hardened and split. We cut it out, use backing rod where the gap is deep, and finish with a flexible sealant that can move with the brickwork.
Inside, older houses tend to have bathrooms added into back additions or former bedrooms, often on timber floors that flex. A rigid or over-thin bead tears along the back of the bath, and the first sign is usually a stain on the ceiling below.
Shingle beach, sea air and tight streets
Houses along the front face straight out over the shingle beach towards the Channel, and frames on the seaward side take sun, wind and salt spray all year. External mastic there dries out and loses its grip sooner than it would a few streets back, so we check sills and the joints under them as well as the frame edges. Where a window or door can only be reached from a balcony or with tall ladders, we talk through safe access before we quote.
Parking can be the hardest part of a job in the older streets. In Middle Street and the lanes around it, and around the busy junctions in Upper Deal, it helps if you can tell us where we can stop to unload. For flats in converted houses, we are happy to agree access with the building owner or managing agent first.
Holiday lets, guest houses and the High Street
Deal draws plenty of visitors, and holiday lets and guest houses are part of the town. A bathroom used by a new set of guests every few days needs its sealant kept clean and sound, and changeover days are a good time for us to reseal so it can cure before the next arrival. Our page on sealant for landlords covers rented and let property.
The High Street, with its independent shops at the North End, has cafés, restaurants and shops with staff kitchens and washrooms. Out-of-hours working can be arranged so a commercial reseal does not get in the way of trading.

Nearby towns we cover
Deal: common questions
Do you cover all of Deal?
Yes. We cover the whole town, including the Middle Street area, Upper Deal, the streets around Victoria Road, and neighbouring Walmer.
My house is in a conservation area. Does that affect resealing?
Resealing a bath or shower is not affected. For external work around windows on conservation-area houses, we can match the sealant colour to the frame so the joint stays discreet.
The mastic round my uPVC windows has split. Can you replace it?
Yes. We cut out the old bead completely, clean the frame and brickwork, and apply a new flexible weatherproof sealant, with backing rod where the gap is deep.
Can you reseal my holiday let between guests?
Yes. A changeover day works well, as the sealant can cure before the next guests arrive. Tell us the dates and we will plan around them.
Why does the sealant on my seafront house fail sooner than inland?
Salt air, wind and strong sun dry out external mastic and stress the joint. A flexible sealant set at the right depth lasts much longer than a thin surface bead.
Can you seal around an old timber sash?
Yes. Where the joint needs painting afterwards, we use a paintable sealant rather than silicone and explain the difference before we start.
How long will the shower be out of use?
Usually around 24 hours after we finish. We will tell you the cure time for the product used before we leave.
