Resealing and mastic work across Wivenhoe
Wivenhoe’s old streets run down to the tidal River Colne, where the town once built ships and yachts. Above them, newer housing has spread up the hill and absorbed the old hamlet of Wivenhoe Cross, and the University of Essex sits in Wivenhoe Park just beyond. Mr Mastic covers Wivenhoe from our base in Crawley, resealing baths, showers, basins and kitchens, and replacing mastic around windows, doors and glazing.
The river matters to sealant. Damp air off the estuary and wind across open water work on outside joints, and older cottages with small bathrooms hold condensation. We remove old sealant fully, treat and dry the joint, and choose a product for where it is going. After a reseal, our guide on looking after new sealant explains how to keep it clean.
Conservation streets, shipyard housing and the hill
Much of lower Wivenhoe is a conservation area. Colchester’s heritage records describe two parts: an older core of vernacular buildings and irregular streets around the Quay and the former market place, and more formal nineteenth-century streets laid out in straight lines. High Street, West Street, Alma Street, Anchor Hill and The Quay hold many of the town’s listed buildings. In houses like these, walls and frames are rarely square, and a sealant needs to be flexible and neatly tooled to look right.
The shipbuilding sites have become housing. The Wivenhoe Shipyard, the last to work in the town, closed around 1961 and was later sold for nearly 300 homes. Cooks Shipyard became 98 houses and flats with offices and live/work units fronting the river. Waterside buildings like these have large windows and metal roofs, and their glazing and external joints face the weather head on.
Further up the hill, twentieth-century houses and estates fill the ground between the old town and Wivenhoe Cross. Bathrooms there are typically on their second or third refit, and replacement windows are at the age where the mastic has gone hard.

Riverside flats, cottages and student houses
In the converted shipyard blocks, a failed shower or bath seal can soak into the flat below, and the managing agent will often want the work booked through them. We are used to that, and to working with residents’ parking and narrow riverside access. On balconies and large window walls, our glazing sealant work replaces perished joints between glass, frame and wall.
In the conservation area cottages, small bathrooms tucked under the eaves or at the back of the house are common. The joints there are short but awkward, and getting a clean, even bead in a tight corner takes patience rather than speed. We also check the basin and the edge of the bath panel while we are there, since those joints are often missed on a quick refit; our basin and sink resealing covers them.
Student lets, pubs by the water and small businesses
With the University of Essex next door, a lot of Wivenhoe houses are let to students and staff. Shared bathrooms in those houses get heavy use, and sealant often needs renewing each summer before a new group moves in. Our landlord sealant service is built around those changeovers.
Pubs along the waterfront, and the shops on the High Street, have kitchens and customer toilets that need attention from time to time. We can work outside opening hours. Around kitchen sinks and bar basins, we use food-safe and anti-bacterial products.

Your questions about mastic work in Wivenhoe
Do you cover all of Wivenhoe?
Yes. We cover the old town by the Quay, the former shipyard developments, the streets up to Wivenhoe Cross, and nearby Rowhedge and Fingringhoe.
I let a house to students. When is the best time to reseal?
Early summer, between tenancies. Shared bathrooms wear sealant quickly, and a fresh seal before new tenants arrive helps prevent mould and leaks.
My riverside flat has a leaking balcony door. Can you help?
Yes. We cut out perished sealant around the frame and threshold and replace it with a flexible, weatherproof product.
My cottage bathroom is tiny and nothing is square. Is that a problem?
Not at all. Old, uneven joints are common in Wivenhoe’s older houses; we pack deep gaps and tool the bead to suit.
Can you work with our block’s managing agent?
Yes. We can arrange access and timings through the agent and send photos once the work is done.
Can you reseal a pub kitchen?
Yes. We work before or after opening and use food-safe sealant around preparation areas and sinks.
How long does a reseal take?
Most baths and showers take two to three hours. The sealant then needs about 24 hours before the bathroom is used, and we will confirm the exact time for the product.
