Your local mastic man for Witham
Witham grew up in two places. The Saxon settlement centred on Chipping Hill, about half a mile north of the Roman road, and Newland Street is now the main street of the town centre. Since the late 1960s, large estates have been added on three sides, and the town is still growing. Mr Mastic covers all of it from our base in Crawley.
Kitchens are a big part of our work in a town of family homes. Worktop and sink joints take daily splashing and wiping, and once the sealant lifts, water gets into the chipboard below and the worktop swells. We cut out the old bead, clean and dry the joint and reseal, with a food-safe product near the sink. Our kitchen resealing page has the details.
Georgian fronts, overspill estates and Maltings Lane
Newland Street looks Georgian, but many of its buildings are older timber-framed houses refaced in brick. Highway Cottage, number 118, is a late 14th-century hall house. Warm red brick and gault brick fronts sit alongside timber frames finished in pale render, and painted timber sliding sashes are the usual window. The council’s appraisal for the conservation area prefers lime render to hard cement render.
That has a direct effect on sealant. Lime render and old brick are soft and breathe, so the joint around a sash should use a product that suits them, and hardened mastic needs careful removal. Many of these frames will be painted, so a paintable sealant is often the right choice rather than silicone.
In the late 1960s and 1970s the Greater London Council built three large council estates on the west and north sides of Witham and a smaller one to the south, to house families moving out of London. The Forest Road estate, home to the Rickstones neighbourhood centre, dates from the 1970s. To the south, the Maltings Lane estate was started in 2002 and 2003, and Witham has kept growing since. Bathrooms in the older estates have often been refitted more than once; in the newer homes, builder sealant often needs replacing early.

Flats over shops and estate maisonettes
Along Newland Street, many period buildings have shops on the ground floor and flats above. A failed bath or shower seal upstairs can quickly show as a stain in the shop below, so we look closely at the corners and screen edges where leaks usually start. In the 1970s estates, blocks of flats with shops beneath and stacked maisonettes bring the same risk.
On the estates, it is common to find replacement uPVC windows whose mastic has aged, hardened and pulled away from the brick. We cut it out and replace it with a flexible exterior sealant. If you are wondering whether your sealant is due for renewal, our guide to how long silicone sealant lasts will help.
Industrial estates by the A12 and commuter homes
Witham’s industry is concentrated on three industrial estates on the eastern side of the town near the A12. Factories, offices and warehouses there have staff kitchens, toilets and showers, and we can work early or after hours so they stay in use. The leisure centre on Spinks Lane, opened in 2014, is the kind of busy site where changing-room sealant wears fast.
Witham station is on the Great Eastern Main Line, about 40 to 45 minutes from Liverpool Street, which keeps demand for rented homes strong. We reseal between tenancies for landlords and letting agents.

Jobs we take on in Witham
- Bathroom & kitchen resealing: Baths, showers, basins, wet rooms, worktops and sinks: old sealant cut out, mould treated and a new bead of anti-fungal silicone laid.
- Window & door mastic: Hardened, gappy mastic around frames, sills and French or patio doors cut out and renewed to keep draughts and rain out.
- Commercial & hotel sealant: Commercial washrooms, kitchens and wet areas resealed floor by floor, so only a few rooms are out of use at once.
- Remedial sealant & repairs: Second opinions on sealant that keeps failing: we strip it out, check for movement or leaks and reseal it properly.
- Fire-rated sealant: Intumescent and fire-rated joints around pipes, cables and frames, installed to the manufacturer’s tested specification.
- External & façade joints: Brickwork movement joints, render and cladding joints resealed with backing rod and flexible exterior sealant.
- New-build mastic & snagging: Failed builder sealant in new homes put right, and plot mastic for developers.
- Floor & skirting joints: Movement joints in tiled and concrete floors, and skirting gaps, sealed so they stay tidy and keep dirt out.
- Regrouting: Crumbling grout in showers and wet areas raked out and refilled, so water stays out of the wall behind.

- Gutter, fascia & soffit sealing: Gutter unions, outlets and fascia joints that leak in heavy rain cleaned and resealed.

Questions we’re asked in Witham
Do you cover all of Witham?
Yes. We cover the whole town, including Chipping Hill, Newland Street, the Forest Road and Rickstones area and Maltings Lane, plus nearby Rivenhall, Silver End and Faulkbourne.
My kitchen worktop is swelling by the sink. Is that the sealant?
Very often. Once the bead lifts, water gets into the board beneath. We reseal with a food-safe product, but a badly swollen worktop may need replacing first.
Can you seal round sash windows on Newland Street?
Yes. We choose a sealant that suits the timber and the brick or render, and use a paintable product where the joint will be painted.
Do you reseal around uPVC windows on the estates?
Yes. We cut out the old, hardened mastic and replace it with a flexible exterior sealant in a matching colour.
Can you work on the industrial estates out of hours?
Yes. Out-of-hours visits can be arranged so staff facilities aren’t out of action during the day.
I live in a flat above a shop. Can you help?
Yes. We pay extra attention to the bath and shower joints, because a leak there can reach the shop below.
Is the work guaranteed?
Yes. Every job carries our one-year guarantee.
