Resealing and mastic work across Braintree
If you’re looking for a mastic man in Braintree, Mr Mastic covers the town, Bocking and the villages around them from our base in Crawley. We reseal baths, showers, basins and kitchen worktops, replace tired mastic around windows and doors, and look after businesses and rented homes across the district.
Most sealant problems we see have one of three causes: the old bead has simply reached the end of its life, it was laid over older sealant, or the joint was never cleaned properly before sealing. Black spots that keep coming back are usually mould growing behind or under the bead, and wiping it only helps for a while. Our anti-mould resealing service removes the lot and replaces it with an anti-fungal silicone that is much better at resisting it.
From Bradford Street to Great Notley
Braintree is an old market and textile town. The Braintree Town Centre and Bradford Street conservation area holds more than 130 listed buildings, from timber and plastered town houses to Bradford Mill, and Bocking Church Street has its own conservation area. Older homes here often have uneven walls and floors, so the gap between a bath and the tiles is rarely the same width along its length. We fill deep gaps properly rather than bridging them with a thin bead that will split in weeks.
Through the 20th century the town spread out into estates on both sides of the old centre, and from the 1990s Great Notley Garden Village was built to the south west, mostly by Countryside Properties. Homes from that period are now 25 to 30 years old, and many still have their first bathroom and kitchen sealant, which by now has usually shrunk, yellowed or come away at the corners.
Braintree is also where the Crittall window business began in 1849. A few miles away, the company built Silver End as a model village from 1926, with white, flat-roofed modernist houses. Steel window frames expand and contract more than timber, so they need a flexible, well-bonded sealant at the joints. Rigid fillers and cheap caulk crack away from steel within a season or two, so we never use them there.

Steel frames, Article 4 rules and older flats
In the Silver End conservation area, an Article 4 Direction removes permitted development rights for changes such as replacement windows and doors. That makes careful repair of existing frames more important, and sealing around metal windows is a job where the right product and a clean, primed joint make the difference. Our glazing sealant page covers the work in more detail.
In the town itself, flats above shops on the High Street and Bank Street, and converted older buildings, bring their own access questions. We plan parking and carrying equipment up narrow stairs before the day, and we take extra care with shower seals where a leak would reach a shop or flat below.
Braintree Village, business parks and industrial estates
Braintree Village, the designer outlet on the edge of town, sits alongside retail parks, cafés and restaurants that all need clean, intact sealant in customer toilets and kitchens. Industrial areas such as Springwood, Broomhills and Park Drive, and the Skyline120 business park at Great Notley, have offices, welfare blocks and staff showers that wear out sealant quickly.
We take on commercial sealant work at times that suit the business, and we also work for landlords and letting agents who need a property resealed before a new tenancy starts. Tell us how many bathrooms and kitchens are involved and we can plan the visit so everything is done in one go.

Braintree: common questions
Do you cover all of Braintree?
Yes. We cover Braintree town, Bocking and Great Notley, and villages such as Rayne, Black Notley, White Notley, Cressing, Stisted, Panfield and Silver End.
My Great Notley house still has its original bathroom sealant. Should it be replaced?
After 25 years or so most sealant has hardened or shrunk. We cut it all out and reseal with anti-fungal silicone.
Can you seal around steel windows like those at Silver End?
Yes. We clean and prime the metal and use a flexible sealant suited to steel frames, finished neatly to suit the house.
Do I need permission to reseal windows in a conservation area?
Resealing an existing frame is a repair, not a replacement. If you’re planning bigger changes, check with Braintree District Council first.
Can you work at a shop or restaurant out of hours?
Yes, out-of-hours working can be arranged so customer areas are ready when you open.
Why does mould keep coming back on my shower seal?
Usually it is growing behind or under the bead. Cleaning the surface doesn’t reach it, so the sealant has to come out and be replaced.
Will I get a fixed price?
You’ll get a clear quote before we start, so you know exactly what the job involves.
