Mastic and sealant work in Farnborough
Farnborough grew from a village of a few hundred people in the early 1800s into a town of more than 57,000 by 2011, and most of that growth came after the Second World War, when new residential areas, business parks and light industrial estates were laid out around the old centre. That gives the town a wide spread of house ages, and a wide spread of tired sealant. Mr Mastic covers Farnborough from our base in Crawley, resealing baths, showers, basins and worktops and renewing mastic around windows and doors.
Every job starts the same way. The old bead is cut out in full, mould spores are cleaned off, the joint is dried, and only then does new sealant go on, picked for the surface and the movement it has to cope with. If a bathroom joint keeps turning black a few months after you last cleaned it, our page on anti-mould resealing explains what we do differently.
Old villages, post-war estates and a town centre being rebuilt
Farnborough is really several places joined together. Cove, on the western side, is an old village that appears in the Domesday Book and has long since become a suburb of the town, sitting next to Southwood and Hawley. North Camp, on the Aldershot side, takes its name from the northern half of the army camp that arrived on the heath in 1854. Between and around them are the post-war streets that housed the town’s growing population, with semis, terraces and blocks of flats from several decades.
Homes of that age have usually had their bathrooms and kitchens replaced at least once, and sometimes the new suite was simply sealed over the old joint. Acrylic baths that flex under the weight of a full tub, shower trays laid on timber floors, and worktops butted against uneven tiling all crack a stiff or poorly bonded bead. Outside, replacement uPVC windows from the 1990s and 2000s often have mastic that has hardened, shrunk back from the brick and gone grey and gritty.
The town centre is changing too. Rushmoor Borough Council has a regeneration plan worth more than £100 million that brings a cinema, restaurants and new homes into the centre over the coming decade. New flats bring new-build sealant, and that first bead often splits as a building dries out and settles. Our guide to new build sealant snagging lists what to look for in your first year.

Flats, shared houses and garrison-edge streets
A lot of Farnborough’s sealant work is in flats, and that changes the job. A shower tray that leaks along one edge in a first-floor flat usually shows itself on the ceiling below before anyone upstairs notices. We look at the tray, the screen and the wall corners together, and we can talk to a managing agent about access, parking and keys before we arrive. Parking near North Camp and the town centre can be tight, so it helps to tell us what is available when you book.
On the houses, the main outside jobs are window and door frames, sills and the joints where newer extensions meet older brickwork. Those joints move a little with the seasons, so we use a flexible weatherproof sealant and backing rod where a gap is too deep to fill in one go.
Aviation offices, colleges and letting agents
Farnborough Airport is a business aviation hub, and the Air Accidents Investigation Branch is based there, so the town has a large number of offices, hangars and staff facilities. Education is also big here: the Sixth Form College has around 4,000 enrolments a year, and Farnborough College of Technology works from a 100-acre campus alongside University Centre Farnborough. Washrooms, staff showers and kitchens in buildings like these get heavy use, and we can work out of hours so they are not closed during the day.
Landlords and letting agents are a regular part of our work across Rushmoor. We reseal between tenancies and after tenants report mould, and can quote for several properties at once.

Questions from Farnborough
Do you cover all of Farnborough?
Yes. We cover the whole town, including Cove, Southwood, North Camp and the town centre, and neighbouring Hawley, Aldershot and Frimley.
I’ve bought a flat in one of the new town-centre schemes and the shower seal has split. Can you help?
Yes. Early splitting is common as new buildings settle. We cut the original bead out, prime if needed and reseal with a flexible sanitary silicone.
Can you reseal staff washrooms at an office near the airport before the working day?
Yes. Out-of-hours working can be arranged for commercial jobs so staff facilities stay open during the day.
My 1960s semi has had three bathrooms over the years. Will there be layers of old sealant?
Quite possibly. We remove every layer back to a clean surface, because new silicone will not bond properly to old silicone.
Do you work for Farnborough letting agents?
Yes. We reseal between tenancies and can quote for a batch of properties together.
How long should I leave the bath before using it?
Usually around 24 hours. We will tell you the cure time for the product we used before we leave.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
