Banbury: old stone, new homes and logistics
Banbury has grown quickly, and its buildings show it.
The older streets around the Market Place, Calthorpe and Easington have ironstone and brick houses with timber windows, where mastic needs to be soft enough for the stone and neat enough not to spoil it. Bretch Hill, Hardwick and Grimsbury have post-war homes, while Banbury Rise and the newer estates towards Bodicote have thousands of uPVC windows whose builder's mastic is starting to crack.
Next to junction 11, warehouses and factories carry long runs of cladding and concrete joints. As a sealant contractor that works for main contractors as well as homeowners, we can quote for a single bathroom reseal or a full warehouse joint schedule in Banbury.
Banbury Cross, Spiceball and Castle Quay show how much the centre has changed, and the canal-side apartments near Tramway bring balconies and curtain walling that need periodic inspection and resealing.

Concrete and movement joint sealing near the M40
Distribution centres and factories around Banbury take heavy traffic from forklifts and lorries. Floor joints that have lost their sealant break up at the edges, and wall movement joints let in water and dust.
We clean out failed joints, fit backer rod and reseal with polyurethane or, where fuels and chemicals are present, polysulphide sealant. Work can be phased around your operations, including out of hours.
- Polyurethane and polysulphide sealants
- Joint schedules priced from drawings
- RAMS supplied before we start
- Work phased around operations

Domestic silicone sealant done properly
In Banbury homes we reseal baths, showers, basins and kitchen worktops, and renew the external mastic around windows and doors. Each job starts with removing all the old sealant, because new silicone over old never lasts.
Landlords and letting agents use us between tenancies, and builders bring us in to finish extensions and refurbishments with a clean, professional sealant line.
We also re-mastic uPVC windows to stop draughts, seal expansion joints, reseal en-suites and wet rooms with sanitary silicone, handle new-build snagging, and work as a façade and curtain wall sealant applicator on commercial buildings. Shower resealing and bathroom resealing in Banbury are priced up front, so you know the cost before we start.

Banbury mastic and sealant FAQs
How much do you charge for mastic work in Banbury?
Prices depend on the length of joint, access and sealant type. Most domestic jobs are priced from photos, and we confirm a fixed price before we start. For commercial work we price from drawings or a joint schedule.
Do you seal ironstone and older properties?
Yes. On Hornton ironstone and soft brick we use non-staining, low-modulus sealants and cut out failed material first so the joint can move without damaging the stone.
Can you seal warehouse floor joints in Banbury?
Yes. We seal concrete floor joints and wall movement joints with polyurethane or polysulphide sealant and can work out of hours to keep your site running.
Is there a mastic man near me in the Banbury villages?
Yes. We cover Bodicote, Adderbury, Bloxham, Cropredy, Middleton Cheney and the other villages listed on this page.
