Mastic sealing in Charlton-on-Otmoor, done properly
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you have window mastic that has split and shrunk and damaged joints in communal entrances and corridors, we can put it right. Most enquiries from Charlton-on-Otmoor start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Owners and agents with buildings around smaller places such as Charlton-on-Otmoor tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Aftercare for building managers
For the best life from the joints:
- Make mastic part of routine maintenance checks
- Check the asbestos register before any old mastic is disturbed
- Ask residents or tenants to report leaks and draughts early
- Plan resealing building by building rather than complaint by complaint
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Leave it or put it right?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Halls, stores and units around places like Charlton-on-Otmoor may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Mastic sealing around Charlton-on-Otmoor: what changes locally
Charlton-on-Otmoor sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. Charlton-on-Otmoor is about 52 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Buildings close to stations like Islip station (to the west of Charlton-on-Otmoor) are often flats over shops, with frame mastic to keep sound. Older buildings near Charlton-on-Otmoor, from historic houses such as Boarstall Tower, 4 miles east of Charlton-on-Otmoor, to more modest stock, need compatible products when frames are resealed.

Clients typically get in touch after noticing one or more of the following:
- Repeated reactive repairs to the same buildings
- Mastic failing across several blocks on an estate
- Old repairs sealed over failed mastic
- Failed external movement joints
Churches, halls and community buildings such as Church of St Mary the Virgin are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
