Mastic sealing in Preston
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. The enquiries we see most involve estate-wide sealant that is simply worn out and complaints coming in block by block, across balcony and threshold joints, window and door perimeters on blocks and external wall and movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Preston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions near places like Preston often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Aftercare for building managers
A few simple habits keep the new joints working:
- Plan resealing building by building rather than complaint by complaint
- Share the asbestos register when you send details
- Keep bins and bikes away from communal door frames
- Encourage occupiers to report problems at frames
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.

What happens if it’s left?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Older rural buildings around Preston move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Misted or failed double-glazed units
- Water coming in from the roof or rainwater goods
- Masonry that has broken away beside the joint
If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.
Surfaces we seal

Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Frames, entrances and external joints in Preston
Preston is about 59 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first.
Buildings close to stations like Adisham station (to the south of Preston) are often flats over shops, with frame mastic to keep sound. If you are responsible for a building such as Church of St Mildred, frame and door mastic needs the same attention as any other property. With historic buildings such as Goodnestone Park (4 miles south of Preston) in the wider area, owners of older properties around Preston should expect mastic to need a product that suits old masonry.

Common questions from Preston clients
Is Preston off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you quote for a block close to Adisham station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
How long does a job like this take?
It depends on the scope, but the work typically takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you reseal a whole block or estate?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
