About our mastic sealing in Crowhurst
Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on communal entrances and stairwells, external wall and movement joints and balcony and threshold joints, and the usual reasons a site gets in touch are failed external movement joints and damp patches beside frames. One point of contact handles commercial sealant work in Crowhurst from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like Crowhurst, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.
Planned maintenance
Resealing can be scheduled alongside other planned works on a timetable you set.
Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Crowhurst need work, visits can be combined. You’ll have a fixed quote before work starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Move anything stored against the joints
- Tell us which areas need to stay in use
- Confirm the product named in the specification

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. Converted and older buildings near places like Crowhurst tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Questions we’re asked in Crowhurst
Is Crowhurst off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work at a site such as Bexhill Enterprise Park, by Crowhurst?
Yes. We cover Crowhurst and the area around it, including industrial estates, business parks and retail parks such as Bexhill Enterprise Park. A few photographs and the unit address let us price the work.
Can you seal joints high up on a block?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Looking after the joints
Regular inspection catches problems early. Specifically:
- Make mastic part of routine maintenance checks
- Share your contractor requirements early
- Encourage occupiers to report problems at frames
- Start inspections with the most exposed faces
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Mastic sealing in Crowhurst: the local picture
Rainfall across the South East, Crowhurst included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first. Central London is about 50 miles from Crowhurst. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Older community buildings, The Parish Church of St George among them, often have frames of mixed ages whose mastic varies. Buildings close to stations like Crowhurst station (to the north-west of Crowhurst) are often flats over shops, with frame mastic to keep sound. Older buildings near Crowhurst, from historic houses such as Durhamford Manor (3.8 miles north of Crowhurst) to more modest stock, need compatible products when frames are resealed.
