The enquiries we see most involve mastic failing across several blocks on an estate and a mix of products and colours from past repairs, across communal entrances and stairwells, communal kitchens and washrooms and shopfronts below residential blocks.

Rural conversions near places like Finkley 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.

Frames, entrances and external joints in Finkley
Central London is about 61 miles from Finkley. 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. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Buildings close to stations like Andover station (2.4 miles south-west of Finkley) are often flats over shops, with frame mastic to keep sound. If your remit includes a building such as Smannell and Enham Church of England (Aided) Primary School, frame and door mastic can be programmed for the holidays.

What’s near Finkley

After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- List the paperwork your organisation requires when you send details
- Look at the sunniest and most exposed elevations first
- Keep a record of when each building was resealed
- Check sealant joints during planned building inspections
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
How the job changes by surface
Tenement and older buildings
Stone needs a neutral-cure product and we choose accordingly.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Common questions from Finkley clients
Is Walworth Business Park, near Finkley, within your area?
Yes, sites like Walworth Business Park are within our area, along with the rest of Finkley. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you quote for a block close to Andover station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so there are no surprises.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Masonry that has broken away beside the joint
- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Do you need mastic sealing in Finkley?
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Typical triggers for a call:
- Patchy repairs in mismatched sealant
- Repeated reactive repairs to the same buildings
- Cracked, hardened mastic round windows on a block
- Draughts at frames across a block
Property owners at sites such as Walworth Business Park, 1.2 miles to the south of Finkley, can have mastic renewed between lettings.
What to look for in a quote

- The named product and why it was chosen
