Facade sealing in Coscote
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. We work on shopfront frames, stone and brick facade joints and coping and flashing joints, and what we are called in for most is leaks at window and door perimeters and old perimeter mastic that has dried out. Whoever orders the work in Coscote, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Coscote is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Common problems we fix in Coscote
When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Most enquiries start with something like this:
- Previous reseals run over old sealant
- Air leaks through failed facade joints
- Sealant pulling away from frames or panels
- Failed seals around shopfront and entrance frames
Historic houses such as Brightwell Manor, 4.1 miles to the east of Coscote, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Site staff or a sealant specialist?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Facades, frames and programmes in Coscote
Coscote is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Coscote lies roughly 50 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
Recladding or extending a unit at a site like Market Place Shopping Centre, 1.3 miles north-east of Coscote, brings panel joints and frame perimeters into the programme. Work at a hotel such as The Kingswell Hotel, 1.1 miles west of Coscote, tends to be programmed around bookings, mastic included.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Joints whose design needs changing by the specifier
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Specialist high-level access methods
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.
What we seal
- Stone and brick facade joints
- Cladding panel joints
- Shopfront frames
- Coping and flashing joints
- Window and door perimeters
- Perimeter joints where frames meet the structure
How the job changes by surface
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, with masked edges for a clean line.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair before sealing.
Common questions from Coscote clients
Is hospital work, at somewhere like Didcot Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Coscote outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Coscote need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Flag any permit to work we will need
- Agree which areas must stay open
Ask for a quote
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email a schedule or drawings.
Advice
After the work
A few simple habits keep the new joints working:
- Record the product and colour used on each elevation
- Confirm the survey covers external sealants in older buildings
- Avoid patch repairs on failed facade joints
- Inspect facade joints on a regular cycle
Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
