About our external mastic in Burcott
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Typical jobs include joints with sealant missing in places and water getting into walls through failed joints, on brickwork movement joints, concrete & block and copings & trims.
Around Burcott, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
You get a 12-month guarantee, the same in Burcott as everywhere else we work.

Landlord and commercial work in Burcott
For anyone letting property in or around Burcott, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Common problems we fix in Burcott
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Common reasons people contact us are:
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
Schools such as Bierton Church of England Combined School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- How long the guarantee is
- How the colour is chosen
- How long to leave it before use
What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Subsidence or other structural problems
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal

What the job involves on each surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and protects the render itself.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.

Burcott buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St James include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Aylesbury station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Burcott, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
