When to call us in Foscot
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
Look out for the following:
- Brittle perimeter mastic across a building
- Estate-wide sealant that is simply worn out
- Draughts at frames across a block
- Damaged joints in communal entrances and corridors
Landlords with units on estates such as Wychwood Business Centre, 3 miles south-east of Foscot, can bring frame, door and external mastic across several units into one programme.

Mastic sealing for commercial buildings in Foscot
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. We work on external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms, and what we’re called in for most is draughts at frames across a block and failed external movement joints. Looking for mastic applicators who cover Foscot? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
In and around smaller places like Foscot, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Common questions from Foscot clients
Can you work at a site such as Wychwood Business Centre, by Foscot?

Can you quote for a block close to Kingham station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Do you cover Foscot?
Yes. Foscot is in our area and the rest of Oxfordshire, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or email drawings and photos.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Blocks and managed buildings in Foscot
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
For a school such as Bledington Primary School, perimeter mastic on windows and doors is a holiday job. Older buildings near Foscot, from historic houses such as Chastleton House (to the north of Foscot) to more modest stock, need compatible products when frames are resealed.

Other services in Foscot
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Different surfaces, different methods
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Mention RAMS, insurance or CSCS requirements up front
- Make mastic part of routine maintenance checks
- Encourage occupiers to report problems at frames
- Plan resealing building by building rather than complaint by complaint
Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
