Mastic sealing in Sandford St Martin, done properly
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. The enquiries we see most involve brittle perimeter mastic across a building and open joints in brickwork or panels, across external wall and movement joints, communal kitchens and washrooms and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, in Sandford St Martin it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For owners with a single building near Sandford St Martin, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Leaks from above rather than through a joint
- Frames that are rotten, warped or broken
- Asbestos-containing sealant, which we don’t remove
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.
What we seal
- Shopfronts below residential blocks
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- External wall and movement joints
Signs you need mastic sealing in Sandford St Martin
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
What tends to prompt an enquiry:
- Repeated reactive repairs to the same buildings
- Communal area joints that look neglected
- Draught complaints from residents or tenants
- A mix of products and colours from past repairs
Churches, halls and community buildings such as Church of St Martin are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Related advice
Site staff or a sealant specialist?
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.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Questions about Sandford St Martin
Is Sandford St Martin too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you cover business parks and estates near Sandford St Martin, such as Enstone Airfield Industrial Estate?
Yes, sites like Enstone Airfield Industrial Estate are within our area, along with the rest of Sandford St Martin. Photos and a short description are enough for a first look.
What paperwork can you provide?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. Converted and older buildings near places like Sandford St Martin tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
A quote for mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
Why us?

- Our applicators hold CSCS cards
