What sets the cost
To price the job, we consider:
- Which sealant the job calls for
- Working within restricted access windows
- Travel to remote or island sites
- The site’s rules and procedures
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What to include in your enquiry
We can often quote from photographs and a few details. It helps to include:

- The site address and postcode
- Access details, including height
- Rough lengths or quantities, or drawings if you have them
For a fixed quote, give us a call on 01277 525 020 or email drawings and photos with the site address and an outline of the work. Our quote form is another easy route.
Mastic sealing in The Platt
Across The Platt and the rest of East Sussex, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you have water getting in round frames after rain and cracked, hardened mastic round windows on a block, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in The Platt, that means joint design, primers and backing rod as standard.
In and around smaller places like The Platt, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

For owners and agents in The Platt
Central London is about 33 miles from The Platt. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. The Platt is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
For a school such as Frant Church of England Primary School, perimeter mastic on windows and doors is a holiday job. Landlords with units on estates such as Durgates Industrial Estate, 2.8 miles to the south-east of The Platt, can bring frame, door and external mastic across several units into one programme.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Do you need mastic sealing in The Platt?
The edges of the material itself sometimes break away for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Things that usually lead to an enquiry:
- Worn sealant at communal door frames
- No planned programme for sealant
- Failed external movement joints
- Patchy repairs in mismatched sealant
If you manage student housing near a university such as Canterbury Christ Church University - Salomons (4.9 miles north of The Platt), the summer turnaround is the time for mastic.
