Cost factors for mastic joints
A fixed quote reflects the actual work. It takes account of:
- Which sealant the job calls for
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Removal of failed or old sealant
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Clear photographs of the problem areas
- Access details, including height
- Your programme or deadline
- Any specification or named product

Mastic sealing in Leigh-on-Sea
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints, and the failures we are asked to look at most are open joints in brickwork or panels and communal area joints that look neglected. One point of contact handles commercial sealant work in Leigh-on-Sea from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In a smaller place such as Leigh-on-Sea, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email drawings and photos and we’ll come back to it.

Why deal with it now?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Common questions from Leigh-on-Sea clients
Does the sea air around Leigh-on-Sea change the choice of sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Will you take on a block within reach of Leigh-on-Sea station?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Block-wide mastic in Leigh-on-Sea
The sea is no more than about 1 mile from Leigh-on-Sea. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, and they deserve more regular inspection. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you are responsible for a building such as Church of St Margaret of Antioch, frame and door mastic needs the same attention as any other property. If you manage student housing near a university such as University of Essex, which lies east of Leigh-on-Sea, the summer turnaround is the time for mastic.
