When to call us in Cheriton
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Most enquiries start with one or more of the following:
- Communal area joints that look neglected
- Repeated reactive repairs to the same buildings
- Mastic failing across several blocks on an estate
- Failed external movement joints
Historic properties like Hinton Ampner House, 0.8 miles south-east of Cheriton, show the age of some local stock, where frame mastic must suit soft brick or stone.

- What site paperwork they can supply

Mastic sealing in Cheriton: the local picture
Cheriton is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 56 miles from central London, Cheriton is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
For a school such as Cheriton Primary School, perimeter mastic on windows and doors is a holiday job. Older community buildings, Church of St Michael among them, often have frames of mixed ages whose mastic varies.

Questions about Cheriton
Can one quote cover a number of our buildings near Cheriton?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Is a smaller place like Cheriton outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Cost factors for mastic joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The product specified
- How accessible the joints are
- Distance, for remote addresses
- How much there is to seal
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- When you need the work done
- What the building is and how it’s used
- The product your specification calls for
- A wide shot and a close-up of the area
For a fixed quote, call the office on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.
Diagnose, treat, sign off

You will have a fixed quote before work starts.

Related advice
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Leaks through the frame itself rather than the perimeter
- Asbestos-containing sealant, which we don’t remove
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
Joints and surfaces we work on
- External wall and movement joints
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal entrances and stairwells
Surface by surface
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
