About our mastic sealing in Mersham
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on communal entrances and stairwells, external wall and movement joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are leaks at window and door perimeters and draughts at frames across a block. Searching for sealant specialists in Mersham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around smaller places like Mersham, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why act early in Mersham
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Converted and older buildings near places like Mersham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Different surfaces, different methods
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.
Window and door perimeters on blocks
We usually work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
- Substrate edges that need repairing first
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Surfaces we seal
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Balcony and threshold joints
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
Looking after buildings in and around Mersham
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first. At about 52 miles from central London, Mersham is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
If you’re responsible for a building such as Church of St John the Baptist, frame and door mastic needs the same attention as any other property. Schools and community buildings such as Mersham Primary School need frame and external mastic kept sound like any building.

Mersham: questions and answers
Do you cover business parks and estates near Mersham, such as Mersham-le-Hatch Business Village?

Is Mersham too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you work for managing agents and housing associations?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Do you need mastic sealing in Mersham?
Frames, panels and masonry expand and contract through the year, 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 long before it should.
Look out for the following:
- No planned programme for sealant
- Estate-wide sealant that is simply worn out
- Window mastic that has split and shrunk
- Open joints in brickwork or panels
Blocks of flats and mixed-use buildings often cluster around stations such as Ashford International station (2.9 miles north-west of Mersham) and their window and balcony mastic tends to age at the same rate across a building.
