Block-wide mastic in Dummer
Dummer lies roughly 50 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Dummer sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
If you look after a block within reach of Micheldever station, 4.8 miles south-west of Dummer, frame and balcony mastic can be renewed on one programme.

What else we do in Dummer
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Leaks from above rather than through a joint
- Leaks through the frame itself rather than the perimeter
- Glazing that needs replacing
If you’re not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.
Where we work in Dummer

When to call us in Dummer
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
These are often picked up first by site or facilities staff:
- Mastic failing across several blocks on an estate
- Open joints in brickwork or panels
- Window mastic that has split and shrunk
- Draughts at frames across a block
Older community buildings, Church of All Saints among them, often have frames of mixed ages whose mastic varies.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The named product and why it was chosen
- Can the work be phased to keep areas open?
- What site paperwork they can supply
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Dummer are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
What we need from you
- Send any specification or drawings in advance
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
Advice
Surface by surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
FAQs: Dummer
Will you take on a block within reach of Micheldever station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Can you quote for mastic across several buildings in and around Dummer?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
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 checks let you plan resealing before leaks or damage.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
Leave it or put it right?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Older rural buildings around Dummer move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
