For owners and agents in Duddleswell
Duddleswell 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 elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Duddleswell is about 33 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Around Duddleswell, a planned programme renews failed mastic across a building or estate in one go.

How we handle mastic sealing in Duddleswell
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you are dealing with brittle perimeter mastic across a building and old repairs sealed over failed mastic, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Duddleswell tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Duddleswell, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. Halls, stores and units around places like Duddleswell may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Why clients in Duddleswell choose us

Duddleswell: questions and answers
Can you quote for mastic across several buildings in and around Duddleswell?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Is Duddleswell too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Building owners, agents and FMs in Duddleswell
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Common problems we fix in Duddleswell
The edges of the material itself sometimes break away for example where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.
Typical triggers for a call:
- Draught complaints from residents or tenants
- Communal area joints that look neglected
- Movement joints with sealant missing
- Leaks at window and door perimeters
Buildings close to stations like Buxted station (3.8 miles south-east of Duddleswell) are often flats over shops, with frame mastic to keep sound.
What your quote should include
- Their pre-qualification and accreditations
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
- Do they follow the manufacturer’s priming guidance?
Looking after the joints
After handover, these steps help:
- Protect low-level joints in entrances
- Check sealant joints during planned building inspections
- Encourage occupiers to report problems at frames
- Avoid piecemeal callouts where you can
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.

From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Duddleswell are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Share the asbestos register for older buildings
- Send your site hours and access windows
- Move anything stored against the joints
