Mastic sealing for Wannock sites

Mastic sealing in Wannock, done properly
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. Removing asbestos-containing material isn’t something we do. We work on communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are open joints in brickwork or panels and the same joint failures repeated across a portfolio. Whoever orders the work in Wannock, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Wannock, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Work we carry out in East Sussex comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we will come back to it.

Your questions answered
Is Chaucer Industrial Estate, near Wannock, within your area?
Yes, sites like Chaucer Industrial Estate are within our area, along with the rest of Wannock. Send details of the unit and the work through our quote form for a quick quote.
Is Wannock too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
After the work
For the best life from the joints:
- Include mastic in your cyclical inspections
- Mention RAMS, insurance or CSCS requirements up front
- Avoid piecemeal callouts where you can
- Check the asbestos register before any old mastic is disturbed
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.
Frames, entrances and external joints in Wannock
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Central London is about 50 miles from Wannock. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.
Trustees of buildings like St Wilfrid can bring frame and external mastic into a planned maintenance list. Site managers at schools like Willingdon Community School can fit frame mastic into the summer works. If you look after a block within reach of Polegate station, 0.8 miles to the north-east of Wannock, frame and balcony mastic can be renewed on one programme.
Wannock is about 3 miles north-west of Eastbourne, in East Sussex. Wannock sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Wannock is one of 308 places in East Sussex on our list for mastic joints. We also cover Brighton, around 16 miles from Wannock.
Commercial sites across BN26 are covered. Buildings on Wannock Road, Lancing Way and Mortimer Gardens are within our area for mastic joints. Sites close to Wannock are covered too, including Lower Willingdon (1 mile south-east), Filching (1 mile south-west), Polegate (1 mile north-east), Folkington (1 mile west) and Willingdon (1 mile south-east).

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Building owners and managing agents use us on everything from one building to a spread of sites around Wannock. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Why act early in Wannock
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Halls, stores and units around places like Wannock may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Broken glass or failed sealed units
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly.
