About our mastic sealing in Birling Gap
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. The enquiries we see most involve mastic failing across several blocks on an estate and a mix of products and colours from past repairs, on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints. A single leaking joint is often how a building in Birling Gap first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Birling Gap, 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.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Common problems we fix in Birling Gap
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Clients normally get in touch after noticing one or more of the following:
- A mix of products and colours from past repairs
- Complaints coming in block by block
- Brittle perimeter mastic across a building
- Open joints in brickwork or panels
With historic buildings such as Alfriston Clergy House (4.7 miles north-west of Birling Gap) in the wider area, owners of older properties around Birling Gap should expect mastic to need a product that suits old masonry.
Questions to ask before you book
- How they’ll work around occupants
- Whether primer will be used where the manufacturer specifies it
- Health and safety accreditation such as CHAS
- Whether their applicators hold CSCS cards
For managing agents and facilities managers
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Why deal with it now?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Converted and older buildings near places like Birling Gap tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Mastic sealing around Birling Gap: points for this area
The sea is no more than about 1 mile from Birling Gap. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. Birling Gap sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Birling Gap: questions and answers
Does the sea air around Birling Gap change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you quote for a block close to Eastbourne station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you cover Birling Gap?
Yes. Sites across Birling Gap are covered, with one number for every area we cover.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Masonry that has broken away beside the joint
- Broken glass or failed sealed units
- Leaks through the frame itself rather than the perimeter
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Our process
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Birling Gap are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- 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
- Send any specification or drawings in advance
- Tell staff and tenants when we will be in
- Flag any permit to work we’ll need

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Advice

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
