Mastic sealing in Hastings
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you have the same joint failures repeated across a portfolio and leaks at window and door perimeters, we can help. For commercial sealant work in Hastings, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Town-centre blocks over shops in places like Hastings have frames, balconies and communal entrances with mastic to maintain. A failed joint can let water into a flat or the unit below, so it pays to renew mastic before it leaks.
Every job we finish is backed by a 12-month workmanship guarantee, in Hastings as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?
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. In a town the size of Hastings, traffic, footfall and weather keep working on a failed joint. Catching it early keeps the fix simple.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
Why appoint us
- CHAS accredited

What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Glazing that needs replacing
- Materials that need asbestos testing before work
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Commercial clients in Hastings
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Hastings can form part of a wider programme across East Sussex.
CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. For premises in central Hastings, deliveries and parking need a bit of planning, whereas edge-of-town units normally have yard space. Let us know what’s there when you send details.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- Make sure the joints can be reached

Different surfaces, different methods

Consistent products and colours across an estate make future maintenance simpler and easier to manage.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
Hastings: questions and answers
Do you work for managing agents with blocks near St Leonards Warrior Square station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Can being near the sea in Hastings affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Do you cover Hastings?
Yes. Sites across Hastings are covered, with one number for every area we cover.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you do block-wide mastic programmes?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
