Should maintenance staff do it?
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.
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.
Mastic sealing in Hailsham
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. Site teams most often ask us about leaks at window and door perimeters and open joints in brickwork or panels, on balcony and threshold joints, external wall and movement joints and shopfronts below residential blocks. Whoever orders the work in Hailsham, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Housing associations in towns like Hailsham often run planned maintenance by estate or by block. Work can move block by block, with you handling resident notices.
Our workmanship is guaranteed for 12 months, in Hailsham as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Common problems we fix in Hailsham
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
Typical triggers for a call:
- Communal area joints that look neglected
- Window mastic that has split and shrunk
- Estate-wide sealant that is simply worn out
- A mix of products and colours from past repairs
Historic properties like Horselunges Manor, 1.5 miles north of Hailsham, show the age of some local stock, where frame mastic must suit soft brick or stone.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Look at the sunniest and most exposed elevations first
- Track which buildings were done and when
- Check the asbestos register before any old mastic is disturbed
- Ask residents or tenants to report leaks and draughts early
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
From enquiry to sign-off
Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Most work in Hailsham is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.
- 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.
Before we start on site
- Tell us which areas need to stay in use
- Share the asbestos register for older buildings
- Flag any permit to work we’ll need

Common questions from Hailsham clients
We manage a building near Polegate station. Can you help?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you take on block-wide or estate-wide mastic work in Hailsham?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
What about access for upper-floor joints?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you work in Hailsham?
Yes. Sites across Hailsham are covered, and the same phone number covers every area.
Different surfaces, different methods
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Planned mastic for Hailsham portfolios
Hailsham is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Hailsham is about 46 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.
If you own or manage units on a site such as Crown Close Industrial Estate, which lies south-west of Hailsham, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. For agents with blocks near Polegate station, which lies south of Hailsham, a block-wide mastic programme deals with frames, balconies and entrances in one go.
