Common questions from Old Heathfield clients
Is Old Heathfield too far out for you?
No. Places such as Old Heathfield are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on block-wide or estate-wide mastic work in Old Heathfield?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
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.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Mastic sealing in Old Heathfield
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Old Heathfield carry our 12-month guarantee. We work on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells, and what we’re called in for most is draught complaints from residents or tenants and movement joints with sealant missing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Old Heathfield is the same: the right product in a properly prepared joint.
For owners with a single building near Old Heathfield, we plan to finish in one visit where possible. Send photos of the frames and joints and we will give a fixed quote.
The 12-month guarantee is for workmanship rather than 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.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
After the work
After handover, a little attention goes a long way:
- Log resealing dates block by block
- Start inspections with the most exposed faces
- Ask residents or tenants to report leaks and draughts early
- Have the asbestos survey to hand for older buildings
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Looking after buildings in and around Old Heathfield
At about 40 miles from central London, Old Heathfield is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Rainfall across the South East, Old Heathfield included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Churches, halls and community buildings such as The Parish Church of All Saints are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For owners of several units at places like Ghyll Road Industrial Estate, which lies west of Old Heathfield, one programme can deal with frame and external mastic across the lot.
Old Heathfield is about 7 miles north of Hailsham, in East Sussex. We send applicators to Old Heathfield for mastic joints, handled exactly as we handle every other area.

Honest limits
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Glazing that needs replacing
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

When to call us in Old Heathfield
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Clients usually get in touch after noticing one or more of the following:
- Open joints in brickwork or panels
- Draught complaints from residents or tenants
- A mix of products and colours from past repairs
- Complaints coming in block by block
If your remit includes a building such as Heathfield Community College, frame and door mastic can be programmed for the holidays.
