About our mastic sealing in Martins Heron
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. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on window and door perimeters on blocks, communal kitchens and washrooms and communal entrances and stairwells, and the failures we are asked to look at most are the same joint failures repeated across a portfolio and patchy repairs in mismatched sealant. A specialist sealant contractor works differently from a general builder: in Martins Heron, that means joint design, primers and backing rod as standard.
Places the size of Martins Heron usually have some housing association stock, small blocks and mixed-use buildings. Their window perimeters and external joints need renewing as the mastic ages.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- Look at the sunniest and most exposed elevations first
- Have the asbestos survey to hand for older buildings
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Signs you need mastic sealing in Martins Heron
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
If one of these sounds familiar, it’s time for a closer look:
- Movement joints with sealant missing
- Damp patches beside frames
- Cracked, hardened mastic round windows on a block
- Draught complaints from residents or tenants
Churches, halls and community buildings such as St Paul are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Questions to ask before you book
- How joint depth will be controlled
- Can the work be phased to keep areas open?
- Is the sealant right for the movement and the substrate?
- Their pre-qualification and accreditations
Planned mastic for Martins Heron portfolios
Rainfall across the South East, Martins Heron included, is lower than in many parts of the UK. 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. The planned town of Bracknell is on Martins Heron’s doorstep. Estates from the same phase normally have mastic of the same age, so owners and associations can deal with it block by block.
Student accommodation around universities such as Imperial College Silwood Park Campus (to the east of Martins Heron) is normally managed block by block, which suits a planned mastic programme. Blocks of flats and mixed-use buildings often cluster around stations such as Martins Heron station, under half a mile to the south-west of Martins Heron, and their window and balcony mastic tends to age at the same rate across a building.
Martins Heron is about 1 mile east of Bracknell, in Bracknell Forest.

Questions we are asked in Martins Heron
We manage a building near Martins Heron station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Can you work at a site such as Bracknell Enterprise Centre, by Martins Heron?
Yes, sites like Bracknell Enterprise Centre are within our area, along with the rest of Martins Heron. Photos and a short description are enough for a first look.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- How accessible the joints are
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- The asbestos register, for older buildings
- What the building is and how it’s used
- How the joints are reached, and at what height
- Where the site is, with the postcode
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Misted or failed double-glazed units
- Water coming in from the roof or rainwater goods
- Materials that need asbestos testing before work
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

What happens if it’s left?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Small buildings around Martins Heron suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- 12-month guarantee on workmanship
- Colours confirmed for the specified product
- Colours chosen to suit frames, cladding or finishes where possible
- Failed material removed, not covered up
