What we’re called out for in Henhurst
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
What tends to prompt an enquiry:
- Damaged joints in communal entrances and corridors
- Repeated reactive repairs to the same buildings
- Cracked, hardened mastic round windows on a block
- Movement joints with sealant missing
For owners of several units at places like Lion Business Park, 2.6 miles north of Henhurst, one programme can deal with frame and external mastic across the lot.
Before you book anyone

- Which product they’ll use, and why it suits the joint
- How joint depth will be controlled
- Health and safety accreditation such as CHAS
Mastic sealing in Henhurst
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have window mastic that has split and shrunk and draughts at frames across a block, we can help, on communal kitchens and washrooms, balcony and threshold joints and shopfronts below residential blocks alike.

For owners with a single building near Henhurst, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Looking after the joints
Regular inspection catches problems early. In particular:
- Keep bins and bikes away from communal door frames
- Look at the sunniest and most exposed elevations first
- Make mastic part of routine maintenance checks
- Encourage occupiers to report problems at frames
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
On site: what to expect
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. For work around Henhurst, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

FAQs: Henhurst
Will you take on work at estates like Lion Business Park, close to Henhurst?
Yes. We cover Henhurst and the area around it, including industrial estates, business parks and retail parks such as Lion Business Park. Send details of the unit and the work through our quote form for a quick quote.
Is Henhurst off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Do you work for managing agents and housing associations?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
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.
Commercial and mixed-use buildings
Commercial occupiers usually stay open during the work, so we plan around them.

Central London is about 22 miles from Henhurst. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Historic properties like Cobham College, 1 mile south-east of Henhurst, show the age of some local stock, where frame mastic must suit soft brick or stone. Older community buildings, Church of St Margaret among them, often have frames of mixed ages whose mastic varies.
