Mastic sealing around Greensted Green: how the place shapes the job
Central London is about 19 miles from Greensted Green. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Older community buildings, Greensted Church among them, often have frames of mixed ages whose mastic varies. Site managers at schools like The Ongar Academy can fit frame mastic into the summer works.

Mastic sealing in Greensted Green
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on external wall and movement joints, window and door perimeters on blocks and balcony and threshold joints, and the failures we are asked to look at most are window mastic that has split and shrunk and the same joint failures repeated across a portfolio. Facilities teams, main contractors and managing agents in Greensted Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For buildings around smaller places like Greensted Green, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Greensted Green
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Converted and older buildings near places like Greensted Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
A quote for mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

When something else is needed

- Water coming in from the roof or rainwater goods
- Misted or failed double-glazed units
- Asbestos-containing sealant, which we don’t remove
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.

Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

- Estate-wide sealant that is simply worn out

Greensted Green: questions and answers
Will you take on work at estates like North Weald Industrial Estate, close to Greensted Green?
Yes, sites like North Weald Industrial Estate are within our area, along with the rest of Greensted Green. Send details of the unit and the work through our quote form for a quick quote.
Will you price a mastic programme across our Greensted Green portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
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, so we will confirm the curing time on the day.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is asbestos a concern with old mastic?
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 work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
