How we handle mastic sealing in The Green
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. Most enquiries involve a mix of products and colours from past repairs and water getting in round frames after rain, on external wall and movement joints, communal entrances and stairwells and communal kitchens and washrooms. Most enquiries from The Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as The Green tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
A 12-month guarantee applies to all our work in Essex. Should something we installed fail, speak to us on 01277 525 020 or email us and we will come back to it.

Common problems we fix in The Green
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
If one of these sounds familiar, it’s time for a closer look:
- Movement joints with sealant missing
- Complaints coming in block by block
- Damaged joints in communal entrances and corridors
- Cracked, hardened mastic round windows on a block
Property owners at sites such as Lanham Business Park, 1.8 miles to the north-east of The Green, can have mastic renewed between lettings.
Before you book anyone
- Their pre-qualification and accreditations
- How they’ll work around occupants
- Which product they’ll use, and why it suits the joint
- Proof of insurance
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Glazing that needs replacing
- Substrate edges that need repairing first
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly.
What we seal
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
Why deal with it now?
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. For buildings around smaller places like The Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
Why us?
- 12 months’ guarantee on every job
- Work to your specification and the manufacturer’s guidance
- Old sealant cut out, never sealed over
- Public liability insurance in place

Mastic sealing in The Green: the local picture
The Green lies roughly 37 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. The Green 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 normally where frame mastic ages first.
Trustees of buildings like St Barnabas can bring frame and external mastic into a planned maintenance list. If you look after a block within reach of Cressing station, which lies north-east of The Green, frame and balcony mastic can be renewed on one programme.
The Green is about 3 miles south of Braintree, in Essex. We send applicators to The Green for mastic joints, handled exactly as we handle every other area. Across Essex, 644 places are covered, including The Green. Sites around London have their own page, roughly 37 miles from The Green.

Landmarks near The Green
Around The Green, our work takes us to commercial buildings near Braintree Sixth Form and The Plough pub. The Green’s nearest station is Cressing station, roughly 0.5 miles north-east. Nearby you will also find William Julien Courtauld Hospital (2.4 miles north-west) and Cressing Temple (1.7 miles east). The countryside around The Green includes Sandylay and Moat Woods.
When to bring in a specialist
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Common questions from The Green clients
Do you cover business parks and estates near The Green, such as Lanham Business Park?
Yes. Estates, retail parks and business parks around The Green, Lanham Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Is The Green too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photos or drawings if you have them.
On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near The Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- 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.
- We check the finished work and confirm the guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- Tell us your opening times and when work is allowed
