Construction mastic in The Green
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How the job changes by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room, cutting out damaged joints and resealing them properly.
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies and work only when conditions suit.
How we handle construction mastic in The Green
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. We seal so the snag list stays short. If you have frame gaps too wide for sealant alone and external joints sealed in damp or cold conditions that are now failing, we can help. A specialist sealant contractor works differently from a general builder: on jobs in The Green, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as The Green bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Designing joint widths or choosing the specification (that sits with the designer)
- Frame gaps too wide for sealant, which the installer needs to correct
- Approving fire stopping as compliant
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Surfaces we seal
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Cladding and panel joints
- Brick and block movement joints
- Floor and skirting junctions
- Window and door perimeters
What sets the cost
Before we quote, we look at:
- Whether old sealant has to be cut out first
- The product specified
- Location, for remote and island sites
- Backing rod, priming and other preparation
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- Your programme or deadline
- The postcode of the building
- Specification clauses that apply
- A wide shot and a close-up of the area

Building and refurbishing in The Green
At about 37 miles from central London, The Green is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. The Green sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
Projects at schools like Cressing Primary School work to term dates, so mastic is programmed tightly. Extensions at sites like Braintree Community Hospital (to the north-west of The Green) typically sit beside working departments, and the mastic follows strict access rules.
The Green is about 3 miles south of Braintree, in Essex. Any commercial site in The Green is covered, whether it’s a single job or part of a planned programme. We work across 644 places in Essex, large and small. Sites around London have their own page, roughly 37 miles from The Green.
Work on mastic packages is covered throughout CM8, for business premises of every kind. If your building is just outside The Green, we cover Black Notley (1 mile north-west), Tye Green (1 mile north-east), Hawbush Green (1 mile north-east), White Notley (1 mile south-east) and Long Green (1 mile north-east). Nearby towns on our patch include Colchester (14 miles east), Chelmsford (8 miles south-west), Braintree (3 miles north), Maldon (9 miles south-east), Witham (4 miles south-east) and Camulodunum (13 miles east).

Well-known places in the area include 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.
Signs you need construction mastic in The Green
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- Missed perimeter joints on a new elevation
- Failed sealant in an existing building being refurbished
- Different trades sealing to different standards
- Mastic snags holding up handover
Units on estates such as Lanham Business Park (1.8 miles north-east of The Green) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Before you book anyone
- Will RAMS and insurance details be available?
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
- Will CSCS-carded applicators be on site?
Your questions answered
Will you take on work at estates like Lanham Business Park, close to The Green?
Yes. Estates, retail parks and business parks around The Green, Lanham Business Park among them, are all within reach. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Is The Green too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email the details over. Include photographs or drawings if you have them.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do you work with the site programme?
Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Do you do fire-rated sealing on new builds?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
