Construction mastic near Writtle
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Ask cleaners to use soft cloths around fresh sealant
- Get the mastic subcontractor involved early in the programme
- Check frame gaps are within the sealant’s range before sealing
- Allow flexibility for external sealing in damp or cold weather
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. We can advise if a joint needs a different product.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.
How we handle construction mastic in Writtle
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. We work on floor and skirting junctions, sanitary and kitchen joints and internal decorators’ caulk, and the failures we are asked to look at most are a mastic package split between trades with no clear owner and frame perimeters left unsealed or poorly sealed. Most enquiries from Writtle 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.
Around places like Writtle, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Diagnose, treat, sign off
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. For a job in Writtle, the main thing is a clear picture of the work. A fixed quote follows.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work

FAQs: Writtle
Can work at a site such as Anglia Ruskin University fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Writtle too far out for you?
Not at all. Writtle is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What happens if the weather stops external sealing?
Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure so it’s better to wait.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you use the sealant named in the specification?
The specified product is what goes in. Any suggested alternative is put to you before anything changes.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
For managing agents and facilities managers
When you manage a building on behalf of an owner, 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.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
When to call us in Writtle
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
Most enquiries start with one or more of the following:
- Bath and shower joints scraped during the final clean
- Frame gaps too wide for sealant alone
- New external sealant already peeling away
- A long mastic snag list close to completion
Units on estates such as Widford Industrial Estate (1.2 miles east of Writtle) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- What level of public liability insurance do they hold?
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
- Will CSCS-carded applicators be on site?
Different surfaces, different methods
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services so we will flag where the detail needs something different. Tell us what records you need and we’ll confirm with the quote.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
Contractors’ notes for Writtle
Writtle 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. Writtle lies roughly 27 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
University estates such as Anglia Ruskin University (to the north of Writtle) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Projects at colleges like Chelmsford College - Moulsham Street Campus (to the east of Writtle) tend to run to term dates, so the mastic is planned tightly.
