How we handle construction mastic in Chignall St James
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Chignall St James, send drawings and the specification through our quote form. We work on sanitary and kitchen joints, window and door perimeters and brick and block movement joints, and what we’re called in for most is old sealant on a refurbishment that needs stripping before new work and sanitary sealant damaged by following trades. Most enquiries from Chignall St James 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.
Sites around smaller places like Chignall St James can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.
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.

What the job involves on each surface
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
Contractors’ notes for Chignall St James
Central London is about 29 miles from Chignall St James. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Chignall St James is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
When units on a site such as Rivermead Industrial Estate, 2.5 miles south-east of Chignall St James, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For a contractor working at a hospital such as Broomfield Hospital (2 miles north-east of Chignall St James), perimeter and facade sealing is planned around patients and deliveries. School extensions, at buildings such as Newlands Spring Primary School, typically run to the summer holidays, mastic included.

Common questions from Chignall St James clients
Is Rivermead Industrial Estate, near Chignall St James, within your area?
Yes. Our area takes in Chignall St James and its surroundings, with estates and business parks such as Rivermead Industrial Estate included. Photos and a short description are enough for a first look.
Can you work around term dates at a campus such as Anglia Ruskin University?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Will you stick to the specified products?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
When to bring in a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Specifying the product where the designer hasn’t
- Joints damaged after sign-off by following trades
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly before you book.
What we seal
- Window and door perimeters
- Sanitary and kitchen joints

Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Chignall St James are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Share your working hours and any access restrictions
- Arrange parking or a loading space
