How we handle expansion joint sealing in Chignall St James
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on podiums and floor movement joints, precast concrete panel joints and brickwork movement joints, and the usual reasons a site gets in touch are hardened, cracked sealant on exposed facades and arrises breaking up along floor joints. A specialist sealant contractor works differently from a general builder: in Chignall St James, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Chignall St James have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Questions about Chignall St James
Can you work at a site such as Rivermead Industrial Estate, by Chignall St James?
Yes. Estates, retail parks and business parks around Chignall St James, Rivermead Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Is hospital work, at somewhere like Broomfield Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is colour matching possible?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
What’s the difference between an expansion joint and a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably and the way they’re sealed is similar.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Chignall St James need work, visits can be combined. You will have a fixed quote before work starts.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000
- Send your site hours and access windows
Quotes
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.
Related advice
What we’re called out for in Chignall St James
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
Common reasons buildings call us in:
- Sealant peeling off one face of the joint
- Torn sealant in brick or block movement joints
- Rain penetration at brick or block movement joints
- Leaks through car park deck joints onto the level below
Campuses like Anglia Ruskin University (to the south of Chignall St James) mix old and new buildings, with movement joints wherever they meet.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Concrete or masonry repairs along the arrises
- Joints too narrow for the movement, which need redesigning by the engineer
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.
What we seal
- Precast concrete panel joints
- Podiums and floor movement joints
- Brickwork movement joints
- Cladding panel joints
- Blockwork control joints
- Car park decks and ramps
What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed and we will tell you honestly. Around Chignall St James, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
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.

What the job involves on each surface
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
