Your questions answered
Can you work on a hospital site such as Broomfield Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can work at a site such as Anglia Ruskin University fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you do internal caulk as well as external mastic?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging, all priced as one package.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can fire-rated sealing at service penetrations be included?
We install fire-rated sealant where it is the specified product. If the detail calls for collars, wraps or batts instead, we’ll tell you.
Do you use the sealant named in the specification?
We use the product the specification names. Any suggested alternative is put to you before anything changes.

Different surfaces, different methods
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies, and seal only with a dry joint inside the product’s temperature range.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere following the programme.
Building and refurbishing in Chignall Smealy
Chignall Smealy sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Chignall Smealy is about 29 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.
School extensions, at buildings such as Newlands Spring Primary School, usually run to the summer holidays, mastic included. New wings at hospitals like Broomfield Hospital (to the east of Chignall Smealy) bring long runs of window and panel joints to seal. Older buildings in the area around Chignall Smealy, such as Hylands, 4.7 miles to the south of Chignall Smealy, need care when sealed: the product has to suit soft or historic materials.

Maintenance after handover
Once the work is signed off, these steps help:
- Record the products used in the O&M file
- Brief following trades on areas that have been sealed
- Don’t schedule sealing before decorators and flooring are done
- Get the mastic subcontractor involved early in the programme
A new structure shifts as it loses construction moisture. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. We can advise if a joint needs a different product.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Why act early in Chignall Smealy
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. We can run snagging as its own phase before handover. Older rural buildings around Chignall Smealy move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
