Construction mastic near Great Leighs
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Why deal with it now?
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility, with the same standard on every plot. Around Great Leighs, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Construction mastic in Great Leighs, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over. Sealing too early only means coming back once others have damaged it. Most enquiries involve a long mastic snag list close to completion and oversized or tapered gaps around new frames, across sanitary and kitchen joints, internal decorators’ caulk and window and door perimeters. A specialist sealant contractor works differently from a general builder: in Great Leighs, that means joint design, primers and backing rod as standard.
For a site near Great Leighs, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
What sets the cost
We price every job individually. The things that drive the figure:
- Any access equipment needed
- Joint width, depth and condition
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- The type of building and who uses it
- Any specification or named product
- Drawings or a marked-up plan, if available
- How the joints are reached, and at what height
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Your questions answered
Can you work at a site such as Banters Lane Business Park, by Great Leighs?
Yes, sites like Banters Lane Business Park are within our area, along with the rest of Great Leighs. A few photographs and the unit address let us price the work.
Do you take on work at healthcare sites like William Julien Courtauld Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Can you work to our specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.
What happens if old sealant might contain asbestos?
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.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
What we’re called out for in Great Leighs
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
Typical triggers for a call:
- Caulk cracking where joints are moving more than expected
- Failed sealant in an existing building being refurbished
- New external sealant already peeling away
- Snag items on joints that need redoing before handover
When a school such as Great Leighs Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How they’ll work around occupants
- The named product and why it was chosen

Honest limits
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.
