Construction mastic for Brasted sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
How we handle construction mastic in Brasted
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you are dealing with window and door perimeters that won’t pass inspection and sealant knocked or painted over by other trades, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Brasted it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a site near Brasted, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Do you need construction mastic in Brasted?
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.
Things that typically lead to an enquiry:
- Caulk cracking where joints are moving more than expected
- Missed perimeter joints on a new elevation
- Bath and shower joints scraped during the final clean
- Old sealant on a refurbishment that needs stripping before new work
When a school such as Combe Bank School is extended or refurbished, the mastic package is often squeezed into the holidays.
What your quote should include
- Will CSCS-carded applicators be on site?
- Do they follow the manufacturer’s priming guidance?
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS

- Defective windows, doors or glazing units (the supplier or installer’s job)
