Construction mastic in St George in the East, done properly
Mastic follows everyone else, which means it absorbs every delay upstream. 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. If you’re dealing with old sealant on a refurbishment that needs stripping before new work and caulk cracking where joints are moving more than expected, we can put it right, on cladding and panel joints, floor and skirting junctions and window and door perimeters alike. For commercial sealant work in St George in the East, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Surface by surface
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.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
What we’re called out for in St George in the East
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding, so preparation matters as much here as on a reseal.
It’s worth sending us details if you spot any of the following:
- A long mastic snag list close to completion
- Existing joints on a refurb that need cutting out and resealing
- External joints sealed in damp or cold conditions that are now failing
- Inconsistent sealant finishes from plot to plot
Recladding or extending a unit at a site like Princes Court Business Centre, less than half a mile east of St George in the East, brings panel joints and frame perimeters into the programme.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- Are they CHAS accredited or on Constructionline?
- Who will actually carry out the work
- How they’ll work around occupants
Honest limits
We check first that sealant really is the fix. It won’t put right:
- Designing joint widths or choosing the specification (that sits with the designer)
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly before you book.

With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.

- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.

When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
