Construction mastic for commercial buildings in Eastbury
We work to the specification and the programme rather than whatever product is to hand. If a product is named, that’s what goes in. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. The enquiries we see most involve old sealant on a refurbishment that needs stripping before new work and missed perimeter joints on a new elevation, across floor and skirting junctions, cladding and panel joints and sanitary and kitchen joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Eastbury is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like Eastbury, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Travel to remote or island sites
- The total length or number of joints
- Joint width, depth and condition
- How much existing material needs removing
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 few photos plus some basic facts will normally do. It helps to include:
- What the building is and how it’s used
- Clear photographs of the problem areas
- Whether an asbestos survey exists
- Your programme or deadline
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Common questions from Eastbury clients
Is Eastbury too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can the mastic package for our job in Eastbury follow the site programme?
Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you do fire-rated sealing on new builds?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. Fire-stopping design and sign-off sit with the designer and building control.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we will set out a timescale with the quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Is the mastic package guaranteed?
Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.
How the job changes by surface
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.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification.
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Eastbury can be grouped with others nearby.

Advice
What happens if it’s left?
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area typically clears more for less disruption. We can run snagging as its own phase before handover. Converted and older buildings near places like Eastbury tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

Common problems we fix in Eastbury
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge. We flag them early rather than filling them with sealant that won’t last.
What tends to prompt an enquiry:
- Frame perimeters left unsealed or poorly sealed
- Existing joints on a refurb that need cutting out and resealing
- External joints sealed in damp or cold conditions that are now failing
- Frame gaps too wide for sealant alone
For contractors building in or near Eastbury, we seal to the drawings, the specification and the programme.

Contractors’ notes for Eastbury
Eastbury 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, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 60 miles from Eastbury. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
A facade joint near Eastbury lasts when width, depth and backing are right, not just the finish.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
