Construction mastic in Hamsey Green, done properly
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, and we are fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you have oversized or tapered gaps around new frames and cracks opening in caulked internal joints, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Hamsey Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in a London area such as Hamsey Green means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Hamsey Green
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Leave it late and they turn up on the snag list. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Why appoint us
- Standard and matched colours in many product ranges
- Constructionline member for supplier checks
- 12-month guarantee on workmanship
- Colour agreed before work starts

What the job involves on each surface
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting.
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.
Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Drawings, the sealant specification and your programme come to us for pricing.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site

- Warn occupants and staff about the work

Related advice
After the work
Regular inspection catches problems early. Specifically:
- Ask cleaners to use soft cloths around fresh sealant
- Ask installers to correct oversized gaps first
- Ask for joint and product checks before the package is urgent
- Bring the mastic contractor in after the last trades are through
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement. We can advise if a joint needs a different product.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.
Your questions answered
Can you work around term dates at a campus such as John Ruskin College?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on jobs in Hamsey Green where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Can one quote cover more than one building?
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.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
When to call us in Hamsey Green
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
If one of these sounds familiar, it’s time for a closer look:
- Early adhesion failures on new external joints
- Sealant knocked or painted over by other trades
- Existing joints on a refurb that need cutting out and resealing
- Window and door perimeters that won’t pass inspection
When a school such as Hamsey Green Primary is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- Their pre-qualification and accreditations
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
- How the existing material will be dealt with
