When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
- Defective windows, doors or glazing units (the supplier or installer’s job)
If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think.

Construction mastic in Catford
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal areas can usually carry on while the outside waits. If you are dealing with mastic snags holding up handover and oversized or tapered gaps around new frames, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Catford, preparation and product choice get the time they need.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
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.

Why it’s worth doing now in Catford
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Leave it late and they turn up on the snag list. In Catford, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

When to call us in Catford
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
What tends to prompt an enquiry:
- External joints sealed in damp or cold conditions that are now failing
- Existing joints on a refurb that need cutting out and resealing
- Oversized or tapered gaps around new frames
- Window and door perimeters that won’t pass inspection
For contractors refurbishing units at places like Bell Green Retail Park (1 mile south-west of Catford), the mastic covers cladding panels, roller-door and window perimeters.

What else we do in Catford
Construction mastic in Catford: the local picture
Several hotels sit less than 2 miles from Catford. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Site traffic in Catford falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
University estates such as University of Greenwich - Greenwich Campus (2.8 miles north of Catford) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Hospital estates such as University Hospital Lewisham (0.9 miles north of Catford) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

FAQs: Catford
Can you work on a hospital site such as University Hospital Lewisham?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does your area include sites such as Bell Green Retail Park, near Catford?
Yes. We cover Catford and the area around it, including industrial estates, business parks and retail parks such as Bell Green Retail Park. A few photographs and the unit address let us price the work.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Do you do fire-rated sealing on new builds?
It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.
Do you cover Catford?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
From enquiry to sign-off
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area.

- We price from the drawings, specification and programme you send.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Get the mastic subcontractor involved early in the programme
- Don’t force external sealing on a damp or frosty day
- Release areas for mastic once other trades have finished in them
- Keep product details for future maintenance
Any damage after we’ve finished should go on the snag list right away. Snags can be picked up in a planned close-out visit.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.
