About our construction mastic in West Dulwich
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve snag items on joints that need redoing before handover and perimeter gaps outside the sealant’s range, across internal decorators’ caulk, window and door perimeters and floor and skirting junctions. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in West Dulwich is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around West Dulwich, as across London, much of the work is refurbishing existing buildings as well as building new ones. 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.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Mastic packages on West Dulwich sites
The ULEZ covers the whole of Greater London, West Dulwich included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed. A 2-mile radius around West Dulwich takes in a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
On a campus such as King's College London, 2.5 miles to the north of West Dulwich, new teaching buildings and residences are typically built and refurbished around the academic year. When a college such as Capel Manor College, 1.2 miles south-east of West Dulwich, builds or refurbishes, the mastic package typically has to fit around students and staff.

When to call us in West Dulwich
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.
Common reasons buildings call us in:
- Bath and shower joints scraped during the final clean
- Internal caulk splitting as the building dries out
- Inconsistent sealant finishes from plot to plot
- Frame gaps too wide for sealant alone
For contractors refurbishing units at places like Hamilton Road Industrial Estate (less than half a mile south-west of West Dulwich), the mastic covers cladding panels, roller-door and window perimeters.
What to look for in a quote
- Their approach to joint depth and backing
- How the existing material will be dealt with
- What the guarantee covers, and for how long
- Whether primer will be used where the manufacturer specifies it
How the job changes by surface
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. The specification decides which, and colour-matched products can be used where the frame is on show.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Deciding which fire-stopping product a penetration needs
- Frames fitted out of tolerance
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.
Where we work in West Dulwich

Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in West Dulwich can be scarce. 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.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site
- Send asbestos survey details if the building is pre-2000

Advice
Site staff or a sealant 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 easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
