About our construction mastic in South Ruislip
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; any alternative we suggest is put to you before anything changes. Backing, primer and depth follow what the sealant maker sets out. Most enquiries involve bath and shower joints scraped during the final clean and early adhesion failures on new external joints, on brick and block movement joints, internal decorators’ caulk and sanitary and kitchen joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Ruislip is the same: the right product in a properly prepared joint.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What we are called out for in South Ruislip
Frames installed with uneven gaps make perimeter sealing harder. 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.
Things that usually lead to an enquiry:
- A mastic package split between trades with no clear owner
- Frame gaps too wide for sealant alone
- Window and door perimeters that won’t pass inspection
- A long mastic snag list close to completion
When units on a site such as Brook Retail Park, under half a mile to the south-east of South Ruislip, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
- The named product and why it was chosen
- What site paperwork they can supply

Different surfaces, different methods
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
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, with backing rod in deeper gaps.

Yes. Estates, retail parks and business parks around South Ruislip, Brook Retail Park among them, are all within reach. Photos and a short description are enough for a first look.
Can you work to our specification?
The specification decides the product. Product standards such as BS EN 15651 are often named in specifications.
Will you come and look before quoting?

It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
When a school such as Deanesfield Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Projects at colleges like Christ the Redeemer College, 1.7 miles to the north-east of South Ruislip, tend to run to term dates, so the mastic is planned tightly.

Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
