About our construction mastic in Catslip
We work to the specification and the programme. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. Site teams most often ask us about snag items on joints that need redoing before handover and old sealant on a refurbishment that needs stripping before new work, on window and door perimeters, internal decorators’ caulk and cladding and panel joints. Facilities teams, main contractors and managing agents in Catslip tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Catslip is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Quoting for work in Catslip
Each job is priced on its own details. The main factors are:
- How accessible the joints are

- How much existing material needs removing
A quote for mastic packages depends on quantities, condition and access, and any specification that applies. Call for a quote.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Anything awkward about access or site hours
- The site address and postcode
- Specification clauses that apply
- The type of building and who uses it
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call 01277 525 020 or send details through our quote form.
Construction mastic in Catslip: the local picture
Central London is about 38 miles from Catslip. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Catslip is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
Older buildings in the area around Catslip, such as Greys Court, which lies south-east of Catslip, need care when sealed: the product has to suit soft or historic materials. For contractors at a school such as Nettlebed Community School, sealing has to be finished before term starts.
Catslip is about 7 miles north of Caversham, in Oxfordshire. We cover commercial sites throughout Catslip, for single jobs and planned programmes alike. 423 places across Oxfordshire fall within our area, Catslip among them. We also cover Reading, some 9 miles away.

Different surfaces, different methods
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room, cutting out damaged joints and resealing them properly.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
Do you need construction mastic in Catslip?
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
Typical triggers for a call:
- Cracks opening in caulked internal joints
- External joints sealed in damp or cold conditions that are now failing
- Frame gaps too wide for sealant alone
- Sealant knocked or painted over by other trades
When units on a site such as Vanalloys Business Park, 2.3 miles to the south-west of Catslip, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Questions to ask before you book
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
- Their public liability cover
- The named product and why it was chosen
What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joint design decisions that belong to the architect or engineer
If in doubt, ring 01277 525 020 or use the quote form and we will say what we think.
What we seal
- Sanitary and kitchen joints

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep finished joints away from paint, plaster and scrapers
- Keep product details for future maintenance
- Bring the mastic contractor in after the last trades are through
- Put any product change through the designer first
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover, priced as part of the package or separately.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks.
Your questions answered
Can you keep pace with our programme in Catslip?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Catslip too far out for you?
No. Places such as Catslip are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you fit around our programme?
We follow the trades through the building. Areas are sealed as they’re released by the site team and we tell you if something stops an area being sealed.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Do you guarantee new-build sealant work?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we have finished isn’t covered.
