About our mastic sealing in Cliddesden
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. The enquiries we see most involve water getting in round frames after rain and complaints coming in block by block, on communal kitchens and washrooms, shopfronts below residential blocks and balcony and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Cliddesden it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For owners with a single building near Cliddesden, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Check sealant joints during planned building inspections
- Share the asbestos register when you send details
- List the paperwork your organisation requires when you send details
- Make it easy for occupiers to report draughts
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
Signs you need mastic sealing in Cliddesden
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
If one of these sounds familiar, it’s time for a closer look:
- Water getting in round frames after rain
- Window mastic that has split and shrunk
- Complaints coming in block by block
- Old repairs sealed over failed mastic
Schools and community buildings such as Cliddesden Primary School need frame and external mastic kept sound like any building.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
- Their plan for phasing and protecting the area

Cost factors for mastic joints
Each job is priced on its own details. The things that drive the figure:
- Joint width, depth and condition
- How much there is to seal
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Looking after buildings in and around Cliddesden
Cliddesden is about 47 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Rainfall across the South East, Cliddesden included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
For owners of several units at places like Viables Business Park (0.6 miles north of Cliddesden), one programme can deal with frame and external mastic across the lot. If you are responsible for a building such as Church of St Leonard, frame and door mastic needs the same attention as any other property.
