Photos, a specification or a quick description of the joints is enough to start a fixed quote.
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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Around places like Caversham Heights, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.
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.

Looking after the joints
After handover, these steps help:
- Put any product change through the designer first
- Ask installers to correct oversized gaps first
- 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. We can return to clear snags before handover as agreed in the quote.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.

When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Damage to finishes by other trades after we have sealed
- Frame gaps too wide for sealant, which the installer needs to correct
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think.
Joints and surfaces we work on

Do you need construction mastic in Caversham Heights?
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
If one of these sounds familiar, it’s time for a closer look:
- Mastic snags holding up handover
- Early adhesion failures on new external joints
- Sanitary sealant damaged by following trades
- Window and door perimeters that won’t pass inspection
When units on a site such as The Station Shopping Park, 1.2 miles to the south-east of Caversham Heights, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

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.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. Joints are sealed smooth so they’re easy to clean.
Contractors’ notes for Caversham Heights
Rainfall across the South East, Caversham Heights included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 39 miles from central London, Caversham Heights is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Extensions at sites like Spire Dunedin Hospital, 1.8 miles to the south of Caversham Heights, typically sit beside working departments, and the mastic follows strict access rules.

Common questions from Caversham Heights clients
Is hospital work, at somewhere like Spire Dunedin Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Could you schedule work at a campus like University of Reading for the vacation?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Can you seal external joints in wet or cold weather?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems so it’s better to wait.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can fire-rated sealing at service penetrations be included?
We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. We’ll flag if the detail needs a different product.
