Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
What happens if it’s left?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Older rural buildings around Derringstone move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Construction mastic for commercial buildings in Derringstone
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve external joints sealed in damp or cold conditions that are now failing and inconsistent sealant finishes from plot to plot, across window and door perimeters, cladding and panel joints and internal decorators’ caulk. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Derringstone it comes down to the same thing: the right product in a properly prepared joint.
Construction in and around smaller places such as Derringstone 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.

FAQs: Derringstone
Is Derringstone too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on a hospital site such as Kent and Canterbury Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Can you fit around our programme?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Derringstone lies roughly 58 miles out from central London. 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.
Hotel extensions and refits, at places such as Broome Park Hotel (1.1 miles south-east of Derringstone), normally run between busy periods, so the sealing is squeezed into short windows.

When units on a site such as Barham Business Park (to the south-west of Derringstone) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

How the job changes by surface
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we’ve sealed
- Specifying the product where the designer hasn’t
If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think.
What we seal
- Sanitary and kitchen joints
- Floor and skirting junctions

Advice
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
After the work
For the best life from the joints:
- Share drawings and the specification as soon as possible
- Plan external elevations with the weather in mind
- Bring the mastic contractor in after the last trades are through
- 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, priced as part of the package or separately.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That normally means redoing finishes in a completed area and possibly a delayed handover. A check of every frame before decorators start is worth the time.
