How we handle construction mastic in Fawkham Green
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers on schemes in Fawkham Green. If you have sealant knocked or painted over by other trades and different trades sealing to different standards, we can help, whatever the surface. Most enquiries from Fawkham Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Construction in and around smaller places such as Fawkham Green 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common questions from Fawkham Green clients
Is Fawkham Green off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you take on a job at a hospital such as Darent Valley Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Do you do internal caulk as well as external mastic?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. We price to the specification and drawings.
Do your applicators hold CSCS cards?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
Doing it in-house
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. If others near Fawkham Green need work, visits can be combined. A fixed quote is given before anything starts.

New build and refits around Fawkham Green
Central London is about 19 miles from Fawkham Green. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. The South East is one of the drier 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.
When units on a site such as Heaver Farm Trading Estate (0.7 miles south-east of Fawkham Green) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For a contractor at a hotel such as Brands Hatch Hotel, which lies south-west of Fawkham Green, the mastic often has to be finished before a reopening date. New wings at hospitals like Darent Valley Hospital (4.9 miles north of Fawkham Green) bring long runs of window and panel joints to seal.

Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Oversized gaps that need packing or adjustment by others
- Faulty frames rather than failed sealant
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer.
Surfaces we seal

Details that help us quote
We can often quote from photographs and a few details. Please tell us:
- Whether an asbestos survey exists
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
To get a fixed quote, phone 01277 525 020 or use the quote form with the site address and an outline of the work. Our quote form is another easy route.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Plan external elevations with the weather in mind
- Check frame gaps are within the sealant’s range before sealing
- Ask for joint and product checks before the package is urgent
- Protect sealed areas from following trades
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit as agreed in the quote.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
