About our construction mastic in Upstreet
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers with projects in Upstreet. If you’re dealing with existing joints on a refurb that need cutting out and resealing and sanitary sealant damaged by following trades, we can put it right, on sanitary and kitchen joints, internal decorators’ caulk and floor and skirting junctions alike. For commercial sealant work in Upstreet, you deal with one contact from quote to sign-off, whether it’s one building or several.
In the countryside around places like Upstreet, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Your questions answered
Is a hospital such as St Martins Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you cover business parks and estates near Upstreet, such as Canterbury Industrial Park?
Yes. Estates, retail parks and business parks around Upstreet, Canterbury Industrial Park among them, are all within reach. A few photographs and the unit address let us price the work.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we’ll set out a timescale with the quote.
What happens if old sealant might contain asbestos?
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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

What else we do in Upstreet
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a day or two on a small fit-out and several weeks on a large multi-storey package, and our waste is bagged and taken away as we go. For work around Upstreet, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- Point out any areas we must not close
- Explain the parking and delivery arrangements

Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites around Upstreet. Several sites can go on one quote, so there’s one set of paperwork to deal with.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
What happens if it’s left?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility, with the same standard on every plot. One visit to deal with every failing joint makes more sense than several trips to a place like Upstreet. Photos of every joint help us quote for the whole job.
A quote for mastic packages depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
- Deciding which fire-stopping product a penetration needs
If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

- Floor and skirting junctions
- Internal decorators’ caulk
- Cladding and panel joints
- Sanitary and kitchen joints
- Window and door perimeters
- Brick and block movement joints
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Check frame gaps are within the sealant’s range before sealing
- Ask cleaners to use soft cloths around fresh sealant
- Record the products used in the O&M file
- Ask for joint and product checks before the package is urgent
Record which products went where in the handover file. Future maintenance is easier when the products are known. Tell us what records you need and we will confirm with the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.
Construction mastic in Upstreet: the local picture
Rainfall across the South East, Upstreet included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. At about 57 miles from central London, Upstreet is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
New wings at hospitals like St Martins Hospital, 5.2 miles south-west of Upstreet, bring long runs of window and panel joints to seal. Projects at schools like Chislet Church of England Primary School work to term dates, so mastic is programmed tightly. Recladding or extending a unit at a site like Canterbury Industrial Park (1.3 miles south-west of Upstreet) brings panel joints and frame perimeters into the programme.
