About our construction mastic in Northbourne
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we’re fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. The enquiries we see most involve snag items on joints that need redoing before handover and caulk cracking where joints are moving more than expected, across internal decorators’ caulk, floor and skirting junctions and cladding and panel joints. Whoever orders the work in Northbourne, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Northbourne bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Signs you need construction mastic in Northbourne
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
These are often picked up first by site or facilities staff:
- Inconsistent sealant finishes from plot to plot
- Sealant knocked or painted over by other trades
- Window and door perimeters that won’t pass inspection
- Cracks opening in caulked internal joints
When units on a site such as Pike Road Industrial Estate, 3 miles west of Northbourne, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Questions to ask before you book
- Their approach to joint depth and backing
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area
- Proof of insurance
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frames fitted out of tolerance
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Joints and surfaces we work on
- Sanitary and kitchen joints
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
- Internal decorators’ caulk
- Brick and block movement joints
What happens if it’s left?
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Northbourne, rather than one at a time. Photos of every joint help us quote for the whole job.
A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Advice
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep product details for future maintenance
- Flag uneven or tapered frame gaps early
- Share drawings and the specification as soon as possible
- Keep finished joints away from paint, plaster and scrapers
A new structure shifts as it loses construction moisture. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. If that happens, let us know.
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.
Your questions answered
Is hospital work, at somewhere like Victoria Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Northbourne off your patch?
Not at all. Northbourne is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can staff carry on working while you are here?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Can you work to our specification?
We follow the specified sealant. Specifications often reference BS EN 15651 or BS 6213.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Construction mastic around Northbourne: points for this area
At about 65 miles from central London, Northbourne is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Rainfall across the South East, Northbourne 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.
School extensions, at buildings such as Northbourne Church of England Primary School, normally run to the summer holidays, mastic included. For a contractor working at a hospital such as Victoria Hospital, 2.2 miles to the east of Northbourne, perimeter and facade sealing is planned around patients and deliveries.
