Construction mastic in Lashenden
On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers, sealing plot by plot or floor by floor as areas are released. We work on sanitary and kitchen joints, cladding and panel joints and floor and skirting junctions, and what we’re called in for most is external joints sealed in damp or cold conditions that are now failing and oversized or tapered gaps around new frames. A specialist sealant contractor works differently from a general builder: in Lashenden, that means joint design, primers and backing rod as standard.
Conversions of older rural buildings near smaller places such as Lashenden 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 normally what’s needed.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Lashenden are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close

Advice
General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lashenden can sit alongside others in a wider programme across Kent.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Common problems we fix in Lashenden
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Site and facilities staff are often the first to spot these:
- A mastic package split between trades with no clear owner
- Window and door perimeters that won’t pass inspection
- Internal caulk splitting as the building dries out
- External joints sealed in damp or cold conditions that are now failing
Extensions at sites like Benenden Hospital, 3.9 miles to the south of Lashenden, usually sit beside working departments, and the mastic follows strict access rules.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- Their public liability cover
- How long is the guarantee, and what does it include?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Put any product change through the designer first
- Ask for joint and product checks before the package is urgent
- Record the products used in the O&M file
- Keep finished joints away from paint, plaster and scrapers
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.
Mastic packages on Lashenden sites
Lashenden lies roughly 40 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Lashenden included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.
Sites around Lashenden get mastic sealed to the drawings and the programme, nothing improvised.

Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. Where an alternative is genuinely suitable, we will say so. Around Lashenden, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Lashenden: questions and answers
Can you work to our programme on a site in or near Lashenden?
Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is hospital work, at somewhere like Benenden Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Can you fit around our programme?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
