Construction mastic in Knockholt Pound, done properly
Mastic Doctor has been a subcontractor on construction projects for over 20 years. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades.

Conversions of older rural buildings near smaller places such as Knockholt Pound bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What the job involves on each surface
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately, depending on what suits the programme.
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product and hygienic or food-safe grades wherever food contact is possible.
Should maintenance staff do it?
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.
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. Getting these wrong usually costs more in the end than doing them right.
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep finished joints away from paint, plaster and scrapers
- Flag uneven or tapered frame gaps early
- Get the mastic subcontractor involved early in the programme
- Plan external elevations with the weather in mind
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out and keeps handover on track.
Questions about Knockholt Pound
Can you work on a hospital site such as Chelsfield Park Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Does your area include sites such as North Downs Business Park, near Knockholt Pound?
Yes. We cover Knockholt Pound and the area around it, including industrial estates, business parks and retail parks such as North Downs Business Park. A few photos and the unit address let us price the work.
Do you cover Knockholt Pound?
Yes. Sites across Knockholt Pound are covered.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

What else we do in Knockholt Pound
Why deal with it now?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. If the frame is life-expired, we’ll tell you. Older rural buildings around Knockholt Pound 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.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Knockholt Pound is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
