About our mastic sealing in Chainhurst
Across Chainhurst and the rest of Kent, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you’re dealing with draughts at frames across a block and old repairs sealed over failed mastic, we can put it right, whatever the surface. For commercial sealant work in Chainhurst, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions near places like Chainhurst often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What the job involves on each surface
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler and easier to manage.
What else we do in Chainhurst
Why act early in Chainhurst
Draughts round window perimeters cost occupiers comfort and the windows normally get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Around Chainhurst, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
A quote for mastic joints depends on how many there are, their condition and the access. Call for a quote.

Questions we are asked in Chainhurst
Is Chainhurst off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
We manage a building near Marden station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How many days will you need on site?
It depends on the scope, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Commercial clients in Chainhurst
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
Frames, entrances and external joints in Chainhurst
Chainhurst lies roughly 32 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Chainhurst is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
For owners of several units at places like Woodfalls Industrial Estate, 2.7 miles west of Chainhurst, one programme can deal with frame and external mastic across the lot. Buildings close to stations like Marden station (2 miles south of Chainhurst) are often flats over shops, with frame mastic to keep sound. Student accommodation around universities such as University for the Creative Arts - Maidstone, 4.8 miles to the north of Chainhurst, is usually managed block by block, which suits a planned mastic programme.

What sets the cost
We price every job individually. The main factors are:
- Joint width, depth and condition
- Distance, for remote addresses
- Working within restricted access windows
- The product specified
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- Access details, including height
- Specification clauses that apply
- A wide shot and a close-up of the area
- When you need the work done
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or send details through our quote form.
Site staff or a sealant specialist?
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.
Putting right a botched joint often costs more than sealing it well at the start, 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.
