Mastic sealing in Knave's Ash, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Site teams most often ask us about the same joint failures repeated across a portfolio and communal area joints that look neglected, across communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Knave's Ash it comes down to the same thing: the right product in a properly prepared joint.
Rural conversions near places like Knave's Ash 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.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

What else we do in Knave's Ash
Looking after buildings in and around Knave's Ash
Knave's Ash is within about 3 miles of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do; plan inspections around that. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Churches, halls and community buildings such as Church of the Holy Cross are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Student blocks close to universities like University of Kent (4.8 miles south-west of Knave's Ash) are easiest to work on between tenancies. Landlords with units on estates such as Chislet Business Park, 1 mile to the south-east of Knave's Ash, can bring frame, door and external mastic across several units into one programme.
Knave's Ash is about 2 miles south of Herne Bay, in Kent. We cover commercial sites throughout Knave's Ash, for single jobs and planned programmes alike. Across Kent, 931 places are covered, Knave's Ash among them. Sites around London have their own page, about 55 miles away.

Quoting for work in Knave's Ash
Before we quote, we look at:
- How much there is to seal
- The product specified
- Whether the work must be split into stages
- Access and working height
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Sending details for a quote
However big the job, the same details help:
- Any dates the work must fit around
- How the joints are reached, and at what height
- The product your specification calls for
- The site address and postcode
Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or email drawings and photos.
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Look at the sunniest and most exposed elevations first
- Avoid piecemeal callouts where you can
- Share the asbestos register when you send details
- Protect low-level joints in entrances
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
Your questions answered
Our building in Knave's Ash is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is Knave's Ash off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
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 inspection is the best way to catch problems early.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Water coming in from the roof or rainwater goods
- Glazing that needs replacing
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Balcony and threshold joints
- External wall and movement joints
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
How the job changes by surface
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
