Mastic sealing across Whitehill
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What we’re called out for in Whitehill
Buildings move with temperature and moisture, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Things that typically lead to an enquiry:
- Occupiers reporting cold air round windows
- Damaged joints in communal entrances and corridors
- Repeated reactive repairs to the same buildings
- Brittle perimeter mastic across a building
Trustees of buildings like Church of St Peter and St Paul can bring frame and external mastic into a planned maintenance list.
What to look for in a quote
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
- How they handle RAMS and site documents
- What the guarantee covers, and for how long
Mastic sealing in Whitehill, 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. We work on external wall and movement joints, communal kitchens and washrooms and window and door perimeters on blocks, and the failures we’re asked to look at most are the same joint failures repeated across a portfolio and damp patches beside frames. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Whitehill is the same: the right product in a properly prepared joint.
In and around smaller places like Whitehill, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Honest limits
Some faults sit outside our scope, and we say so rather than covering them up:
- Frames that are rotten, warped or broken
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly.

What else we do in Whitehill
Block-wide mastic in Whitehill
At about 44 miles from central London, Whitehill is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Historic properties like Belmont House and Gardens, 2.4 miles south-west of Whitehill, show the age of some local stock, where frame mastic must suit soft brick or stone. Site managers at schools like Ospringe Church of England Primary School can fit frame mastic into the summer works.
Whitehill is about 1 mile south-west of Faversham, in Kent. We cover Whitehill and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, about 44 miles away.

Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients 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.
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Leave it or put it right?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure and less choice about when. Around Whitehill, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Access can matter as much as the joints themselves: 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.

Advice
FAQs: Whitehill
Can one quote cover a number of our buildings near Whitehill?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Is Whitehill too small for you to travel to?
Not at all. Whitehill is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How do you handle work on occupied blocks?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Surface by surface
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. How each joint is reached is agreed at quote stage.
