Chitty: questions and answers
Does the sea air around Chitty change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
We manage a building near Herne Bay station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Mastic sealing in Chitty
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. The enquiries we see most involve the same joint failures repeated across a portfolio and water getting in round frames after rain, on communal kitchens and washrooms, external wall and movement joints and window and door perimeters on blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Chitty it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions near places like Chitty 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after buildings in and around Chitty
Chitty sits close to the coast, within about 3 miles. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Chitty lies roughly 57 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
If you’re responsible for a building such as Church of St Mary the Virgin, frame and door mastic needs the same attention as any other property. For a school such as Chislet Church of England Primary School, perimeter mastic on windows and doors is a holiday job.
Chitty is about 4 miles south-east of Herne Bay, in Kent. Across the CT3 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 931 places across Kent fall within our area, including Chitty. For work in that direction, see our London page (57 miles or so).
Work on mastic joints is covered throughout CT3, for business premises of every kind. We also cover Chislet (1 mile west), Hollow Street (1 mile south-west), Boyden Gate (1 mile north-west), Old Tree (1 mile west) and Highstead (1 mile north-west). Bigger towns within reach include Canterbury (7 miles south-west), Margate (9 miles east), Dover (14 miles south), Ramsgate (9 miles east), Broadstairs (10 miles east) and Whitstable (7 miles west).

Work for main contractors and building owners
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Chitty can form part of a wider programme across Kent.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Signs you need mastic sealing in Chitty
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Common reasons buildings call us in:
- Complaints coming in block by block
- Worn sealant at communal door frames
- Window mastic that has split and shrunk
- Old repairs sealed over failed mastic
For agents with blocks near Herne Bay station (4 miles north-west of Chitty), a block-wide mastic programme deals with frames, balconies and entrances in one go.
What your quote should include
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
- Are they CHAS accredited or on Constructionline?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
What happens if it’s left?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Around Chitty, 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.
Why us?
- Standard and matched colours in many product ranges
- Colours chosen to suit frames, cladding or finishes where possible
- Commercial sealant work since 2005
- Workmanship guaranteed for 12 months

What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Failed window or door frames, which need a window contractor
- Materials that need asbestos testing before work
- Masonry that has broken away beside the joint
If you are not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Surfaces we seal
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Share the asbestos register when you send details
- Avoid piecemeal callouts where you can
- Log resealing dates block by block
- Mention RAMS, insurance or CSCS requirements up front
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a few days for most blocks, with larger programmes scheduled building by building. For a building around Chitty, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected
- Point out any areas we must not close
