Challock: questions and answers
Is Challock too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you work for managing agents with blocks near Wye station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
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.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
How we handle mastic sealing in Challock
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and leaks at window and door perimeters. Most enquiries from Challock start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Challock, 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 sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Blocks and managed buildings in Challock
The South East is one of the drier parts of the UK. 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. Challock is about 46 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
For a school such as Challock Primary School, perimeter mastic on windows and doors is a holiday job. For agents with blocks near Wye station, which lies south-east of Challock, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Challock is about 5 miles north of Ashford, in Kent. We cover commercial sites throughout Challock. Our Kent coverage takes in 931 places, large and small. For work in that direction, see our London page.
Commercial sites across TN25 are covered for mastic joints. Among the streets we cover are Chapmans Close, Blind Lane and Old Clock House Green, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Pested (1 mile north), Paddock (1 mile west), Stocker's Head (3 miles west), Badlesmere (3 miles north) and Throwley Forstal (3 miles north). Nearby towns on our patch include Maidstone (15 miles west), Ashford (5 miles south), Canterbury (10 miles north-east), Sittingbourne (11 miles north-west), Whitstable (11 miles north-east) and Faversham (7 miles north).
Near you in Challock
Around Challock, our work takes us to commercial buildings near The Chequers pub and The Hayesbrook School. The closest station to Challock is Wye station, about 3.3 miles south-east of the centre. A little further out are Tower keep castle at Chilham (3.9 miles north-east) and William Harvey Hospital (5.6 miles south).
What happens if it’s left?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Around Challock, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.
Why appoint us
- CHAS accredited contractor
- Old sealant cut out, never sealed over
- Products installed to the manufacturer’s instructions
- Fully insured
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.
What we seal
- Balcony and threshold joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
What we are called out for in Challock
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
Any of the following is a good reason to get the joints checked over:
- Occupiers reporting cold air round windows
- Movement joints with sealant missing
- Old repairs sealed over failed mastic
- No planned programme for sealant
Trustees of buildings like Church of St Cosmas and St Damian can bring frame and external mastic into a planned maintenance list.
Comparing quotes
- Can the work be phased to keep areas open?
- Who will actually carry out the work
- Health and safety accreditation such as CHAS
- Their approach to joint depth and backing
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For work around Challock, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Preparing the site
- Share your working hours and any access restrictions
- Move anything stored against the joints
- Warn occupants and staff about the work

How the job changes by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
Maintenance after handover
To get the most from the new sealant:
- Group repairs into a planned programme
- Track which buildings were done and when
- Check sealant joints during planned building inspections
- List the paperwork your organisation requires when you send details
Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
