FAQs: Windmill Hill
Will you take on a block within reach of Gravesend station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Can you work at a site such as Canal Industrial Park, by Windmill Hill?
Yes. Our area takes in Windmill Hill and its surroundings, with estates and business parks such as Canal Industrial Park included. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
About our mastic sealing in Windmill Hill
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. Most enquiries involve leaks at window and door perimeters and window mastic that has split and shrunk, on balcony and threshold joints, window and door perimeters on blocks and communal kitchens and washrooms. Most enquiries from Windmill Hill 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 a smaller place such as Windmill Hill, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Why act early in Windmill Hill
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Small buildings around Windmill Hill suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Trustees of buildings like Christ Church Milton can bring frame and external mastic into a planned maintenance list. If you manage student housing near a university such as University of Greenwich (4.5 miles west of Windmill Hill), the summer turnaround is the time for mastic.

Owners, agents and contractors
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Windmill Hill. Several sites can go on one quote, which keeps the paperwork simple.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- List the paperwork your organisation requires when you send details
- Keep bins and bikes away from communal door frames
- Check the asbestos register before any old mastic is disturbed
- Keep a record of when each building was resealed
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.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Water coming in from the roof or rainwater goods
- Frames that are rotten, warped or broken
- Asbestos-containing sealant, which we don’t remove
If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.
What we seal
- Balcony and threshold joints
- External wall and movement joints
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Window and door perimeters on blocks
When to call us in Windmill Hill
The edges of the material itself sometimes break away for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
These are often picked up first by site or facilities staff:
- Repeated reactive repairs to the same buildings
- Brittle perimeter mastic across a building
- Open joints in brickwork or panels
- Worn sealant at communal door frames
For owners of several units at places like Canal Industrial Park, which lies north-east of Windmill Hill, one programme can deal with frame and external mastic across the lot.
