Different surfaces, different methods
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. How each joint is reached is agreed at quote stage.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Mastic sealing in Stone Cross
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you have leaks at window and door perimeters and draughts at frames across a block, we can help, on window and door perimeters on blocks, communal kitchens and washrooms and shopfronts below residential blocks alike. Searching for sealant specialists in Stone Cross? We’ve been sealing commercial buildings since 2005.
In and around smaller places like Stone Cross, 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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact.

- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.

Advice
What we are called out for in Stone Cross
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one it comes away from one face.
If one of these sounds familiar, it’s time for a closer look:
- Estate-wide sealant that is simply worn out
- Communal area joints that look neglected
- Failed external movement joints
- Old repairs sealed over failed mastic
If you own or manage units on a site such as Speldhurst Business Park, 2.2 miles north-east of Stone Cross, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
What your quote should include
- Their pre-qualification and accreditations
- How the existing material will be dealt with
- Who will actually carry out the work
- What site paperwork they can supply
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Masonry that has broken away beside the joint
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Mastic sealing around Stone Cross: how the place shapes the job
Central London is about 28 miles from Stone Cross. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Stone Cross included, is lower than in many parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first.
Buildings close to stations like Ashurst Kent station (1 mile west of Stone Cross) are often flats over shops, with frame mastic to keep sound. Student accommodation around universities such as Canterbury Christ Church University - Salomons (to the north-east of Stone Cross) is normally managed block by block, which suits a planned mastic programme.

Your questions answered
Is a smaller place like Stone Cross outside your area?
Not at all. Stone Cross is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for a block close to Ashurst Kent station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Do you do block-wide mastic programmes?
We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Have the asbestos survey to hand for older buildings
- Keep a record of when each building was resealed
- Prioritise elevations facing the weather
- Plan resealing building by building rather than complaint by complaint
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
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.
