We can work into your cyclical maintenance plan, building by building.
About our mastic sealing in Shipbourne
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Shipbourne carry our 12-month guarantee. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and the failures we are asked to look at most are mastic failing across several blocks on an estate and cracked, hardened mastic round windows on a block. Whoever orders the work in Shipbourne, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Rural conversions near places like Shipbourne 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.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Questions about Shipbourne
Do you take on block-wide or estate-wide mastic work in Shipbourne?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
Is Shipbourne too small for you to travel to?
Not at all. Shipbourne is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.
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.
Honest limits
Honesty saves time and money. Fresh joints won’t solve:
- 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
- Glazing that needs replacing
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.

What else we do in Shipbourne
Mastic sealing in Shipbourne: the local picture
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first. At about 24 miles from central London, Shipbourne is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
If you manage student housing near a university such as University of Kent - Tonbridge, 3.8 miles to the south of Shipbourne, the summer turnaround is the time for mastic. Site managers at schools like Shipbourne School can fit frame mastic into the summer works.
Shipbourne is about 3 miles north of Tonbridge, in Kent. We send applicators to Shipbourne for mastic joints, handled exactly as we handle every other area. We work across 931 places in Kent, from busy centres to rural villages. Our London page has more on work in that area.
We cover the TN11 postcode districts. If your site is on Upper Green Road, Upper Green Lane and Back Lane or close by, send details and we will quote for mastic joints. We also cover Budds (1 mile west), Yopps Green (1 mile north), Sheet Hill (2 miles north), Ivy Hatch (2 miles north) and Coldharbour (2 miles south-west) for mastic joints.

When to call us in Shipbourne
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.
Most enquiries start with one or more of the following:
- Occupiers reporting cold air round windows
- Mastic failing across several blocks on an estate
- Brittle perimeter mastic across a building
- Damp patches beside frames
Older buildings near Shipbourne, from historic houses such as Ightham Mote, 1.1 miles to the north-west of Shipbourne, to more modest stock, need compatible products when frames are resealed.
Questions to ask before you book
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
- Their plan for phasing and protecting the area
- What site paperwork they can supply
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What happens if it’s left?
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. Around Shipbourne, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use.

- 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.
What we need from you
