Walls and rooflines in Bidborough
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Penshurst Place (about 2.3 miles west) are a reminder that the area around Bidborough has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Parish Church of St Lawrence, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Leigh (Kent) station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

External mastic for homes and businesses in Bidborough
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you are dealing with failed seals between different materials and panel joints letting water in, we can help.
Older homes in small places like Bidborough may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
Each job carries a 12-month guarantee.

Why act early in Bidborough
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a small place like Bidborough, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Bidborough, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Mention any tricky access

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Check external joints each spring
- Leave the joints unpainted unless we have said otherwise
- Do not let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
FAQs for Bidborough
Can you help a landlord with a rental near Leigh (Kent) station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Is Bidborough within the area you cover?
Yes. Bidborough is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How do I get a quote for external mastic in Bidborough?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us and tell us what needs doing and where.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Signs you need external mastic in Bidborough
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
The problems people usually mention when they call are:
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
- Joints pointed up with cement by mistake
Managing a site like Southborough CofE Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
