Common questions in Westerham
Do you cover Westerham for gutter sealing?
Yes, Westerham is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Is parking a problem for a job in Westerham?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Is the work guaranteed?
There’s a 12-month guarantee on every job, gutter and fascia work included.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Do you clean gutters?
The joints we seal are cleaned out and clear debris we find nearby. A full gutter clean is a separate service.
Can I choose the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
How do I get a quote for gutter sealing in Westerham?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Gutter sealing for homes and businesses in Westerham
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. Typical jobs include trim joints where the sealant has failed and quick sealant fixes on gutters that didn’t last, on gutter end caps, roofline trims and soffit joints.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.
Our work is backed for twelve months.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What happens if it’s left?
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Westerham.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- A choice of colours where the product allows
- A 12-month guarantee on all work
- Sealant colour chosen to suit
- An ARBOMaster approved applicator

Walls and rooflines in Westerham
Historic houses like Quebec House (about 0.2 miles south-east) are a reminder that the area around Westerham has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Westerham can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Hurst Green station, leaking gutter joints on a rental are best caught before they stain the walls.

Advice
What affects the quote in Westerham
The quote reflects the job in front of us. We look at:
- The type of sealant required
- Whether there’s mould to deal with
- The number and length of the joints
- The old material and how stubborn it is
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- The rough size of the job
- Whether it’s a home or a business
- Any access issues, like height or stairs
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.
Common problems we fix in Westerham
End caps get knocked or pushed by water. If the seal fails, water escapes at the end.
Look out for these signs:
- Old gutter sealant that has let go
- Rain getting in around a garage door
- Dripping gutter ends
- Drips from gutter joints and end caps
If you live in an older home near Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- How the joint is cleaned and prepared
- Which colour the sealant will be
- Whether they’re fully insured
- Who does the work, and how experienced they are
