What happens if it’s left?
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. Where a wall is exposed, as many are in small places like Knatts Valley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Knatts Valley questions
I let a flat near Kemsing station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Knatts Valley?
Yes, Knatts Valley is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will sealing fix a sagging gutter?
Not for long. The movement opens the joint again, so the fall and brackets need sorting first.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How long will you be here?
Most jobs take a few hours, depending on the number of joints and the access, including preparation and clearing up. We will confirm how long when we quote.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
How do I get a quote for gutter sealing in Knatts Valley?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
What the job involves on each surface
Garage door frames
A fresh seal around the frame stops rain getting in.
uPVC fascias
Our work is the joints, not new fascias. If boards are damaged, we’ll tell you.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep an eye out for wet patches below a joint
- Get a dropping gutter looked at quickly
- Sort out a dripping joint early
- Check that water runs out of the downpipes
Give the sealant the cure time we tell you and avoid disturbing it.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.

Related advice
Landlords, agents and businesses in Knatts Valley
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Walls and rooflines in Knatts Valley
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Lullingstone Castle (about 2.8 miles north-west) nearby, there’s older building stock in the area around Knatts Valley as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Kemsing station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you look after a building such as West Kingsdown CofE VC Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of Saint Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move.
