How we handle gutter sealing in Warnham
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame with an exterior sealant. Typical jobs include internal damp traced to a gutter joint and old sealant on roofline trims that has split, on gutter joints, roofline trims and uPVC fascias.
Older homes in small places like Warnham may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Walls and rooflines in Warnham
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.
Homes close to The Parish Church of St Margaret include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Warnham CofE Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look at the gutters while it’s raining
- Don’t leave a sagging gutter
- Keep an eye out for wet patches below a joint
- Get leaks sealed before the wet months
Clear the gutters once or twice a year so water doesn’t sit on the joints. Standing water strains every seal.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.
When to call us in Warnham
Stop ends take pressure from water running along the gutter. Once the seal behind them fails, they drip.
People usually contact us when they notice something like this:
- Water running down the wall below the gutter
- Garage door frames letting rain in
- Water dripping where gutter sections meet
- Open joints in fascias and soffits
If you let a flat or house near Warnham station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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. In a small place like Warnham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Advice
Common questions in Warnham
Do you cover smaller places like Warnham?
Yes, Warnham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Warnham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you guarantee gutter sealing?
All our work carries a one-year guarantee, and we’re fully insured.
Is sealing fascia joints something you do?
Yes. We seal the joints, not replace the boards, and if a board is damaged, we will tell you.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Brackets that have snapped or loosened
- Fascias that need replacing
- Problems with the roof covering
If in doubt, call 0345 464 0079 or email us and we will say what we think.
