How we handle gutter sealing in Newtown
A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Sealing it is quick while the gutter is still sound. Common call-outs are for cracked sealant along roofline trims and leaking gutter joints and stop ends, on garage door frames, gutter joints and gutter end caps.
In a smaller place like Newtown, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That’s where gutter joints and wall joints tend to fail first.
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.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, 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.
Outside joints around Newtown
Historic houses like Godinton House (about 2.9 miles north-west) are a reminder that the area around Newtown 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as East Stour Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Christ Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Newtown
Is Newtown within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Ashford International station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How long will you be here?
Typically it takes an hour or two for a few joints, longer for a full run. Bigger jobs take longer, and we’ll say how long yours will take.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Is sealant enough for a gutter that has dropped?
It won’t last. The movement opens the joint again so the gutter has to be refixed first.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What we’re called out for in Newtown
Leaves and moss hold water in the gutter. Water that cannot drain works its way through a weak joint and leaks out.
Keep an eye out for any of the following:
- Failed sealant on a garage door frame
- Streaks down the brickwork from a leaking joint
- Cracked sealant along roofline trims
- Damp patches inside below a leaking gutter
Letting a property close to Ashford International station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

How the job changes by surface
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
Gutter joints
Gutter joints move and sit in water. A dedicated gutter sealant suits them.
What sealant work cannot fix
New sealant can’t fix everything, and we’ll tell you before any work starts. It will not solve:
- Leaks from the roof rather than a joint
- Blocked downpipes
- Gutters that have dropped or pulled away
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on

Why act early in Newtown
Replacing guttering is a much bigger job than sealing joints. Where the gutter is in good order and only a joint leaks, resealing is the sensible fix. If it’s broken or sagging, a gutter installer needs to look. Homes in smaller places like Newtown can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Make sure downpipes aren’t blocked
- Keep ladders off the guttering
- Look for streaks or damp on the wall below gutters
- Get leaks sealed before the wet months
Give the sealant the cure time we tell you before poking or cleaning near it.
Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the number of joints and the access and we leave things clean and tidy. For a job in Newtown, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
