Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Check that water runs out of the downpipes
- Watch for drips in a downpour
- Watch the wall under the gutters for staining
- Don’t leave a sagging gutter
Clear the gutters once or twice a year so water doesn’t sit on the joints. Standing water strains every seal.
Early sealing limits how much water hits the wall. We will let you know if the gutter needs more than sealant.
Gutter sealing in Stanwell
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 old gutter sealant that has let go and open joints in fascias and soffits, on roofline trims, uPVC fascias and garage door frames.
Homes around Stanwell range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Every job is covered by a one-year guarantee, wherever you are in Surrey.

What the job involves on each surface
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.
Signs you need gutter sealing in Stanwell
End caps get knocked or pushed by water. If the seal fails, water escapes at the end.
Signs it’s time to call us include:
- Water running down the wall below the gutter
- Dripping gutter ends

- Earlier gutter repairs that have peeled off

FAQs for Stanwell
Is Stanwell within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Ashford Surrey station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Is gutter cleaning part of the job?
We clean the joints we are sealing and clear debris we find nearby. Cleaning the whole run is a different job.
Is sealant enough for a gutter that has dropped?
Not for long. The movement opens the joint again, so the fall and brackets need sorting first.
Can you fit new guttering?
Replacement isn’t our trade. We’ll tell you if the gutter needs replacing so you can call the right trade.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Quotes for gutter sealing in Stanwell

DIY sealant or a professional job?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Stanwell buildings and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Stanwell Fields CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Leave it or put it right?
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right before the damage spreads. Around Stanwell, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
