Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How we handle gutter sealing in Cowplain
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed with an exterior sealant. We work on roofline trims, uPVC fascias and soffit joints, and common reasons people get in touch are quick sealant fixes on gutters that didn’t last and damp patches inside below a leaking gutter.
In and around Cowplain, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Whatever the size of the job, you get the same 12-month guarantee.

Common questions in Cowplain
Is Cowplain in your area for gutter sealing?
Yes. We work across London and the South East, and Cowplain is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Do you work for landlords with property near Rowlands Castle station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Can sealant stop a sagging gutter leaking?
No. A sagging gutter pulls its joints apart, so the brackets need fixing first.
Can you seal fascia and soffit joints?
Yes, often alongside gutter joints. Each joint is cleaned and sealed with a suitable exterior sealant.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
How the job changes by surface
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily with a matching sealant where possible.
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Rest ladders on the wall, not the gutter
- Get leaks sealed before the wet months
- Clean out the gutters once or twice a year
- Keep an eye out for wet patches below a joint
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
Outside joints around Cowplain
With historic houses such as Warblington Castle (about 4.5 miles south-east) nearby, there’s older building stock in the area around Cowplain as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Rowlands Castle station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Managing a site like Woodcroft Primary? Then its movement joints, gutters and trims need looking after like any other building’s.

What happens if it’s left?
Sealant will not clear a blocked downpipe. We look at what’s really happening and tell you if something else is needed. In an older home around Cowplain, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Do you need gutter sealing in Cowplain?
Gutter joints rely on seals that age. Temperature changes make gutters move and that movement opens up tired joints.
Most people get in touch after spotting one of these:
- Streaks down the brickwork from a leaking joint
- Rain getting in around a garage door
- Quick sealant fixes on gutters that didn’t last
- Internal damp traced to a gutter joint
Homes close to The Hart Plain Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
