Gutter sealing in Cowley, done properly
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where one is available. If you’re dealing with old sealant on roofline trims that has split and internal damp traced to a gutter joint, we can put it right, whatever the surface.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. For a flat in Cowley, check the lease for who looks after the outside.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Common questions in Cowley
I let a flat near West Drayton station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Is parking a problem for a job in Cowley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
How long does gutter sealing take?
A typical job takes a few hours, depending on the number of joints and the access. Your quote will say how long we expect yours to take.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do you seal gaps in fascias and soffits?
Yes. We seal open joints along fascias and soffits in a colour to suit.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.

What else we do in Cowley
What happens if it’s left?
You don’t need to replace a garage door because rain gets in round the frame. Sealing the frame normally stops it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Cowley, the repair is bigger than a sealant job.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Do you need gutter sealing in Cowley?
Sagging sections pull joints apart. Resealing a sagging joint won’t last so the brackets need attention first.
The most common problems we see are:
- Trim joints where the sealant has failed
- Damp patches inside below a leaking gutter
- Quick sealant fixes on gutters that didn’t last
- Water running down the wall below the gutter
Rented homes near West Drayton station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

What gutter sealing looks like in Cowley
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. Historic houses like Ickenham Hall (about 2.9 miles north-east) are a reminder that the area around Cowley has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Cowley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. In the older streets around Church of St Laurence, older walls, gutters and the joints where extensions meet them need a flexible sealant.
