What gutter sealing looks like in Northolt
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Willow Tree Primary School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to St Richard's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

About our gutter sealing in Northolt
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first, then dry the joint before sealing. We work on gutter joints, gutter end caps and roofline trims, and the jobs we see most are damp patches inside below a leaking gutter and old gutter sealant that has let go.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Northolt, tell us how high the joints are and how to reach the back of the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How it works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on the number of joints and the access for a typical job. In Northolt, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, we find the drip and check the gutter is not cracked or sagging.
- We clean out the joint and take out the old sealant.
- We make sure the joint is dry before sealing.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we are there.
Before we arrive
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

Your questions about gutter sealing in Northolt
Is parking a problem for a job in Northolt?
Parking in Northolt, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Northolt Park station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is the work guaranteed?
Our 12-month guarantee covers every job.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you fit new guttering?
No. We seal leaking joints and trims. Replacement needs a gutter installer or roofer.
Is it possible to stop a gutter joint dripping with sealant?
Often, yes. A clean, dry joint resealed with gutter sealant usually stops the drip. If the section is split or warped, it needs replacing.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Do you need gutter sealing in Northolt?
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.
If you can see any of these, it’s time to have the joints looked at:
- Old gutter sealant that has let go
- Wet patches on the wall under a gutter joint
- Damp patches inside below a leaking gutter
- Stop ends leaking at the end of a run
As a London address, Northolt can be tricky for parking: let us know about parking bays, permits or a driveway.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
