Gutter sealing for homes and businesses in Herne Hill
Failed sealant round a garage door frame lets rain blow in. The frame joint is cut out and resealed with an exterior sealant. We’re often asked to deal with end caps that drip every time it rains and gaps along fascia and soffit joints, on garage door frames, gutter end caps and soffit joints.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. For a flat in Herne Hill, check the lease for who looks after the outside.
Each job carries a 12-month guarantee, large or small.

Herne Hill questions
I let a flat near North Dulwich station. Can you help?
Yes. We work for landlords and agents as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Is Herne Hill in your area for gutter sealing?
Yes, Herne Hill is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Can you seal fascia and soffit joints?
Yes. Open joints along uPVC fascias and soffits can be sealed in a matching colour.
Will sealant fix a dripping gutter joint?
Most of the time. A sagging or cracked gutter needs more than sealant, and we will tell you.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Why it’s worth doing now in Herne Hill
You do not need new fascias just because the joints have opened. Sealing the joints tidies them up as long as the boards are in good condition. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Herne Hill buildings and the weather
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. Historic houses like Kingswood House (about 1.7 miles south) are a reminder that the area around Herne Hill 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.
Schools such as Judith Kerr Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near North Dulwich station, leaking gutter joints on a rental are best caught before they stain the walls. For an older house near a landmark such as Saint Faith's, an extension built onto an older house moves differently, and the joint between them takes the strain.
Herne Hill is about 3 miles south of London, in Greater London. Jobs in Herne Hill get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Our area takes in 764 places across Greater London, large and small.
Here we cover the SE22, SW2 and SE24 postcode area for gutter sealing.

Around Herne Hill
Locally, jobs take us to homes and businesses close to The Charter School, Half Moon pub and Belair Park, among other places. There’s a railway station in Herne Hill itself: North Dulwich station. A little further out are Surrey Quays Shopping Centre (3.5 miles north-east) and House of Dreams Museum (0.7 miles north-east). For a walk, there’s Battersea Park Lake and Knight's Hill.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep downpipes clear
- Look along the fascias for open joints
- Get leaks sealed before the wet months
- Have sagging gutters refixed early
Make sure downpipes are not blocked, so water can get away. A blocked pipe backs water up to the joints.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it while the frame is sound.
When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Boards that have decayed or split
- Blocked downpipes
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- Roofline trims
- Gutter joints
- uPVC fascias
- Soffit joints
- Garage door frames
- Gutter end caps
What the job involves on each surface
Soffit joints
Open soffit joints let draughts in. A neat seal closes them.
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
