Gutter sealing for homes and businesses in Brockley Hill
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. They’re sealed in a matching colour where one is available. Typical jobs include water running down the wall below the gutter and stop ends leaking at the end of a run, on gutter joints, garage door frames and gutter end caps.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
Big or small, you get the same one-year guarantee.

What gutter sealing looks like in Brockley Hill
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Headstone Manor (about 3.4 miles south-west) nearby, there’s older building stock in the area around Brockley Hill as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as London Academy, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain.

Advice
FAQs for Brockley Hill
Can you do gutter sealing in Brockley Hill?
Yes. Our work covers London and the South East, and Brockley Hill is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Is parking a problem for a job in Brockley Hill?
Parking in Brockley Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we will ask.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you install new fascias or gutters?
That is not something we do. We seal joints and replacement is a job for an installer.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Water backing up from a blocked pipe
- Gutters that have dropped or pulled away
- Rotten or damaged fascia boards
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- uPVC fascias
- Gutter end caps
- Garage door frames
- Soffit joints
- Gutter joints
- Roofline trims
DIY versus a professional finish
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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Leave it or put it right?
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job compared with treating damp later. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Brockley Hill.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.

When to call us in Brockley Hill
When a gutter sags, its joints open. Sealing will not hold if the gutter keeps dropping, so the gutter needs refixing first.
It’s worth asking for a quote if you see:
- Damp on an inside wall under a dripping gutter
- Garage door frames letting rain in
- Streaks down the brickwork from a leaking joint
- End caps that drip every time it rains
Brockley Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep ladders off the guttering
- Look for streaks or damp on the wall below gutters
- Keep the gutters clear of debris
- Check the gutters during heavy rain
Leave the new sealant to cure as we advise before poking or cleaning near it.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job while the frame is sound.
