Gutter sealing in Blendon
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we’ll tell you. Common call-outs are for water dripping where gutter sections meet and streaks down the brickwork from a leaking joint, on uPVC fascias, garage door frames and roofline trims.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Blendon, check the lease for who looks after the outside.
There’s a 12-month guarantee on every job, whatever its size.

Why act early in Blendon
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint, resealing is the sensible fix. If it has failed, we’ll tell you. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Blendon.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.

Walls and rooflines in Blendon
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 Danson House (about 0.7 miles north) nearby, there’s older building stock in the area around Blendon as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Blackfen School for Girls, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as St James the Great, the joints between older walls, newer extensions and the roofline need a sealant that can move.

- Wet patches on the wall under a gutter joint
- Old gutter sealant that has let go
- Damp patches inside below a leaking gutter
- Trim joints where the sealant has failed
Blendon is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
FAQs for Blendon
Is parking a problem for a job in Blendon?
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.
Is Blendon in your area for gutter sealing?
Yes, Blendon is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you clean gutters?
Only around the joints we seal because the joint must be clean. A full gutter clean is a separate job.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Blendon.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Keeping the joints in good condition
So the new joints stay in good condition:
- Make sure downpipes aren’t blocked
- Get a dropping gutter looked at quickly
- Get leaks sealed before the wet months
- Look for streaks or damp on the wall below gutters
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours, depending on the number of joints and the access, depending on the size of the job. In Blendon, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Getting ready for the visit
