- Water running down the wall below the gutter
About our gutter sealing in Old Coulsdon
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. We work on uPVC fascias, garage door frames and gutter end caps, and people most often call us about wet patches on the wall under a gutter joint and leaking gutter joints and stop ends.
Outside work in London starts with access: side passages, upper floors and where to park. In Old Coulsdon, joints up high may need ladders or other access, which is worth talking through when you book.
Whatever the size of the job, you get the same 12-month guarantee.

What happens if it’s left?
If the problem is a blocked downpipe, sealing won’t help. We look at what’s really happening and tell you if something else is needed. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Outside joints around Old Coulsdon
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Coulsdon South station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you look after a building such as Keston Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Aftercare tips
Looking after new joints is easy:
- Don’t lean ladders against the gutter itself
- Have sagging gutters refixed early
- Look at the gutters while it’s raining
- Clean out the gutters once or twice a year
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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 fails, we can still redo it.
What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes an hour or two for a few joints, longer for a full run, depending on the amount of work. In a London area like Old Coulsdon, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First we trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
How to prepare
- Tell us if parking is tricky
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Questions from Old Coulsdon
Can you do gutter sealing in Old Coulsdon?
Yes. We work across London and the South East, and Old Coulsdon is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is parking a problem for a job in Old Coulsdon?
Parking in Old Coulsdon, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is the work guaranteed?
Every job comes with our 12-month guarantee.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you need gutter sealing in Old Coulsdon?
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end and runs down the wall.
The most common problems we see are:
- Wet patches on the wall under a gutter joint
- Garage door frames letting rain in
- End caps that drip every time it rains
- Drips from gutter joints and end caps
Old Coulsdon is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
