Advice
About our gutter sealing in Clerkenwell
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We work on roofline trims, uPVC fascias and gutter end caps, and common reasons people get in touch are wet patches on the wall under a gutter joint and dripping gutter ends.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
Each job carries a 12-month guarantee, large or small.

How to look after the new joints
After the cure time, these simple habits help:
- Keep the gutters clear of debris
- Check the gutters during heavy rain
- Keep ladders off the guttering
- Get leaks sealed before the wet months
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
Clerkenwell buildings and the weather
Historic houses like Dr Johnson's House (about 0.8 miles south) are a reminder that the area around Clerkenwell has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Managing a site like St Peter and St Paul RC Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Clerkenwell is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What affects the cost of gutter sealing
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The old material and how stubborn it is
- The amount of work
- The type of sealant required
- Whether the work is at height
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before any work starts.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- What’s wrong with the joints now
- Any access issues, like height or stairs
- A few pictures by email, if you can

What we are called out for in Clerkenwell
Sealant laid on a wet or dirty joint fails early. Rushed repairs often don’t last long for this reason.
The problems people generally mention when they call include:
- Quick sealant fixes on gutters that didn’t last
- Open joints in fascias and soffits
- Trim joints where the sealant has failed
- Rain getting in around a garage door
Rented homes near Farringdon station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
What your quote should include
- Who does the work, and how experienced they are
- Which colour the sealant will be
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
Leave it or put it right?
Sealant will not clear a blocked downpipe. We check the cause first and point you to the right trade if needed. 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.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
Why book with us
- Old sealant always removed completely
- White, clear, grey or another colour, product permitting
- 20+ years of sealant experience
- Anti-fungal silicone where joints get wet
