Gutter sealing in Old Chiswick
We don’t replace gutters, fascias or roofs. Sealant fixes joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. Common call-outs are for garage door frames letting rain in and damp on an inside wall under a dripping gutter, on roofline trims, gutter end caps and soffit joints.
Modern London flats rely on sealed movement joints and cladding joints. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a few hours in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Old Chiswick. A visitor permit or a nearby bay makes the visit run more smoothly.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Advice
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Look along the fascias for open joints
- Make sure downpipes are not blocked
- Get a dropping gutter looked at quickly
- Clear leaves and moss from the gutters
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.
Your questions about gutter sealing in Old Chiswick
Do you work for landlords with property near Chiswick station?
Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can parking be tricky for a visit in Old Chiswick?
Parking in Old Chiswick, 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.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Is gutter cleaning part of the job?
Only around the joints we seal because the joint must be clean. Cleaning the whole run is a separate job.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
How long does gutter sealing take?
Most jobs take anything from an hour or two to a few hours, including the preparation. We will confirm how long when we quote.

- Blocked downpipes

Why act early in Old Chiswick
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job before the damage spreads. 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.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why Old Chiswick clients choose us
- Neat joints and a tidy finish
- An ARBOMaster approved applicator
- We agree the colour with you first
- Sealant colour chosen to suit
Old Chiswick buildings and the weather
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. Historic houses like Hogarth's House (about 0.4 miles west) are a reminder that the area around Old Chiswick has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Old Chiswick is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St. Nicholas Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Old Chiswick is about 2 miles south of Acton, in Greater London.

Do you need gutter sealing in Old Chiswick?
Gutter joints rely on seals that age. Temperature changes make gutters move and that movement opens up tired joints.
If you can see any of these, it’s time to have the joints looked at:
- Gaps along fascia and soffit joints
- Dripping gutter ends
- Quick sealant fixes on gutters that didn’t last
- Damp patches inside below a leaking gutter
If you look after a building such as The William Hogarth Primary School, larger buildings have long runs of movement joint that eventually need resealing.
