What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It normally takes anything from an hour or two to a few hours. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we trace the drip and check the gutter is not damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Clear the area around the work

Advice
How we handle gutter sealing in Chiswick
We don’t replace gutters, fascias or roofs. What sealant does is close joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. If you have quick sealant fixes on gutters that didn’t last and cracked sealant along roofline trims, we can put it right, whatever the surface.
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, and both kinds of building are found across London.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Aftercare tips
Looking after new joints is easy:
- Keep downpipes clear
- Check fascia and soffit joints for gaps
- Deal with a drip before winter
- Keep ladders off the guttering
Look at fascia and trim joints when you’re checking the gutters. Splits are easier to seal early.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall, which can lead to staining and damp.
Honest limits
Before booking, it’s worth knowing the limits:
- Brackets that have snapped or loosened
- Blocked downpipes
- Leaks from the roof rather than a joint
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Walls and rooflines in Chiswick
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hogarth's House (about 0.2 miles south-west) are a reminder that the area around Chiswick has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like The William Hogarth Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Chiswick is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Do you need gutter sealing in Chiswick?
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:
- Fascia boards with gaps between them
- End caps that drip every time it rains
- Rain getting in around a garage door
- Internal damp traced to a gutter joint
For landlords with property near Chiswick station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
