DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Gutter sealing in Kew, done properly
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed using a sealant made for outdoor use. We work on gutter joints, roofline trims and soffit joints, and the jobs we see most are failed sealant on a garage door frame and old gutter sealant that has let go.
Modern London flats rely on sealed movement joints and cladding joints. 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes an hour or two for a few joints, longer for a full run for a typical job. In Kew, 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 where the water is coming from and check the gutter isn’t broken or sagging.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant won’t bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.
Getting ready for the visit
- Keep pets and children clear of the area while we work

Historic houses like Kew Palace (about 0.7 miles west) are a reminder that the area around Kew 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. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
For landlords with property near Chiswick station, leaking gutter joints on a rental are best caught before they stain the walls. Schools such as Grove Park Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What else we do in Kew
Landlords, agents and businesses in Kew
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Do you need gutter sealing in Kew?
A sealant applied to a damp or dirty joint won’t bond. Rushed repairs often don’t last long for this reason.
The problems people normally mention when they call are:
- Old sealant on roofline trims that has split
- Stop ends leaking at the end of a run
- Wet patches on the wall under a gutter joint
- Quick sealant fixes on gutters that didn’t last
If you live in an older home near St Paul's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Questions from Kew
Do you work for landlords with property near Chiswick station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Can parking be tricky for a visit in Kew?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
What guarantee comes with the job?
There’s a 12-month guarantee on every job, gutter and fascia work included.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
What about gutters on a second or third storey?
Low-level work is easiest. For anything higher, we will confirm what access is needed once we know more.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long does gutter sealing take?
It depends on the size of the job, but most jobs take a few hours, depending on the number of joints and the access. We’ll give you a better idea when we quote.
What does gutter sealing cost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Why deal with it now?
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Cleaning out and drying the joint first is what makes it last. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Kew.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
