Gutter sealing in West Kensington
Across West Kensington, we reseal gutter joints, end caps and roofline trims. Low-level work is straightforward, and for higher work, tell us about access and we will confirm what’s needed. If you have rain getting in around a garage door and earlier gutter repairs that have peeled off, we can help.
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.

West Kensington questions
Can you help a landlord with a rental near Kensington Olympia station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is parking an issue for gutter sealing in West Kensington?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Is the work guaranteed?
You get our 12-month guarantee on every job.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
Do you clean gutters?
We clear debris around the joints we’re sealing. A full clean of the gutters isn’t part of it.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Can you fit new guttering?
No, we reseal joints and trims. Replacement needs a gutter installer or roofer.
How we quote for gutter sealing
Your quote is based on your job. We look at:
- The old material and how stubborn it is
- Access and height
- Mould in or behind the old joints
- The amount of work
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- The rough size of the job
- Whether it’s a home or a business
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Landlords, agents and businesses in West Kensington
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured.
Why deal with it now?
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right before the damage spreads. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in West Kensington, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Signs you need gutter sealing in West Kensington
Gutter joints depend on seals that wear out. Temperature changes make gutters move, and old seals crack or slip.
Common reasons people contact us include:
- Failed sealant on a garage door frame
- Leaking gutter joints and stop ends
- Old sealant on roofline trims that has split
- Earlier gutter repairs that have peeled off
For an older house near a landmark such as St Cuthbert's, older walls, gutters and the joints where extensions meet them need a flexible sealant.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to a few hours in most cases. In West Kensington, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents 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.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

What gutter sealing looks like in West Kensington
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Garden Lodge (about 0.4 miles north-east) are a reminder that the area around West Kensington 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.
