About our gutter sealing in Bayswater
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. If you’re dealing with old sealant on roofline trims that has split and streaks down the brickwork from a leaking joint, we can help.
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.
Big or small, it’s backed by our 12-month guarantee.

Outside joints around Bayswater
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. Historic houses like Kensington Palace (about 0.4 miles south-east) are a reminder that the area around Bayswater 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.
Letting a property close to London Paddington station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. In the older streets around Essex Street Chapel, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Bayswater is about 1 mile north-east of Kensington, in Greater London. Anywhere in W2, our applicators can take on gutter sealing. Bayswater is one of 764 places in Greater London we cover for gutter sealing.

How we quote for gutter sealing
There’s no set price list. What we look at:
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- The number of rooms or windows
- Working hours on commercial sites
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

When to call us in Bayswater
A sealant applied to a damp or dirty joint won’t bond. Some quick repairs peel off within a season or two.
These are the problems we’re asked about most:
- Leaking gutter joints and stop ends
- Failed sealant on a garage door frame
- Dripping gutter ends
- Earlier gutter repairs that have peeled off
As a London address, Bayswater can be tricky for parking: let us know about parking bays, permits or a driveway.
What your quote should include
- Which sealant they’ll use, and why
- What preparation is included
- What the cure time is
- How much experience the applicator has
Why act early in Bayswater
Replacing fascias because of open joints is normally unnecessary. Sealing the joints tidies them up if the boards are sound. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check fascia and soffit joints for gaps
- Keep the gutters clear of debris
- Check that water runs out of the downpipes
- Sort out a dripping joint early
Leave the new sealant to cure as we advise and avoid disturbing it.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it.
Common questions in Bayswater
Do you work for landlords with property near London Paddington station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover Bayswater for gutter sealing?
Yes. We work across London and the South East, and Bayswater is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available and agree one before work begins.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Will you clear out my gutters?
We clear debris around the joints we’re sealing. Full gutter cleaning is a separate job.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can a leaking gutter joint be sealed?
Most of the time. If the gutter is sagging or cracked, sealing will not last and we will say so.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured.
