Gutter sealing in Waddon
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame with an exterior sealant. We work on gutter joints, uPVC fascias and soffit joints, and the jobs we see most are trim joints where the sealant has failed and open joints in fascias and soffits.
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.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What gutter sealing looks like in Waddon
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 Addington Palace (about 3.1 miles east) are a reminder that the area around Waddon has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Waddon is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Schools such as Aerodrome Primary Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Common problems we fix in Waddon
When a gutter sags, its joints open. Resealing a sagging joint won’t last, so the gutter needs refixing first.
Common reasons people contact us are:
- Wet patches on the wall under a gutter joint
- Cracked sealant along roofline trims
- Internal damp traced to a gutter joint
- Garage door frames letting rain in
Homes close to Church of St George include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

How it works
At the end, we look at the finished work together. The work normally takes an hour or two for a few joints, longer for a full run, depending on how much there is to do. In Waddon, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we trace the drip and check the gutter isn’t damaged.
- We remove the old sealant and clean 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.
Getting ready for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit

Advice
What happens if it’s left?
A dripping stop end can soak the wall right through the wet months. It’s a small job to put right before the damage spreads. In a flat in Waddon, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Looking after it afterwards
Aftercare is simple:
- Deal with a drip before winter
- Glance at the soffit joints now and then
- Clear leaves and moss from the gutters
- Make sure downpipes are not blocked
Keep downpipes clear so the gutter can drain. A blocked pipe backs water up to the joints.
A drip from a gutter joint won’t stop on its own. Water keeps hitting the same part of the wall, which can lead to staining and damp.
Landlords, agents and businesses in Waddon
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We also work for property managers and facilities teams in Waddon and across Greater London. Several sites can go on one quote, and we are fully insured for the work.
Common questions in Waddon
Is parking an issue for gutter sealing in Waddon?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Is Waddon in your area for gutter sealing?

Can I choose the sealant colour?

We do. Our work is the joints, and if a board is damaged, we’ll tell you.

That depends on the amount of work, but most jobs take an hour or two for a few joints, longer for a full run. We’ll tell you when we quote.
