Signs you need gutter sealing in Wallington
Gutter joints rely on seals that age. Temperature changes make gutters move and that movement opens up tired joints.
Look out for these signs:
- Water dripping where gutter sections meet
- Fascia boards with gaps between them
- End caps that drip every time it rains
- Rain getting in around a garage door
For an older house near a landmark such as Church of the Holy Trinity, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Before booking anyone
- How hidden problems are handled
- The length of the guarantee
- Whether all the old sealant comes out first
- How much experience the applicator has
Gutter sealing in Wallington, done properly
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first, then dry the joint before sealing. We work on gutter end caps, gutter joints and garage door frames, and people most often call us about old gutter sealant that has let go and damp patches inside below a leaking gutter.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. In a converted house in Wallington, it’s worth checking who is responsible for the outside before booking.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why act early in Wallington
A dripping gutter joint keeps wetting the same patch of wall. Left, it can stain walls and lead to damp so early sealing is worthwhile. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Common questions in Wallington
Is parking a problem for a job in Wallington?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
I let a flat near Wallington station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
What does gutter sealing cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
How long will you be here?
Most jobs take a few hours, depending on the number of joints and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep an eye out for wet patches below a joint
- Clean out the gutters once or twice a year
- Check the gutters during heavy rain
- Keep ladders off the guttering
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
Early sealing limits how much water hits the wall. We will let you know if the gutter needs more than sealant.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Quotes for gutter sealing in Wallington
We do not publish a price list, because jobs vary so much. The quote depends on:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Whether the work is at height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Any access issues, like height or stairs

Gutter sealing in Wallington: local notes

As a London address, Wallington can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Holy Trinity CofE Junior School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
