Gutter sealing for homes and businesses in Cambridge Heath
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where possible. If you have damp on an inside wall under a dripping gutter and dripping gutter ends, we can help, whatever the surface.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Cambridge Heath, tell us how high the joints are and how to reach the back of the building.
Big or small, you get the same 12-month guarantee in Cambridge Heath and across Greater London.

When to call us in Cambridge Heath
Gutter joints rely on seals that age. Temperature changes make gutters move and that movement opens up tired joints.
Look out for any of the following:
- Stop ends leaking at the end of a run
- Leaking gutter joints and stop ends
- Open joints in fascias and soffits
- Failed sealant on a garage door frame
For an older house near a landmark such as St James-the-Less, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- What the cure time is
- Whether they’re fully insured
- Which colour the sealant will be
- How the joint is cleaned and prepared

Common questions in Cambridge Heath
Is parking a problem for a job in Cambridge Heath?
Parking in Cambridge Heath, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for landlords with property near Cambridge Heath station?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Is sealant enough for a gutter that has dropped?
Not for long. The movement opens the joint again so the gutter has to be refixed first.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
How we quote for gutter sealing
Call for a quick quote. What matters most is:

Cambridge Heath buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Sutton House (about 1 mile north) are a reminder that the area around Cambridge Heath 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.
As a London address, Cambridge Heath can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Cambridge Heath station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours, depending on the number of joints and the access, depending on how much there is to do. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep downpipes clear
- Look at the gutters while it’s raining
- Rest ladders on the wall, not the gutter
- Look for streaks or damp on the wall below gutters
Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Water left in a gutter tests every joint.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards and the wall below.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Leave it or put it right?
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 Cambridge Heath, the repair is bigger than the sealant job would have been.
