Gutter Sealing in East Ham
Gutter and fascia joints in East Ham need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Old sealant on roofline trims that has split
- Internal damp traced to a gutter joint
- Quick sealant fixes on gutters that didn’t last
Gutter sealing in East Ham, done properly
We do not replace gutters, fascias or roofs. Sealant fixes joints and it cannot mend broken brackets, split sections or blocked downpipes. If you have damp on an inside wall under a dripping gutter and drips from gutter joints and end caps, we can help, whatever the surface.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In East Ham, joints up high may need ladders or other access, which is worth talking through when you book.
We stand behind the work with a 12-month guarantee.

Walls and rooflines in East Ham
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
As a London address, East Ham can be tricky for parking: let us know about parking bays, permits or a driveway. If you look after a building such as St Michael's Catholic Primary School, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Barking station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Different surfaces, different methods
Gutter end caps
End caps take the pressure of water running along the gutter. A failed seal makes them leak.
Gutter joints
Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.
Why it’s worth doing now in East Ham
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Proper preparation is the difference. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in East Ham, the repair is bigger than a sealant job.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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. Everything old must be removed first.

How it works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job normally takes anything from an hour or two to a few hours, and we explain the cure time before we leave.

- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
