Gutter sealing for homes and businesses in Lower Caversham
Our work covers gutter joints and end caps as well as fascias and soffits plus roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. Common call-outs are for earlier gutter repairs that have peeled off and garage door frames letting rain in, across uPVC fascias, roofline trims and gutter end caps.
Around Lower Caversham, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
All our work is covered by our 12-month guarantee.

When to call us in Lower Caversham
Leaves and moss hold water in the gutter. Water that can’t drain works its way through a weak joint and leaks out.
Most people get in touch when they notice something like this:
- Wet patches on the wall under a gutter joint
- Old sealant on roofline trims that has split
- Drips from gutter joints and end caps
- Rain getting in around a garage door
In the older streets around St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Walls and rooflines in Lower Caversham
Historic houses like Mapledurham House (about 3.5 miles north-west) are a reminder that the area around Lower Caversham 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as St Anne's Catholic Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Reading station? Then leaking gutter joints on a rental are best caught before they stain the walls.

Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.

Is gutter cleaning part of the job?
We clean the joints we’re sealing and any debris nearby is cleared. A full gutter clean is a separate service.
What does gutter sealing cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.

How to look after the new joints
So the new joints stay in good condition:
- Make sure downpipes aren’t blocked
- Clean out the gutters once or twice a year
- Don’t leave a sagging gutter
- Check the gutters during heavy rain
Clear the gutters once or twice a year, so water drains away past the joints. Water left in a gutter tests every joint.
The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.
How the visit works

- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.

Why deal with it now?
You don’t need new fascias just because the joints have opened. A neat seal closes the gaps if the boards are sound. Around Lower Caversham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
