Gutter sealing in Potters Bar, done properly
A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Sealing it is quick if the gutter is otherwise in good order. Typical jobs include end caps that drip every time it rains and earlier gutter repairs that have peeled off, on garage door frames, gutter joints and soffit joints.
In a town like Potters Bar, older houses with traditional gutters sit alongside newer estates with uPVC rooflines and rendered walls. Gutter joints, fascia trims and the movement joints in newer brickwork all need sealant that can flex.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What else we do in Potters Bar
Walls and rooflines in Potters Bar
With historic houses such as Wyllyotts Manor (about 0.4 miles west) nearby, there’s older building stock in the area around Potters Bar as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Letting a property close to Potters Bar station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. For site and facilities teams at buildings such as Ladbrooke Junior Mixed and Infant School, larger buildings have long runs of movement joint that eventually need resealing.

What we’re called out for in Potters Bar
Sealant laid on a wet or dirty joint fails early. Rushed repairs often do not last long for this reason.
These are the problems we are asked about most:
- Leaking gutter joints and stop ends
- Rain getting in around a garage door
- Old gutter sealant that has let go
- Open joints in fascias and soffits
If you live in an older home near St. Mary's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Sort out a dripping joint early
- Clean out the gutters once or twice a year
- Rest ladders on the wall, not the gutter
- Have sagging gutters refixed early
Keep the gutters clear of leaves and moss so water does not sit on the joints. Water left in a gutter tests every joint.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.
What the job involves on each surface
Soffit joints
Soffit joints are sealed in a colour to suit, where one is available.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a small job to fix.
