About our gutter sealing in Southington
Gutter and fascia replacement isn’t our trade, and nor is roofing. Sealant fixes joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. If you’re dealing with end caps that drip every time it rains and internal damp traced to a gutter joint, we can put it right, whatever the surface.
In a village or hamlet like Southington, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
All our work is covered by a one-year guarantee, wherever you are in Hampshire.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Look for streaks or damp on the wall below gutters
- Look at the gutters while it’s raining
- Do not leave a sagging gutter
- Clear leaves and moss from the gutters
A sagging gutter needs its brackets checked. If it drops, the joints will open.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
What gutter sealing looks like in Southington
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 Overton Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Leave it or put it right?
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. Older cottages and farmhouses around Southington can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Do you need gutter sealing in Southington?
A sealant applied to a damp or dirty joint will not bond. Some quick repairs peel off within a season or two for this reason.
Keep an eye out for any of the following:
- Old sealant on roofline trims that has split
- Fascia boards with gaps between them
- Damp on an inside wall under a dripping gutter
- Leaking gutter joints and stop ends
Rented homes near Overton station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.
Roofline trims
Sealing roofline trims is joint work only. A roofer deals with the roof itself.
