Gutter sealing in Broad Colney
We seal leaking gutter joints, end caps, fascia and soffit joints, along with roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. If you have dripping gutter ends and fascia boards with gaps between them, we can help, on soffit joints, gutter joints and roofline trims alike.
In a village or hamlet like Broad Colney, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
You get a 12-month guarantee, the same in Broad Colney as everywhere else we work.

The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes anything from an hour or two to a few hours. In a small place like Broad Colney, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Preparing for the visit
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Gutter joints
A dripping joint doesn’t always mean a failed gutter. Resealing is usually enough.
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
What gutter sealing looks like in Broad Colney
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. With historic houses such as High Elms Manor (about 4.1 miles west) nearby, there’s older building stock in the area around Broad Colney as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St Peter include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Saint Bernadette Catholic Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

What we seal
- Gutter end caps
- Gutter joints
- Garage door frames
- uPVC fascias
- Soffit joints
- Roofline trims
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep downpipes clear
- Look at the gutters while it’s raining
- Clear leaves and moss from the gutters
- Rest ladders on the wall, not the gutter
A sagging gutter needs its brackets checked. If it drops, the joints will open.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Other services in Broad Colney
Do you need gutter sealing in Broad Colney?
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end and runs down the wall.
Any of these means the joints need attention:
- Internal damp traced to a gutter joint
- Fascia boards with gaps between them
- Earlier gutter repairs that have peeled off
- Water dripping where gutter sections meet
If you let a flat or house near Park Street station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
