Why act early in Trowley Bottom
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Proper preparation is the difference. In a small place like Trowley Bottom, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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. You’ll have a clear quote before any work starts, so you know where you stand.

Gutter sealing in Trowley Bottom, done properly
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where possible. If you have internal damp traced to a gutter joint and wet patches on the wall under a gutter joint, we can put it right, whatever the surface.
Somewhere as small as Trowley Bottom, homes and farm buildings often face open ground, 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.
Every job is covered by a one-year guarantee.

Soffit joints
Soffits sit under the eaves, where joints can open up. We seal them to close the gaps.
Gutter joints
Gutter joints move and sit in water. A gutter sealant made for the job holds best.

Outside joints around Trowley Bottom
Historic houses like Childwickbury Manor (about 4.5 miles south-east) are a reminder that the area around Trowley Bottom 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. London and the South East are among 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 Flamstead Village School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of St Leonard, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Harpenden station, leaking gutter joints on a rental are best caught before they stain the walls.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Problems with the roof covering
- Boards that have decayed or split
- Gutters that have dropped or pulled away
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Garage door frames
- Roofline trims
- Gutter joints
- Soffit joints
- uPVC fascias
- Gutter end caps
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Make sure downpipes are not blocked
- Keep ladders off the guttering
- Get a dropping gutter looked at quickly
- Watch the wall under the gutters for staining
If a gutter starts to sag, get the brackets looked at. If it drops, the joints will open.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.
