About our gutter sealing in Lewknor
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first, then dry the joint before sealing. If you’re dealing with damp on an inside wall under a dripping gutter and fascia boards with gaps between them, we can help, on garage door frames, gutter end caps and soffit joints alike.
External sealant needs dry, clean surfaces, so work around Lewknor is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why act early in Lewknor
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. Older cottages and farmhouses around Lewknor can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

When to call us in Lewknor
Gutter joints depend on seals that wear out. Temperature changes make gutters move and that movement opens up tired joints.
It’s worth asking for a quote if you see:
- Leaking gutter joints and stop ends
- Trim joints where the sealant has failed
- Earlier gutter repairs that have peeled off
- Gaps along fascia and soffit joints
For site and facilities teams at buildings such as Lewknor Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- When the joint can take water or movement
- Whether you can choose the colour
- Whether VAT is included
- What happens if the job turns out different

What gutter sealing looks like in Lewknor
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Adwell House (about 1.6 miles north-west) are a reminder that the area around Lewknor has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Church of St Margaret, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep ladders off the guttering
- Have sagging gutters refixed early
- Look along the fascias for open joints
- Look at the gutters while it’s raining
Give the sealant the cure time we tell you and avoid disturbing it.
A leaking garage frame lets water reach stored items. A reseal sorts it while the frame is sound.
