About our gutter sealing in Mersham
It’s easy to live with a dripping gutter joint, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. Typical jobs include fascia boards with gaps between them and damp on an inside wall under a dripping gutter, on soffit joints, gutter joints and uPVC fascias.
In a village or hamlet like Mersham, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Mersham questions
I let a flat near Ashford International station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like Mersham?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Is gutter cleaning part of the job?
We clean the joints we’re sealing and clear debris we find nearby. A full gutter clean is a separate service.
Will sealing fix a sagging gutter?
Not on its own. If the gutter sags, the joints keep opening, so the brackets need fixing first.
What about gutters on a second or third storey?
Low-level work is easiest. For anything higher, we will confirm what access is needed once we know more.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Walls and rooflines in Mersham
Historic houses like Westenhanger Castle (about 4.7 miles east) are a reminder that the area around Mersham 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Mersham Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Ashford International station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near Church of St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How the job changes by surface
Roofline trims
Trim joints are cut out and resealed suited to the material.
Garage door frames
Failed sealant around a garage door frame lets water in. It’s removed and renewed.
Why deal with it now?
A new garage door isn’t needed for a leaking frame. Sealing the frame normally stops it. Around Mersham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Have sagging gutters refixed early
- Rest ladders on the wall, not the gutter
- Clean out the gutters once or twice a year
- Get leaks sealed before the wet months
Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Standing water strains every seal.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
