Gutter sealing in Sharpthorne
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. We work on garage door frames, gutter end caps and uPVC fascias, and people most often call us about internal damp traced to a gutter joint and failed sealant on a garage door frame.
Outside joints can only be sealed when they’re dry, so work in Sharpthorne is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All our work is covered by a 12-month guarantee.

Advice
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
What gutter sealing looks like in Sharpthorne
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. Historic houses like Priest House (about 0.5 miles west) are a reminder that the area around Sharpthorne 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.
Homes close to St Margaret's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. If you let a flat or house near East Grinstead station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Why it’s worth doing now in Sharpthorne
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right before the damage spreads. In a small place like Sharpthorne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Look along the fascias for open joints
- Keep the gutters clear of debris
- Keep ladders off the guttering
- Have sagging gutters refixed early
Clear the gutters once or twice a year so water doesn’t sit on the joints. Standing water strains every seal.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.

Common problems we fix in Sharpthorne
Sagging sections pull joints apart. Sealing will not hold if the gutter keeps dropping so the brackets need attention first.
If you can see any of these, it’s time to have the joints looked at:
- Water running down the wall below the gutter
- Gaps along fascia and soffit joints
- Stop ends leaking at the end of a run
- Quick sealant fixes on gutters that didn’t last
Managing a site like West Hoathly CofE Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
