Gutter, fascia & soffit sealing in Blackgang, Isle of Wight
Gutter and fascia joints in Blackgang need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Old sealant on roofline trims that has split
- Leaking gutter joints and stop ends
- Earlier gutter repairs that have peeled off
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Gutter sealing for homes and businesses in Blackgang
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed with an exterior sealant. We work on uPVC fascias, gutter end caps and soffit joints, and common reasons people get in touch are rain getting in around a garage door and cracked sealant along roofline trims.
Somewhere as small as Blackgang, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months.

When to call us in Blackgang
Sagging sections pull joints apart. Resealing a sagging joint won’t last so the brackets need attention first.
The most common problems we see are:
- Fascia boards with gaps between them
- Damp on an inside wall under a dripping gutter
- Leaking gutter joints and stop ends
- Dripping gutter ends
If you look after a building such as Niton Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Other services in Blackgang
What gutter sealing looks like in Blackgang
Blackgang is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Wolverton Manor (about 4.1 miles north-west) are a reminder that the area around Blackgang has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near St Andrew's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Blackgang is about 6 miles south-west of Shanklin, in the Isle of Wight. Homes, rented property, offices and hotels in Blackgang can book us for gutter sealing, old or new, large or small.

Your questions about gutter sealing in Blackgang
Does living near the coast affect gutter sealing in Blackgang?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Will you come out to Blackgang?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Do you clean gutters?
The joints we seal are cleaned out and clear debris we find nearby. A full gutter clean is a separate service.
Is sealant enough for a gutter that has dropped?
Not for long. The joint will pull apart so the gutter has to be refixed first.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across the Isle of Wight.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Why act early in Blackgang
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. Where a wall is exposed, as many are in small places like Blackgang, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What happens on the day
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. The work generally takes a few hours, depending on the number of joints and the access. Somewhere as small as Blackgang, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
