Gutter sealing in Alverstoke, done properly

Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough, as long as the gutter is sound. We work on uPVC fascias, garage door frames and soffit joints, and people most often call us about damp patches inside below a leaking gutter and dripping gutter ends.

In a village or hamlet like Alverstoke, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

A 12-month guarantee comes as standard.

Landlords, agents and businesses in Alverstoke

We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.

Surface by surface

Soffit joints

Open soffit joints let draughts in. We close them with a suitable sealant.

Gutter joints

A dripping joint does not always mean a failed gutter. Sealing the joint often stops it.

What we’re called out for in Alverstoke

End caps get knocked or pushed by water. If the seal fails, water escapes at the end and runs down the wall.

The most common problems we see are:

  • Old sealant on roofline trims that has split
  • Drips from gutter joints and end caps
  • Open joints in fascias and soffits
  • Old gutter sealant that has let go

If you live in an older home near The Little Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Aftercare tips

Aftercare is simple:

  • Make sure downpipes are not blocked
  • Get leaks sealed before the wet months
  • Check fascia and soffit joints for gaps
  • Rest ladders on the wall, not the gutter

Give the sealant the cure time we tell you and avoid disturbing it.

Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry.

The process

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes an hour or two for a few joints, longer for a full run. Somewhere like Alverstoke needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by tracing the leak and checking the gutter itself is sound.
  2. Old sealant and dirt are removed from the joint.
  3. The area is dried so the sealant can bond.
  4. We seal the joint with a sealant made for gutters and outdoor use.
  5. We check the run and clear any debris we find while we’re there.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us if parking is tricky
  • Keep children and pets away from the work area

Alverstoke buildings and the weather

Alverstoke 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. 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 Alverstoke Community Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Portsmouth Harbour station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Your questions about gutter sealing in Alverstoke

Is Alverstoke within the area you cover?

Yes, Alverstoke is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is gutter sealing in a coastal place like Alverstoke any different?

Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.

Do you work for landlords and businesses?

Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Will sealing fix a sagging gutter?

No. If the gutter sags, the joints keep opening so it needs refixing before sealing.

What about gutters on a second or third storey?

Single-storey and low-level gutters are straightforward. If it’s higher up, let us know and we will confirm the access.

Is there any odour?

It depends on the product. Some products have a noticeable smell, others very little.

How do I get a quote for gutter sealing in Alverstoke?

It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us and let us know what needs doing and where.

Why deal with it now?

A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job compared with treating damp later. Older cottages and farmhouses around Alverstoke can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Why us?

  • We leave the area clean and tidy
  • Domestic, commercial and hotel work
