What gutter sealing looks like in New Ash Green

Historic houses like Cobham College (about 4.3 miles east) are a reminder that the area around New Ash Green 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

If you let a flat or house near Longfield station, leaking gutter joints on a rental are best caught before they stain the walls. For site and facilities teams at buildings such as New Ash Green Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Gutter sealing in New Ash Green

Failed sealant round a garage door frame lets rain blow in. The frame joint is cut out and resealed with an exterior sealant. Typical jobs include damp patches inside below a leaking gutter and trim joints where the sealant has failed, on soffit joints, gutter joints and roofline trims.

Somewhere as small as New Ash Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.

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.

FAQs for New Ash Green

Can you help a landlord with a rental near Longfield station?

Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.

Do you cover smaller places like New Ash Green?

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

How long before the joint can be used?

Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

Are you fully insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Is it OK to seal over old sealant?

No. The old sealant always comes out first.

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little.

Surface by surface

Garage door frames

Garage door frames let rain in when their sealant fails. It’s removed and renewed.

Soffit joints

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

Why deal with it now?

You don’t need new fascias just because the joints have opened. A neat seal closes the gaps if the boards are sound. Where a wall is exposed, as many are in small places like New Ash Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the number of joints and the access. In a small place like New Ash Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we agree which joints need sealing.
  2. Each joint is cleaned and any old sealant removed.
  3. We make sure everything is dry.
  4. The sealant is applied and finished.

When to call us in New Ash Green

Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract and that movement opens up tired joints.

Any of these means the joints need attention:

  • Stop ends leaking at the end of a run
  • Internal damp traced to a gutter joint
  • Water dripping where gutter sections meet
  • Garage door frames letting rain in

If you live in an older home near Parish Church of Saint Peter and Saint Paul, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Get leaks sealed before the wet months
  • Look along the fascias for open joints
  • Make sure downpipes are not blocked
  • Watch for drips in a downpour

While checking gutters, glance at the fascia joints too. A small split is quicker to put right.

Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.
