Gutter sealing in Longford

What we cannot put right

Sealant isn’t the answer to every problem, and we will tell you before we start. It will not solve:

  • Cracked, split or warped gutter sections
  • Water backing up from a blocked pipe

Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

Surfaces we seal

  • uPVC fascias
  • Gutter joints
  • Soffit joints
  • Gutter end caps
  • Garage door frames
  • Roofline trims

Gutter sealing for homes and businesses in Longford

A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs if the gutter is not damaged. If you’re dealing with earlier gutter repairs that have peeled off and end caps that drip every time it rains, we can put it right.

Somewhere as small as Longford, 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.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Signs you need gutter sealing in Longford

Leaves and moss hold water in the gutter. Standing water finds the weakest joint and leaks out.

Signs it’s time to call us include:

  • Garage door frames letting rain in
  • Leaking gutter joints and stop ends
  • Open joints in fascias and soffits
  • Old sealant on roofline trims that has split

Rented homes near Heathrow Terminal 5 Rail station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

10 questions to ask before you book

What the job involves on each surface

uPVC fascias

We seal fascia joints, not replace the boards. Damaged boards need replacing by an installer.

Garage door frames

The joint between frame and brickwork moves and weathers. An exterior sealant suits them.

Walls and rooflines in Longford

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Frogmore House (about 4.3 miles west) are a reminder that the area around Longford 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.

In the older streets around Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Pippins School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Watch for drips in a downpour
  • Clear leaves and moss from the gutters
  • Get leaks sealed before the wet months
  • Check that water runs out of the downpipes

Leave the new sealant to cure as we advise before poking or cleaning near it.

A drip from a gutter joint will not stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.

What happens on the day

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on the number of joints and the access. For a village or hamlet like Longford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we agree which joints need sealing.
  2. Each joint is cleaned and any old sealant removed.
  3. The joints are dried.
  4. The sealant is applied and finished.
  5. The joints are checked once sealed.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky

Advice

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Leave it or put it right?

A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job compared with treating damp later. Where a wall is exposed, as many are in small places like Longford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

What you get with us

  • A choice of colours where the product allows
  • 180+ five-star Google reviews

Can you do gutter sealing in Longford?

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’ll tell you what we’re using.

Are you insured?

Yes. We’re fully insured, with over 20 years’ experience in sealant work.

Do you hold any approvals?

Very little: the area around the joints is protected first, and we tidy up before we go.

Will sealing fix a sagging gutter?

Sealant won’t hold a sagging gutter. A gutter installer needs to refix it.

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.
