Gutter sealing for West Brompton homes and businesses

Gutter sealing in West Brompton, done properly

Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. If you have drips from gutter joints and end caps and cracked sealant along roofline trims, we can put it right, on gutter joints, garage door frames and uPVC fascias alike.

Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What affects the cost of gutter sealing

Call for a quick quote. The main things that affect it are:

  • Access and height
  • The number of rooms or windows
  • Working hours on commercial sites
  • The old material and how stubborn it is

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

What we need to know

When you contact us, these details help:

  • Whether it’s a home or a business
  • A few pictures by email, if you can
  • What’s wrong with the joints now
  • The address or postcode of the job

Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand.

How to look after the new joints

After the cure time, these simple habits help:

  • Look along the fascias for open joints
  • Watch for drips in a downpour
  • Get leaks sealed before the wet months
  • Have sagging gutters refixed early

Keep the gutters clear of leaves and moss so water does not sit on the joints. Standing water strains every seal.

Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.

How the visit works

Most of a good job is in the 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. For a job in West Brompton, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  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. An exterior or gutter sealant is applied to the joint.
  5. We check the run and clear any debris we find while we are there.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions

Advice

Common problems we fix in West Brompton

Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits after some years.

People normally contact us after spotting something like this:

  • Damp on an inside wall under a dripping gutter
  • End caps that drip every time it rains
  • Garage door frames letting rain in
  • Drips from gutter joints and end caps

Rented homes near West Brompton station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

Questions to ask before booking

  • How the colour is chosen
  • Whether they seal over old material or remove it
  • How long the guarantee is
  • Who does the work, and how experienced they are

Choosing a sealant specialist

DIY versus a professional finish

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Leave it or put it right?

Replacing guttering is a much bigger job than sealing joints. Where the gutter is in good order and only a joint leaks, resealing is the sensible fix. If it’s broken or sagging, a gutter installer needs to look. In a flat in West Brompton, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What about gutters on a second or third storey?

That depends on the building. Let us know the height and the ground below and we will confirm what’s needed.

Do you seal gaps in fascias and soffits?

Yes. Our work is the joints, and if a board is damaged, we’ll tell you.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before resealing.

How long should I leave it?

It depends on the product. We tell you how long to leave it before we go.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can new sealant go over the old?

No. We remove every bit of old sealant first.

What gutter sealing looks like in West Brompton

Historic houses like Garden Lodge (about 0.6 miles north) are a reminder that the area around West Brompton 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. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.

Schools such as St Cuthbert with St Matthias CofE Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of St Luke, an extension built onto an older house moves differently, and the joint between them takes the strain.
