Gutter sealing for Catford homes and businesses

What we are called out for in Catford

When a gutter sags, its joints open. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.

Look out for any of the following:

  • Dripping gutter ends
  • Water dripping where gutter sections meet
  • Failed sealant on a garage door frame
  • Water running down the wall below the gutter

As a London address, Catford can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What your quote should include

  • Is VAT in the price?
  • Whether all the old sealant comes out first
  • What guarantee comes with the work
  • How the joint is cleaned and prepared

Choosing a sealant specialist

Gutter sealing for homes and businesses in Catford

We seal leaking gutter joints, end caps, fascia and soffit joints, along with roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. If you have earlier gutter repairs that have peeled off and stop ends leaking at the end of a run, we can help, whatever the surface.

Outside work in London starts with access: side passages, upper floors and where to park. For a home in Catford, tell us how high the joints are and how to reach the back of the building.

All our work is covered by a 12-month guarantee, wherever you are in Greater London.

Can I do it myself?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Surface by surface

Gutter joints

Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.

Garage door frames

Resealing a garage door frame keeps rain and draughts out.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours, depending on the number of joints and the access. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First, we find the drip and check the gutter isn’t cracked or sagging.
  2. Old sealant and dirt are removed from the joint.
  3. The area is dried so the sealant can bond.
  4. Gutter or exterior sealant is applied and finished.
  5. We look along the gutter and clear debris around the joints.

Before we arrive

  • Tell us about any water getting in
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any parking rules near the property

Walls and rooflines in Catford

Historic houses like Eltham Palace (about 2.8 miles east) are a reminder that the area around Catford 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 check who is responsible for the outside before booking.

If you look after a building such as Holy Cross Catholic Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Catford Bridge station, leaking gutter joints on a rental are best caught before they stain the walls.
