Trusted gutter sealing in Greengate

What happens on the day

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take an hour or two for a few joints, longer for a full run. 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 trace the drip and check the gutter isn’t damaged.
  2. The old sealant and dirt are cleaned out of the joint.
  3. The joint is dried before sealing.
  4. We seal the joint with a sealant made for gutters.
  5. The gutter is checked and debris around the joints cleared.

How to prepare

  • Mention any parking rules near the property
  • For business premises, tell us about site rules or sign-in
  • Keep pets and children clear of the area while we work

How we handle gutter sealing in Greengate

For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on uPVC fascias, gutter end caps and garage door frames, and people most often call us about trim joints where the sealant has failed and garage door frames letting rain in.

Modern London flats rely on sealed movement joints and cladding joints. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.

Every job is covered by our one-year guarantee, wherever you are in Greater London.

Leave it or put it right?

If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and point you to the right trade if needed. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What you get with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • Colour picked to suit the job
  • Old sealant always removed completely
  • More than 20 years in sealant work

Take a look at how sealant jobs are priced and customer reviews.

What we cannot put right

Some problems need a builder, plumber or other trade rather than us:

  • Water backing up from a blocked pipe
  • Brackets that have snapped or loosened
  • Boards that have decayed or split

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.

What we seal

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

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Make sure downpipes aren’t blocked
  • Don’t lean ladders against the gutter itself
  • Sort out a dripping joint early
  • Watch the wall under the gutters for staining

Have a look at the gutter during a downpour now and then. It’s the easiest time to see a leak.

The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Do you need gutter sealing in Greengate?

Sagging sections pull joints apart. Resealing a sagging joint will not last, so the gutter needs refixing first.

Keep an eye out for any of the following:

  • Open joints in fascias and soffits
  • Water running down the wall below the gutter
  • Internal damp traced to a gutter joint
  • Dripping gutter ends

For landlords with property near West Ham station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Gutter sealing in Greengate: local notes

The South East is one of 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 Eastbury Manor House (about 3.1 miles east) are a reminder that the area around Greengate 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.

For site and facilities teams at buildings such as Southern Road Primary School, its movement joints, gutters and trims need looking after like any other building’s. As a London address, Greengate can be tricky for parking: let us know about parking bays, permits or a driveway.
