Gutter sealing in Harrow Weald

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Gutter sealing in Harrow Weald

Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s all about the joints rather than new guttering. If you have water running down the wall below the gutter and rain getting in around a garage door, we can help, on garage door frames, roofline trims and soffit joints alike.

London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Harrow Weald, it’s worth checking who is responsible for the outside before booking.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Glance at the soffit joints now and then
  • Make sure downpipes aren’t blocked
  • Keep ladders off the guttering
  • Get a dropping gutter looked at quickly

Keep downpipes clear so the gutter can drain. Blockages push water back along the gutter.

Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.

It depends on the size of the job, but as a guide it takes a few hours, depending on the number of joints and the access. We will tell you when we quote.

Will sealant fix a dripping gutter joint?
