How we handle gutter sealing in Woolwich
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we’ll tell you. We work on garage door frames, uPVC fascias and roofline trims, and people most often call us about open joints in fascias and soffits and internal damp traced to a gutter joint.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Woolwich, tell us how high the joints are and how to reach the back of the building.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Walls and rooflines in Woolwich
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
Woolwich is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near Woolwich Dockyard station, leaking gutter joints on a rental are best caught before they stain the walls.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep downpipes clear
- Keep an eye out for wet patches below a joint
- Get a dropping gutter looked at quickly
- Check fascia and soffit joints for gaps
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
A leaking garage frame lets water reach stored items. A reseal sorts it while the frame is sound.
Why deal with it now?
Sealant won’t clear a blocked downpipe. We check the cause first and tell you if something else is needed. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Woolwich, the repair is bigger than a sealant job.
Combining jobs into one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Do you need gutter sealing in Woolwich?
Sealant on fascias and trims weathers like any outdoor joint. It goes hard, cracks and pulls away after some years.
Any of these means the joints need attention:
- Wet patches on the wall under a gutter joint
- Old gutter sealant that has let go
- Damp on an inside wall under a dripping gutter
- Cracked sealant along roofline trims
Schools such as Mulgrave Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

How the visit works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours, depending on the number of joints and the access, depending on how much there is to do. In Woolwich, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
How to prepare
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
