Gutter sealing for homes and businesses in Crossness
A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. If you have leaking gutter joints and stop ends and streaks down the brickwork from a leaking joint, we can put it right.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. In a converted house in Crossness, it’s worth checking who is responsible for the outside before booking.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

How to look after the new joints
So the new joints stay in good condition:
- Look at the gutters while it’s raining
- Clean out the gutters once or twice a year
- Glance at the soffit joints now and then
- Check that water runs out of the downpipes
Check the joints after heavy rain. Drips are easiest to spot while it’s raining.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.

Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.

It depends on the size of the job, but most jobs take a few hours, depending on the number of joints and the access. We will tell you when we quote.

We work from Crawley. We cover Crossness and the rest of Greater London.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
When to call us in Crossness
Sealant on fascias and trims weathers like any outdoor joint. It goes hard, cracks and pulls away over time.
It’s worth asking for a quote if you see:
- Water running down the wall below the gutter
- Stop ends leaking at the end of a run
- Trim joints where the sealant has failed
- Old gutter sealant that has let go
Rented homes near Abbey Wood station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
What your quote should include
- Which sealant they’ll use, and why
- What preparation is included
- Whether they seal over old material or remove it
- When the joint can take water or movement
What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes an hour or two for a few joints, longer for a full run. For a job in Crossness, 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.
- First we trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Advice
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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.
Surface by surface
Gutter joints
Joints between gutter lengths are the most common leak point. They’re cleaned out, dried and resealed.
Gutter end caps
End caps are resealed where they meet the gutter once clean and dry.
Outside joints around Crossness
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Rainham Hall (about 2.8 miles north-east) nearby, there’s older building stock in the area around Crossness as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Crossness is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as St John Fisher Catholic Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
