Gutter sealing in Chelsea Harbour, done properly
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on garage door frames, uPVC fascias and gutter end caps, and the jobs we see most are drips from gutter joints and end caps and garage door frames letting rain in.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. In a converted house in Chelsea Harbour, 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’ll sort it.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take an hour or two for a few joints, longer for a full run. In a London area like Chelsea Harbour, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant will not bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
Preparing for the visit
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit

Advice
Why act early in Chelsea Harbour
Replacing guttering is a much bigger job than sealing joints. Where the gutter is in good order and only a joint leaks, resealing is the sensible fix. If it’s broken or sagging, a gutter installer needs to look. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- Any old sealant cut out fully, not covered over

Honest limits
It helps to know what we can’t do:

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
Outside joints around Chelsea Harbour
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Carlyle's House (about 0.8 miles north-east) nearby, there’s older building stock in the area around Chelsea Harbour as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Chelsea Harbour is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. In the older streets around St Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How to look after the new joints
To keep the joints looking good and working properly:
- Rest ladders on the wall, not the gutter
- Watch the wall under the gutters for staining
- Check that water runs out of the downpipes
- Clean out the gutters once or twice a year
Check the joints after heavy rain. It’s the easiest time to see a leak.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches inside.
FAQs for Chelsea Harbour
Can you do gutter sealing in Chelsea Harbour?
Yes, Chelsea Harbour is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Imperial Wharf station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
Is gutter cleaning part of the job?
Only around the joints we seal because the joint must be clean. Cleaning the whole run is a separate job.
Do you install new fascias or gutters?
No. We seal joints and replacement is a job for an installer.
Where do you work from?
We work from Crawley. Our applicators cover Chelsea Harbour.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you need gutter sealing in Chelsea Harbour?
Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up, which is why we look before we seal.
Common reasons people contact us are:
- Cracked sealant along roofline trims
- Old gutter sealant that has let go
- Garage door frames letting rain in
- Water running down the wall below the gutter
If you look after a building such as Chelsea Academy, larger buildings have long runs of movement joint that eventually need resealing.
