Gutter sealing in Heron Quays
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs if the gutter is not damaged. Common call-outs are for rain getting in around a garage door and damp patches inside below a leaking gutter, across soffit joints, roofline trims and uPVC fascias.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Heron Quays, tell us how high the joints are and how to reach the back of the building.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

FAQs for Heron Quays
Do you work for landlords with property near Canary Wharf station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is parking a problem for a job in Heron Quays?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you cover Heron Quays?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Heron Quays.
Where is Mr Mastic based?
We work from Crawley. We cover Heron Quays and the rest of Greater London, along with the rest of our area.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Is gutter cleaning part of the job?
Only around the joints we seal because the joint must be clean. A full gutter clean is a separate job.
Is it possible to stop a gutter joint dripping with sealant?
In many cases, yes. A clean, dry joint resealed with gutter sealant usually stops the drip. If the section is split or warped, it needs replacing.
How much does gutter sealing cost in Heron Quays?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

Walls and rooflines in Heron Quays
With historic houses such as Queen's House (about 1.7 miles south-east) nearby, there’s older building stock in the area around Heron Quays as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
In the older streets around St Peter's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Canary Wharf station? Then leaking gutter joints on a rental are best caught before they stain the walls.

Why deal with it now?
Sealant will not clear a blocked downpipe. We check the cause first and tell you if something else is needed. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What you get with us
- Approved under the ARBOMaster scheme
- A 12-month guarantee on all work

- Anti-fungal silicone where joints get wet
See our cost guide or our reviews.
Looking after it afterwards
Aftercare is simple:
- Check the gutters during heavy rain
- Do not lean ladders against the gutter itself
- Make sure downpipes are not blocked
- Glance at the soffit joints now and then
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
Common problems we fix in Heron Quays
Gutter joints rely on seals that age. Temperature changes make gutters move, and old seals crack or slip.
Any of these means the joints need attention:
- Leaking gutter joints and stop ends
- Fascia boards with gaps between them
- Quick sealant fixes on gutters that didn’t last
- End caps that drip every time it rains
As a London address, Heron Quays can be tricky for parking: let us know about parking bays, permits or a driveway.
