Do you need gutter sealing in Canonbury?
Debris in the gutter keeps water sitting at the joints. Standing water finds the weakest joint and drips through.
If you can see any of these, it’s time to have the joints looked at:
- Gaps along fascia and soffit joints
- Damp patches inside below a leaking gutter
- Dripping gutter ends
- Wet patches on the wall under a gutter joint
In the older streets around St Paul's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Whether VAT is included
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
Gutter sealing for homes and businesses in Canonbury
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs if the gutter is not damaged. If you have water dripping where gutter sections meet and wet patches on the wall under a gutter joint, we can help, whatever the surface.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Canonbury, joints up high may need ladders or other access, which is worth talking through when you book.
Your job is guaranteed for a year, as with all our work.

Walls and rooflines in Canonbury
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 Sutton House (about 1.7 miles east) nearby, there’s older building stock in the area around Canonbury 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.

- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.

Advice
Leave it or put it right?
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Proper preparation is the difference. In a flat in Canonbury, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Why book with us

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Look for streaks or damp on the wall below gutters
- Get leaks sealed before the wet months
- Look along the fascias for open joints
- Rest ladders on the wall, not the gutter
Clear the gutters once or twice a year so water doesn’t sit on the joints. Water left in a gutter tests every joint.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.
