Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
How we handle gutter sealing in Islington
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first, then dry the joint before sealing. Typical jobs include stop ends leaking at the end of a run and internal damp traced to a gutter joint, on soffit joints, gutter end caps and gutter joints.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
A one-year guarantee comes as standard.

What affects the cost of gutter sealing
The quote reflects the job in front of us. We look at:
- The number of rooms or windows
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- If someone has resealed it before

Walls and rooflines in Islington
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. Historic houses like Dr Johnson's House (about 1.6 miles south) are a reminder that the area around Islington has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Essex Road station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Homes close to St Mary's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes anything from an hour or two to a few hours. In Islington, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- The joints are dried.
- The sealant is applied and finished.
- We check our work before we leave.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep an eye out for wet patches below a joint
- Get a dropping gutter looked at quickly
- Clean out the gutters once or twice a year
- Look along the fascias for open joints
If a gutter starts to sag, get the brackets looked at. If it drops, the joints will open.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.
