Gutter sealing in Greenhill
Garage door frames let rain in when the sealant around them fails. We cut out the old sealant and reseal the frame using a sealant made for outdoor use. We work on gutter end caps, gutter joints and uPVC fascias, and common reasons people get in touch are cracked sealant along roofline trims and old gutter sealant that has let go.
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 Greenhill, it’s worth checking who is responsible for the outside before booking.
Your job is guaranteed for a year, as with all our work.

What we are called out for in Greenhill
Sealant laid on a wet or dirty joint fails early. Rushed repairs often don’t last long.
Common reasons people contact us include:
- Internal damp traced to a gutter joint
- Earlier gutter repairs that have peeled off
- End caps that drip every time it rains
- Rain getting in around a garage door
In the older streets around Rosslyn Hill Unitarian Chapel, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing
- What the cure time is
- Are they insured?

The process
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes an hour or two for a few joints, longer for a full run for a typical job. For a job in Greenhill, parking and access are the things to plan: 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 won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we’re there.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Landlords and letting agents in Greenhill can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
What affects the cost of gutter sealing
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- Access and height
- Which sealant suits the joint
- The number and length of the joints
Doing several joints on one visit is normally more efficient than separate visits. We will send you a clear quote for the lot.
What we need to know
When you contact us, it’s useful to know:
- Pictures of the joints, sent by email
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
To get a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before work begins.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Don’t lean ladders against the gutter itself
- Keep an eye out for wet patches below a joint
- Have sagging gutters refixed early
- Look along the fascias for open joints
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.

What else we do in Greenhill
Outside joints around Greenhill
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as 2 Willow Road (about 0.3 miles north-east) nearby, there’s older building stock in the area around Greenhill 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.
Managing a site like The Royal School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Greenhill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Why act early in Greenhill
You do not need new fascias just because the joints have opened. A neat seal closes the gaps as long as the boards are in good condition. 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.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
What you get with us
- More than 20 years in sealant work
- Approved under the ARBOMaster scheme

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
