How we handle gutter sealing in Gunnersbury
We work across Gunnersbury on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we’ll confirm what access is needed. Typical jobs include old gutter sealant that has let go and leaking gutter joints and stop ends, across garage door frames, gutter joints and roofline trims.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Gunnersbury, joints up high may need ladders or other access, which is worth talking through when you book.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clear leaves and moss from the gutters
- Deal with a drip before winter
- Don’t leave a sagging gutter
- Do not lean ladders against the gutter itself
Check the joints after heavy rain. It’s the easiest time to see a leak.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.

What the job involves on each surface
Soffit joints
Soffit joints are sealed in a colour to suit.
Roofline trims
We reseal trim joints with an exterior sealant.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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.
Your questions about gutter sealing in Gunnersbury
Do you cover Gunnersbury for gutter sealing?
Yes. We work across London and the South East, and Gunnersbury is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
I let a flat near Gunnersbury station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Can you seal fascia and soffit joints?
Yes, often alongside gutter joints. Each joint is cleaned and sealed.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Walls and rooflines in Gunnersbury
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Gunnersbury Park (about 0.7 miles north-west) are a reminder that the area around Gunnersbury has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as St Michael's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Gunnersbury station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

What we’re called out for in Gunnersbury
Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
Any of these means the joints need attention:
- Water dripping where gutter sections meet
- Wet patches on the wall under a gutter joint
- Gaps along fascia and soffit joints
- Garage door frames letting rain in
If you look after a building such as Strand-on-the-Green Junior School, larger buildings have long runs of movement joint that eventually need resealing.

- The length of the guarantee

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes a few hours, depending on the number of joints and the access. In Gunnersbury, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- We look along the gutter and clear debris around the joints.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Why act early in Gunnersbury
A new garage door is not needed for a leaking frame. Resealing the frame joint is often enough. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Gunnersbury, the repair is bigger than the sealant job would have been.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.
