Gutter sealing for homes and businesses in Eastcote
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where possible. We work on gutter joints, gutter end caps and soffit joints, and the jobs we see most are wet patches on the wall under a gutter joint and gaps along fascia and soffit joints.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Eastcote, joints up high may need ladders or other access, which is worth talking through when you book.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What affects the cost of gutter sealing
There’s no set price list. The quote depends on:
- When we can work, for business premises
- The product the joint needs
- The old material and how stubborn it is
- Any mould that needs treating
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- A few photos by email, if you can
- Where the job is, and your postcode
- The rough size of the job
- The type of property
If you’re in Eastcote and need gutter sealing, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
Gutter sealing in Eastcote: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
For an older house near a landmark such as St Lawrence, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Cannon Lane Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Headstone Lane station, leaking gutter joints on a rental are best caught before they stain the walls.

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 chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Surface by surface
Soffit joints
Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.
uPVC fascias
Fascia board joints can open up. We seal them neatly with a matching sealant where possible.
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It usually takes anything from an hour or two to a few hours. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- We clean out the joint and take out the old sealant.
- We make sure the joint is dry before sealing.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we are there.
Getting ready for the visit
- Mention any tricky access
- Clear the area around the work
- Mention if the joints have been sealed before

What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you install new fascias or gutters?
That’s not something we do. We seal joints and replacement is a job for an installer.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Looking after it afterwards
To keep the joints looking good and working properly:
- Do not leave a sagging gutter
- Watch the wall under the gutters for staining
- Clear leaves and moss from the gutters
- Glance at the soffit joints now and then
Clear the gutters once or twice a year, so water drains away past the joints. Water left in a gutter tests every joint.
Early sealing limits how much water hits the wall. We will let you know if the gutter needs more than sealant.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Blocked downpipes
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- A gutter length that has split
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
