North Wembley Gutter Sealing
Gutter and fascia joints in North Wembley need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

About our gutter sealing in North Wembley
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where one is available. We’re often asked to deal with fascia boards with gaps between them and dripping gutter ends, on garage door frames, gutter joints and soffit joints.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
Big or small, it’s backed by our 12-month guarantee.

The process
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from an hour or two to a few hours, and we tell you how long to leave it before we go. In North Wembley, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First we trace the drip and check the gutter isn’t damaged.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Mention any tricky access

Advice
Outside joints around North Wembley
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 Northolt Manor (about 2.9 miles west) nearby, there’s older building stock in the area around North Wembley 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.
If you look after a building such as Park Lane Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St John include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. As a London address, North Wembley can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Should I try it myself first?
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 doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Honest limits
We will not take on work that will not last, so these are the limits:
- Cracked, split or warped gutter sections
- Fascias that need replacing
- Downpipes that are blocked or broken
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Surface by surface
Roofline trims
Roofline trims rely on sealant at their joints. Split sealant lets water in.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
How to look after the new joints
After the cure time, these simple habits help:
- Keep downpipes clear
- Check the gutters during heavy rain
- Have sagging gutters refixed early
- Clear leaves and moss from the gutters
Check the joints after heavy rain now and then. Drips are easiest to spot while it’s raining.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.

Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Is sealant enough for a gutter that has dropped?
