About our gutter sealing in Gillette Corner
A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We work on gutter joints, uPVC fascias and gutter end caps, and the jobs we see most are fascia boards with gaps between them and end caps that drip every time it rains.
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, and both kinds of building are found across London.
All our work is covered by a one-year guarantee, wherever you are in Greater London.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Aftercare tips
So the new joints stay in good condition:
- Keep the gutters clear of debris
- Get a dropping gutter looked at quickly
- Deal with a drip before winter
- Look at the gutters while it’s raining
Keep downpipes clear so the gutter can drain. A blocked pipe backs water up to the joints.
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.
Gutter sealing in Gillette Corner: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
For landlords with property near Syon Lane station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. In the older streets around St Mary's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Advice
What we are called out for in Gillette Corner
Gutter joints rely on seals that age. Temperature changes make gutters move, and old seals crack or slip.
The most common problems we see are:
- Rain getting in around a garage door
- Quick sealant fixes on gutters that didn’t last
- Damp patches inside below a leaking gutter
- Fascia boards with gaps between them
Schools such as Marlborough Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- What insurance they hold
- What the quote includes, VAT included or not
- Is the old sealant removed completely?
- How long to leave it before use
When something else is needed
In fairness, some problems need a different trade:
- Fascias that need replacing
- A gutter length that has split
- Downpipes that are blocked or broken
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.
What we seal
- uPVC fascias
- Soffit joints
- Roofline trims
- Gutter joints
- Garage door frames
- Gutter end caps
Landlords, agents and businesses in Gillette Corner
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
What happens if it’s left?
Sealant won’t clear a blocked downpipe. We look at what’s really happening and point you to the right trade if needed. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Gillette Corner, the repair is bigger than a sealant job.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
