How we quote for gutter sealing
For a quick quote, just ask. The main things that affect it are:
- Whether there’s mould to deal with
- How easy the joints are to reach
- The old material and how stubborn it is
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- Whether it has been sealed before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Gutter sealing for homes and businesses in Brentford End
A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it using a gutter sealant. If the gutter itself has failed, we say so. If you are dealing with fascia boards with gaps between them and rain getting in around a garage door, we can help, whatever the surface.
Modern London flats rely on sealed movement joints and cladding joints. 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Walls and rooflines in Brentford End
Historic houses like Syon House (about 0.5 miles south-east) are a reminder that the area around Brentford End has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
In the older streets around Church of St Lawrence, the joints between older walls, newer extensions and the roofline need a sealant that can move. As a London address, Brentford End can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

How to look after the new joints
So the new joints stay in good condition:
- Rest ladders on the wall, not the gutter
- Check that water runs out of the downpipes
- Look along the fascias for open joints
- Get a dropping gutter looked at quickly
A sagging gutter needs its brackets checked. If it drops, the joints will open.
A drip from a gutter joint will not stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.

Signs you need gutter sealing in Brentford End
Leaves and moss hold water in the gutter. Standing water finds the weakest joint and leaks out.
If you can see any of these, it’s time to have the joints looked at:
- End caps that drip every time it rains
- Quick sealant fixes on gutters that didn’t last
- Gaps along fascia and soffit joints
- Trim joints where the sealant has failed
For site and facilities teams at buildings such as The Green School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Is the old sealant removed completely?
- Are they insured?
- How the surfaces are prepared before sealing
- How long to leave it before use
