Gutter Sealing in Wimbledon Chase
Gutter sealing in Wimbledon Chase from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Quick sealant fixes on gutters that didn’t last
- Leaking gutter joints and stop ends
- Damp on an inside wall under a dripping gutter
How to look after the new joints
To keep the joints looking good and working properly:
- Watch the wall under the gutters for staining
- Make sure downpipes are not blocked
- Do not lean ladders against the gutter itself
- Have sagging gutters refixed early
Make sure downpipes are not blocked, so water can get away. Blockages push water back along the gutter.
A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.
Gutter sealing for homes and businesses in Wimbledon Chase
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs, as long as the gutter is sound. Common call-outs are for rain getting in around a garage door and end caps that drip every time it rains, on soffit joints, roofline trims and garage door frames.
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.
Each job carries a 12-month guarantee, large or small.

What affects the cost of gutter sealing
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Working hours on commercial sites
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What we need to know
When you call or email, it’s useful to know:
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Roughly how big the job is
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
Wimbledon Chase: your questions answered
Is parking a problem for a job in Wimbledon Chase?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Wimbledon Chase station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can a leaking gutter joint be sealed?
Normally, if the gutter is sound. We clean and dry the joint before sealing so the sealant bonds.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Why it’s worth doing now in Wimbledon Chase
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job before the damage spreads. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Wimbledon Chase, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Walls and rooflines in Wimbledon Chase
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. With historic houses such as Southside House (about 1 mile north-west) nearby, there’s older building stock in the area around Wimbledon Chase as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Wimbledon Chase is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Wimbledon Chase Primary School, larger buildings have long runs of movement joint that eventually need resealing.
