Colliers Wood Gutter Sealing
Gutter sealing in Colliers Wood from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Drips from gutter joints and end caps
- Damp on an inside wall under a dripping gutter
- Trim joints where the sealant has failed
Why deal with it now?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Colliers Wood, the repair is bigger than a sealant job.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

Gutter sealing for homes and businesses in Colliers Wood
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. We work on gutter joints, soffit joints and uPVC fascias, and the jobs we see most are water running down the wall below the gutter and stop ends leaking at the end of a run.
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.
All our work is covered by our 12-month guarantee, wherever you are in Greater London.

Common questions in Colliers Wood
Can parking be tricky for a visit in Colliers Wood?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
I let a flat near Tooting station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How much does gutter sealing cost in Colliers Wood?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Will you clear out my gutters?
We clear debris around the joints we are sealing. Full gutter cleaning is a separate job.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
How long does the job take?
Typically it takes an hour or two for a few joints, longer for a full run. Bigger jobs take longer, and we will say how long yours will take.
Is sealing fascia joints something you do?
Yes. Open joints along uPVC fascias and soffits can be sealed in a matching colour.
When it is not the sealant
We will not take on work that won’t last, so these are the limits:
- Water backing up from a blocked pipe
- Sagging gutters or broken brackets
- Problems with the roof covering
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Outside joints around Colliers Wood
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
If you look after a building such as Sellincourt Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Tooting station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:

- Keep the gutters clear of debris
Leave the new sealant to cure as we advise and avoid disturbing it.

Mention any building rules, key holders or managing agents when you book.

- Old sealant and dirt are removed from the joint.
- We make sure the joint is dry before sealing.
- An exterior or gutter sealant is applied to the joint.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
