When to call us in Putney Vale
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.
The problems people usually mention when they call include:
- Damp on an inside wall under a dripping gutter
- Leaking gutter joints and stop ends
- Wet patches on the wall under a gutter joint
- Cracked sealant along roofline trims
In the older streets around St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Gutter sealing in Putney Vale
We do not replace gutters, fascias or roofs. Sealant fixes joints and it can’t mend broken brackets, split sections or blocked downpipes. If you have old sealant on roofline trims that has split and stop ends leaking at the end of a run, we can put it right, whatever the surface.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. For a flat in Putney Vale, check the lease for who looks after the outside.
There’s a 12-month guarantee on every job, whatever its size.

Why act early in Putney Vale
A new garage door is not needed for a leaking frame. Resealing the frame joint is often enough. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It usually takes an hour or two for a few joints, longer for a full run. For a job in Putney Vale, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First we trace the drip and check the gutter is not damaged.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Before we arrive

Advice
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Problems with the roof covering
- A gutter length that has split
- Water backing up from a blocked pipe
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

As a London address, Putney Vale can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like Hall School Wimbledon? Then larger buildings have long runs of movement joint that eventually need resealing.

Do you clean gutters?
The joints we seal are cleaned out and any debris nearby is cleared. A full gutter clean is a separate service.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Do you install new fascias or gutters?

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
