Gutter Sealing in Widmore
Gutter and fascia joints in Widmore need attention? We cut out the old, prepare the joints and apply the right sealant.

Why it’s worth doing now in Widmore
If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and tell you if something else is needed. 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. Dealing with it early is far simpler.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

About our gutter sealing in Widmore
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough, as long as the gutter is sound. We work on soffit joints, gutter joints and gutter end caps, and people most often call us about garage door frames letting rain in and earlier gutter repairs that have peeled off.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Widmore, it’s worth checking who is responsible for the outside before booking.
All our work is covered by a one-year guarantee, wherever you are in Greater London.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on the number of joints and the access. In a London area like Widmore, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- 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
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
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.
What gutter sealing looks like in Widmore
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. With historic houses such as Bromley Palace (about 1.1 miles west) nearby, there’s older building stock in the area around Widmore as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Bickley station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls. Managing a site like Bullers Wood School for Boys? Then larger buildings have long runs of movement joint that eventually need resealing.

Signs you need gutter sealing in Widmore
When a gutter sags, its joints open. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
The problems people usually mention when they call include:
- Drips from gutter joints and end caps
- Old gutter sealant that has let go
- Damp patches inside below a leaking gutter
- Cracked sealant along roofline trims
Homes close to Church of St George include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How to look after the new joints
Looking after new joints is easy:
- Clean out the gutters once or twice a year
- Check that water runs out of the downpipes
- Look for streaks or damp on the wall below gutters
- Get a dropping gutter looked at quickly
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp.

Can parking be tricky for a visit in Widmore?
Parking in Widmore, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
