About our gutter sealing in Stonebridge Park
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs if the gutter is not damaged. If you have internal damp traced to a gutter joint and drips from gutter joints and end caps, we can help, whatever the surface.
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.
Your job is guaranteed for a year, as with all our work.

What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on the number of joints and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Stonebridge Park. A visitor permit or a nearby bay makes the visit run more smoothly.

- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Before we arrive

How the job changes by surface
Garage door frames
Garage door frames let rain in when their sealant fails. It’s removed and renewed.
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Stonebridge Park buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
If you look after a building such as Our Lady of Lourdes RC Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Stonebridge Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Homes close to St Michael the Archangel include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

When something else is needed
New sealant can’t fix everything, and we will tell you before we start. Sealant won’t put right:
- Problems with the roof covering
- Water backing up from a blocked pipe
- Brackets that have snapped or loosened
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Surfaces we seal
- uPVC fascias
- Soffit joints
- Garage door frames
- Gutter joints
- Gutter end caps
- Roofline trims
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Sort out a dripping joint early
- Don’t leave a sagging gutter
- Look along the fascias for open joints
- Do not lean ladders against the gutter itself
Check the joints after heavy rain. It’s the easiest time to see a leak.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.
What happens if it’s left?
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Proper preparation is the difference. 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 affects the quote in Stonebridge Park
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether the work is at height
- How many rooms, windows or areas are involved
- The type of sealant required
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear price before work begins.

When you contact us, it’s useful to know:

- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
