Gutter sealing in Orpington, done properly
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed with an exterior sealant. We work on soffit joints, uPVC fascias and roofline trims, and the jobs we see most are drips from gutter joints and end caps and fascia boards with gaps between them.
Modern London flats rely on sealed movement joints and cladding joints. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.
All of our work is guaranteed for twelve months, in Orpington and everywhere else we cover.

Why act early in Orpington
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Orpington, the repair is bigger than the sealant job would have been.

Do you work for landlords with property near St Mary Cray 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’ll give you a fixed price before work begins.
Can you match the sealant colour?

What information do you need?
Tell us what needs doing and where. If we need more, we’ll ask.
How long does the job take?
It depends on the size of the job, but as a guide it takes an hour or two for a few joints, longer for a full run. We will tell you when we quote.
Is gutter cleaning part of the job?
Only around the joints we seal, so the sealant can bond. Cleaning the whole run is a separate job.
Is sealing fascia joints something you do?
Yes. Open joints along uPVC fascias and soffits can be sealed in a matching colour.
Can you fit new guttering?
Replacement is not our trade. We’ll tell you if the gutter needs replacing.

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes an hour or two for a few joints, longer for a full run, including the tidy-up.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check the gutters during heavy rain
- Clear leaves and moss from the gutters
- Get leaks sealed before the wet months
- Watch the wall under the gutters for staining
Keep downpipes clear so the gutter can drain. A blocked pipe backs water up to the joints.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches.
Walls and rooflines in Orpington
In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. With historic houses such as Bromley Palace (about 3.8 miles west) nearby, there’s older building stock in the area around Orpington 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.
As a London address, Orpington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St Andrew's, an extension built onto an older house moves differently, and the joint between them takes the strain.
