Gutter sealing in Coldblow, done properly
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. We are often asked to deal with gaps along fascia and soffit joints and cracked sealant along roofline trims, across soffit joints, garage door frames and gutter joints.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Coldblow, joints up high may need ladders or other access, which is worth talking through when you book.
Your job is guaranteed for a year, as with all our work.

Coldblow questions
Is Coldblow in your area for gutter sealing?
Yes. We work across London and the South East, and Coldblow is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Can parking be tricky for a visit in Coldblow?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
What about gutters on a second or third storey?
That depends on the building. Tell us the height and what’s around the gutter and we will confirm what’s needed.
How do I get a quote for gutter sealing in Coldblow?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Is gutter cleaning part of the job?
We clean the joints we are sealing and clear debris we find nearby. A full gutter clean is a separate service.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Look at the gutters while it’s raining
- Clean out the gutters once or twice a year
- Rest ladders on the wall, not the gutter
- Make sure downpipes aren’t blocked
Keep downpipes clear so the gutter can drain. A blocked pipe backs water up to the joints.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.
How the job changes by surface
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily with a matching sealant where possible.
Roofline trims
Trim joints are cut out and resealed suited to the material.
Coldblow buildings and the weather
In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. 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.
If you live in an older home near Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Maypole Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Bexley station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
Coldblow is about 3 miles east of Sidcup, in Greater London. From the centre of Coldblow to the outskirts, gutter sealing is available for homes and businesses alike, from flats and houses to offices and hotels. Coldblow is one of 764 places in Greater London we cover for gutter sealing. There’s also a page for London, roughly 12 miles from Coldblow.
Work in DA5 is quoted and booked the same way as anywhere else. If you need gutter sealing at a property on St Mary's Road, Dartford Road and Wansunt Road or anywhere close by, our applicators can take on the job. If you’re just outside Coldblow, we cover Joyden's Wood (1 mile south-east), Bowmans (1 mile east), North Cray (1 mile south-west), Crayford (1 mile north-east) and Wilmington (1 mile south-east). Larger places within reach include London (12 miles west), City of Westminster (15 miles west), Marylebone (14 miles north-west), St Pancras (14 miles north-west), Shoreditch (12 miles north-west) and Walthamstow (13 miles north-west).
Around Coldblow
We work in homes and buildings around The Old Wick pub, St Columba's Catholic Boys' School and Braeburn Park and the streets around them. For rail, the closest station is Bexley station, roughly 0.6 miles west. Nearby you will also find Stone Castle (5 miles east) and Bexley Museum (0.7 miles north). Not far away are Wansunt Pit and Summer Hill.
What happens if it’s left?
If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and point you to the right trade if needed. 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 Coldblow, the repair is bigger than the sealant job would have been.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work 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 Coldblow. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- The area is dried so the sealant can bond.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we are there.
Getting ready for the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

Advice
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Blocked downpipes
- Guttering that needs replacing
- Rotten or damaged fascia boards
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
