About our gutter sealing in Colney Street
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. If you have gaps along fascia and soffit joints and water dripping where gutter sections meet, we can help, on soffit joints, garage door frames and uPVC fascias alike.
Older homes in small places like Colney Street may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Colney Street questions
I let a flat near How Wood station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Colney Street in your area for gutter sealing?
Yes. Our work covers London and the South East, and Colney Street is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you work on high-level gutters?
It depends on the access. Let us know the height and the ground below when you phone 0345 464 0079 or email us.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
What do you need from me for a quote?
Let us know what needs doing and where. We will ask anything else we need to know.
What happens if it’s left?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. Older cottages and farmhouses around Colney Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we are called out for in Colney Street
Leaves and moss hold water in the gutter. Standing water finds the weakest joint and drips through.
Signs it’s time to call us include:
- End caps that drip every time it rains
- Open joints in fascias and soffits
- Water running down the wall below the gutter
- Old sealant on roofline trims that has split
For site and facilities teams at buildings such as Park Street Church of England Voluntary Aided Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Gutter sealing in Colney Street: local notes
Historic houses like High Elms Manor (about 2.9 miles west) are a reminder that the area around Colney Street has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near How Wood station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. In the older streets around Church of the Holy Trinity, older walls, gutters and the joints where extensions meet them need a flexible sealant.
