About our gutter sealing in Custom House
We seal leaking gutter joints, end caps, fascia and soffit joints, along with roofline trims and garage door frames. It’s joint work, not replacing the gutter. We work on gutter joints, uPVC fascias and garage door frames, and common reasons people get in touch are internal damp traced to a gutter joint and trim joints where the sealant has failed.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Custom House, tell us how high the joints are and how to reach the back of the building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Gutter sealing in Custom House: local notes
Historic houses like Queen's House (about 2.3 miles south-west) are a reminder that the area around Custom House 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Matthew's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. As a London address, Custom House can be tricky for parking: let us know about parking bays, permits or a driveway.

Common questions in Custom House
Is Custom House in your area for gutter sealing?
Yes, Custom House is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can parking be tricky for a visit in Custom House?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
What about gutters on a second or third storey?
Low-level work is easiest. For anything higher, we will confirm what access is needed once we know more.
Will sealant fix a dripping gutter joint?
Normally, if the gutter is sound. We clean and dry the joint before sealing so the sealant bonds.
Are you insured?
Yes. We’re fully insured.
How long does gutter sealing take?
Typically it takes a few hours, depending on the number of joints and the access. Bigger jobs take longer.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Leave it or put it right?
A dripping gutter joint keeps wetting the same patch of wall. 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 once it shows in Custom House, the repair is bigger than a sealant job.
Doing several joints on one visit generally makes better use of the time than several visits. We will send you a clear quote for the lot.

What we are called out for in Custom House
End caps get knocked or pushed by water. If the seal fails, water escapes at the end and runs down the wall.
The problems people normally mention when they call include:
- Streaks down the brickwork from a leaking joint
- Cracked sealant along roofline trims
- Open joints in fascias and soffits
- Damp on an inside wall under a dripping gutter
Managing a site like St Joachim's Catholic Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- Who turns up on the day
- What product goes in the joint
- How the surfaces are prepared before sealing
- Whether you can choose the colour
Different surfaces, different methods
Gutter joints
A dripping joint does not always mean a failed gutter. Sealing the joint often stops it.
uPVC fascias
Fascia board joints can open up. We seal them neatly with a matching sealant where possible.
