Gutter sealing for homes and businesses in Chinatown
Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s all about the joints rather than new guttering. Common call-outs are for old sealant on roofline trims that has split and earlier gutter repairs that have peeled off, across soffit joints, gutter end caps and garage door frames.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Chinatown, tell us how high the joints are and how to reach the back of the building.
All our work comes with a 12-month guarantee.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Common questions in Chinatown
Is parking an issue for gutter sealing in Chinatown?
Parking in Chinatown, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you cover Chinatown for gutter sealing?
Yes. Our work covers London and the South East, and Chinatown is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
What guarantee comes with the job?
Our 12-month guarantee covers every job, gutter and fascia work included.
Can you seal fascia and soffit joints?
We do. Our work is the joints and we will let you know if a board has failed.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What does gutter sealing cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Chinatown buildings and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
Rented homes near Tottenham Court Road station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. As a London address, Chinatown can be tricky for parking: let us know about parking bays, permits or a driveway.
Chinatown is about 1 mile east of City of Westminster, in Greater London. Anywhere in W1F, our applicators can take on gutter sealing. Our Greater London coverage runs to 764 places, Chinatown among them.
Work in W1F, W1D and W1T works the same way as everywhere else we cover. We cover properties on Duck Lane, Drury Lane and Bruton Lane. You will find Chinatown on the A4 and A301, which makes it straightforward to reach. Nearby, we also carry out gutter sealing in Soho (1 mile north), St James's (1 mile south), West End (1 mile north-east), Seven Dials (1 mile north-east) and St Giles (1 mile north-east). Larger places within reach include Kensington (3 miles west), Shoreditch (3 miles north-east), Walthamstow (7 miles north-east), Hoxton (3 miles north-east), Whitechapel (3 miles east) and Hampstead (4 miles north-west).
What’s near Chinatown
In Chinatown, that means homes and buildings near LITE Regal International School, London Library and Waxy O'Connor's pub, among other places. Other local landmarks include St Anne's Churchyard (less than half a mile north-west) and Harris Westminster Sixth Form (0.8 miles south). Chinatown has its own railway station: Tottenham Court Road station. Well-known places in the area include Leverian collection (within half a mile south-east) and Montfichet's Tower (1.3 miles east). Not far away are Barnsbury Wood and St. James's Park Lake.
Signs you need gutter sealing in Chinatown
Debris in the gutter keeps water sitting at the joints. Standing water finds the weakest joint and leaks out.
Any of these means the joints need attention:
- Old gutter sealant that has let go
- Wet patches on the wall under a gutter joint
- End caps that drip every time it rains
- Trim joints where the sealant has failed
Managing a site like Soho Parish CofE Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
Comparing quotes
- What happens if the job turns out different
- Who turns up on the day
- How the colour is chosen
- How the surfaces are prepared before sealing
Leave it or put it right?
You don’t need new fascias just because the joints have opened. Sealing the joints tidies them up as long as the boards are in good condition. 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 Chinatown, the repair is bigger than the sealant job would have been.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

What happens on the day
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. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at the gutters, fascias and trims and agree the joints to seal.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Let us know about parking restrictions

Looking after it afterwards
After the cure time, these simple habits help:
- Keep downpipes clear
- Sort out a dripping joint early
- Don’t lean ladders against the gutter itself
- Keep the gutters clear of debris
A sagging gutter needs its brackets checked. If it drops, the joints will open.
A leaking garage frame lets water reach stored items. A reseal sorts it while the frame is sound.
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- Gutters that have dropped or pulled away
- A gutter length that has split
- Problems with the roof covering
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
