About our gutter sealing in Blackwall
A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Resealing it is a small job while the gutter is still sound. We work on roofline trims, uPVC fascias and garage door frames, and the jobs we see most are water dripping where gutter sections meet and damp on an inside wall under a dripping gutter.
Outside work in London starts with access: side passages, upper floors and where to park. In Blackwall, joints up high may need ladders or other access, which is worth talking through when you book.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

What gutter sealing looks like in Blackwall
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Queen's House (about 1.7 miles south) nearby, there’s older building stock in the area around Blackwall as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Woolmore Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as All Saints Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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.
Quotes for gutter sealing in Blackwall
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints

- The number of rooms or windows
- The old material and how stubborn it is
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What we need to know
When you contact us, it’s useful to know:
- Whether it has been sealed before
- A few photos by email, if you can

Common questions in Blackwall
Is parking a problem for a job in Blackwall?
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.
I let a flat near Canary Wharf station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you clean gutters?
We clear debris around the joints we are sealing. Full gutter cleaning is a separate job.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before work begins.
Can you reach high gutters?
Low gutters are simple to reach. If it’s higher up, let us know and we will confirm the access.
How the visit works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job normally takes an hour or two for a few joints, longer for a full run, and we tell you how long to leave it before we go. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents 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.
How to prepare

Ask for a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand.
Related advice
When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Guttering that needs replacing
- Boards that have decayed or split
- Water backing up from a blocked pipe
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
- Garage door frames
- Soffit joints
- Gutter end caps
- Gutter joints
- uPVC fascias
- Roofline trims
Do you need gutter sealing in Blackwall?
End caps get knocked or pushed by water. If the seal fails, water escapes at the end and runs down the wall.
It’s worth asking for a quote if you see:
- Wet patches on the wall under a gutter joint
- Internal damp traced to a gutter joint
- Water dripping where gutter sections meet
- Fascia boards with gaps between them
If you let a flat or house near Canary Wharf station, leaking gutter joints on a rental are best caught before they stain the walls.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Look along the fascias for open joints
- Sort out a dripping joint early
- Clean out the gutters once or twice a year
- Get a dropping gutter looked at quickly
Leave the new sealant to cure as we advise before poking or cleaning near it.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.
