Gutter sealing in Mildmay
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. They’re sealed in a matching colour where possible. We work on uPVC fascias, garage door frames and soffit joints, and the jobs we see most are internal damp traced to a gutter joint and wet patches on the wall under a gutter joint.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Mildmay, check the lease for who looks after the outside.
Whatever the size of the job, you get the same 12-month guarantee.

Your questions about gutter sealing in Mildmay
Can you do gutter sealing in Mildmay?
Yes, Mildmay 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.
Is parking an issue for gutter sealing in Mildmay?
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.
What does gutter sealing cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email and tell us what needs doing and where.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you install new fascias or gutters?
No. We seal leaking joints, end caps and trims. A gutter installer or roofer deals with replacement.
Are you fully insured?
Yes, we are fully insured for every job we do.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from an hour or two to a few hours, depending on the amount of work. 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 start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Clear the area around the work
How to get a quote

What we cannot put right
A few problems are outside what sealant work can do:
- Rotten or damaged fascia boards
- A gutter length that has split
- Blocked downpipes
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Where we work in Mildmay
- Roofline trims
- Gutter joints
- Garage door frames
- Soffit joints
- Gutter end caps
- uPVC fascias
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What affects the cost of gutter sealing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The size of the job
- Which sealant suits the joint
- The old material and how stubborn it is
- Mould in or behind the old joints
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- Any previous sealing or DIY work
Getting a quote is simple: tell us what needs doing and where. Photos by email help us understand the job.
What gutter sealing looks like in Mildmay
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Dalston Kingsland station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Managing a site like Newington Green Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Mildmay is about 1 mile north of Hoxton, in Greater London. Jobs in Mildmay get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Mildmay is one of 764 towns and villages in Greater London where we work.

Aftercare tips
A little care helps the new joints last. Our advice:
- Look for streaks or damp on the wall below gutters
- Check that water runs out of the downpipes
- Watch for drips in a downpour
- Keep ladders off the guttering
Check the joints after heavy rain now and then. It’s the easiest time to see a leak.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches.
When to call us in Mildmay
When a gutter sags, its joints open. Resealing a sagging joint will not last, so the gutter needs refixing first.
People usually contact us after spotting one of these:
- Stop ends leaking at the end of a run
- Old sealant on roofline trims that has split
- Old gutter sealant that has let go
- Gaps along fascia and soffit joints
If you live in an older home near Church of St Jude and St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- How the surfaces are prepared before sealing
- How long the guarantee is
- When the joint can take water or movement
- Is VAT in the price?
