Gutter sealing in Sonning
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where possible. We are often asked to deal with damp patches inside below a leaking gutter and open joints in fascias and soffits, across gutter joints, uPVC fascias and garage door frames.
Somewhere as small as Sonning, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
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 fails, we can still redo it.
Landlords, agents and businesses in Sonning
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
What we can’t put right
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Fascias that need replacing
- Water backing up from a blocked pipe
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Common questions in Sonning
Will you come out to Sonning?
Yes. Sonning is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do gutter sealing in Sonning?
Yes. Our work covers London and the South East, and Sonning is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Can you reach high gutters?
Single-storey work is the most straightforward. For anything higher, we’ll confirm what access is needed once we know more.
Can a leaking gutter joint be sealed?
In many cases, yes. A clean, dry joint resealed with gutter sealant generally stops the drip. If the section is split or warped, it needs replacing.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Where do you work from?

Yes. Full insurance covers our work.
Gutter sealing in Sonning: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Sonning Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Different surfaces, different methods
uPVC fascias
Our work is the joints, not new fascias. Damaged boards need replacing by an installer.
Soffit joints
Open soffit joints let draughts in. We close them with a suitable sealant.
Do you need gutter sealing in Sonning?
End caps get knocked or pushed by water. Once the seal behind them fails, they drip and runs down the wall.
If you can see any of these, it’s time to have the joints looked at:
- Streaks down the brickwork from a leaking joint
- Rain getting in around a garage door
- Water dripping where gutter sections meet
- Damp on an inside wall under a dripping gutter
For an older house near a landmark such as St Andrew's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Related advice
Leave it or put it right?
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. Around Sonning, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
