Gutter sealing in Avon Castle
A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. We work on garage door frames, gutter joints and soffit joints, and the jobs we see most are old sealant on roofline trims that has split and damp on an inside wall under a dripping gutter.
In a village or hamlet like Avon Castle, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Avon Castle: your questions answered
What guarantee comes with gutter sealing in Avon Castle?
All our work, in Avon Castle and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover Avon Castle for gutter sealing?
Yes, Avon Castle is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Will you clear out my gutters?
We clean the joints we’re sealing and any debris nearby is cleared. Cleaning the whole run is a different job.
Is sealing fascia joints something you do?
Yes. Open joints along uPVC fascias and soffits can be sealed in a colour to suit.
Do you install new fascias or gutters?
Replacement isn’t our trade. If a gutter is broken or sagging, we’ll tell you.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Should I try DIY first?
You can, for simple jobs. 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.
Gutter sealing in Avon Castle: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Avon Tyrrell House (about 3.5 miles south-east) nearby, there’s older building stock in the area around Avon Castle as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

What else we do in Avon Castle
Leave it or put it right?
You do not need to replace a garage door because rain gets in round the frame. Sealing the frame generally stops it. Where a wall is exposed, as many are in small places like Avon Castle, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Honest limits
Before booking, it’s worth knowing the limits too:

Joints and surfaces we work on
- Gutter end caps
- uPVC fascias
- Garage door frames
- Roofline trims
- Soffit joints

What we are called out for in Avon Castle
Debris in the gutter keeps water sitting at the joints. Water that can’t drain works its way through a weak joint and drips through.
The problems people usually mention when they call are:
- Dripping gutter ends
- Leaking gutter joints and stop ends
- Garage door frames letting rain in
- Damp patches inside below a leaking gutter
If you look after a building such as St Ives Primary & Nursery School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- How the joint is cleaned and prepared
- Whether you can choose the colour
- The length of the guarantee
- What happens if they find a problem under the old sealant
The process
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours, depending on the number of joints and the access in most cases. In a small place like Avon Castle, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we find the drip and check the gutter is not cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- We make sure the joint is dry before sealing.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.
Before we arrive
- Mention any parking rules near the property
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

How to look after the new joints
To keep the joints looking good and working properly:
- Look at the gutters while it’s raining
- Don’t leave a sagging gutter
- Check that water runs out of the downpipes
- Sort out a dripping joint early
Make sure downpipes are not blocked, so water can get away. A blocked pipe backs water up to the joints.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.
Surface by surface
Gutter joints
When a joint drips, the gutter is often still sound. Resealing is usually enough.
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
