About our gutter sealing in Gunville
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough, as long as the gutter is sound. Common call-outs are for damp on an inside wall under a dripping gutter and old sealant on roofline trims that has split, across gutter end caps, gutter joints and soffit joints.
In a village or hamlet like Gunville, older cottages and farm buildings often stand in the open, 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, in Gunville and everywhere else we cover.

Outside joints around Gunville
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Carisbrooke Castle (about 0.8 miles south-east) nearby, there’s older building stock in the area around Gunville 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 Carisbrooke College are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What affects the cost of gutter sealing
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site
- Which sealant suits the joint
- Any mould that needs treating
- How much there is to do
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.
Helping us quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Photos by email, if that’s easy
- Any previous sealing or DIY work
- Whether it’s a home or a business
If you are in Gunville and need gutter sealing, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and you’ll get a clear quote before any work starts.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Surface by surface
Roofline trims
We reseal trim joints with an exterior sealant suited to the material.
Gutter end caps
End caps are resealed where they meet the gutter, after cleaning and drying.
How it works
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on the number of joints and the access for a typical job. In a small place like Gunville, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
Aftercare tips
Good habits help new joints last longer. Our tips:
- Do not lean ladders against the gutter itself
- Keep an eye out for wet patches below a joint
- Sort out a dripping joint early
- Check that water runs out of the downpipes
Check the joints after heavy rain. Drips are easiest to spot while it’s raining.
A drip from a gutter joint will not stop on its own. Water keeps hitting the same part of the wall, which can lead to staining and damp.
What we’re called out for in Gunville
When a gutter sags, its joints open. Sealing will not hold if the gutter keeps dropping so the brackets need attention first.
Any of these means the joints need attention:
- Stop ends leaking at the end of a run
- Quick sealant fixes on gutters that didn’t last
- Damp patches inside below a leaking gutter
- Trim joints where the sealant has failed
If you live in an older home near St. Mary's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before you book
- Whether all the old sealant comes out first
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Which colour the sealant will be
FAQs for Gunville
Do you cover smaller places like Gunville?
Yes, Gunville is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with gutter sealing in Gunville?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
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.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you install new fascias or gutters?
No, we reseal joints, end caps and trims. A gutter installer or roofer deals with replacement.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How do I get a quote for gutter sealing in Gunville?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
When it isn’t the sealant

- Gutters that have dropped or pulled away
- Blocked downpipes
- Guttering that needs replacing
