Gutter sealing for homes and businesses in Sandhurst
We work across Sandhurst on leaking gutter joints and roofline trims. Low-level work is straightforward and if it’s higher up, let us know and we will confirm what access is needed. Typical jobs include gaps along fascia and soffit joints and streaks down the brickwork from a leaking joint, across gutter end caps, roofline trims and garage door frames.
Around Sandhurst, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Questions from Sandhurst
Is Sandhurst within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Robertsbridge station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What does gutter sealing cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours, depending on the number of joints and the access. We will tell you when we quote.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Leave it or put it right?
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Around Sandhurst, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

What happens on the day
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on the number of joints and the access. Somewhere like Sandhurst needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we are there.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How we quote for gutter sealing
There’s no set price list. What we look at:
- How easy the joints are to reach
- The product the joint needs
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or send us an email.

Outside joints around Sandhurst
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Great Dixter (about 2.4 miles south-east) are a reminder that the area around Sandhurst has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Sandhurst Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Robertsbridge station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near Mission Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips
After the cure time, these simple habits help:
- Check that water runs out of the downpipes
- Check fascia and soffit joints for gaps
- Rest ladders on the wall, not the gutter
- 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.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it while the frame is sound.
Surface by surface
Gutter joints
Most gutter leaks start at a joint between sections. They’re cleaned out, dried and resealed.
uPVC fascias
Fascia board joints can open up. We seal them neatly with a matching sealant where possible.
