Gutter sealing for homes and businesses in Boundstone
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough, as long as the gutter is sound. If you’re dealing with damp on an inside wall under a dripping gutter and water dripping where gutter sections meet, we can put it right, whatever the surface.
In and around Boundstone, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Different surfaces, different methods
Garage door frames
Failed sealant around a garage door frame lets water in. It’s removed and renewed.
Soffit joints
Gaps at soffit joints can let in draughts and insects. A neat seal closes them.
How the visit works
The work is kept neat and contained to the joints we are treating. Expect the work to take an hour or two for a few joints, longer for a full run, and we explain the cure time before we leave. In a smaller place like Boundstone, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we find the drip and check the gutter is not cracked or sagging.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- 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
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Deal with a drip before winter
- Clear leaves and moss from the gutters
- Watch for drips in a downpour
- Don’t lean ladders against the gutter itself
Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.
What gutter sealing looks like in Boundstone
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Farnham Castle (about 2 miles north) nearby, there’s older building stock in the area around Boundstone as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near St Timothy, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Farnham station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

FAQs for Boundstone
I let a flat near Farnham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Boundstone?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
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.
Is the work guaranteed?
All our work carries a one-year guarantee.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
When to call us in Boundstone
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end.
Look out for any of the following:
- Internal damp traced to a gutter joint
- Wet patches on the wall under a gutter joint
- Earlier gutter repairs that have peeled off
- Rain getting in around a garage door
If you look after a building such as St Peter's CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Why act early in Boundstone
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Proper preparation is the difference. Around Boundstone, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re 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 fails, we can still redo it.
