About our gutter sealing in Barnham
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We work on roofline trims, uPVC fascias and soffit joints, and common reasons people get in touch are old gutter sealant that has let go and failed sealant on a garage door frame.
Somewhere as small as Barnham, homes and farm buildings often face open ground, 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.
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.

What affects the quote in Barnham
We don’t publish a price list, because jobs vary so much. What we look at:
- The number and length of the joints
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Working hours on commercial sites
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
Helping us quote
When you call or email, it’s useful to know:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- The type of property
- How we’d reach the joints
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
When something else is needed
We will not take on work that won’t last, so these are the limits:
- Guttering that needs replacing
- Boards that have decayed or split
- Brackets that have snapped or loosened
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Barnham buildings and the weather
Barnham is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. 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 an older house near a landmark such as The Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Barnham Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What the job involves on each surface
Gutter joints
A gutter joint has to cope with movement and standing water. A gutter sealant made for the job holds best.
Soffit joints
Gaps at soffit joints can let in draughts and insects. A neat seal closes them.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
When to call us in Barnham
Leaves and moss hold water in the gutter. Standing water finds the weakest joint and leaks out.
These are the problems we’re asked about most:
- Trim joints where the sealant has failed
- Earlier gutter repairs that have peeled off
- Fascia boards with gaps between them
- Failed sealant on a garage door frame
For landlords with property near Barnham station, leaking gutter joints on a rental are best caught before they stain the walls.
What your quote should include
- What product goes in the joint
- Whether they seal over old material or remove it
- How long the guarantee is
- Whether they’re fully insured
Leave it or put it right?
A new garage door is not needed for a leaking frame. Resealing the frame joint is often enough. Where a wall is exposed, as many are in small places like Barnham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a few hours. Somewhere as small as Barnham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work
- Clear the area around the work

FAQs for Barnham
Do you cover smaller places like Barnham?
Yes. Barnham 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.
Does the coastal weather in Barnham affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Is it possible to stop a gutter joint dripping with sealant?
Generally, if the gutter is sound. The joint is cleaned and dried first so the seal holds.
Can sealant stop a sagging gutter leaking?
Sealant won’t hold a sagging gutter. A gutter installer needs to refix it.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you guarantee gutter sealing?
Every job comes with our one-year guarantee.
