How the visit works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before work begins. Most jobs take an hour or two for a few joints, longer for a full run. For a village or hamlet like Alciston, the journey is planned in advance: 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 find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Before we arrive
- Keep children and pets away from the work area
- Tell us if parking is tricky
- Tell us about any water getting in

Advice
Gutter sealing in Alciston
We seal leaking gutter joints, end caps, fascia and soffit joints, along with roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. We work on uPVC fascias, garage door frames and gutter end caps, and common reasons people get in touch are earlier gutter repairs that have peeled off and cracked sealant along roofline trims.
Around Alciston, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee, large or small.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Clean out the gutters once or twice a year
- Look along the fascias for open joints
- Look at the gutters while it’s raining
- Keep ladders off the guttering
Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp.
What affects the quote in Alciston
For a quick quote, just ask. What matters most is:
- The product the joint needs
- The number and length of the joints
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- The type of property
- Pictures of the joints, sent by email
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or email us.

Why act early in Alciston
Replacing fascias because of open joints is normally unnecessary. Sealing the joints tidies them up if the boards are sound. Older cottages and farmhouses around Alciston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What gutter sealing looks like in Alciston
Historic houses like Charleston Farmhouse (about 1.3 miles north-west) are a reminder that the area around Alciston has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Berwick (Sussex) station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near The Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Alciston questions
I let a flat near Berwick (Sussex) station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Alciston?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Do you work on high-level gutters?
That depends on the building. Tell us the height and what’s around the gutter and we’ll confirm what’s needed.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Will you clear out my gutters?
We clear debris around the joints we are sealing. A full clean of the gutters is not part of it.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
