Walls and rooflines in Horndean
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Warblington Castle (about 4.8 miles south-east) are a reminder that the area around Horndean 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.
For site and facilities teams at buildings such as Horndean Technology College, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Rowlands Castle station? Then leaking gutter joints on a rental are best caught before they stain the walls. For an older house near a landmark such as Saint Wilfrid's, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Gutter sealing in Horndean, done properly
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on roofline trims, gutter joints and garage door frames, and people most often call us about stop ends leaking at the end of a run and rain getting in around a garage door.
Around Horndean, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Each joint between different materials moves in its own way, so the sealant has to cope with that.
Each job carries a 12-month guarantee.

How we quote for gutter sealing
There’s no set price list, because jobs vary so much. What we look at:
- The product the joint needs
- The amount of work
- How many areas need sealing
- How easy the joints are to reach
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The address or postcode of the job
- The rough size of the job
- If someone has resealed it before
- The type of property
We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or drop us an email.
The process
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. The work generally takes an hour or two for a few joints, longer for a full run. A visit in Horndean needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- We make sure the joint is dry before sealing.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Keep children and pets away from the work area
How to get a quote
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Advice

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. 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.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Do not leave a sagging gutter
- Get leaks sealed before the wet months
- Watch the wall under the gutters for staining
- Don’t lean ladders against the gutter itself
Give the sealant the cure time we tell you before poking or cleaning near it.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.

Is there a guarantee on gutter sealing in Horndean?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
When is the sealant fully cured?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours, depending on the number of joints and the access. We will give you a better idea when we quote.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
What happens if it’s left?
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. In Horndean, as anywhere, most leaks start as a small gap in a joint, and early is when they’re cheapest and quickest to sort.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- An ARBOMaster approved applicator
- A sealant colour to suit the surroundings
- A choice of colours where the product allows
- We never seal over old sealant

- Blocked downpipes
- A gutter length that has split
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.
