South Mundham buildings and the weather
South Mundham is within about 2 miles of 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like North Mundham Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Chichester station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

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.
uPVC fascias
Our work is the joints, not new fascias. If boards are damaged, we’ll tell you.
How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes an hour or two for a few joints, longer for a full run. Somewhere as small as South Mundham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

Your questions about gutter sealing in South Mundham
Can you help a landlord with a rental near Chichester station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is gutter sealing in a coastal place like South Mundham any different?
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.
Is the work guaranteed?
There’s a 12-month guarantee on every job, gutter and fascia work included.
Can sealant stop a sagging gutter leaking?
Not for long. The joint will pull apart, so the fall and brackets need sorting first.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Do you work on high-level gutters?
That depends on the building. Let us know the height and the ground below and we’ll confirm what’s needed.
Do you work in South Mundham?
Yes. We work in South Mundham and the rest of West Sussex, as part of our work across South East England, London and Scotland. For a quote, call 0345 464 0079 or drop us an email.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Housing providers, facilities teams and property managers book us too in South Mundham and across West Sussex. Several sites can go on one quote.
How to look after the new joints
To keep the joints looking good and working properly:
- Do not lean ladders against the gutter itself
- Keep downpipes clear
- Keep an eye out for wet patches below a joint
- Glance at the soffit joints now and then
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry.
Signs you need gutter sealing in South Mundham
Sealant on fascias and trims weathers like any outdoor joint. It goes hard, cracks and pulls away after some years.
Any of these means the joints need attention:
- Gaps along fascia and soffit joints
- Old sealant on roofline trims that has split
- Leaking gutter joints and stop ends
- Dripping gutter ends
If you live in an older home near The Parish Church of St Stephen, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Quotes for gutter sealing in South Mundham
There’s no set price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- Access and height
- The number of rooms or windows
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
When you call or email, it’s useful to know:
- Any access issues, like height or stairs
- The address or postcode of the job
- The problem you’ve noticed
- Photos by email, if that’s easy
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or send us an email.
What happens if it’s left?
Sealant will not clear a blocked downpipe. We check the cause first and tell you if something else is needed. Older cottages and farmhouses around South Mundham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
