How it works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours, depending on the number of joints and the access. In a smaller place like Findon Valley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we agree which joints need sealing.
- We clean out each joint.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in

Surface by surface
Soffit joints
Gaps at soffit joints can let in draughts and insects. We close them with a suitable sealant.
Gutter joints
When a joint drips, the gutter is often still sound. Resealing is generally enough.
Findon Valley buildings and the weather
Historic houses like Ecclesden Manor (about 3.5 miles south-west) are a reminder that the area around Findon Valley has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near West Worthing station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. In the older streets around All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What else we do in Findon Valley
What affects the cost of gutter sealing
We quote each job individually. This is what makes a difference:
- Whether there’s mould to deal with
- Any working-time requirements on site
- The old material and how stubborn it is
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
To make quoting easier, let us know:
- If someone has resealed it before
- Photos by email, if that’s easy
- Where the job is, and your postcode
- Any access issues, like height or stairs
To get a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before any work starts.
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Signs you need gutter sealing in Findon Valley
Sagging sections pull joints apart. Resealing a sagging joint will not last so the brackets need attention first.
Common reasons people contact us are:
- Fascia boards with gaps between them
- Rain getting in around a garage door
- Water running down the wall below the gutter
- Drips from gutter joints and end caps
For site and facilities teams at buildings such as Vale School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- How long the guarantee is
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- Are they insured?
How to look after the new joints
A little care helps the new joints last. We recommend:
- Clean out the gutters once or twice a year
- Sort out a dripping joint early
- Check fascia and soffit joints for gaps
- Keep ladders off the guttering
Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.
