Gutter Sealing in West Marden
We cover West Marden for sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old sealant removed completely, joints prepared properly.
- Streaks down the brickwork from a leaking joint
- Internal damp traced to a gutter joint
- Failed sealant on a garage door frame
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
About our gutter sealing in West Marden
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 uPVC fascias, gutter joints and garage door frames, and people most often call us about fascia boards with gaps between them and wet patches on the wall under a gutter joint.
Around West Marden, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job, whatever its size.

Advice
Leave it or put it right?
Replacing fascias because of open joints is usually unnecessary. A neat seal closes the gaps as long as the boards are in good condition. Around West Marden, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What guarantee comes with the job?
You get our 12-month guarantee on every job.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Can sealant stop a sagging gutter leaking?
Not for long. The joint will pull apart so the gutter has to be refixed first.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Do you replace gutters or fascias?
No. We seal leaking joints, end caps and trims. A gutter installer or roofer deals with replacement.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Get leaks sealed before the wet months
- Check the gutters during heavy rain
- Glance at the soffit joints now and then
- Look for streaks or damp on the wall below gutters
Look at fascia and trim joints when you’re checking the gutters. A small split is quicker to put right.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards.
What affects the cost of gutter sealing
There’s no set price list, because jobs vary so much. What we look at:
- How many rooms, windows or areas are involved
- Access and height
- Any working-time requirements on site
- The old material and how stubborn it is
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Gutter sealing in West Marden: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Uppark (about 2.6 miles north) are a reminder that the area around West Marden has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Compton and Up Marden CofE Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to The Parish Church of St Mary include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Rowlands Castle station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What sealant work can’t fix
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- Gutters that have dropped or pulled away
- A gutter length that has split
- Blocked downpipes
