Gutter sealing in Runcton
Across Runcton, we reseal gutter joints, end caps and roofline trims. Low-level work is straightforward, and for higher work, tell us about access and we will confirm what’s needed. If you have earlier gutter repairs that have peeled off and old sealant on roofline trims that has split, we can put it right, on gutter joints, roofline trims and garage door frames alike.
Outside joints can only be sealed when they’re dry, so work in Runcton is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, large or small.

Surface by surface
Roofline trims
Roofline trims rely on sealant at their joints. Split sealant lets water in.
Gutter end caps
Stop ends hold back water at the end of a run. When their seal fails, they drip.
What affects the quote in Runcton
Call for a quick quote. The main things that affect it are:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The product the joint needs
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Gutters that have dropped or pulled away
- Boards that have decayed or split
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Runcton buildings and the weather
Runcton is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as North Mundham Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Chichester station, leaking gutter joints on a rental are best caught before they stain the walls.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Deal with a drip before winter
- Check the gutters during heavy rain
- Watch the wall under the gutters for staining
- Make sure downpipes aren’t blocked
Check the joints after heavy rain now and then. Drips are easiest to spot while it’s raining.
The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.
What happens on the day

- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we’re there.

Questions from Runcton
Does the coastal weather in Runcton affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Chichester station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you clean gutters?
Only around the joints we seal, so the sealant can bond. Cleaning the whole run is a separate job.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Runcton, along with the rest of our area.
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.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
What we’re called out for in Runcton
Debris in the gutter keeps water sitting at the joints. Standing water finds the weakest joint and leaks out.
If you can see any of these, it’s time to have the joints looked at:
- Open joints in fascias and soffits
- Damp patches inside below a leaking gutter
- Cracked sealant along roofline trims
- Stop ends leaking at the end of a run
In the older streets around The Parish Church of St Stephen, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
