Your questions about external mastic in Durrants
Does the coastal weather in Durrants affect outside sealant?
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.
Do you work for landlords with property near Rowlands Castle station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Where are you based?
We work from Crawley. Our applicators cover Durrants, along with the rest of our area.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
How we handle external mastic in Durrants
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you’re dealing with leaking joints around cladding and façade panels and rigid filler in a joint that should flex, we can put it right.
Older homes in small places like Durrants may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Outside joints around Durrants
Durrants is close to 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 movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Warblington Castle (about 2.5 miles south) are a reminder that the area around Durrants 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.
Rented homes near Rowlands Castle station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Havant Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. In the older streets around St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Somewhere like Durrants needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Clear the area around the work

Advice
How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Why it’s worth doing now in Durrants
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Durrants, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
- Structural movement, which needs a surveyor or engineer

- The number and length of the joints
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
