External mastic in Storrington, done properly
For buildings in Storrington, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on render & cladding joints, joints between brick and frames and concrete & block, and common reasons people get in touch are failed sealant between panels on a façade and joints where the bead has come unstuck.
Homes around Storrington range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why act early in Storrington
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Around Storrington, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Storrington: your questions answered
I let a flat near Pulborough station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Do you cover Storrington for external mastic?
Yes, Storrington is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
What should I tell you?
Tell us what needs doing and where. We’ll ask anything else we need to know.
How much does external mastic cost in Storrington?
Size, access and the old material all affect the cost. Call for a quick quote.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Storrington buildings and the weather
With historic houses such as Parham House (about 2 miles west) nearby, there’s older building stock in the area around Storrington as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to The Parish Church of St Mary the Virgin include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Storrington Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Pulborough station? Then split movement joints are easy to miss on a rental until damp shows inside.

Should I try it myself first?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What affects the quote in Storrington
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- Any mould that needs treating
- The old material and how stubborn it is
- When we can work, for business premises
A few things move the cost up or down: the old material and how easily it comes out, 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
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- Any access issues, like height or stairs
There’s no standard price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
What happens on the day
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. In a smaller place like Storrington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit

What we can’t put right
In fairness, some problems need a different trade:
- Movement that is more than a sealant joint can take
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before you book.

What the job involves on each surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly where it can be done safely.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
