Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
- Keep soil, plants and ivy away from the joints
- Show decorators and builders where the movement joints are
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
About our external mastic in Afton Park
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. We work on copings & trims, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are cracked joints where brick meets render or frames and weathered mastic that no longer stretches.
In a village or hamlet like Afton Park, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Why it’s worth doing now in Afton Park
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 Afton Park, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Afton Park buildings and the weather
Afton Park is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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 Mottistone Manor (about 3.8 miles south-east) are a reminder that the area around Afton Park 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.
Homes close to St. Agnes' Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Afton Park is about 6 miles south of Lymington, in the Isle of Wight.

FAQs for Afton Park
Do you cover Afton Park for external mastic?

Will you come out to Afton Park?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long before the joint can be used?

Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.
What information do you need?
Let us know what needs doing and where. If we need more, we’ll ask.
When to call us in Afton Park
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
Keep an eye out for any of the following:
- Old sealant gone brittle and cracked
- Moss and dirt in joints with no sealant left
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
For site and facilities teams at buildings such as All Saints Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Different surfaces, different methods
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
What happens on the day
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Afton Park, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on
