Nursling External Mastic
Our applicators work in Nursling on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
External mastic for homes and businesses in Nursling
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for failed seals between different materials and joints with sealant missing in places, on render & cladding joints, brickwork movement joints and façade panels.
Around Nursling, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

When to call us in Nursling
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Most people get in touch when they notice something like this:
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
For site and facilities teams at buildings such as Nursling Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. For a job in Nursling, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed

Your questions about external mastic in Nursling
Do you cover smaller places like Nursling?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Redbridge station?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, large or small.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What external mastic looks like in Nursling
Nursling is within about 2 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 movement joints and outside wall 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Redbridge station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Lord's Hill Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What affects the quote in Nursling
You’ll get a clear quote before any work starts. It takes into account:
- Any working-time requirements on site
- Any mould that needs treating
- Whether the work is at height
- Which sealant suits the joint
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 go through it with you.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it’s a home or a business
- How we’d reach the joints
- How many joints, rooms or windows are involved
- The address or postcode of the job
For a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep water from gutters off the wall
- Check external joints each spring
- Leave the joints unpainted unless we’ve said otherwise
- Keep high-pressure jets off the joints
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

What we can’t put right
Before booking, it’s worth knowing the limits:
- Cracking across the wall rather than at a joint
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Façade panels
- Copings & trims
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
Should I try it myself first?
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, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
