Pilley Bailey External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Pilley Bailey. Fully insured, ARBOMaster approved and guaranteed for a year.
- Leaking joints around cladding and façade panels
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
Should I try it myself first?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
External mastic for homes and businesses in Pilley Bailey
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We work on brickwork movement joints, render & cladding joints and façade panels, and people most often call us about damp patches traced to an open external joint and failed seals between different materials.
Somewhere as small as Pilley Bailey, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, you get the same 12-month guarantee in Pilley Bailey and across Hampshire.

Pilley Bailey buildings and the weather
Pilley Bailey is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Beaulieu Palace House (about 4 miles north-east) nearby, there’s older building stock in the area around Pilley Bailey 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.
If you let a flat or house near Lymington Town station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Saint Nicholas Chapel, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Pilley Bailey: your questions answered
Is external mastic in a coastal place like Pilley Bailey any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Lymington Town station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
When something else is needed
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Damp that is not coming from the joint
- Render that is blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Brickwork movement joints
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Façade panels
When to call us in Pilley Bailey
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Look out for any of the following:
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
Managing a site like William Gilpin Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Pilley Bailey needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

Advice
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never let anyone fill a movement joint with mortar
- Get split or bare joints resealed while the damage is small
- Leave the joints unpainted unless we’ve said otherwise
- Check external joints each spring
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
