Pedlars End External Mastic
Our applicators work in Pedlars End on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
External mastic in Pedlars End
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on joints between brick and frames, copings & trims and render & cladding joints, and common reasons people get in touch are sealant pulling away from one side of the joint and brick movement joints where the sealant has split.
Outside joints can only be sealed when they’re dry, so work in Pedlars End is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Older cottages and farmhouses around Pedlars End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
FAQs for Pedlars End
Will you come out to Pedlars End?
Yes, Pedlars End is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is external mastic in Pedlars End guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
How do you reach high-level joints?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Pedlars End.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep water from gutters off the wall
- Don’t let climbing plants root in the sealant
- Check external joints each spring
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
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.
Do you need external mastic in Pedlars End?
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
In the older streets around Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- How long to leave it before use
- Is the old sealant removed completely?
- What product goes in the joint
- Are they insured?
