How we handle external mastic in Penton Grafton
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. Typical jobs include panel joints letting water in and moss and dirt in joints with no sealant left, across concrete & block, brickwork movement joints and joints between brick and frames.
Around Penton Grafton, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What affects the quote in Penton Grafton
The price is agreed before any work begins. It’s based on:
- Any mould that needs treating
- The number of rooms or windows
- How easy the joints are to reach
- When we can work, for business premises
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Common problems we fix in Penton Grafton
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
It’s worth asking for a quote if you see:
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
If you live in an older home near Holy Trinity Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep high-pressure jets off the joints
- Make sure movement joints aren’t pointed over
- Act on the first splits you see
- Clear growth from the base of walls and joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
What external mastic looks like in Penton Grafton
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.
Letting a property close to Andover station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Harrow Way Community School, its movement joints, gutters and trims need looking after like any other building’s.

Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. In a small place like Penton Grafton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

FAQs for Penton Grafton
Can you do external mastic in Penton Grafton?
Yes. Our work covers London and the South East, and Penton Grafton is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Will you come out to Penton Grafton?
Yes. Penton Grafton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Penton Grafton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- 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.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
