How we handle external mastic in Parker's Green
On houses, flats and commercial buildings across Parker's Green, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Typical jobs include leaking joints around cladding and façade panels and hard, crazed mastic that has stopped moving, on concrete & block, joints between brick and frames and façade panels.
Around Parker's Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

When to call us in Parker's Green
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
Homes close to St Andrew include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What else we do in Parker's Green
Walls and rooflines in Parker's Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Old Soar Manor (about 3.4 miles north) are a reminder that the area around Parker's Green 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.
Rented homes near Tonbridge station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Woodlands Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Concrete & block
- Render & cladding joints
- Copings & trims
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
Why act early in Parker's Green
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. In a small place like Parker's Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

FAQs for Parker's Green
Is Parker's Green within the area you cover?
Yes, Parker's Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Tonbridge station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Parker's Green, along with the rest of our area.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Somewhere like Parker's Green 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.
- First, the joints are inspected and the access agreed.
- 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.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
