External Mastic in Weedon
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Weedon. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
- Weeds or debris growing in open joints
How we handle external mastic in Weedon
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We are often asked to deal with weeds or debris growing in open joints and hard, crazed mastic that has stopped moving, on façade panels, copings & trims and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Weedon is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Every job is covered by our one-year guarantee, wherever you are in Buckinghamshire.

What else we do in Weedon
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Older cottages and farmhouses around Weedon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why choose Mr Mastic in Weedon
- Experience in homes, commercial sites and hotels
- Full insurance on every job
- Old sealant always removed completely
- You choose the colour before work begins
Signs you need external mastic in Weedon
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Keep an eye out for these signs:
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Cracked joints where brick meets render or frames
Schools such as Old School Room Chapel are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

We bring what the job needs, so it can be finished in one trip 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.

Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask before painting over external sealant
- Act on the first splits you see
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
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, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
