DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
External mastic in Ottershaw, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you’re dealing with weeds or debris growing in open joints and failed seals between different materials, we can help, whatever the surface.
Around Ottershaw, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Ottershaw: your questions answered
I let a flat near Chertsey station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Ottershaw in your area for external mastic?
Yes. Our work covers London and the South East, and Ottershaw is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on the building. Parking around Ottershaw is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention any tricky access
- Mention if the joints have been sealed before
- Tell us if parking is tricky

What external mastic looks like in Ottershaw
Historic houses like Botleys Mansion (about 0.8 miles north) are a reminder that the area around Ottershaw has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Chertsey station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Ottershaw Christchurch Church of England Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
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.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Why deal with it now?
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Ottershaw, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

What we’re called out for in Ottershaw
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Most people get in touch when they notice something like this:
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
Homes close to Christ Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
