We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. If you are dealing with joints with sealant missing in places and moss and dirt in joints with no sealant left, we can help.
Outbuildings, garages and conservatories around homes in places like Stoke Poges add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.

Why it’s worth doing now in Stoke Poges
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Stoke Poges, 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 about the job first.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Questions from Stoke Poges
Can you do external mastic in Stoke Poges?
Yes, Stoke Poges is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Slough station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Where are you based?
Mr Mastic is based in Crawley. We cover Stoke Poges and the rest of Slough, along with the rest of our area.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Are you insured?
Yes. We’re fully insured.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render.

Outside joints around Stoke Poges
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. Historic houses like Windsor Castle (about 4.3 miles south) are a reminder that the area around Stoke Poges has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as The Stoke Poges School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Slough station? Then split movement joints are easy to miss on a rental until damp shows inside.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Façade panels
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Clear growth from the base of walls and joints
- Check external joints each spring
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

How the visit works
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do.

- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.

Advice
Common problems we fix in Stoke Poges
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
Keep an eye out for these signs:
- Moss and dirt in joints with no sealant left
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
If you live in an older home near St Andrew's Church Centre, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
