Do you need external mastic in Redbridge?
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Keep an eye out for these signs:
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Hard, crazed mastic that has stopped moving
Managing a site like New Hinksey Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

External mastic for homes and businesses in Redbridge
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 so the joint does not stand out. If you have brick movement joints where the sealant has split and moss and dirt in joints with no sealant left, we can help.
Somewhere as small as Redbridge, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
All of our work is guaranteed for twelve months, in Redbridge and everywhere else we cover.

What else we do in Redbridge
What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Why act early in Redbridge
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Around Redbridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

What external mastic looks like in Redbridge
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 Holywell Manor (about 1.9 miles north) are a reminder that the area around Redbridge has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as St Luke's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Oxford station? Then split movement joints are easy to miss on a rental until damp shows inside.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Keep movement joints as flexible joints, not mortar
- Avoid pressure-washing directly into sealant joints
- Act on the first splits you see
- Keep soil, plants and ivy away from the joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
The process
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Redbridge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on

Do you cover smaller places like Redbridge?
Yes, Redbridge 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.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Redbridge, along with the rest of our area.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us with a short description of the job.
