Cane End External Mastic
External mastic for Cane End, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Old sealant gone brittle and cracked
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a small place like Cane End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

About our external mastic in Cane End
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. Typical jobs include hard, crazed mastic that has stopped moving and brick movement joints where the sealant has split, on concrete & block, brickwork movement joints and copings & trims.
External sealant needs dry, clean surfaces, so work around Cane End is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How much does external mastic cost in Cane End?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email and let us know what needs doing and where.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you need from me for a quote?
Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch, so the joint stops doing its job. If it has already been filled, we can normally cut it out and reseal it.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.

How the job changes by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
When to call us in Cane End
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
For an older house near a landmark such as Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Cane End needs a little journey planning: 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.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit

Related advice
External mastic in Cane End: local notes
With historic houses such as Mapledurham House (about 1.9 miles south) nearby, there’s older building stock in the area around Cane End as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Kidmore End Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Tilehurst station, split movement joints are easy to miss on a rental until damp shows inside.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Wash walls gently around the sealant
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
