External mastic for homes and businesses in Midgham Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you have water getting into walls through failed joints and old sealant gone brittle and cracked, we can help, whatever the surface.
Older homes in small places like Midgham Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
We stand behind the work with a 12-month guarantee.

Do you need external mastic in Midgham Green?
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Most people get in touch after spotting something like this:
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
Schools such as Woolhampton C.E. Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before any work starts from the range available.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why act early in Midgham Green
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Where a wall is exposed, as many are in small places like Midgham Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

DIY versus a professional finish
If you are set on DIY, put the effort into 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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.

What we can’t put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Failed render or damaged cladding panels
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

Walls and rooflines in Midgham Green
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Matthew, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Midgham station, outside joints that have cracked can let damp into a rental, so check them between lets.
