About our external mastic in Midgham
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. We’re often asked to deal with joints where the bead has come unstuck and rigid filler in a joint that should flex, across concrete & block, façade panels and joints between brick and frames.
Around Midgham, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
Big or small, you get the same one-year guarantee in Midgham and across West Berkshire.

Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Midgham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

How the visit works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. The work usually takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Midgham needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- 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.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
Ask for a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.

What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
Questions from Midgham
Do you cover smaller places like Midgham?
Yes, Midgham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Midgham for external mastic?
Yes, Midgham is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint does not draw the eye.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Common problems we fix in Midgham
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches traced to an open external joint
- Failed seals between different materials
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
Homes close to Church of St Matthew include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Midgham buildings and the weather
With historic houses such as Shaw House (about 4.9 miles west) nearby, there’s older building stock in the area around Midgham as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Rented homes near Midgham station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Bucklebury C.E. Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
