Your questions answered
Is Calcot off your patch?
No. Places such as Calcot are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you take on a block within reach of Theale station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
About our mastic sealing in Calcot
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are occupiers reporting cold air round windows and old repairs sealed over failed mastic. One point of contact handles commercial sealant work in Calcot from the first photos to the final walk-round, for single jobs and planned programmes alike.
Converted and older buildings in and around Calcot often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Blocks and managed buildings in Calcot
Calcot is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 41 miles from Calcot. Within reach of London, blocks run by agents and associations are common around stations.
Schools and community buildings such as Calcot Infant School and Nursery need frame and external mastic kept sound like any building. Churches, halls and community buildings such as Church of St Michael are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Buildings close to stations like Theale station, 1.2 miles south-west of Calcot, are often flats over shops, with frame mastic to keep sound.
Calcot is about 3 miles west of Reading, in West Berkshire. Calcot sits inside our coverage and the rest of West Berkshire, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 140 places in West Berkshire.
Postcode districts covered here: RG31. Buildings on Curtis Road, Barclay Road and Royal Avenue are within our area. Just outside Calcot, we also work in Beansheaf Farm (1 mile south-east), Fords Farm (1 mile east), Horncastle (1 mile east), Little Heath (1 mile north) and Theale (1 mile west).

Recent enquiries here include premises near Murdochs pub, Little Heath School and Calcot Park. For rail, the closest station is Theale station, about 1.2 miles south-west. A little further out are Broad Street Mall (3.3 miles east) and Battle Hospital (2.5 miles north-east). Not far away are Moor Copse Nature Reserve and Hosehill Lake.
After the work
A few simple habits keep the new joints working:
- Have the asbestos survey to hand for older buildings
- Avoid piecemeal callouts where you can
- Reduce knocks to communal area joints
- Track which buildings were done and when
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Water coming in from the roof or rainwater goods
