Mastic sealing around Aldermaston: points for this area
Central London is about 46 miles from Aldermaston. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Aldermaston sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first.
Property owners at sites such as Fronds Park Business Park (0.8 miles north of Aldermaston) can have mastic renewed between lettings. Schools and community buildings such as Aldermaston C.E. Primary School need frame and external mastic kept sound like any building.
Aldermaston is about 2 miles north of Tadley, in West Berkshire. We cover commercial sites throughout Aldermaston, for single jobs and planned programmes alike. Aldermaston is one of 140 places we cover in West Berkshire. For work in that direction, see our Reading page, about 9 miles away.

Mastic sealing in Aldermaston
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. Most enquiries involve a mix of products and colours from past repairs and repeated reactive repairs to the same buildings, on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks. Looking for mastic applicators who cover Aldermaston? We have been sealing commercial buildings since 2005.
Around smaller places like Aldermaston, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Signs you need mastic sealing in Aldermaston
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
What tends to prompt an enquiry:
- Leaks at window and door perimeters
- No planned programme for sealant
- Patchy repairs in mismatched sealant
- Mastic failing across several blocks on an estate
Blocks of flats and mixed-use buildings often cluster around stations such as Aldermaston station, 1.4 miles to the north-east of Aldermaston, and their window and balcony mastic tends to age at the same rate across a building.
What your quote should include
- What site paperwork they can supply
- Their plan for phasing and protecting the area
- Will failed sealant be removed rather than covered?
- Proof of insurance
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Broken glass or failed sealed units
- Asbestos-containing sealant, which we don’t remove
- Leaks through the frame itself rather than the perimeter
If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer.

What else we do in Aldermaston
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Plan resealing building by building rather than complaint by complaint
- Make mastic part of routine maintenance checks
- Keep bins and bikes away from communal door frames
- Check the asbestos register before any old mastic is disturbed
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Questions about Aldermaston
Is Aldermaston too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
We manage a building near Aldermaston station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
How long does a typical visit take?
It depends on the scope, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
