Mastic sealing for commercial buildings in Upper Basildon
For blocks and buildings in Upper Basildon and across West Berkshire, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on external wall and movement joints, window and door perimeters on blocks and balcony and threshold joints, and what we’re called in for most is old repairs sealed over failed mastic and window mastic that has split and shrunk. For commercial sealant work in Upper Basildon, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Rural conversions near places like Upper Basildon often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Prioritise elevations facing the weather
- Make mastic part of routine maintenance checks
- Encourage occupiers to report problems at frames
- Reduce knocks to communal area joints
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Cost factors for mastic joints
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Working within restricted access windows
- Travel to remote or island sites
- The total length or number of joints
- The product specified
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Details that help us quote
However big the job, the same details help:
- A wide shot and a close-up of the area
- The postcode of the building
- Asbestos survey details if the building is older
- Rough lengths or quantities, or drawings if you have them
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or email us.
Questions about Upper Basildon
We manage a building near Pangbourne station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Is Upper Basildon too small for you to travel to?
Not at all. Upper Basildon is within our area. 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.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can people stay in the building while you reseal?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Looking after buildings in and around Upper Basildon
At about 45 miles from central London, Upper Basildon is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Upper Basildon included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
Older buildings near Upper Basildon, from historic houses such as Basildon Park, 1.4 miles to the north-east of Upper Basildon, to more modest stock, need compatible products when frames are resealed. Buildings close to stations like Pangbourne station, 2.3 miles to the east of Upper Basildon, are often flats over shops, with frame mastic to keep sound. Trustees of buildings like St Stephen's Church can bring frame and external mastic into a planned maintenance list.
