About our mastic sealing in Middle Assendon
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. Most enquiries involve damaged joints in communal entrances and corridors and draught complaints from residents or tenants, on communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms. Facilities teams, main contractors and managing agents in Middle Assendon tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions near places like Middle Assendon 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.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or send details through our quote form and we will come back to it.

Leave it or put it right?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes and those cost far more to put right. One visit to deal with every failing joint makes more sense than several trips to a place like Middle Assendon, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Middle Assendon is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 36 miles from Middle Assendon. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
With historic buildings such as Greys Court (to the south-west of Middle Assendon) in the wider area, owners of older properties around Middle Assendon should expect mastic to need a product that suits old masonry.

Middle Assendon: questions and answers
Can you quote for a block close to Henley-On-Thames 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.
Is Middle Assendon too far out for you?
No. Places such as Middle Assendon are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. If others near Middle Assendon need work, visits can be combined. A fixed quote is given before anything starts.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
What we need from you
- Have the specification and drawings to hand
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Advice
Do you need mastic sealing in Middle Assendon?
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Typical triggers for a call:
- Cracked, hardened mastic round windows on a block
- Old repairs sealed over failed mastic
- Repeated reactive repairs to the same buildings
- Damaged joints in communal entrances and corridors
If you look after a block within reach of Henley-On-Thames station, 2.7 miles south-east of Middle Assendon, frame and balcony mastic can be renewed on one programme.

After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Share the asbestos register when you send details
- Share your contractor requirements early
- Include mastic in your cyclical inspections
- Track which buildings were done and when
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
