How we handle mastic sealing in Shirburn
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you’re dealing with no planned programme for sealant and open joints in brickwork or panels, we can help, whatever the surface. Searching for sealant specialists in Shirburn? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around smaller places like Shirburn, 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Misted or failed double-glazed units
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks from above rather than through a joint
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
What we seal
- External wall and movement joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Balcony and threshold joints
What happens if it’s left?
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. For buildings around smaller places like Shirburn, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

How the job changes by surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Looking after the joints
Regular inspection catches problems early. In particular:
- Have the asbestos survey to hand for older buildings
- Look at the sunniest and most exposed elevations first
- Share your contractor requirements early
- Make it easy for occupiers to report draughts
If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it unless told otherwise.
One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Signs you need mastic sealing in Shirburn
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
Typical triggers for a call:
- Old repairs sealed over failed mastic
- Brittle perimeter mastic across a building
- Repeated reactive repairs to the same buildings
- The same joint failures repeated across a portfolio
Site managers at schools like Icknield Community College can fit frame mastic into the summer works.
Comparing quotes
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?

Block-wide mastic in Shirburn
Shirburn is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. At about 40 miles from central London, Shirburn 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.
Historic properties like Adwell House (to the north of Shirburn) show the age of some local stock, where frame mastic must suit soft brick or stone. Landlords with units on estates such as Watlington Industrial Estate (to the south-west of Shirburn) can bring frame, door and external mastic across several units into one programme.
Shirburn is about 6 miles south of Thame, in Oxfordshire. We send applicators to Shirburn for mastic joints. We work across 423 places in Oxfordshire. Oxford is covered too, some 12 miles away.
We take on mastic joints across the OX49 postcode area. Streets here include Watlington Road, Castle Road and Blenheim Road. We also cover Lewknor (1 mile north-east), South Weston (2 miles north), Christmas Common (2 miles south-east), Postcombe (2 miles north) and Howe Hill (3 miles south) for mastic joints. A short drive away, we cover Oxford (12 miles north-west), Didcot (11 miles west), Abingdon-on-Thames (13 miles west), Thame (6 miles north), Henley-on-Thames (9 miles south-east) and Benson (5 miles south-west).

Questions we’re asked in Shirburn
Is Shirburn too far out for you?
Not at all: smaller places are covered as well as towns. 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.
Can you work at a site such as Watlington Industrial Estate, by Shirburn?
Yes. We cover Shirburn and the area around it, including industrial estates, business parks and retail parks such as Watlington Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
