How we handle mastic sealing in Cogges
Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks, and the failures we’re asked to look at most are leaks at window and door perimeters and occupiers reporting cold air round windows. Most enquiries from Cogges start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In a smaller place such as Cogges, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
Questions we’re asked in Cogges
Can you work at a site such as Station Lane Industrial Estate Avenue Four, by Cogges?
Yes. We cover Cogges and the area around it, including industrial estates, business parks and retail parks such as Station Lane Industrial Estate Avenue Four. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Cogges off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Do you do block-wide mastic programmes?
We can. We survey and price each building, then work through them in order, and the programme can start with the worst.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Broken glass or failed sealed units
- Asbestos-containing sealant, which we don’t remove
- Leaks from above rather than through a joint
If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.
What we seal
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
Should maintenance staff do it?
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For owners and agents in Cogges
Central London is about 62 miles from Cogges. Within reach of London, blocks run by agents and associations are common around stations. Cogges sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
Landlords with units on estates such as Station Lane Industrial Estate Avenue Four, less than half a mile to the south of Cogges, can bring frame, door and external mastic across several units into one programme. Blocks of flats and mixed-use buildings often cluster around stations such as Finstock station, 4.8 miles north of Cogges, and their window and balcony mastic tends to age at the same rate across a building.
Cogges is about 1 mile east of Witney, in Oxfordshire. Any commercial site in Cogges is covered, for single jobs and planned programmes alike. 423 places across Oxfordshire fall within our area, Cogges among them. For work in that direction, see our Oxford page, about 11 miles away.
Business premises anywhere in OX28 and OX29 are within our area. We cover commercial and managed buildings on Mead Lane, Puck Lane and Manor Road. Cogges sits on or close to the A4095, useful when we plan access and materials. Close to Cogges, our area also takes in Witney (1 mile west), Madley Park (1 mile north-east), High Cogges (1 mile east), Ducklington (1 mile south) and South Leigh (2 miles east). Bigger towns within reach include Oxford (11 miles east), Abingdon-on-Thames (11 miles south-east), Carterton (5 miles west), Wantage (13 miles south), Grove (12 miles south) and Faringdon (10 miles south-west).
What’s near Cogges
We work on buildings around The Griffin Inn, The Henry Box School and Wood Green School and the streets around them. The closest station to Cogges is Finstock station, about 4.8 miles north. Other landmarks nearby include Cogges Manor Farm Museum (less than half a mile north-east).
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Make mastic part of routine maintenance checks
- Ask residents or tenants to report leaks and draughts early
- Mention RAMS, insurance or CSCS requirements up front
- Check the asbestos register before any old mastic is disturbed
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
Signs you need mastic sealing in Cogges
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.
Most enquiries start with one or more of the following:
- No planned programme for sealant
- A mix of products and colours from past repairs
- Occupiers reporting cold air round windows
- Failed external movement joints
For a school such as The Blake Church of England Primary School, perimeter mastic on windows and doors is a holiday job.
