What the job involves on each surface
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Materials that need asbestos testing before work
- Failed window or door frames, which need a window contractor
- Misted or failed double-glazed units
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly.
Surfaces we seal
- Window and door perimeters on blocks
- Balcony and threshold joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Have the asbestos survey to hand for older buildings
- Ask residents or tenants to report leaks and draughts early
- Plan resealing building by building rather than complaint by complaint
- Reduce knocks to communal area joints
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use.

- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.

Advice
Planned mastic for Brightwell-cum-Sotwell portfolios
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Brightwell-cum-Sotwell lies roughly 46 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
If you’re responsible for a building such as Church of St James, frame and door mastic needs the same attention as any other property. For owners of several units at places like Hithercroft Industrial Estate, 1.5 miles to the south-east of Brightwell-cum-Sotwell, one programme can deal with frame and external mastic across the lot. Blocks of flats and mixed-use buildings often cluster around stations such as Cholsey station, 3.1 miles south of Brightwell-cum-Sotwell, and their window and balcony mastic tends to age at the same rate across a building.

Why deal with it now?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. For buildings around smaller places like Brightwell-cum-Sotwell, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
