About our mastic sealing in Crook Log
Across Crook Log and the rest of Greater London, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. The enquiries we see most involve no planned programme for sealant and open joints in brickwork or panels, on shopfronts below residential blocks, communal entrances and stairwells and balcony and threshold joints. Facilities teams, main contractors and managing agents in Crook Log tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For managing agents in Crook Log, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Different surfaces, different methods
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.
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent.
Work for main contractors and building owners
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Crook Log can form part of a wider programme across Greater London.
When to call us in Crook Log
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
These are often picked up first by site or facilities staff:
- Open joints in brickwork or panels
- The same joint failures repeated across a portfolio
- A mix of products and colours from past repairs
- Draught complaints from residents or tenants
Blocks of flats and mixed-use buildings often cluster around stations such as Bexleyheath station, under half a mile to the north-east of Crook Log, and their window and balcony mastic tends to age at the same rate across a building.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Will CSCS-carded applicators be on site?
- How the existing material will be dealt with
- How they’ll work around occupants
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Keep a record of when each building was resealed
- Have the asbestos survey to hand for older buildings
- Reduce knocks to communal area joints
- Look at the sunniest and most exposed elevations first
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
