About our mastic sealing in Wanstead
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. The enquiries we see most involve damp patches beside frames and cracked, hardened mastic round windows on a block, on balcony and threshold joints, communal entrances and stairwells and window and door perimeters on blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Wanstead, preparation and product choice get the time they need.
In a London area such as Wanstead, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time, which is why block-wide programmes make sense.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

How the job changes by surface
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Commercial and mixed-use buildings
Commercial occupiers normally stay open during the work, so we plan around them.
Signs you need mastic sealing in Wanstead
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.
It’s worth sending us details if you spot any of the following:
- Repeated reactive repairs to the same buildings
- A mix of products and colours from past repairs
- Damaged joints in communal entrances and corridors
- Draught complaints from residents or tenants
If your remit includes a building such as Wanstead Church School, frame and door mastic can be programmed for the holidays.
Questions to ask before you book
- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Planning a London job such as one in Wanstead starts with access. Send the building rules and access times with your enquiry.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Have the specification and drawings to hand
- Point out parking and an unloading spot
- Move anything stored against the joints

Advice
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Make mastic part of routine maintenance checks
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
- Keep a record of when each building was resealed
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
Why it’s worth doing now in Wanstead
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. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why appoint us
- Specification-led, product-correct work
- One contact handling all your sites
- Clear, fixed quotes
- Failed material removed, not covered up
