Mastic sealing in Dagenham, done properly
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 if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. Most enquiries involve complaints coming in block by block and open joints in brickwork or panels, on external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks. Whoever orders the work in Dagenham, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and we clear our waste as we work. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Move anything stored against the joints
- Tell staff and tenants when we will be in
- Flag any permit to work we’ll need

Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Failed window or door frames, which need a window contractor
- Substrate edges that need repairing first
- Misted or failed double-glazed units
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think before you book.
What we seal
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- External wall and movement joints
Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Group repairs into a planned programme
- Include mastic in your cyclical inspections
- Prioritise elevations facing the weather
- Ask residents or tenants to report leaks and draughts early
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.

Do you need mastic sealing in Dagenham?
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
Any of the following is a good reason to get the joints checked over:
- A mix of products and colours from past repairs
- Repeated reactive repairs to the same buildings
- Leaks at window and door perimeters
- Open joints in brickwork or panels
Student accommodation around universities such as University of East London (4.7 miles south-west of Dagenham) is typically managed block by block, which suits a planned mastic programme.
