Mastic sealing in Winchmore Hill
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. We work on communal entrances and stairwells, window and door perimeters on blocks and shopfronts below residential blocks, and the usual reasons a site gets in touch are worn sealant at communal door frames and movement joints with sealant missing. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Winchmore Hill, that means joint design, primers and backing rod as standard.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we’ll come back to it.

Commercial clients in Winchmore Hill
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Plan resealing building by building rather than complaint by complaint
- Keep a record of when each building was resealed
- Encourage occupiers to report problems at frames
- Include mastic in your cyclical inspections
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.

Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a few days for most blocks, with larger programmes scheduled building by building. In Winchmore Hill, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Point out parking and an unloading spot
- Have the specification and drawings to hand
