Mastic sealing in Newington Butts
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. If you are dealing with no planned programme for sealant and damaged joints in communal entrances and corridors, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Newington Butts is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
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, which is why block-wide programmes make sense.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How a job runs
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. In Newington Butts, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- 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.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Confirm the product named in the specification
- Warn occupants and staff about the work
- Tell us your opening times and when work is allowed

Looking after buildings in and around Newington Butts
The 2 miles around Newington Butts include two care or nursing homes. Owners of care premises can bring window and door mastic into a phased programme planned around the home. In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. Our programme follows the access you agree with residents.
Site managers at schools like London College of Communication can fit frame mastic into the summer works. Churches, halls and community buildings such as Metropolitan Tabernacle are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Why act early in Newington Butts
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

What else we do in Newington Butts
How the job changes by surface
Estate-wide resealing programmes
Priority order can follow condition, complaints or your maintenance plan. You get one fixed quote per building or for the whole estate.
Tenement and older buildings
Natural stone can be marked by the wrong sealant and we choose accordingly.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Mention RAMS, insurance or CSCS requirements up front
- Have the asbestos survey to hand for older buildings
- Keep bins and bikes away from communal door frames
- Prioritise elevations facing the weather
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
What we are called out for in Newington Butts
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 and fails early.
It’s worth sending us details if you spot any of the following:
- Occupiers reporting cold air round windows
- No planned programme for sealant
- Mastic failing across several blocks on an estate
- Open joints in brickwork or panels
If you own or manage units on a site such as Southwark Bridge Business Centre, 0.8 miles to the north of Newington Butts, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
