About our mastic sealing in Poverest
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on shopfronts below residential blocks, communal entrances and stairwells and window and door perimeters on blocks, and the failures we are asked to look at most are leaks at window and door perimeters and patchy repairs in mismatched sealant. A specialist sealant contractor works differently from a general builder: in Poverest, that means joint design, primers and backing rod as standard.
In a London area such as Poverest, 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Poverest as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Common questions from Poverest clients
We manage a building near St Mary Cray station. Can you help?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Do you work in Poverest?
Yes. We cover Poverest, and you can give us a call on 01277 525 020 or email the details over to get started.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Why deal with it now?
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee. 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 work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

When to call us in Poverest
Buildings move with temperature and moisture, 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.
Look out for the following:
- Damaged joints in communal entrances and corridors
- No planned programme for sealant
- Failed external movement joints
- Leaks at window and door perimeters
Buildings close to stations like St Mary Cray station (under half a mile north-east of Poverest) are often flats over shops, with frame mastic to keep sound.
Comparing quotes
- Whether old or failed sealant will be cut out, not overlaid
- Their public liability cover
- How they handle RAMS and site documents
- Will CSCS-carded applicators be on site?
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Plan resealing building by building rather than complaint by complaint
- Keep a record of when each building was resealed
- Check sealant joints during planned building inspections
- Ask residents or tenants to report leaks and draughts early
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.

Give us the hours we can be on site and we’ll schedule to suit.
