Common questions from Out Elmstead clients
Do you work for managing agents with blocks near Aylesham station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Out Elmstead too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Mastic sealing in Out Elmstead, done properly
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. We work on communal entrances and stairwells, balcony and threshold joints and external wall and movement joints, and what we’re called in for most is damp patches beside frames and draughts at frames across a block. For commercial sealant work in Out Elmstead, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Owners and agents with buildings around smaller places such as Out Elmstead tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
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.

Why deal with it now?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. For buildings around smaller places like Out Elmstead, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Mastic sealing around Out Elmstead: what changes locally
Central London is about 57 miles from Out Elmstead. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first.
Property owners at sites such as CT3 Business Park (1.6 miles east of Out Elmstead) can have mastic renewed between lettings. Trustees of buildings like Church of St Giles can bring frame and external mastic into a planned maintenance list. Schools and community buildings such as Barham Church of England Primary School need frame and external mastic kept sound like any building.

Different surfaces, different methods
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Maintenance after handover
A few simple habits keep the new joints working:
- Keep a record of when each building was resealed
- Plan resealing building by building rather than complaint by complaint
- Share your contractor requirements early
- Start inspections with the most exposed faces
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.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
