Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Mastic sealing in South Malling
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. Most enquiries involve occupiers reporting cold air round windows and cracked, hardened mastic round windows on a block, across communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints. Whoever orders the work in South Malling, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Why it’s worth doing now in South Malling
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What the job involves on each surface
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. Tell us your site hours and access windows and we will plan around them.
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
Maintenance after handover
After handover, a little attention goes a long way:
- Group repairs into a planned programme
- Include mastic in your cyclical inspections
- Protect low-level joints in entrances
- Start inspections with the most exposed faces
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- The size and state of each joint
- Phasing around occupants
- How accessible the joints are
- How much there is to seal
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What we need to price the job
However big the job, these details speed things up:
- The postcode of the building
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or email us.

South Malling: questions and answers
We manage a building near Lewes station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you work at a site such as Riverside Industrial Estate, by South Malling?
Yes. We cover South Malling and the area around it, including industrial estates, business parks and retail parks such as Riverside Industrial Estate. Photos and a short description are enough for a first look.
How do you reach windows on upper floors?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Several jobs near South Malling can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
