Mastic sealing across Charlwood
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Common problems we fix in Charlwood
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.
Look out for the following:
- Brittle perimeter mastic across a building
- Damp patches beside frames
- The same joint failures repeated across a portfolio
- Open joints in brickwork or panels
Churches, halls and community buildings such as Church of St Nicholas are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What to look for in a quote
- The terms of the workmanship guarantee
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will failed sealant be removed rather than covered?
- Which product they’ll use, and why it suits the joint
Mastic sealing in Charlwood, 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 if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you have leaks at window and door perimeters and failed external movement joints, we can put it right, on shopfronts below residential blocks, window and door perimeters on blocks and external wall and movement joints alike. A single leaking joint is often how a building in Charlwood first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as Charlwood 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 is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Our process
When we get to site, 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 any cutting starts, and the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Jobs in and around smaller places like Charlwood are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- 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 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.
Getting the site ready
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached

Blocks and managed buildings in Charlwood
Central London is about 24 miles from Charlwood. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Buildings close to stations like Ifield station (2.8 miles south of Charlwood) are often flats over shops, with frame mastic to keep sound. Site managers at schools like Charlwood Village Primary School can fit frame mastic into the summer works.

Your questions answered
Is Charlwood too small for you to travel to?
Not at all. Charlwood is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you quote for a block close to Ifield station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Misted or failed double-glazed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Substrate edges that need repairing first
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
What we seal
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints
Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Make mastic part of routine maintenance checks
- Track which buildings were done and when
- Ask residents or tenants to report leaks and draughts early
- Have the asbestos survey to hand for older buildings
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.

Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
