Mastic sealing across Leigh
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle mastic sealing in Leigh
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you’re dealing with estate-wide sealant that is simply worn out and window mastic that has split and shrunk, we can help, whatever the surface. A single leaking joint is often how a building in Leigh 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.
In and around smaller places like Leigh, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

- The size and state of each joint
- Location, for remote and island sites
- How much existing material needs removing
- Site requirements such as inductions and permits
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Questions about Leigh
Can you quote for a block close to Leigh (Kent) station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Will you price a mastic programme across our Leigh portfolio?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Can people stay in the building while you reseal?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Block-wide mastic in Leigh
Leigh is about 25 miles from central London. Managed blocks of flats are a big part of commuter-belt property. Leigh is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Blocks of flats and mixed-use buildings often cluster around stations such as Leigh (Kent) station (under half a mile west of Leigh) and their window and balcony mastic tends to age at the same rate across a building. Historic properties like Penshurst Place, 2 miles to the south-west of Leigh, show the age of some local stock, where frame mastic must suit soft brick or stone.
Leigh is about 3 miles west of Tonbridge, in Kent. If you’re looking for mastic sealing in Leigh, we can help. We work across 931 places in Kent, large and small. For work in that direction, see our London page (25 miles or so).
Commercial sites across TN11 are covered for mastic joints. For a building on High Street, Green View Avenue and The Green or nearby, send details and we will quote for mastic joints. We also cover Lower Haysden (1 mile east), Printstile (2 miles south), Bidborough (2 miles south-east), Tonbridge (3 miles east) and Stockland Green (3 miles south) for mastic joints. Nearby towns on our patch include Maidstone (14 miles east), Sevenoaks (6 miles north), Royal Tunbridge Wells (5 miles south-east), Swanley (14 miles north), Kings Hill (10 miles north-east) and Foley Park (15 miles north-east).

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Failed window or door frames, which need a window contractor
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Surfaces we seal
- Communal kitchens and washrooms
- Balcony and threshold joints
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
What we are called out for in Leigh
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.
Typical triggers for a call:
- Worn sealant at communal door frames
- Damp patches beside frames
- Occupiers reporting cold air round windows
- The same joint failures repeated across a portfolio
If your remit includes a building such as Leigh Primary School, frame and door mastic can be programmed for the holidays.
What your quote should include
- The named product and why it was chosen
- What site paperwork they can supply
- Health and safety accreditation such as CHAS
- Their approach to joint depth and backing

Communal areas
We keep entrances and stairs open throughout. Work is planned in sections.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
