Mastic sealing in Trash Green, done properly
Managing agents and housing associations typically need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you are dealing with old repairs sealed over failed mastic and open joints in brickwork or panels, we can put it right. A single leaking joint is often how a building in Trash Green first comes to us: we look at the rest while we are there and tell you what we find.
For buildings around smaller places like Trash Green, we group work so one trip covers it. Photos of each elevation help us quote accurately.
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’re clear about what is covered before work starts.

Leave it or put it right?
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee. Around Trash Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What you get with us
- Workmanship guaranteed for 12 months
- Clear, fixed quotes
- Fully insured
- Specification-led, product-correct work

Common problems we fix in Trash Green
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.
Typical triggers for a call:
- Damaged joints in communal entrances and corridors
- Damp patches beside frames
- Repeated reactive repairs to the same buildings
- Failed external movement joints
Site managers at schools like Burghfield St Mary's C.E. Primary School can fit frame mastic into the summer works.

Advice
Questions we’re asked in Trash Green
Will you take on work at estates like Theale Lakes Business Park, close to Trash Green?
Yes. Our area takes in Trash Green and its surroundings, with estates and business parks such as Theale Lakes Business Park included. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you quote for a block close to Theale station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Who decides which product is used?
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.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Surface by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.
