Mastic sealing for commercial buildings in Becontree Heath
Managing agents and housing associations normally need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you have leaks at window and door perimeters and draughts at frames across a block, we can help, on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Becontree Heath, preparation and product choice get the time they need.
In a London area such as Becontree Heath, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time, which is why block-wide programmes make sense.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Share the asbestos register when you send details
- Check sealant joints during planned building inspections
- Plan resealing building by building rather than complaint by complaint
- List the paperwork your organisation requires when you send details
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Water coming in from the roof or rainwater goods
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Do you cover business parks and estates near Becontree Heath, such as Business Centre?
Yes, sites like Business Centre are within our area, along with the rest of Becontree Heath. A few photos and the unit address let us price the work.

Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What about access for upper-floor joints?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
When to call us in Becontree Heath
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
These are often picked up first by site or facilities staff:
- Old repairs sealed over failed mastic
- Draughts at frames across a block
- Window mastic that has split and shrunk
- Movement joints with sealant missing
If you look after a block within reach of Chadwell Heath station, 1.1 miles west of Becontree Heath, frame and balcony mastic can be renewed on one programme.
What your quote should include
