About our mastic sealing in Lower Green
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on communal kitchens and washrooms, external wall and movement joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are open joints in brickwork or panels and repeated reactive repairs to the same buildings. Most enquiries from Lower Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
In and around smaller places like Lower Green, 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.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email us and we’ll come back to it.

Planned mastic for Lower Green portfolios
Lower Green is about 35 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Lower Green sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Churches, halls and community buildings such as Church of St John the Evangelist are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Landlords with units on estates such as Bell Farm Industrial Park (to the west of Lower Green) can bring frame, door and external mastic across several units into one programme.
Lower Green is in Essex. Anywhere in CB11, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 644 places across Essex fall within our area, Lower Green among them. Our London page has more on work in that area.

What happens if it’s left?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Halls, stores and units around places like Lower Green may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Different surfaces, different methods
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.
On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a building around Lower Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Warn occupants and staff about the work
- Make sure the joints can be reached
- Have the specification and drawings to hand
Getting a fixed quote

Looking after the joints
After handover, these steps help:
- Start inspections with the most exposed faces
- Reduce knocks to communal area joints
- Plan resealing building by building rather than complaint by complaint
- Keep a record of when each building was resealed
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Asbestos-containing sealant, which we don’t remove
- Substrate edges that need repairing first
- Frames that are rotten, warped or broken
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
What we seal
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- External wall and movement joints
- Shopfronts below residential blocks
Your questions answered
Do you take on block-wide or estate-wide mastic work in Lower Green?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Will you take on work at estates like Bell Farm Industrial Park, close to Lower Green?
Yes. Estates, retail parks and business parks around Lower Green, Bell Farm Industrial Park among them, are all within reach. A few photographs and the unit address let us price the work.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so there are no surprises.
How many days will you need on site?
That varies with the scale of the job, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
