How we handle mastic sealing in Parsons Green
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. The enquiries we see most involve leaks at window and door perimeters and occupiers reporting cold air round windows, on shopfronts below residential blocks, communal kitchens and washrooms and external wall and movement joints. One point of contact handles commercial sealant work in Parsons Green from the first photos to the final walk-round, whether it’s one building or several.
For managing agents in Parsons Green, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common problems we fix in Parsons Green
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Things that normally lead to an enquiry:
- Patchy repairs in mismatched sealant
- No planned programme for sealant
- Water getting in round frames after rain
- Movement joints with sealant missing
Student accommodation around universities such as BIMM University (less than half a mile north of Parsons Green) is normally managed block by block, which suits a planned mastic programme.

Tenement and older buildings
Natural stone can be marked by the wrong sealant and we choose accordingly.
External movement joints
Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.
When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Failed window or door frames, which need a window contractor
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove

Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. All of Greater London is in the ULEZ, and kerbside space in Parsons Green can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.

- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.

Advice
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep a record of when each building was resealed
- Protect low-level joints in entrances
- Make mastic part of routine maintenance checks
- Avoid piecemeal callouts where you can
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
Why deal with it now?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. In Parsons Green, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Questions about Parsons Green
Do you work for managing agents with blocks near Imperial Wharf station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you take on jobs in Parsons Green where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it.
Does weather matter for sealant work?
For external joints, 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.
How long does a job like this take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
