Mastic sealing for businesses in Hither Green
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Start inspections with the most exposed faces
- Log resealing dates block by block
- Encourage occupiers to report problems at frames
- Protect low-level joints in entrances
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
How we handle mastic sealing in Hither Green
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. Most enquiries involve worn sealant at communal door frames and complaints coming in block by block, on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hither Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as Hither Green, 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.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Advice
When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Materials that need asbestos testing before work
- Leaks through the frame itself rather than the perimeter
- Glazing that needs replacing
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

FAQs: Hither Green
Is Chiltonian Industrial Estate, near Hither Green, within your area?
Yes. We cover Hither Green and the area around it, including industrial estates, business parks and retail parks such as Chiltonian Industrial Estate. Photos and a short description are enough for a first look.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Will residents or tenants be disturbed?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
When to call us in Hither Green
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
It’s worth sending us details if you spot any of the following:
- Estate-wide sealant that is simply worn out
- Damaged joints in communal entrances and corridors
- Water getting in round frames after rain
- Patchy repairs in mismatched sealant
Student blocks close to universities like University of Greenwich - Greenwich Campus, 2.1 miles to the north of Hither Green, are easiest to work on between tenancies.
Before you book anyone
- What the guarantee covers, and for how long
- Proof of insurance
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
Why it’s worth doing now in Hither Green
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. In Hither 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.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
