About our mastic sealing in Bermondsey
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you have repeated reactive repairs to the same buildings and damp patches beside frames, we can help, on communal kitchens and washrooms, window and door perimeters on blocks and communal entrances and stairwells alike. For commercial sealant work in Bermondsey, you deal with one contact from quote to sign-off, whether it’s one building or several.
In a London area such as Bermondsey, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
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.

What sets the cost
What shapes the price:
- Location, for remote and island sites
- Joint width, depth and condition
- How accessible the joints are
- How much there is to seal
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- Any dates the work must fit around
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
- Rough lengths or quantities, or drawings if you have them
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Common problems we fix in Bermondsey
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
Typical triggers for a call:
- Mastic failing across several blocks on an estate
- Draught complaints from residents or tenants
- Communal area joints that look neglected
- No planned programme for sealant
If you are responsible for a building such as St Mary Magdalen Bermondsey, frame and door mastic needs the same attention as any other property.
Questions to ask before you book
- Proof of insurance
- How joint depth will be controlled
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
Mastic sealing in Bermondsey: the local picture
Two care or nursing homes sit less than 2 miles from Bermondsey. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. Our programme follows the access you agree with residents.
Buildings close to stations like London Bridge station (0.7 miles north-west of Bermondsey) are often flats over shops, with frame mastic to keep sound. For a school such as Boutcher Church of England Primary School, perimeter mastic on windows and doors is a holiday job.

Common questions from Bermondsey clients
Can you work in a care home near Bermondsey with residents in?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
What do you charge?
Every job gets its own fixed quote. To get one, ring 01277 525 020 or email us.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to phone 01277 525 020 or email the details over.

Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. In Bermondsey, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Looking after the joints
For the best life from the joints:
- Group repairs into a planned programme
- Make mastic part of routine maintenance checks
- Keep bins and bikes away from communal door frames
- Encourage occupiers to report problems at frames
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
