How we handle mastic sealing in Westcombe Park
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on window and door perimeters on blocks, shopfronts below residential blocks and communal entrances and stairwells, and the failures we are asked to look at most are open joints in brickwork or panels and complaints coming in block by block. Most enquiries from Westcombe Park start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building.
Every job we finish is backed by a 12-month workmanship guarantee, in Westcombe Park as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Why us?
- A range of standard colours, depending on the product
- Colour options checked against the specified product
- Products installed to the manufacturer’s instructions
- Failed material removed, not covered up

From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking a few days for most blocks, with larger programmes scheduled building by building. In Westcombe Park, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
What we need from you
- Tell us what induction or permit system the site runs
- Move anything stored against the joints
- Confirm the product named in the specification

Signs you need mastic sealing in Westcombe Park
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Typical triggers for a call:
- Open joints in brickwork or panels
- Water getting in round frames after rain
- Brittle perimeter mastic across a building
- A mix of products and colours from past repairs
Property owners at sites such as Angerstein Business Park, less than half a mile north of Westcombe Park, can have mastic renewed between lettings.

Planned mastic for Westcombe Park portfolios
Westcombe Park has four care or nursing homes no more than 2 miles away. 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.
If your remit includes a building such as Halstow Primary School, frame and door mastic can be programmed for the holidays. Blocks of flats and mixed-use buildings often cluster around stations such as Westcombe Park station (to the north of Westcombe Park) and their window and balcony mastic tends to age at the same rate across a building.

What affects the price in Westcombe Park
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Whether old sealant has to be cut out first
- Distance, for remote addresses
- Whether the work must be split into stages
- Any access equipment needed
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Any dates the work must fit around
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
- Specification clauses that apply
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.
Questions we’re asked in Westcombe Park
Does your area include sites such as Angerstein Business Park, near Westcombe Park?
Yes. Our area takes in Westcombe Park and its surroundings, with estates and business parks such as Angerstein Business Park included. A few photos and the unit address let us price the work.
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
How do you handle work on occupied blocks?
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.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- List the paperwork your organisation requires when you send details
- Have the asbestos survey to hand for older buildings
- Look at the sunniest and most exposed elevations first
- Log resealing dates block by block
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.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
