Construction mastic in Anerley: the local picture
As part of Greater London, Anerley is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. The area within 2 miles of Anerley holds several hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
For contractors refurbishing units at places like Franklin Industrial Estate, 0.6 miles east of Anerley, the mastic covers cladding panels, roller-door and window perimeters. Work at a hotel such as Astra Palace Hotel (0.9 miles north of Anerley) tends to be programmed around bookings, mastic included.
Anerley is about 2 miles north-east of Thornton Heath, in Greater London. Anywhere in SE20, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

How the job changes by surface
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. A kitchen-suitable sealant is used and hygienic or food-safe grades wherever food contact is possible.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
Signs you need construction mastic in Anerley
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Clients usually get in touch after noticing one or more of the following:
- Existing joints on a refurb that need cutting out and resealing
- A long mastic snag list close to completion
- Cracks opening in caulked internal joints
- A mastic package split between trades with no clear owner
Extensions at sites like British Home & Hospital for Incurables (1.8 miles west of Anerley) typically sit beside working departments, and the mastic follows strict access rules.
What to look for in a quote
- Who will actually carry out the work
- The named product and why it was chosen
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid

Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Building owners, agents and FMs in Anerley
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
Questions we are asked in Anerley
Is a hospital such as British Home & Hospital for Incurables somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you take on jobs in Anerley where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
What does a mastic package normally include?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Is colour matching possible?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Do you do fire-rated sealing on new builds?
Where it’s specified, yes. We’ll flag if the detail needs a different product.
After the work
To get the most from the new sealant:
- Protect sealed areas from following trades
- Get the mastic subcontractor involved early in the programme
- Don’t force external sealing on a damp or frosty day
- Flag uneven or tapered frame gaps early
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed
