Mastic sealing in New Addington, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you’re dealing with a mix of products and colours from past repairs and draught complaints from residents or tenants, we can put it right, on communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks alike. One point of contact handles commercial sealant work in New Addington from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Across Greater London, New Addington included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

New Addington: questions and answers
Do you work for managing agents with blocks near Hayes (Kent) station?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Do you cover business parks and estates near New Addington, such as Vulcan Way Industrial Estate?
Yes, sites like Vulcan Way Industrial Estate are within our area, along with the rest of New Addington. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
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.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Prioritise elevations facing the weather
- Share your contractor requirements early
- Log resealing dates block by block
- Check the asbestos register before any old mastic is disturbed
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
One failed perimeter normally 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.
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- Access and working height
- Backing rod, priming and other preparation
- Location, for remote and island sites
- The product specified
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.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Clear photos of the problem areas
- The postcode of the building
- Whether the building will be occupied during the work
- Your programme or deadline
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or use the quote form.

From enquiry to sign-off
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. In New Addington, 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.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected
- Agree which areas must stay open

Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
