Construction mastic for Addington sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Allow flexibility for external sealing in damp or cold weather
- Use the product the specification names
- Release areas for mastic once other trades have finished in them
- Note which sealant went where at handover
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.
Construction mastic for commercial buildings in Addington
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. If you have different trades sealing to different standards and frame gaps too wide for sealant alone, we can put it right, on floor and skirting junctions, sanitary and kitchen joints and internal decorators’ caulk alike. For commercial sealant work in Addington, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Addington must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Construction mastic in Addington: the local picture
The ULEZ covers the whole of Greater London, Addington included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Addington takes in several hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Projects at schools like Applegarth Academy work to term dates, so mastic is programmed tightly. On a healthcare site such as Bethlem Royal Hospital, which lies north of Addington, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Addington is about 3 miles south-east of Ashburton, in Greater London. Looking for construction mastic in Addington? We can help, as we do across Greater London. Our Greater London coverage takes in 764 places. Our London page has more on work in that area (10 miles or so).

From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it 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 what induction or permit system the site runs
- Let building users know which areas are affected
- Send your site hours and access windows

When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What sets the cost
To price the job, we consider:
- Location, for remote and island sites
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
- The product specified
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
- The type of building and who uses it
- The site address and postcode
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send photos by email to discuss it first.
Common questions from Addington clients
Do you take on jobs in Addington 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. We allow for the ULEZ, which covers every borough
Can you work at a site such as Vulcan Way Industrial Estate, by Addington?
Yes. We cover Addington and the area around it, including industrial estates, business parks and retail parks such as Vulcan Way Industrial Estate. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Will you stick to the specified products?
We follow the specified sealant, and we will raise it if something in it doesn’t suit the joint. Product standards such as BS EN 15651 are often named in specifications.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

When to call us in Addington
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.
It’s worth sending us details if you spot any of the following:
- Inconsistent sealant finishes from plot to plot
- Existing joints on a refurb that need cutting out and resealing
- Early adhesion failures on new external joints
- Snag items on joints that need redoing before handover
Older buildings in the area around Addington, such as Addington Palace, 0.4 miles to the west of Addington, need care when sealed: the product has to suit soft or historic materials.
Before you book anyone
- Who will actually carry out the work
- Which product they’ll use, and why it suits the joint
- How joint depth will be controlled
- Their public liability cover
Why act early in Addington
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. 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.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why appoint us
- Failed material removed, not covered up
- Commercial sealant work since 2005
