On a typical commercial building in New Malden, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Around New Malden, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common problems we fix in New Malden
No sealant joint is permanent. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, which is why regular inspection pays.
These are often picked up first by site or facilities staff:
- Movement joints packed with grit and debris
- Water staining near frames, panels or ceilings
- Black mould through washroom sealant that won’t clean off
- Frame sealant that has cracked, shrunk or pulled away
Sites a few miles apart, such as Shannon Commercial Centre and Wyvern Industrial Estate, can share one programme and one point of contact.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
- Will CSCS-carded applicators be on site?
- Their plan for phasing and protecting the area

Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
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.
Why deal with it now?
Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Why appoint us
- CHAS accredited contractor
- Specification-led, product-correct work
- CSCS-carded applicators
- Old sealant cut out, never sealed over

Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from part of a day on a short run of joints to several weeks on a large phased package. 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.
- We start with the evidence: photographs, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close
- Let us know about inductions and permits

Advice
What New Malden’s businesses ask us to seal
Less than 3 miles from New Malden there are at least three named estates and business parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen. There are a good number of hotels within about 2 miles of New Malden. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading.
For tenants and agents on sites such as Shannon Commercial Centre, which lies east of New Malden, office fit-outs, reception joints and window perimeters are the usual sealant work. For a shop at a centre such as Bentall Centre (1.9 miles west of New Malden), tidy joints at counters and displays matter as much as the fixtures.

Looking after the joints
After handover, these steps help:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Act on the first lifting edges rather than waiting
- Look at the sealant around anything that has been moved or replaced
- Keep washroom and kitchen extraction working
We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records, and tell us if a joint we sealed gives trouble within that time.
Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.
Common questions from New Malden clients
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Is Shannon Commercial Centre, near New Malden, within your area?
Yes. Our area takes in New Malden and its surroundings, with estates and business parks such as Shannon Commercial Centre included. Send details of the unit and the work through our quote form for a quick quote.
Do you take on multi-site sealant work?
Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.
Will the building have to shut during the work?
Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing for as long as the cure needs.
What about asbestos in old mastic?
Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes a few hours for one area, or a planned series of visits across a bigger building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you take on work for an FM or managing agent?
Yes. You can send details through our quote form, and tell us what site paperwork you need.
