Surface by surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach, which matters when environmental health officers look at a kitchen. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
Commercial sealant contractors in New Eltham
On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. Most enquiries involve damp patches where an external joint has failed and shrunken sealant along kitchen worktops and splashbacks, across floor and threshold joints, washrooms and tea points and external facade joints. For commercial sealant work in New Eltham, you deal with one contact from quote to sign-off, whether it’s one building or several.
Multi-site clients with buildings in and around New Eltham can put several sites on one programme, with one quote format and one point of contact.
In London, most commercial sealant work happens in buildings that stay open: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us, and where a brand finish matters, the sealant colour is agreed first.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For a job in New Eltham, access comes first. Send the building rules and access times with your enquiry.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Preparing the site
- Move anything stored against the joints
- Send any specification or drawings in advance
- Tell us which areas need to stay in use
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Common problems we fix in New Eltham
If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. It’s one of the commonest faults we find on earlier work.
It’s worth sending us details if you spot any of the following:
- Wall and floor joints that have lost their seal
- Greasy, split joints in a kitchen or tea point
- Damp patches where an external joint has failed
- Messy, uneven beads from earlier work that let the building down
If you run an office at a site such as Green Lane Business Park (under half a mile west of New Eltham), the sealant at reception desks, tea points and frames ages with each fit-out.
Before you book anyone

- How they’ll work around occupants
- Their approach to joint depth and backing
- What level of public liability insurance do they hold?
What New Eltham’s businesses ask us to seal
New Eltham has several hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We fit into those systems and phase the work so the building keeps operating.
Offices and shops close to stations such as New Eltham station (to the north-east of New Eltham) tend to be busy all day, so sealant work is planned around opening hours. If you have premises on more than one site, say at Green Lane Business Park and Chiltonian Industrial Estate, one contractor and one quote can cover both.

What else we do in New Eltham
Cost factors for sealant joints
Each job is priced on its own details. The main factors are:
- How much there is to seal
- Site requirements such as inductions and permits
- Phasing around occupants
- Whether old sealant has to be cut out first
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Sending details for a quote
However big the job, these details speed things up:
- Any specification or named product
- Your programme or deadline
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Aftercare for building managers
For the best life from the joints:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Make sure ventilation in wet areas is switched on and working
- Keep a record of which joints were resealed and when
- Keep barriers up until the new sealant has cured
Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer. It’s worth having fans checked while the sealant is fresh.
Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.
Your questions answered
Is Green Lane Business Park, near New Eltham, within your area?
Yes. We cover New Eltham and the area around it, including industrial estates, business parks and retail parks such as Green Lane Business Park. A few photographs and the unit address let us price the work.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you take on work for an FM or managing agent?
Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. Tell us how you issue work and we will fit in.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
What do you need from us to quote?
Start with whatever information is to hand. We follow up with questions or a visit where needed.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
