How we handle commercial sealant contractors in Greenwich
Inside a commercial building, sealant does a lot of quiet work: 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. We deal with internal and external sealant joints alike. Most enquiries involve movement joints packed with grit and debris and untidy joints in a reception, shop floor or lobby, across floor and threshold joints, movement joints in walls and floors and kitchen worktops and splashbacks. A single leaking joint is often how a building in Greenwich first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A lot of what we do in Greenwich is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
Buildings in a London area such as Greenwich rarely close for maintenance: 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.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

After the work
After handover, a little attention goes a long way:
- Have extract fans checked so wet areas dry out
- Keep barriers up until the new sealant has cured
- Note dates and locations of sealant work for future planning
- Keep abrasive pads and scrapers off resealed joints
Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early, especially on exposed elevations and in washrooms. If anything looks wrong, call 01277 525 020 or email drawings and photos with a photo.
Sealant installed at the same time usually fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We’ll tell you which sealant joints need doing first and which can wait.

When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Faulty windows rather than failed perimeter sealant
- Suspect materials that need testing and specialist removal
- Structural cracks or movement the joints weren’t designed for
If you are not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.
Joints and surfaces we work on

Why it’s worth doing now in Greenwich
Patching the worst lengths can be the right call on a tight budget. If the rest of the bead is the same age and product, though, it’s usually close behind, so access and set-up end up being paid for twice. We can price both options so you can decide on the facts. Failed sealant in a building in Greenwich can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What affects the price in Greenwich
We price every job individually. The main factors are:
- Location, for remote and island sites
- Joint width, depth and condition
- How much existing material needs removing
- Site requirements such as inductions and permits
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- How the joints are reached, and at what height
- The site address and postcode
- When you need the work done
- Specification clauses that apply
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Working on commercial sites near Greenwich
Less than 3 miles from Greenwich there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies. Greenwich has four care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound; colours can be chosen to suit the interior.
Shops and cafés around stations like Maze Hill station (under half a mile north-east of Greenwich) trade from early, so work is timed around them. Sites a few miles apart, such as Greenwich Centre Business Park and Brookmarsh Industrial Estate, can share one programme and one point of contact. On a business park such as Greenwich Centre Business Park, 0.7 miles to the west of Greenwich, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Diagnose, treat, sign off
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. All of Greater London is in the ULEZ, and kerbside space in Greenwich can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
- Warn occupants and staff about the work

Related advice
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
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.
Questions we’re asked in Greenwich
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Do you cover business parks and estates near Greenwich, such as Greenwich Centre Business Park?
Yes, sites like Greenwich Centre Business Park are within our area, along with the rest of Greenwich. Photos and a short description are enough for a first look.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.
What guarantee do you give on resealing?
The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.
Can you take on work for an FM or managing agent?
Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. We can work to your instruction process and site rules.
