Facade sealing in Greenwich: the local picture
As part of Greater London, Greenwich is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. Plenty of hotels sit less than 2 miles from Greenwich. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For contractors at a college like Bellerbys College London (1 mile west of Greenwich), perimeters and internal sealant are timed for the holidays. On a campus such as University of Greenwich, which lies north-west of Greenwich, new teaching buildings and residences are usually built and refurbished around the academic year. When units on a site such as Greenwich Centre Business Park, 0.7 miles west of Greenwich, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Greenwich is about 4 miles east of London, in Greater London. Greenwich sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Greater London, 764 places are covered, including Greenwich.
Commercial sites across SE10, SE3 and SE8 are covered. We cover commercial and managed buildings on Cade Road, Webb Road and Creek Road. With the A2203 and A2211 nearby, Greenwich is easy to get to with materials and equipment. Just outside Greenwich, we also work in Maze Hill (1 mile north-east), Vanbrugh Park Estate (1 mile east), Blackheath (1 mile south-east), Westcombe Park (1 mile east) and Isle of Dogs (1 mile north-west). Bigger towns within reach include London (4 miles west), City of Westminster (7 miles west), Marylebone (7 miles west), Kensington (9 miles west), St Pancras (6 miles north-west) and Shoreditch (5 miles north-west).
Landmarks near Greenwich
We work on buildings around The Plume of Feathers pub, John Roan School and Royal School of Naval Architecture and Marine Engineering and the streets around them. You will also find Island Gardens (0.6 miles north-west) and St. Paul's (1.1 miles west). Greenwich has its own railway station: Maze Hill station. A little further out are Greenwich Castle (less than half a mile south-west) and Greenwich District Hospital (0.5 miles north-east). For a walk, there’s Tower Hill and Creekside Discovery Centre.
Facade sealing in Greenwich
Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. If you are dealing with facade joints cracked through the middle and new sealant peeling off old mastic, we can help. Most enquiries from Greenwich start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Quoting for work in Greenwich
A fixed quote reflects the actual work. It takes account of:
- Backing rod, priming and other preparation
- Working within restricted access windows
- The site’s rules and procedures
- How accessible the joints are
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- The type of building and who uses it
- Where the site is, with the postcode
- Any specification or named product
- The asbestos register, for older buildings
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Questions we are asked in Greenwich
Will you plan work around the academic year at somewhere like University of Greenwich?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Greenwich Centre Business Park, near Greenwich, within your area?
Yes, sites like Greenwich Centre Business Park are within our area, along with the rest of Greenwich. Send details of the unit and the work through our quote form for a quick quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How do I request a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Is colour matching possible?
That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
How much does the work cost?
There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
Leave it or put it right?
Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Getting scaffold, permits or access booked in Greenwich takes effort, so it makes sense to deal with every failing joint while access is in place.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Installing or repairing glazing systems
- Arranging specialist high-level access, which is planned with the client
- Render or concrete edges that have broken away
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.
What we seal
- Shopfront frames
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Coping and flashing joints
- Window and door perimeters
- Stone and brick facade joints
How a job runs
Occupied buildings need a little choreography. 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. In Greenwich, 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.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Let us know about inductions and permits
- Clear stock, furniture or equipment away from the joints

For managing agents and facilities managers
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Greenwich. One quote can cover more than one site, so there’s one set of paperwork to deal with.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
