How we handle facade sealing in Woolwich
Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. If you have water coming in around window frames and facade joints cracked through the middle, we can help. A single leaking joint is often how a building in Woolwich 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.
Construction in a London area such as Woolwich means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Sites and facades in and around Woolwich
Plenty of hotels sit less than 2 miles from Woolwich. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. As part of Greater London, Woolwich is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
When units on a site such as Woolwich Dockyard Industrial Estate, 0.5 miles to the north-west of Woolwich, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. On a campus such as University of East London, which lies north of Woolwich, new teaching buildings and residences are usually built and refurbished around the academic year. Projects at colleges like Shooters Hill Sixth Form College, 1.1 miles south of Woolwich, tend to run to term dates, so the mastic is planned tightly.
Woolwich is about 6 miles south-east of Leyton, in Greater London. If you are looking for facade sealing in Woolwich, we can help, as we do across Greater London. We work across 764 places in Greater London, large and small. Our London page has more on work in that area.

Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

What happens if it’s left?
Topping up a failed joint typically 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. Failed sealant in a building in Woolwich can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
Pricing facade joints depends on how many there are, their condition and the access. Call for a quote.

Keeping the joints sound
Once the work is signed off, these steps help:
- Never let anyone seal over old sealant
- Keep the sealant details on the building file
- Don’t wait for a second leak before calling
- Share access with other external trades
After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. In Woolwich, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Before we start on site

What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Render or concrete edges that have broken away
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Work on the window or framing system itself
If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
What we seal
- Cladding panel joints
- Stone and brick facade joints

Woolwich: questions and answers
Will you plan work around the academic year at somewhere like University of East London?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What will the job cost?
Each job is quoted on its own details. To get one, call the office on 01277 525 020 or email drawings and photos.
