Questions we are asked in North Cray
Can you take on a job at a hospital such as Queen Mary's Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you plan work around the academic year at somewhere like University of Greenwich Avery Hill Campus?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Will rain stop the work?
Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.
Do you provide access for facade work?
We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
How we handle facade sealing in North Cray
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have failed sealant on precast panel joints and facade joints cracked through the middle, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in North Cray is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in a London area such as North Cray 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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Mastic packages on North Cray sites
As part of Greater London, North Cray is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are a number of hotels within about 2 miles of North Cray. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
University estates such as University of Greenwich Avery Hill Campus, 2.8 miles to the west of North Cray, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When a school such as Royal Park Primary Academy is extended or refurbished, the mastic package is often squeezed into the holidays.
North Cray is about 2 miles east of Sidcup, in Greater London. We send applicators to North Cray for facade joints. We work across 764 places in Greater London, from busy centres to rural villages. There’s a separate page for London, about 11 miles away.
Work on facade joints is covered throughout DA14, whatever the building. We cover commercial and managed buildings on Water Lane, North Cray Road and Leafield Lane and the roads nearby. We also cover Bexley (1 mile north), Coldblow (1 mile north-east), Ruxley (1 mile south), Blendon (1 mile north-west) and Joyden's Wood (1 mile east).

Around North Cray
We work on buildings around Foots Cray Meadows, Cleeve Park School and The White Cross pub and the streets around them. For rail, the closest station is Albany Park station, roughly 0.6 miles north-west of the centre. A little further out are Broadway Shopping Centre (1.7 miles north) and Bexley Hospital (1.8 miles north). Not far away are Wansunt Pit and Summer Hill.
Surface by surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a job in North Cray, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out 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.
- The finished joints are checked with you.
Getting the site ready
- Arrange parking or a loading space
- Send any specification or drawings in advance
- Clear stock, furniture or equipment away from the joints

Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Inspect facade joints on a regular cycle
- Combine resealing with other works that need access
- Insist on a full cut-out when joints are renewed
- Keep pressure washers away from fresh sealant
Keep a note of which product went in and when. Future work can then match the product and colour without guesswork.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Arranging specialist high-level access, which is planned with the client
- Damaged frames that need replacing
- Replacing glass or failed glazing units
If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Joints and surfaces we work on
- Cladding panel joints
- Shopfront frames
- Window and door perimeters
- Stone and brick facade joints
- Coping and flashing joints
- Perimeter joints where frames meet the structure
Doing it in-house
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.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What we’re called out for in North Cray
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back.
Clients usually get in touch after noticing one or more of the following:
- Leaks at window and door perimeters
- Perimeter sealant that has split or peeled away
- Failed sealant on precast panel joints
- Discoloured or dirty facade joints
For a contractor working at a hospital such as Queen Mary's Hospital, 1.8 miles south-west of North Cray, perimeter and facade sealing is planned around patients and deliveries.
