When to bring in a specialist
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.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Facade sealing for commercial buildings in St Mary Cray
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. We work on cladding panel joints, stone and brick facade joints and coping and flashing joints, and what we’re called in for most is discoloured or dirty facade joints and cladding panel joints that have opened up. A specialist sealant contractor works differently from a general builder: on jobs in St Mary Cray, preparation and product choice get the time they need.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in St Mary Cray must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Cost factors for facade joints
Each job is priced on its own details. The things that drive the figure:
- The size and state of each joint
- Working within restricted access windows
- Location, for remote and island sites
- Whether old sealant has to be cut out first
A quote for facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- The postcode of the building
- A wide shot and a close-up of the area
- The product your specification calls for
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Plan facade sealing alongside redecoration
- Check the asbestos register before old mastic is disturbed
- Avoid harsh cleaners on facade sealant
- Inspect facade joints on a regular cycle
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.
Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Planning a London job such as one in St Mary Cray starts with access. Send the building rules and access times with your enquiry.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Preparing the site
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions

FAQs: St Mary Cray
Do you take on jobs in St Mary Cray where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Is Halo Business Park, near St Mary Cray, within your area?
Yes. We cover St Mary Cray and the area around it, including industrial estates, business parks and retail parks such as Halo Business Park. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
How do I request a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photographs or drawings if you have them.
What do you charge?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
Do you need facade sealing in St Mary Cray?
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Most enquiries start with one or more of the following:
- Damp patches beside frames after rain
- Failed seals around shopfront and entrance frames
- Sealant pulling away from frames or panels
- Draughts around frames and panels
When units on a site such as Halo Business Park (under half a mile east of St Mary Cray) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Questions to ask before you book
- How joint depth will be controlled
- How long is the guarantee, and what does it include?
- Whether their applicators hold CSCS cards
- Are they CHAS accredited or on Constructionline?
