Cost factors for facade joints
Your fixed quote is built from the real scope. It allows for:
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
- The size and state of each joint
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- The site address and postcode
- Your programme or deadline
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Facade sealing in Canonbury
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, and we’ll fit the work around it. The enquiries we see most involve damp patches beside frames after rain and discoloured or dirty facade joints, on perimeter joints where frames meet the structure, window and door perimeters and shopfront frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Canonbury, preparation and product choice get the time they need.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Questions we’re asked in Canonbury
Is a hospital such as Moorfields Eye Hospital (City Road campus) somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you take on jobs in Canonbury where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What will the job cost?
Every job gets its own fixed quote. For yours, phone 01277 525 020 or email the details over with a description of the work.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Inspect facade joints on a regular cycle
- Keep the sealant details on the building file
- Confirm the survey covers external sealants in older buildings
- Brief window cleaners about newly sealed joints
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
How a job runs
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Confirm the product named in the specification
- Move anything stored against the joints
- Warn occupants and staff about the work

What happens if it’s left?
Patch repairs over old sealant tend to come back. 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. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- Failed material removed, not covered up
- Colours confirmed for the specified product
