How we handle facade sealing in Agar Town
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on stone and brick facade joints, shopfront frames and coping and flashing joints, and the failures we’re asked to look at most are weathered facade joints that have lost their grip and facade joints cracked through the middle. For commercial sealant work in Agar Town, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around Agar Town, as across London, much of the work is refurbishing existing buildings as well as building new ones. 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.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Joints too narrow for the movement they take, which need redesign
- Specialist high-level access methods
- Cracked or spalling substrates that need repair before sealing
If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Should maintenance staff do it?
Redoing a failed joint normally costs more than getting it right at the outset, 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.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
On site: what to expect
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. 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.
- We hand over with our 12-month workmanship guarantee.

Advice
After the work
For the best life from the joints:
- Insist on a full cut-out when joints are renewed
- Combine resealing with other works that need access
- Confirm the survey covers external sealants in older buildings
- Add perimeter sealant to planned maintenance checks
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones behind the facade.
Agar Town: questions and answers
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Is Roman Way Industrial Estate, near Agar Town, within your area?
Yes. We cover Agar Town and the area around it, including industrial estates, business parks and retail parks such as Roman Way Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Do you run new sealant over the existing bead?
No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.
How long does a typical visit take?
It depends on the scope, though a typical visit normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Sites and facades in and around Agar Town
Site traffic in Agar Town falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. Agar Town has plenty of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Hotel extensions and refits, at places such as Happy Vale Hotel, 0.5 miles to the south-west of Agar Town, typically run between busy periods, so the sealing is squeezed into short windows. Extensions at sites like St. Pancras Hospital (to the south of Agar Town) typically sit beside working departments, and the mastic follows strict access rules. New units and refits on sites such as Roman Way Industrial Estate, 0.8 miles to the east of Agar Town, need their panel and perimeter joints sealed to the specification.

Why act early in Agar Town
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
