Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Facade sealing in Three Mills, done properly
Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. If you are dealing with air leaks through failed facade joints and perimeter sealant that has split or peeled away, we can put it right. Whoever orders the work in Three Mills, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Every London site, Three Mills included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we’ll arrange a return visit.

What the job involves on each surface
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Three Mills can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Tell us what induction or permit system the site runs
- Have the specification and drawings to hand

Advice
Do you need facade sealing in Three Mills?
When the sealant tears down its centre, it has normally been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Typical triggers for a call:
- Cladding panel joints that have opened up
- New sealant peeling off old mastic
- Leaks at window and door perimeters
- Failed seals around shopfront and entrance frames
Projects at colleges like Onelab College (to the south-west of Three Mills) tend to run to term dates, so the mastic is planned tightly.

FAQs: Three Mills
Does your area include sites such as Crescent Court Business Centre, near Three Mills?
Yes. Estates, retail parks and business parks around Three Mills, Crescent Court Business Centre among them, are all within reach. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is a hospital such as Mile End Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can ring 01277 525 020 or email a schedule or drawings to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll be honest about which it is.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What will the job cost?
There isn’t a price list, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.
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 and the faces are cleaned before resealing. That is what makes the new joint last.
New build and refits around Three Mills
A 2-mile radius around Three Mills takes in plenty of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Site traffic in Three Mills falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in.
On a healthcare site such as Mile End Hospital, which lies west of Three Mills, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. New units and refits on sites such as Crescent Court Business Centre (under half a mile south-east of Three Mills) need their panel and perimeter joints sealed to the specification.

Maintenance after handover
Once the work is signed off, these steps help:
- Plan facade sealing alongside redecoration
- Inspect facade joints on a regular cycle
- Investigate damp beside windows promptly
- Clear debris that holds water against joints
Following storms, look inside for damp or staining near frames. An early report normally means a small reseal rather than a bigger repair.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones inside the building.
