Facade sealing in Mile End
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. If you’re dealing with unsightly perimeter sealant on a visible elevation and previous reseals run over old sealant, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Mile End is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email the details over and we will arrange a return visit.

What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Cracked or spalling substrates that need repair before sealing
- Providing access systems for the work
- Movement beyond what any sealant can handle

Owners, agents and contractors
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Aftercare for building managers
For the best life from the joints:
- Avoid patch repairs on failed facade joints
- Combine resealing with other works that need access
- Ask about asbestos in pre-2000 mastic
- Avoid harsh cleaners on facade sealant
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly using a matching sealant.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. In Mile End, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Preparing the site
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Let us know about inductions and permits

Facade sealing around Mile End: points for this area
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Mile End. Deliveries are booked and storage is tight, so mastic materials come in as needed. A good number of hotels sit less than 2 miles from Mile End. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Hotel extensions and refits, at places such as New Globe Hotel, less than half a mile west of Mile End, usually run between busy periods, so the sealing is squeezed into short windows. When a college such as Onelab College, 0.6 miles to the east of Mile End, builds or refurbishes, the mastic package normally has to fit around students and staff. For contractors refurbishing units at places like Bow Triangle Business Centre, which lies east of Mile End, the mastic covers cladding panels, roller-door and window perimeters.
Mile End is about 2 miles east of Whitechapel, in Greater London. Across the E3 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 764 places in Greater London, large and small.
We take on facade joints across the E3, E1 and E14 postcode area, whatever the building. Among the streets we cover are Bow Road, Bale Road and Toby Lane, and sites on any of them can send details for a fixed quote. You’ll find Mile End on or near the A1205.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Different surfaces, different methods
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch.
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed.

Could you schedule work at a campus like Queen Mary University of London for the vacation?

Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Is old mastic on our building likely to contain asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months on every job.
Can you work on upper floors?
That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we’ll plan the work with you.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
