Facade sealing for commercial buildings in Poplar
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, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. If you’re dealing with hard, chalky sealant that no longer flexes and gaps between rainscreen or cladding panels, we can help. Whoever orders the work in Poplar, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Do you need facade sealing in Poplar?
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
Most enquiries start with one or more of the following:
- Draughts around frames and panels
- Hard, chalky sealant that no longer flexes
- Perimeter sealant that has split or peeled away
- Leaks at window and door perimeters
When a college such as New City College, under half a mile to the north of Poplar, builds or refurbishes, the mastic package typically has to fit around students and staff.

- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?

Building and refurbishing in Poplar
The ULEZ covers the whole of Greater London, Poplar included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. The area within 2 miles of Poplar holds a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
When units on a site such as Poplar Business Park (to the east of Poplar) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hotels like London Marriott Hotel Canary Wharf (less than half a mile west of Poplar) rarely close for long, so refurbishment mastic is phased floor by floor.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Joints too narrow for the movement they take, which need redesign
- Installing or repairing glazing systems
- Damp caused by condensation inside the building
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly.
Where we work in Poplar
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Stone and brick facade joints
- Shopfront frames
- Window and door perimeters
- Cladding panel joints
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Keep the sealant details on the building file
- Don’t wait for a second leak before calling
- Add perimeter sealant to planned maintenance checks
- Clear debris that holds water against joints
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Surface by surface
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
Questions we’re asked in Poplar
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for
Is a hospital such as The London Independent Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Can you look at water coming in around a frame?
Yes. We look at the perimeter sealant and tell you whether it has failed. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
How is access to upper-level joints handled?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and we’ll price the work around it.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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 and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Let us know about inductions and permits
- Agree which areas must stay open
- Tell staff and tenants when we’ll be in

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
