About our facade sealing in Shadwell
A good facade joint depends on design as much as product. 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. If you have facade joints cracked through the middle and cladding panel joints that have opened up, we can put it right. A specialist sealant contractor works differently from a general builder: in Shadwell, that means joint design, primers and backing rod as standard.
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.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or email us and we will arrange a return visit.

Facades, frames and programmes in Shadwell
Site traffic in Shadwell 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. Plenty of hotels sit less than 2 miles from Shadwell. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For a contractor at a hotel such as Dockside Hotel, which lies north-west of Shadwell, the mastic often has to be finished before a reopening date. Units on estates such as Princes Court Business Centre (0.5 miles west of Shadwell) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a campus such as University of Cumbria in London, 1 mile east of Shadwell, new teaching buildings and residences are usually built and refurbished around the academic year.
Shadwell is about 1 mile south-east of Whitechapel, in Greater London. We cover commercial sites throughout Shadwell, for single jobs and planned programmes alike. Across Greater London, 764 places are covered, Shadwell among them.

Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. For a job in Shadwell, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- 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
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000
- Tell staff and tenants when we’ll be in

Quoting for work in Shadwell
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- Joint width, depth and condition
- Access and working height
- Working within restricted access windows
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Approximate linear metres or a joint schedule
- When you need the work done
- The asbestos register, for older buildings
- The product your specification calls for
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email drawings and photos.
Questions we’re asked in Shadwell
Can you take on a job at a hospital such as The London Independent Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Could you schedule work at a campus like University of Cumbria in London for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Ask about asbestos in pre-2000 mastic
- Plan facade sealing alongside redecoration
- Inspect facade joints on a regular cycle
- Report water ingress at frames as soon as it shows
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Damaged frames that need replacing
- Installing or repairing glazing systems
- Water getting in through cracked render or porous masonry
If you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer.
