Mastic sealing for commercial buildings in Silvertown
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. If you are dealing with repeated reactive repairs to the same buildings and leaks at window and door perimeters, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Silvertown tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What the job involves on each surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.
Silvertown: questions and answers
Will you take on a block within reach of Custom House station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Can you work in a care home near Silvertown with residents in?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.

There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Cost factors for mastic joints
Each job is priced on its own details. The main factors are:
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Phasing around occupants
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- Specification clauses that apply
- Whether an asbestos survey exists
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Why act early in Silvertown
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes and those cost far more to put right. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

Related advice
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Look at the sunniest and most exposed elevations first
- Encourage occupiers to report problems at frames
- Make mastic part of routine maintenance checks
- Keep bins and bikes away from communal door frames
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
When to bring in a specialist
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
