Mastic sealing in West Silvertown, done properly
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. Most enquiries involve no planned programme for sealant and movement joints with sealant missing, on shopfronts below residential blocks, external wall and movement joints and window and door perimeters on blocks. A single leaking joint is often how a building in West Silvertown first comes to us: we look at the rest while we’re there and tell you what we find.
For managing agents in West Silvertown, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think.

What sets the cost
Before we quote, we look at:
- Removal of failed or old sealant
- The site’s rules and procedures
- Whether the work must be split into stages
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Clear photos of the problem areas
- The site address and postcode
- The type of building and who uses it
- The product your specification calls for
For a fixed quote, phone 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Log resealing dates block by block
- Plan resealing building by building rather than complaint by complaint
- Share your contractor requirements early
- Check sealant joints during planned building inspections
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area.
