About our mastic sealing in Beckton
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and what we are called in for most is draught complaints from residents or tenants and old repairs sealed over failed mastic. One point of contact handles commercial sealant work in Beckton from the first photos to the final walk-round, for single jobs and planned programmes alike.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How the quote is worked out
Each job is priced on its own details. The main factors are:
- The site’s rules and procedures
- How accessible the joints are
- The product specified
- Removal of failed or old sealant
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Details that help us quote
A few photographs plus some basic facts will normally do. It helps to include:
- The type of building and who uses it
- Your programme or deadline
- How the joints are reached, and at what height
- Where the site is, with the postcode
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email a schedule or drawings.
When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Failed window or door frames, which need a window contractor
- Asbestos-containing sealant, which we don’t remove
If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Joints and surfaces we work on

What the job involves on each surface
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.

Leave it or put it right?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Common questions from Beckton clients
Do you work for managing agents with blocks near Woolwich station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Do you work in occupied care homes around Beckton?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do you seal on top of existing 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.

Advice
After the work
Once the work is signed off, a little attention goes a long way:
- Encourage occupiers to report problems at frames
- Protect low-level joints in entrances
- Track which buildings were done and when
- Share your contractor requirements early
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
