Common problems we fix in Shadwell
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
Common reasons buildings call us in:
- Draught complaints from residents or tenants
- A mix of products and colours from past repairs
- Failed external movement joints
- Window mastic that has split and shrunk
Blocks of flats and mixed-use buildings often cluster around stations such as Wapping station (to the south-west of Shadwell) and their window and balcony mastic tends to age at the same rate across a building.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
- Are they CHAS accredited or on Constructionline?
- How long is the guarantee, and what does it include?
Mastic sealing in Shadwell
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, external wall and movement joints and communal kitchens and washrooms, and the failures we are asked to look at most are communal area joints that look neglected and failed external movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Shadwell, preparation and product choice get the time they need.
Across Greater London, Shadwell included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Surface by surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
Your questions answered
Does your area include sites such as Princes Court Business Centre, near Shadwell?
Yes. We cover Shadwell and the area around it, including industrial estates, business parks and retail parks such as Princes Court Business Centre. A few photos and the unit address let us price the work.
Will you work in a care home in Shadwell without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Group repairs into a planned programme
- Keep bins and bikes away from communal door frames
- Track which buildings were done and when
- Prioritise elevations facing the weather
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.

Advice

Also in Shadwell
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Leaks through the frame itself rather than the perimeter
- Asbestos-containing sealant, which we don’t remove
- Broken glass or failed sealed units
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 before you book.
