Advice
Why act early in Dagenham Green
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. In Dagenham Green, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

Blocks in London are typically run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We work to your notice and access plan.
Buildings close to stations like Dagenham Dock station (to the south-west of Dagenham Green) are often flats over shops, with frame mastic to keep sound. For owners of several units at places like Merrielands Retail Park, which lies north-west of Dagenham Green, one programme can deal with frame and external mastic across the lot. Schools and community buildings such as Marsh Green Primary School need frame and external mastic kept sound like any building.

What the job involves on each surface
Commercial and mixed-use buildings
Commercial occupiers usually stay open during the work so the work is phased.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Broken glass or failed sealed units
- Substrate edges that need repairing first
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Surfaces we seal
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Common questions from Dagenham Green clients
Can you quote for a block close to Dagenham Dock station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
