Your questions answered
Is Business Centre, near Becontree, within your area?
Yes, sites like Business Centre are within our area, along with the rest of Becontree. Photos and a short description are enough for a first look.
Can you quote for a block close to Chadwell Heath station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do you work in Becontree?
Yes. We cover Becontree. To discuss a job, call the office on 01277 525 020 or send details through our quote form.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Maintenance after handover
To get the most from the new sealant:
- Group repairs into a planned programme
- Track which buildings were done and when
- Have the asbestos survey to hand for older buildings
- Keep bins and bikes away from communal door frames
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
For owners and agents in Becontree
Becontree has two care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We plan around the notices and access you arrange.
If you look after a block within reach of Chadwell Heath station (1.5 miles north-west of Becontree), frame and balcony mastic can be renewed on one programme. For owners of several units at places like Business Centre, 0.9 miles to the north-east of Becontree, one programme can deal with frame and external mastic across the lot.

What we’re called out for in Becontree
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We’ll tell you if the joint edges need repairing before resealing.
Things that normally lead to an enquiry:
- Leaks at window and door perimeters
- Worn sealant at communal door frames
- Complaints coming in block by block
- Open joints in brickwork or panels
Owners of student blocks near University of East London (to the south-west of Becontree) can schedule frame and external mastic for the summer vacation.
What to look for in a quote
- How joint depth will be controlled
- Is the sealant right for the movement and the substrate?
- How the existing material will be dealt with
- Are they CHAS accredited or on Constructionline?
How the job changes by surface
External movement joints
Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.
Tenement and older buildings
Stone needs a neutral-cure product and we choose accordingly.
When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Leaks through the frame itself rather than the perimeter
- Misted or failed double-glazed units
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.
