Mastic sealing in Barkingside
For blocks and buildings in Barkingside and across Greater London, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks, and the failures we are asked to look at most are cracked, hardened mastic round windows on a block and mastic failing across several blocks on an estate. A specialist sealant contractor works differently from a general builder: on jobs in Barkingside, preparation and product choice get the time they need.
In a London area such as Barkingside, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Misted or failed double-glazed units
- Leaks from above rather than through a joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
What we seal
- External wall and movement joints
- Communal kitchens and washrooms

What affects the price in Barkingside
A fixed quote reflects the actual work. It allows for:
- The size and state of each joint
- Site requirements such as inductions and permits
- The product specified
- Phasing around occupants
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Specification clauses that apply
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
For a fixed quote, call 01277 525 020 or email the details over, telling us the site location and the nature of the job. You can also send details through our quote form.
Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. All of Greater London is in the ULEZ, and kerbside space in Barkingside can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Preparing the site
- For older buildings, check the asbestos register before work
- Point out any areas we must not close
- Share your working hours and any access restrictions
Getting a fixed quote
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email us.
Advice
What we are called out for in Barkingside
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
What tends to prompt an enquiry:
- Leaks at window and door perimeters
- No planned programme for sealant
- Damaged joints in communal entrances and corridors
- Draughts at frames across a block
If your remit includes a building such as Avanti Court Primary School, frame and door mastic can be programmed for the holidays.
Questions to ask before you book
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?
- Is the sealant right for the movement and the substrate?
- Their plan for phasing and protecting the area
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Common questions from Barkingside clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for
We manage a building near Seven Kings station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
How long does a job like this take?
It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
When is resealing likely to be due?
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 to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
