FAQs: Stock
Do you work for managing agents with blocks near Billericay 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.
Will you price a mastic programme across our Stock portfolio?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
Does weather matter for sealant work?
It can, when the joints are outside. 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. Internal work is far less affected.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you work in Stock?
Yes. We take on work across Stock.
Mastic sealing in Stock
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you are dealing with old repairs sealed over failed mastic and no planned programme for sealant, we can put it right. A specialist sealant contractor works differently from a general builder: in Stock, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Stock, we group work so one trip covers it. Photos of each elevation help us quote accurately.
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’re clear about what is covered before work starts.

When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Asbestos-containing sealant, which we don’t remove
- Frames that are rotten, warped or broken
Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.
What we seal
- Balcony and threshold joints
- External wall and movement joints

- Window and door perimeters on blocks
- Communal kitchens and washrooms

Advice
Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Converted and older buildings near places like Stock tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why appoint us
- Workmanship guaranteed for 12 months
- Coloured sealants to suit the setting, where available
- Constructionline member for supplier checks
- RAL and finish matching where the product range allows

What sets the cost
The price varies from site to site. It mainly depends on:
- The product specified
- Location, for remote and island sites
- How much existing material needs removing
- The size and state of each joint
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email drawings and photos.
Looking after buildings in and around Stock
At about 26 miles from central London, Stock is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
Buildings close to stations like Billericay station, 2.7 miles south-west of Stock, are often flats over shops, with frame mastic to keep sound. Historic properties like Ingatestone Hall, 2.5 miles to the west of Stock, show the age of some local stock, where frame mastic must suit soft brick or stone. Site managers at schools like Stock Church of England Primary School can fit frame mastic into the summer works.
Stock is about 3 miles north-east of Billericay, in Essex. Our applicators travel to Stock for work on mastic joints, handled exactly as we handle every other area. Stock is one of 644 places we cover in Essex. Our London page has more on work in that area (26 miles or so).

Nearby places we also cover include Margaretting Tye (2 miles north), Ramsden Heath (2 miles south-east), Margaretting (2 miles north-west), Downham (3 miles south-east) and Billericay (3 miles south-west) for mastic joints.

Around Stock
Locally, jobs take us to sites close to The Hoop Public House and Mayflower High School, among other places. For rail, the closest station is Billericay station, about 2.7 miles south-west. Nearby you will also find Mayflower Community Hospital (3.4 miles south-west). Not far away are Norsey Wood.
Owners, agents and contractors
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Stock can form part of a wider programme.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Protect low-level joints in entrances
- Have the asbestos survey to hand for older buildings
- Keep a record of when each building was resealed
- Include mastic in your cyclical inspections
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
