FAQs: East Horndon
Will you take on a block within reach of West Horndon station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you take on work at estates like Brentwood Commercial Park, close to East Horndon?
Yes, sites like Brentwood Commercial Park are within our area, along with the rest of East Horndon. Send details of the unit and the work through our quote form for a quick quote.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.
How do you choose the sealant?
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, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
What the job involves on each surface
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
What we are called out for in East Horndon
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
Most enquiries start with something like this:
- Occupiers reporting cold air round windows
- Complaints coming in block by block
- Estate-wide sealant that is simply worn out
- Window mastic that has split and shrunk
Blocks of flats and mixed-use buildings often cluster around stations such as West Horndon station, 1 mile to the south-west of East Horndon, and their window and balcony mastic tends to age at the same rate across a building.
Questions to ask before you book
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Which product they’ll use, and why it suits the joint
- Can the work be phased to keep areas open?
- Will failed sealant be removed rather than covered?

Cost factors for mastic joints
Your fixed quote is built from the real scope. It takes account of:
- The site’s rules and procedures
- The size and state of each joint
- Working within restricted access windows
- Removal of failed or old sealant
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Sending details for a quote
However big the job, the same details help:
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- A wide shot and a close-up of the area
- Where the site is, with the postcode
To get a fixed quote, phone 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Share the asbestos register when you send details
- Track which buildings were done and when
- Include mastic in your cyclical inspections
- Prioritise elevations facing the weather
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
