From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and we clear our waste as we work. If neighbouring businesses or buildings around Great Dunmow need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Warn occupants and staff about the work
- Tell us your opening times and when work is allowed

How we handle expansion joint sealing in Great Dunmow
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. Most enquiries involve spalled or broken joint edges in floors and decks and rain penetration at brick or block movement joints, across brickwork movement joints, blockwork control joints and precast concrete panel joints. Facilities teams, main contractors and managing agents in Great Dunmow tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around places the size of Great Dunmow, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or send details through our quote form and we will arrange a return visit.

What else we do in Great Dunmow
Where floor joints take the most wear near Great Dunmow
Great Dunmow is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. The 3 miles around Great Dunmow take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
At places like Ongar Road Industrial Estate, which lies south-east of Great Dunmow, joints are sealed a section at a time so operations carry on. For a school such as Dunmow St Mary's Primary School, playground and building joints can be done in the holidays. For an occupier at a site such as Station Yard Industrial Park, 0.5 miles south-east of Great Dunmow, the joints at loading doors and dock levellers normally see the hardest wear.
Great Dunmow is about 9 miles west of Braintree, in Essex. Commercial clients in Great Dunmow use us for work on movement joints, as part of our coverage of Essex. Great Dunmow is one of 644 places we cover in Essex. We also cover London, some 32 miles away.

When to bring in a specialist
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.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Removal of failed or old sealant
- Backing rod, priming and other preparation
- Location, for remote and island sites
- Access and working height
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
Sending details for a quote
However big the job, the same details help:
- Anything awkward about access or site hours
- When you need the work done
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, call 01277 525 020 or email the details over.
Different surfaces, different methods
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, usually low-modulus, with backing rod setting the depth.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again.
What happens if it’s left?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We’ll flag where edges need repair before sealing. For buildings in places like Great Dunmow, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
A quote for movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Your questions answered
Does your area include sites such as Station Yard Industrial Park, near Great Dunmow?
Yes. We cover Great Dunmow and the area around it, including industrial estates, business parks and retail parks such as Station Yard Industrial Park. Send details of the unit and the work through our quote form for a quick quote.
Does a site in Great Dunmow have to shut while its joints are sealed?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
What exactly is a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped and the way they’re sealed is similar.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
