Need expansion joint sealing in Little Dunmow?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Cost factors for movement joints

These are the things that shape the price:

  • How much there is to seal
  • How much existing material needs removing
  • Any access equipment needed
  • Induction, permit and paperwork requirements

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area
  • The site address and postcode
  • The type of building and who uses it

To get a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.

Expansion joint sealing in Little Dunmow, done properly

We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, podiums and floor movement joints and car park decks and ramps, and what we are called in for most is joints packed with grit and debris and previous reseals laid over old sealant. A single leaking joint is often how a building in Little Dunmow first comes to us: we look at the rest while we are there and tell you what we find.

Work in a smaller place like Little Dunmow is typically one building at a time, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

How the job changes by surface

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.

Traffic, movement and joints around Little Dunmow

Little Dunmow is about 33 miles from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Little 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.

In a school such as The Flitch Green Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak. On industrial estates such as Martels Industrial Estate, 1.7 miles to the south-west of Little Dunmow, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Phasing is what makes joint work possible on busy sites such as Oak Industrial Estate (1.8 miles west of Little Dunmow): one bay, aisle or car park row at a time.

Little Dunmow is about 6 miles west of Braintree, in Essex. Commercial clients in Little Dunmow use us for work on movement joints. Little Dunmow is one of 644 places we cover in Essex. Sites around London have their own page, roughly 33 miles from Little Dunmow.

Commercial sites across CM6 are covered. Among the streets we cover are Station Road, Worrin Road and Durand Lane, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Brookstreet (1 mile west), Felsted (1 mile east), Causeway End (1 mile south-east), North End (1 mile south) and Watch House Green (2 miles east) for movement joints. Bigger towns within reach include Chelmsford (9 miles south), Braintree (6 miles east), Harlow (14 miles south-west), Maldon (15 miles south-east), Witham (10 miles south-east) and Saffron Walden (13 miles north-west).

Maintenance after handover

After handover, these steps help:

  • Include every elevation and deck joint in periodic inspections
  • Report split or peeling joint sealant early
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep product details with the building records for the next reseal

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Your questions answered

Is a hospital such as Braintree Community Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Does your area include sites such as Martels Industrial Estate, near Little Dunmow?

Yes. We cover Little Dunmow and the area around it, including industrial estates, business parks and retail parks such as Martels Industrial Estate. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

How long will the joint resealing take?

The metres of joint, the access and the amount of removal decide it. Typically it takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. What matters most for a job in Little Dunmow is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Send any specification or drawings in advance
  • Move anything stored against the joints
  • Let us know about inductions and permits

Ask for a quote

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or use the quote form.

  • Proprietary pre-formed expansion joint systems
