Need expansion joint sealing in Aldham?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What the job involves on each surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it, then seal and tool the joint.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Concrete or masonry repairs along the arrises
  • Changing the joint layout or spacing of a structure
  • Movement on a scale no sealant is meant to absorb

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

  • Car park decks and ramps
  • Cladding panel joints
  • Precast concrete panel joints
  • Brickwork movement joints
  • Blockwork control joints
  • Podiums and floor movement joints

Floors, slabs and movement joints in Aldham

The 3 miles around Aldham 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. Aldham is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

Large sites such as Essex County Hospital (to the east of Aldham) have car parks, service roads and long elevations with movement joints in brick and panels. Retail parks like Stane Retail Park (1.8 miles east of Aldham) have long runs of car park and yard joints taking daily traffic.

Aldham is about 5 miles west of Colchester, in Essex. We cover Aldham and the rest of Essex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 644 places across Essex fall within our area, Aldham among them. We also cover London, around 47 miles from Aldham.

Commercial sites across CO6 are covered. Streets here include Green Lane, Hardings Close and Church Grove. Just outside Aldham, we also work in Copford (1 mile south-east), Marks Tey (2 miles south-west), Little Tey (2 miles south-west), Mulberry Green (2 miles south) and Easthorpe (3 miles south). A short drive away, we cover Colchester (5 miles east), Braintree (10 miles west), Maldon (13 miles south), Witham (9 miles south-west), Camulodunum (4 miles east) and Halstead (7 miles north-west).

Local landmarks in Aldham

We work on buildings around The Queen's Head Public House. For rail, the closest station is Marks Tey station, about 1.2 miles south. A little further out are Birch Castle (4.1 miles south) and Essex County Hospital (4.4 miles east). Green spaces nearby include Iron Latch.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. If others near Aldham need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Agree which areas must stay open

Common problems we fix in Aldham

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.

Common reasons buildings call us in:

  • Sealant peeling off one face of the joint
  • Joints packed with grit and debris
  • New sealant over old, now failing
  • Water dripping through deck or ramp joints

In a school such as Holy Trinity CofE Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

What your quote should include

  • Their plan for phasing and protecting the area
  • Do they follow the manufacturer’s priming guidance?
  • Will CSCS-carded applicators be on site?
  • Is the sealant right for the movement and the substrate?

Our contractor checklist

Aftercare for building managers

After handover, these steps help:

  • Reopen bays and walkways only after the stated cure time
  • Clear dirt from joint lines during routine cleaning
  • Keep scrapers and ploughs from dragging across joint sealant
  • Treat a small split as a warning, not a cosmetic issue

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

Aldham: questions and answers

Do you take on work at healthcare sites like Essex County Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is a smaller place like Aldham outside your area?

Not at all. Aldham is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

What timescale should we allow for resealing expansion joints?

Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. We confirm the timescale with the quote, including any phasing.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

What happens if it rains on the day?

A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.

What do you charge?

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

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
