Expansion joint sealing in Heronsgate, done properly
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. Site teams most often ask us about spalled or broken joint edges in floors and decks and sealant pulling off the joint face, across precast concrete panel joints, podiums and floor movement joints and blockwork control joints. A single leaking joint is often how a building in Heronsgate first comes to us: we look at the rest while we are there and tell you what we find.
For a site near Heronsgate, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

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, normally low-modulus, with backing rod setting the depth.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Heronsgate, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- Send your site hours and access windows
- Explain the parking and delivery arrangements

Why it’s worth doing now in Heronsgate
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. One visit to deal with every failing joint makes more sense than several trips to a place like Heronsgate. Send photographs of each area and we will quote for the lot.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Heronsgate: questions and answers
Is a smaller place like Heronsgate outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is Woodcock Hill Industrial Estate, near Heronsgate, within your area?
Yes. Our area takes in Heronsgate and its surroundings, with estates and business parks such as Woodcock Hill Industrial Estate included. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do the joint edges need to be sound before sealing?
Broken arrises have to be put right before resealing. Sealing over them leads to early failure.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Can the sealant be colour-matched?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Quotes vary with the job. It mainly depends on:
- Location, for remote and island sites
- Backing rod, priming and other preparation
- The site’s rules and procedures
- The total length or number of joints
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Before you send an enquiry
However big the job, these details speed things up:
- When you need the work done
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- The site address and postcode
