How we handle expansion joint sealing in Brasted Chart
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we will say so before sealing, and phased work keeps areas in use. The enquiries we see most involve movement joints with split or torn sealant and joints packed with grit and debris, on brickwork movement joints, precast concrete panel joints and blockwork control joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Brasted Chart it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Brasted Chart, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Brasted Chart
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.
These are often picked up first by site or facilities staff:
- Spalled or broken joint edges in floors and decks
- Weathered movement joint sealant that no longer flexes
- New sealant over old, now failing
- Torn sealant in brick or block movement joints
Office parks like Salters Heath Business Centre (2.7 miles east of Brasted Chart) have decks, ramps and clad elevations whose joints take movement every day.
Questions to ask before you book
- Their approach to joint depth and backing
- Whether old or failed sealant will be cut out, not overlaid
- Are they CHAS accredited or on Constructionline?
- Do they follow the manufacturer’s priming guidance?
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Brasted Chart may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.

Questions about Brasted Chart
Does your area include sites such as Salters Heath Business Centre, near Brasted Chart?
Yes, sites like Salters Heath Business Centre are within our area, along with the rest of Brasted Chart. A few photos and the unit address let us price the work.
Is Brasted Chart off your patch?
Not at all. Brasted Chart is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you use silicone or polyurethane in movement joints?
Whatever suits the joint and the specification. We name the proposed product in the quote.
What exactly is a movement joint?
The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
Looking after the joints
After handover, a little attention goes a long way:
- Keep traffic off new joints until the cure time is up
- Clear dirt from joint lines during routine cleaning
- Keep racking legs and heavy point loads off floor joints
- Inspect movement joints alongside other routine building checks
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall. A sound seal keeps the joint working.
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Leave it or put it right?
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. We cut out the old seal and prepare the faces every time. One visit to deal with every failing joint makes more sense than several trips to a place like Brasted Chart, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
