How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Rural sites near High Halstow may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- Photos, joint lengths and drawings come to us, or we visit.
- 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.
Getting the site ready
- Agree which areas must stay open
- For older buildings, check the asbestos register before work

About our expansion joint sealing in High Halstow
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you’re dealing with rain penetration at brick or block movement joints and arrises breaking up along floor joints, we can put it right, whatever the surface. For commercial sealant work in High Halstow, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places such as High Halstow, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
A 12-month guarantee applies to all our work in Medway. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we will arrange a return visit.

Why it’s worth doing now in High Halstow
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. We cut out the old seal and prepare the faces every time. Halls, stores and units around places like High Halstow may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

How the job changes by surface
Cladding panel joints
We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
Common questions from High Halstow clients
Is High Halstow too small for you to travel to?
Not at all. High Halstow 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.
Can being near the sea in High Halstow affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can staff carry on working while you are here?
Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Does the weather affect joint sealing?
A wet joint can’t be sealed properly, so external work waits for suitable conditions. The work is simply moved to the next suitable day.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
When to call us in High Halstow
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.
These are often picked up first by site or facilities staff:
- Rain penetration at brick or block movement joints
- Movement joints with split or torn sealant
- Spalled or broken joint edges in floors and decks
- Brittle, chalky sealant on external joints
Schools like High Halstow Primary Academy often have long brick elevations with movement joints that age quietly.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- Their plan for phasing and protecting the area
- Proof of insurance
- Health and safety accreditation such as CHAS
Aftercare for building managers
To get the most from the new sealant:
- Leave barriers in place until fresh joint sealant has cured
- Put movement joints on the planned maintenance inspection round
- Brief car park operatives to protect joint lines during winter clearance
- Act on the first tear or lifting edge rather than waiting
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and 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. Keeping the seal sound avoids all of that.
