Expansion joint sealing in Dummer, done properly
Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. We work on car park decks and ramps, cladding panel joints and blockwork control joints, and the usual reasons a site gets in touch are arrises breaking up along floor joints and previous reseals laid over old sealant. For commercial sealant work in Dummer, you deal with one contact from quote to sign-off, whether it’s one building or several.
In and around smaller places like Dummer, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Different surfaces, different methods
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen, and we’ll confirm the colours available for the specified product.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Around Dummer, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why clients in Dummer choose us
- Colours chosen to suit frames, cladding or finishes where possible

Common problems we fix in Dummer
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.
Common reasons buildings call us in:
- Hardened, cracked sealant on exposed facades
- Water dripping through deck or ramp joints
- Damp inside where a wall movement joint has failed
- Expansion joints filled with dirt and stones
Hospitals like Park Prewett Hospital (to the north of Dummer) have multi-storey or surface car parks whose joints carry vehicles round the clock.
What to look for in a quote

- Who will actually carry out the work
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For a building around Dummer, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
Before we start on site

Advice
Floors, slabs and movement joints in Dummer
Dummer is about 50 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.
Around Dummer, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Questions about Dummer
Is a smaller place like Dummer outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Will our site in Dummer have to close for joint sealing?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Does the weather affect joint sealing?
Weather matters for any external joint because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
