Common problems we fix in Hardwick
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens.
Site and facilities staff are often the first to spot these:
- Sealant pulling off the joint face
- Torn sealant in brick or block movement joints
- Chipped joint edges on forklift routes
- Layers of sealant in a movement joint
For a school such as Old School Room Chapel, playground and building joints can be done in the holidays.

Expansion joint sealing in Hardwick, done properly
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. We work on precast concrete panel joints, cladding panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are new sealant over old, now failing and movement joints with split or torn sealant. A specialist sealant contractor works differently from a general builder: in Hardwick, that means joint design, primers and backing rod as standard.
Halls, schools and small commercial buildings near places like Hardwick have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we’ll come back to it.

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, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Avoid parking heavy plant or pallets on joint lines
- Include every elevation and deck joint in periodic inspections
- Report split or peeling joint sealant early
- Check joints after long freezing spells
Fresh joint sealant needs its full cure time before it takes traffic or water. 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.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.
What the job involves on each surface
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces, with primer where specified.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we’ll tell you if any edges need repairing first.
Why deal with it now?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too. Where it helps, we quote both options. Around Hardwick, 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.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Your questions answered
Is Hardwick too small for you to travel to?
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.
Would you work within a site like Tindal Centre?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How long does movement joint sealing take?
It usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Cure time before reopening is confirmed on the day.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you seal car park deck joints?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we’ll tell you if any edges need repairing first.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
