What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Waterproofing layers buried beneath the sealant
- Damaged metal nosings or cover plates over a joint
- Crumbling edges that would give a new bead nothing sound to grip

What happens if it’s left?
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. One visit to deal with every failing joint makes more sense than several trips to a place like Chaldon. Photos of every joint help us quote for the whole job.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Different surfaces, different methods
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
Building owners, agents and FMs in Chaldon
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Chaldon can sit alongside others in a wider programme.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Signs you need expansion joint sealing in Chaldon
Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.
These are often picked up first by site or facilities staff:
- Expansion joints filled with dirt and stones
- Sealant pulling off the joint face
- Damp inside where a wall movement joint has failed
- Spalled or broken joint edges in floors and decks
Hospitals like North Downs Hospital, 1.2 miles to the east of Chaldon, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Questions about Chaldon
Can you take on a job at a hospital such as North Downs Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you cover business parks and estates near Chaldon, such as Church Walk Shopping Centre?
Yes. Our area takes in Chaldon and its surroundings, with estates and business parks such as Church Walk Shopping Centre included. Photos and a short description are enough for a first look.
What timescale should we allow for resealing expansion joints?
Expect a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases and phased work can stretch that to suit your site. We’ll confirm when each area can be used again.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Which product is best for expansion joints?
It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Chaldon 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.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Tell us what induction or permit system the site runs
