Expansion joint sealing in Cobham, done properly
The seal is what lets a movement joint do its job. 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. We work on car park decks and ramps, cladding panel joints and blockwork control joints, and what we’re called in for most is torn sealant in brick or block movement joints and leaks through car park deck joints onto the level below. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Cobham is the same: the right product in a properly prepared joint.
In and around smaller places like Cobham, 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.

Keeping the joints sound
A few simple habits keep the new joints working:
- Reopen bays and walkways only after the stated cure time
- Clear dirt from joint lines during routine cleaning
- Inspect exposed joints once the cold weather has passed
- Report split or peeling joint sealant early
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.
Site staff or a sealant specialist?
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.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
How the job changes by surface
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.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.
Questions we are asked in Cobham
Will you take on work at estates like Bowes Industrial Centre, close to Cobham?
Yes. Our area takes in Cobham and its surroundings, with estates and business parks such as Bowes Industrial Centre included. Send details of the unit and the work through our quote form for a quick quote.
Is Cobham off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Who decides which product is used?
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 you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Do you offer coloured sealant?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What if the joint edges are damaged?
Spalled edges need repairing before a new seal will last. Sealing over them leads to early failure.
Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. Around Cobham, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
