FAQs: Stanstead Abbotts
Is a smaller place like Stanstead Abbotts outside your area?
Not at all. Stanstead Abbotts is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Would you work within a site like Princess Alexandra Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Why do our movement joints keep failing?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first since each needs a different fix.
Do you reseal car park expansion joints?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.
Do you use silicone or polyurethane in movement joints?
Whatever suits the joint and the specification. We name the proposed product in the quote so there are no surprises.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Leave it or put it right?
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind, and a second visit means paying for access again. Where it helps, we quote both options. Converted and older buildings near places like Stanstead Abbotts tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Advice
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Keep scrapers and ploughs from dragging across joint sealant
- Put movement joints on the planned maintenance inspection round
- Keep racking legs and heavy point loads off floor joints
- Keep traffic off new joints until the cure time is up
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, call the office on 01277 525 020 or email drawings and photos with photos.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Resealing early limits the damage.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Concrete or masonry repairs along the arrises
- Cracking or settlement that calls for an engineer’s assessment
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.
What we seal
- Car park decks and ramps
- Blockwork control joints
- Brickwork movement joints
- Cladding panel joints

Joints that move: notes for Stanstead Abbotts

Different surfaces, different methods
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.
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 with bays done in phases so the car park keeps running.
