Expansion joint sealing for commercial buildings in Chalfont St Giles
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on blockwork control joints, car park decks and ramps and cladding panel joints, and what we’re called in for most is new sealant over old, now failing and joints where the bead has lost adhesion. For commercial sealant work in Chalfont St Giles, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In a smaller place such as Chalfont St Giles, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What the job involves on each surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.
Site staff or a sealant specialist?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Leave it or put it right?
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a job in Chalfont St Giles, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Send any specification or drawings in advance
- Warn occupants and staff about the work

Advice
Questions about Chalfont St Giles
Is Chalfont St Giles too small for you to travel to?
No. Places such as Chalfont St Giles are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work on a hospital site such as Amersham Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What if the joint edges are damaged?
Sound edges are essential. If they’re damaged, we will say so before any sealing.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Why has the sealant in our expansion joints split?
The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
Can you seal joints in cold or wet weather?
A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Crumbling edges that would give a new bead nothing sound to grip
- Proprietary pre-formed expansion joint systems
- Changing the joint layout or spacing of a structure
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
