Expansion joint sealing for Sonning sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why deal with it now?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we’ll plan around it. One visit to deal with every failing joint makes more sense than several trips to a place like Sonning. Photos of every joint help us quote for the whole job.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Why appoint us
- CSCS-carded applicators
- Failed material removed, not covered up

Expansion joint sealing in Sonning
Brickwork and blockwork walls have vertical movement joints at intervals 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, primed where the manufacturer specifies. Site teams most often ask us about arrises breaking up along floor joints and damp inside where a wall movement joint has failed, on blockwork control joints, precast concrete panel joints and brickwork movement joints. One point of contact handles commercial sealant work in Sonning from the first photographs to the final walk-round, whether it’s one building or several.
For a site near Sonning, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Act on the first tear or lifting edge rather than waiting
- Keep traffic off new joints until the cure time is up
- Keep stones and debris out of open joint lines
- Keep racking legs and heavy point loads off floor joints
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.
FAQs: Sonning
Is a hospital such as Royal Berkshire Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as Loddon Vale Shopping Centre, by Sonning?
Yes. Estates, retail parks and business parks around Sonning, Loddon Vale Shopping Centre among them, are all within reach. A few photos and the unit address let us price the work.
What will the job cost?
There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Why do our movement joints keep failing?
The way it has failed typically 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.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
How the job changes by surface
Cladding panel joints
We confirm what access is in place before pricing. Close-up photographs help us judge the joints, or we visit if they don’t show enough.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed, and we will tell you if any edges need repairing first.
Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Rural sites near Sonning may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- 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.
Getting the site ready
- Point out any areas we must not close
- Share the asbestos register for older buildings
- Let building users know which areas are affected

When to bring in a specialist
For most general trades, sealant is a sideline. 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 anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
