Expansion joint sealing in Gardeners Green, done properly
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you’re dealing with new sealant over old, now failing and hardened, cracked sealant on exposed facades, we can help, on car park decks and ramps, precast concrete panel joints and blockwork control joints alike. For commercial sealant work in Gardeners Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
Jobs around smaller places like Gardeners Green are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. Around Gardeners Green, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Why us?
- Over 20 years of commercial sealing
- Joints cleaned back to sound surfaces
- A range of standard colours, depending on the product
- Colours confirmed for the specified product

What else we do in Gardeners Green
When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. If others near Gardeners Green need work, visits can be combined. A fixed quote is given before anything starts.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry.
- 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.
- We check every joint before sign-off, and the work carries our 12-month guarantee.

After the work
After handover, these steps help:
- Inspect movement joints alongside other routine building checks
- Note which joints were done, when, and with what
- Keep stones and debris out of open joint lines
- Reopen bays and walkways only after the stated cure time
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
Questions we are asked in Gardeners Green
Is Gardeners Green too small for you to travel to?
Not at all. Gardeners Green is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Is a hospital such as Wokingham Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing and both need a flexible seal.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you guarantee expansion joint work?
The workmanship is guaranteed for 12 months from sign-off. Regular sweeping and inspection help the joints last.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
What the job involves on each surface
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement priming where the maker calls for it.
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability.
