How we handle expansion joint sealing in Hanworth
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. If you have debris jammed in movement joints and hardened, cracked sealant on exposed facades, we can put it right, whatever the surface. A single leaking joint is often how a building in Hanworth first comes to us: we look at the rest while we are there and tell you what we find.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Hanworth, as everywhere in London, access, loading and the ULEZ all come into the plan.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions we are asked in Hanworth
Does your area include sites such as Hanworth Trading Estate, near Hanworth?
Yes. Estates, retail parks and business parks around Hanworth, Hanworth Trading Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Is a hospital such as Teddington Memorial 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.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you use silicone or polyurethane in movement joints?
Movement capability matters most. Where two different materials meet, a hybrid sealant can be the better choice.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
How long will the joint resealing take?
It normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. We’ll confirm when each area can be used again.
How a job runs
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Arrange parking or a loading space
- Agree which areas must stay open
- Have the specification and drawings to hand

After the work
To get the most from the new sealant:
- Brief car park operatives to protect joint lines during winter clearance
- Report split or peeling joint sealant early
- Inspect exposed joints once the cold weather has passed
- Clear dirt from joint lines during routine cleaning
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
Why act early in Hanworth
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- Our applicators hold CSCS cards
- 12 months’ guarantee on every job
- CHAS accredited
- Old sealant cut out, never sealed over

How the job changes by surface
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond, so the new seal holds.
For managing agents and facilities managers
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
