Expansion joint sealing in Strawberry Hill
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on podiums and floor movement joints, car park decks and ramps and precast concrete panel joints, and what we are called in for most is joints where the bead has lost adhesion and car park joints leaking onto vehicles below. Most enquiries from Strawberry Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Questions we are asked in Strawberry Hill
Is Newmans Shipyard & Business Park, near Strawberry Hill, within your area?
Yes. Estates, retail parks and business parks around Strawberry Hill, Newmans Shipyard & Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Can you work on a hospital site such as Teddington Memorial Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Does the weather affect joint sealing?
Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

Signs you need expansion joint sealing in Strawberry Hill
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.
Things that usually lead to an enquiry:
- Weathered movement joint sealant that no longer flexes
- Spalled or broken joint edges in floors and decks
- Water getting into the wall through a failed joint
- Torn sealant in brick or block movement joints
Hospital campuses such as Teddington Memorial Hospital (0.9 miles south of Strawberry Hill) grow in stages, leaving movement joints wherever new blocks meet old.
What your quote should include
- What site paperwork they can supply
- How the joint faces will be prepared and primed
- How the existing material will be dealt with
- Will CSCS-carded applicators be on site?
Surface by surface
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.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in and flag any joint that seems undersized.
Expansion joint sealing around Strawberry Hill: how the place shapes the job
Strawberry Hill has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time.
For estates staff at a university like St Mary's University, less than half a mile to the south of Strawberry Hill, building and paving joints are part of the planned maintenance list. Phasing is what makes joint work possible on busy sites such as Heathlands Industrial Estate (0.5 miles north of Strawberry Hill): one bay, aisle or car park row at a time.

How a job runs
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a job in Strawberry Hill, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- 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.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
- Let building users know which areas are affected

What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Crumbling edges that would give a new bead nothing sound to grip
- Waterproofing layers buried beneath the sealant
- Movement on a scale no sealant is meant to absorb
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.
What we seal
- Blockwork control joints
- Car park decks and ramps
- Brickwork movement joints
- Precast concrete panel joints
- Podiums and floor movement joints
- Cladding panel joints
Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Keep traffic off new joints until the cure time is up
- Avoid parking heavy plant or pallets on joint lines
- Keep scrapers and ploughs from dragging across joint sealant
- Put movement joints on the planned maintenance inspection round
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.
