What we’re called out for in Strand-on-the-Green
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
Most enquiries start with something like this:
- Brittle, chalky sealant on external joints
- Torn sealant in brick or block movement joints
- Layers of sealant in a movement joint
- Expansion joints filled with dirt and stones
Across sites such as Phoenix Trading Estate, which lies north-west of Strand-on-the-Green, floor and movement joints can be sealed in phases so units keep working.

- How long is the guarantee, and what does it include?
- How the existing material will be dealt with
- Proof of insurance
- Whether primer will be used where the manufacturer specifies it
Expansion joint sealing in Strand-on-the-Green, done properly
Brickwork and blockwork walls have vertical movement joints at intervals. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. Site teams most often ask us about spalled or broken joint edges in floors and decks and layers of sealant in a movement joint, across podiums and floor movement joints, brickwork movement joints and precast concrete panel joints. For commercial sealant work in Strand-on-the-Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around Strand-on-the-Green, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email the details over and we will come back to it.

What the job involves on each surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed, and we’ll tell you if any edges need repairing first.
What affects the price in Strand-on-the-Green
The price varies from site to site. It mainly depends on:
- Whether the work must be split into stages
- Location, for remote and island sites
- Access and working height
- Induction, permit and paperwork requirements
A quote for movement joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Access details, including height
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email drawings and photos.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Strand-on-the-Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Flag any permit to work we will need
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000

Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Record the sealant used and the date in the O&M file
- Leave barriers in place until fresh joint sealant has cured
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Put movement joints on the planned maintenance inspection round
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.
FAQs: Strand-on-the-Green
Is hospital work, at somewhere like Clayponds Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you take on work at estates like Kew Retail Park, close to Strand-on-the-Green?
Yes, sites like Kew Retail Park are within our area, along with the rest of Strand-on-the-Green. A few photos and the unit address let us price the work.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
What’s the difference between an expansion joint and a movement joint?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
