Expansion joint sealing for Merrow sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Do you need expansion joint sealing in Merrow?
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises. A sealant that isn’t trafficable won’t last there.
These are often picked up first by site or facilities staff:
- Chipped joint edges on forklift routes
- Joints packed with grit and debris
- Water getting into the wall through a failed joint
- Hardened, cracked sealant on exposed facades
Schools like Bushy Hill Junior School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint
- How long is the guarantee, and what does it include?

Common questions from Merrow clients
Do you take on work at healthcare sites like Mount Alvernia Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Merrow Business Park, close to Merrow?
Yes, sites like Merrow Business Park are within our area, along with the rest of Merrow. Photos and a short description are enough for a first look.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing so the same failure isn’t repeated.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you seal car park deck joints?
Yes. We use a sealant designed for wheel loads and the expected movement.
Different surfaces, different methods
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Record the sealant used and the date in the O&M file
- Brief car park operatives to protect joint lines during winter clearance
- Reopen bays and walkways only after the stated cure time
- Avoid parking heavy plant or pallets on joint lines
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. If anything looks wrong, ring 01277 525 020 or email us with photographs.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
When to bring in a specialist
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 typically costs more in the end than doing them right.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. For a site in Merrow, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Confirm the product named in the specification
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
