Floor joint sealing for businesses in Northwick Park
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Expect fillers on young slabs to need a top-up
- Sweep debris out of open joints until they can be filled
- Start with the dock areas, where joints fail soonest
- Check joint lines on busy aisles regularly
If a joint we filled starts to break up within 12 months, tell us and we’ll arrange a look. Beyond that, an inspection once or twice a year catches failing joints early.
Every vehicle on a busy aisle hits a damaged joint. Sorting it early looks after your equipment as well as the slab.
Floor joint sealing in Northwick Park
Not every floor joint we treat is in a warehouse. Shops, showrooms and trade counters have joints that take trolleys, foot traffic and scrubber-driers, where a gappy, dirty joint looks untidy and snags castors. A neat, flush fill makes the floor easier to clean and look after. We work on forklift and pallet-truck routes, joints along racking aisles and saw-cut induced joints, and the failures we’re asked to look at most are old filler gone hard, cracked or loose and saw-cut joints left open and packed with grit. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Northwick Park is the same: the right product in a properly prepared joint.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

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 before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Northwick Park can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We walk the floor and mark up joint widths, edge damage and traffic routes.
- You receive a fixed quote showing products and phasing.
- Old fill and packed debris come out until both faces are sound.
- Dust is vacuumed out and primer applied where specified.
- The joint is filled to its specified depth and trimmed level.
- We hand each phase back when it can take traffic.
Getting the site ready
- Flag any permit to work we will need
- Share the asbestos register for older buildings
- Move anything stored against the joints

What the job involves on each surface
Retail and showroom floors
Shop and showroom floors often have exposed slab joints, especially with polished or coated concrete. A flush, neat fill in a suitable colour keeps the floor looking right, and we will confirm the colours available for the specified product.
Isolation joints at walls and columns
Joints at walls and columns are often missed when floors are sealed and fill up with dirt. We include them in the survey.
What happens if it’s left?
Holding off until the whole floor can close can take a long time. Phased in zones, the busiest routes can be treated first while the rest of the floor carries on. Getting scaffold, permits or access booked in Northwick Park takes effort, so it makes sense to deal with every failing joint while access is in place.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Northwick Park: questions and answers
Would you work within a site like Northwick Park Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as Harrovian Business Village, by Northwick Park?
Yes. Our area takes in Northwick Park and its surroundings, with estates and business parks such as Harrovian Business Village included. Send details of the unit and the work through our quote form for a quick quote.
Do you guarantee industrial floor joints?
A 12-month guarantee covers the work we do. It applies to our workmanship rather than structural movement or accidental damage.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.

When it isn’t the sealant
