About our floor joint sealing in Pinner Green

Sometimes the concrete either side of a joint has already spalled. Filling against a crumbled arris won’t hold for long, so we’ll tell you if the joint edges need repairing first and leave that decision with you. The enquiries we see most involve sealant pulled out along a truck route and old filler gone hard, cracked or loose, on loading bays, forklift and pallet-truck routes and saw-cut induced joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Pinner Green is the same: the right product in a properly prepared joint.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Pinner Green, as everywhere in London, access, loading and the ULEZ all come into the plan.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions about Pinner Green

Is hospital work, at somewhere like Northwood and Pinner Cottage Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Do you work in London buildings with loading restrictions?

Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.

Which is better for warehouse joints, filler or sealant?

It depends on the traffic and the movement. Trafficked joints on truck routes normally need a semi-rigid filler to support the edges, while joints that move more take a flexible sealant.

How soon can traffic go back on the floor?

Cure times vary with the product and the conditions. We will give you a time for each zone when we agree the phasing.

Why has the filler pulled away from one side?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

What information helps you price floor joint sealing?

A rough joint length, a few photos and a site plan let us give a quick quote. We can visit where that helps, and you can give us a call on 01277 525 020 or use the quote form to arrange it.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How much there is to seal
  • Any access equipment needed
  • Which sealant the job calls for
  • Joint width, depth and condition

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • The product your specification calls for
  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.

Floor joint sealing in Pinner Green: the local picture

Less than 3 miles from Pinner Green there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager.

For an occupier at a site such as Waverley Industrial Park, which lies east of Pinner Green, the joints at loading doors and dock levellers usually see the hardest wear. Phasing is what makes joint work possible on busy sites such as Harrovian Business Village (2.6 miles south-east of Pinner Green): one bay, aisle or car park row at a time. Retail centres such as St. George's Shopping Centre (2.6 miles south-east of Pinner Green) have floors, service yards and car parks with joints under constant traffic.

Pinner Green is about 2 miles north-east of Ruislip, in Greater London. We cover commercial sites throughout Pinner Green, whether it’s a single job or part of a planned programme.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Wide or random cracking that suggests a structural issue
  • Spalled arrises, which need an edge repair first
  • Unstable slabs moving under traffic

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly.

Where we work in Pinner Green

Why it’s worth doing now in Pinner Green

Dirt and spillage gather in open joints, out of reach of the floor cleaner. In shops, showrooms and clean production areas that matters for hygiene and appearance. Flush, filled joints leave nothing for cleaners to dig out. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Different surfaces, different methods

Construction joints

Day joints vary, with or without armoured edges. We’ll tell you if the edges or any armouring look like they need attention before filling.

Retail and showroom floors

We plan shop-floor work so trading can continue. Give us your opening pattern and access windows and the phasing follows.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Planning a London job such as one in Pinner Green starts with access. Give us the hours we can be on site and we will schedule to suit.

  1. A floor survey records every joint, its edges and what crosses it.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Send any specification or drawings in advance
  • Agree which areas must stay open
  • Share the asbestos register for older buildings

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
