Floor joint sealing for St George's Fields sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Floor joint sealing for commercial buildings in St George's Fields

We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Each job is priced from the metres of joint, their condition and the access windows we get, and the quote is fixed before we mobilise. We work on retail and showroom floors, saw-cut induced joints and forklift and pallet-truck routes, and what we are called in for most is cracked and crumbling joint fill and soft sealant dragged out of trafficked joints. Looking for mastic applicators who cover St George's Fields? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Areas such as a loading bay or car park deck in St George's Fields usually have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • A failing floor coating, which is a flooring contractor’s job
  • Structural cracking in the slab

If you are not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Where we work in St George's Fields

  • Saw-cut induced joints
  • Loading bays
  • Forklift and pallet-truck routes
  • Joints along racking aisles
  • Construction joints
  • Retail and showroom floors

From enquiry to sign-off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

What we need from you

  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use

Getting a fixed quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email the details over.

Different surfaces, different methods

Flexible floor sealants

Polyurethane floor sealants are available in a range of colours, and we’ll confirm what the specified product offers.

Saw-cut induced joints

Sawn joints make up most of the joint length in a typical industrial floor. We clear them back to clean concrete and fill them to the depth the product calls for, finishing flush with the slab.

Slabs, ramps and loading bays in St George's Fields

St George's Fields has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. In London, decks, bays and service yards typically have to keep running, so the work is broken into short sections agreed with the building manager.

Sites like Evelina London Children's Hospital, 0.6 miles to the west of St George's Fields, carry ambulances, deliveries and visitors’ cars over their road and deck joints. For an occupier at a site such as Grand Vitesse Industrial Estate, less than half a mile north of St George's Fields, the joints at loading doors and dock levellers normally see the hardest wear. Retail centres such as Southernwood Retail Park, 1.5 miles to the south-east of St George's Fields, have floors, service yards and car parks with joints under constant traffic.

St George's Fields is about 1 mile west of London, in Greater London. We send applicators to St George's Fields for floor joints, handled exactly as we handle every other area. St George's Fields is one of 764 places we cover in Greater London for floor joints.

Business premises anywhere in SE1, SE11 and SE17 are within our area. Streets here include York Road, Spur Road and Bear Lane. Access to St George's Fields is via the A300 and A302. Just outside St George's Fields, we also work in Elephant and Castle (1 mile south-east), Newington Butts (1 mile south-east), Vauxhall (1 mile south-west), Lambeth (1 mile south-west) and Westminster (1 mile west).

Why it’s worth doing now in St George's Fields

Painting or coating straight over joints rarely lasts. Joints need their own treatment before or alongside any coating work. Getting scaffold, permits or access booked in St George's Fields takes effort, so it makes sense to deal with every failing joint while access is in place.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

FAQs: St George's Fields

Would you work within a site like Evelina London Children's Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Will you take on work at estates like Grand Vitesse Industrial Estate, close to St George's Fields?

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

How soon can traffic go back on the floor?

Each product has its own cure time and cooler floors take longer. Phasing is planned with that in mind.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes a day or more, depending on the metres of joint and how many zones the floor is split into. For bigger or phased jobs, we’ll set out a timescale with the quote.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Mention any aggressive cleaning regime at quote stage
  • Start with the dock areas, where joints fail soonest
  • Hold traffic back until the product has cured
  • Stop forks and pallets being dragged across joints

Problems inside the 12-month guarantee period are ours to put right. Beyond that, an inspection once or twice a year catches failing joints early.

Joints are easiest to look after when someone checks them regularly. We can quote a programme that starts with the busiest areas and keeps on top of the rest.
