How we handle floor joint sealing in Telegraph Hill

Not every floor joint we treat is in a warehouse. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, and an open, grimy joint line looks poor as well as catching wheels. A neat, flush fill makes the floor easier to clean and look after. We work on retail and showroom floors, saw-cut induced joints and forklift and pallet-truck routes, and the failures we’re asked to look at most are chipped and spalling edges along forklift routes and unfilled floor joints collecting dirt and grit. Most enquiries from Telegraph Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up, so it pays to act early.

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.

Why deal with it now?

Open joints are where dirt collects, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Flush, filled joints leave nothing for cleaners to dig out. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Your questions answered

Is hospital work, at somewhere like University Hospital Lewisham, something you do?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is New Cross Gate Retail Park, near Telegraph Hill, within your area?

Yes. Estates, retail parks and business parks around Telegraph Hill, New Cross Gate Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

What information helps you price floor joint sealing?

Send details through our quote form or by email, with the traffic on each area. We then send a fixed quote that shows the products and zones.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Do you use semi-rigid filler or flexible sealant on floor joints?

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is typically right and perimeter or movement joints need flexibility. You will see the choice for each area in the quote.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Quoting for work in Telegraph Hill

We price every job individually. The main factors are:

  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages
  • The total length or number of joints
  • Access and working height

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 we’ll put a fixed figure on it.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Drawings or a marked-up plan, if available
  • Access details, including height
  • Specification clauses that apply
  • What the building is and how it’s used

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send details through our quote form.

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a job in Telegraph Hill, access comes first. Give us the hours we can be on site and we will schedule to suit.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. You receive a fixed quote showing products and phasing.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. We hand each phase back when it can take traffic.

Before we start on site

  • Make sure the joints can be reached
  • Share your working hours and any access restrictions
  • Have the specification and drawings to hand

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Surface by surface

Forklift and pallet-truck routes

Main aisles and cross routes carry the most wheel movements, so their joints wear fastest. Semi-rigid fillers are widely used on these routes to hold the edges up.

Loading bays and dock areas

At loading bays, product choice has to suit the loads, the temperature and the wet. Phasing is planned around your delivery schedule.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Photograph any joint that starts to chip
  • Expect fillers on young slabs to need a top-up
  • Mention any aggressive cleaning regime at quote stage
  • Check joint lines on busy aisles regularly

Young concrete carries on shrinking, so some fillers part slightly from one face. That is common and is normally dealt with by topping up once the slab has settled down in most cases.

Treating joints while the arrises are sound keeps the work simple. After the edges go, repairs come into it, with more downtime and more disruption.

Traffic, movement and joints around Telegraph Hill

At least three named trading, business or retail sites lie within about 3 miles of Telegraph Hill. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. London car parks, loading bays and podium decks often can’t close for long, so the work is broken into short sections agreed with the building manager.

For an estate such as University Hospital Lewisham, 1.4 miles to the south-east of Telegraph Hill, the joints in ramps, decks and long building elevations all need attention over time. For estates staff at a university like University of Greenwich - Greenwich Campus (1.9 miles north-east of Telegraph Hill), building and paving joints are part of the planned maintenance list. Across sites such as Astbury Business Park, 0.8 miles north-west of Telegraph Hill, floor and movement joints can be sealed in phases so units keep working.

Telegraph Hill is about 1 mile south-west of New Cross, in Greater London. Anywhere in SE4, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 764 places in Greater London, from busy centres to rural villages.

Anyone looking for floor joint sealing in SE4, SE15 and SE14 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your site is on Mona Road, Pepys Road and Kitto Road or close by, send details and we’ll quote for floor joints. Nearby places we also cover include Nunhead (1 mile south-west), New Cross (1 mile north-east), Peckham (1 mile north-west), St Johns (1 mile east) and Brockley (1 mile south-east) for floor joints.
