How we handle floor joint sealing in Old Windsor

We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. That tells us whether semi-rigid filler or flexible sealant suits each run and the answer can differ from one zone to the next. We work on joints along racking aisles, saw-cut induced joints and forklift and pallet-truck routes, and the failures we are asked to look at most are soft sealant dragged out of trafficked joints and brittle joint filler breaking up. One point of contact handles commercial sealant work in Old Windsor from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Around Old Windsor, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. Getting widths, depths and traffic details up front means one visit, not two.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Work in places the size of Old Windsor is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. You get a fixed quote with the product and the phasing set out.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. The area is handed back once it has cured enough to take traffic.

What we need from you

  • Tell staff and tenants when we will be in
  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements

Advice

What affects the price in Old Windsor

Quotes vary with the job. Expect it to depend on:

  • Joint width, depth and condition
  • The product specified
  • Working within restricted access windows
  • Removal of failed or old sealant

A quote for floor joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The postcode of the building
  • The type of building and who uses it
  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or use the quote form to discuss it first.

Site staff or a sealant specialist?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Floor joint sealing in Old Windsor: the local picture

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

Common questions from Old Windsor clients

Is a smaller place like Old Windsor outside your area?

No. Places such as Old Windsor are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Portland Business Park, by Old Windsor?

Yes. Estates, retail parks and business parks around Old Windsor, Portland Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

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.

Can the warehouse stay open while you work?

Usually only the zone we’re working in has to close. Each zone reopens when the product can take traffic and the next zone follows.

When can forklifts run over new joint filler?

Cure times vary with the product and the conditions. We will give you a time for each zone before we start.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Do you repair broken joint edges?

Filling against broken edges doesn’t last. If the arrises have spalled, we’ll say they need repair before filling and set out how that affects the job.

What we can’t put right

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Level or flatness problems across the floor
  • Cracks across panels caused by settlement or overload
  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly.

What we seal

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

How the job changes by surface

Construction joints

Construction joints, sometimes called day joints, mark where one pour ended and the next began. They often see more movement than sawn joints and that shapes the choice of filler or sealant.

Retail and showroom floors

Polished and coated concrete floors in shops and showrooms show every joint. We aim for a tidy, flush finish that suits the floor, and we’ll confirm the colours available for the specified product.
