About our floor joint sealing in Caversham

We have been sealing commercial joints since 2005. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member holding public liability insurance. Finished floor joints in Caversham carry our 12-month guarantee. If you’re dealing with a rough ride across broken joints and unfilled floor joints collecting dirt and grit, we can put it right, on construction joints, joints along racking aisles and loading bays alike. One point of contact handles commercial sealant work in Caversham from the first photos to the final walk-round, for single jobs and planned programmes alike.

Car parks and yards in towns like Caversham take tyre loads and, in winter, de-icing salt. Catching a joint before its edges break is the simpler route.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common problems we fix in Caversham

An ageing filler or sealant can go brittle and split, particularly where cleaning machines and traffic work it daily. Once it has gone hard or come loose, it protects nothing.

Clients typically get in touch after noticing something like this:

  • Dock area joints that have failed first
  • Filler that has parted from one face
  • Saw-cut joints left open and packed with grit
  • Soft sealant dragged out of trafficked joints

University campuses such as University of Reading (to the south of Caversham) have car parks, paved walkways and building elevations with movement joints.

Questions to ask before you appoint anyone

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Treat loading bay joints first if they’re failing
  • Allow for topping up joints as a new slab settles
  • Keep photos of joints that look like they’re failing
  • Tell us about strong cleaning chemicals before we quote

If a joint we filled starts to break up within 12 months, tell us and we will arrange a look. Beyond that, an inspection once or twice a year catches failing joints early.

Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder, so it pays to act at the first signs.

How the job changes by 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 confirm which colours the product comes in.

Semi-rigid joint fillers

A semi-rigid fill can separate along one side while a slab is still shrinking. That is normally dealt with by topping up later and we will flag it at quote stage.

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Most work in Caversham is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  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

  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs

Advice

FAQs: Caversham

Must our site in Caversham stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Do you cover business parks and estates near Caversham, such as The Station Shopping Park?

Yes. Our area takes in Caversham and its surroundings, with estates and business parks such as The Station Shopping Park included. A few photos and the unit address let us price the work.

Can you phase floor joint work around operations?

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

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.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you work in Caversham?

Yes. We take on work across Caversham.

What happens if the joint edges are damaged?

We check the edges as part of the survey. Where they have broken away, we will tell you before quoting the filling so the filling isn’t wasted.

Leave it or put it right?

Waiting for a site-wide shutdown often means the joints keep getting worse. Zone by zone, the worst aisles can be dealt with now and the remainder follows on a plan that suits you. In a town such as Caversham, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Resealing them early protects the building behind.

A quote for floor joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Level or flatness problems across the floor
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • Worn screed or surface finishes

If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

Joints and surfaces we work on

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

Central London is about 38 miles from Caversham. The roads out of London are lined with trade parks and distribution sheds.
