How to look after the new joints

After the cure time, these simple habits help:

  • Mark off resealed joints in warehouses
  • Keep caulk for dry, still joints only
  • Use a well-wrung mop rather than flooding the floor
  • Look at floor joints each spring

Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up before they spread.

Small gaps are quick to seal. Left alone, they collect dirt and widen over time.

Floor joint sealing for homes and businesses in Sandhurst

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant and stops dirt collecting. We work on skirting boards, wet room & bathroom floors and concrete floor joints, and the jobs we see most are rigid edge joints in tiled floors and gaps at thresholds between rooms.

Shops and business units around Sandhurst have floors that see a lot of traffic. Joints at thresholds and in tiled or concrete floors need resealing before the edges start to break up.

A one-year guarantee comes as standard, so you are covered after we have gone.

Different surfaces, different methods

Commercial floors

In commercial buildings, we can plan floor joint work around opening hours. We can arrange out-of-hours work where it’s needed.

Wet room and bathroom floors

Mop water gets into any open joint at the edge of a bathroom floor. A neat silicone joint keeps it out.

Should I try it myself first?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

The process

Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on the length of joint. A visit in Sandhurst needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Old caulk, grout or sealant is removed from the joint.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • On commercial sites, let us know about site rules
  • Clear items away from the joints we’re working on
  • Tell us about any water getting in

Advice

What affects the cost of floor joint sealing

Your quote is based on your job. We look at:

  • How much there is to do
  • The number of rooms or windows
  • Any working-time requirements on site
  • Which sealant suits the joint

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

When you call or email, these details help:

  • What the problem is, such as mould, gaps, leaks or cracking
  • A few photos by email, if you can
  • If it’s domestic, commercial or a hotel
  • Where the job is, and your postcode

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

What we are called out for in Sandhurst

Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.

Keep an eye out for these signs:

  • Rigid edge joints in tiled floors
  • Open joints that fill with dirt
  • Gaps opening between the floor and skirting
  • Gaps between floors and kitchen plinths

If you look after a church, hall or community building such as St George's Church, floor and skirting joints in halls and kitchens wear like any others.

Before booking anyone

  • Whether all the old sealant comes out first
  • What the quote includes, VAT included or not
  • How the surfaces are prepared before sealing
  • How hidden problems are handled

Choosing a sealant specialist

Why act early in Sandhurst

Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Sandhurst they get worse with every use. Now is the easy time to put it right.

We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Sandhurst: your questions answered

Do you work for landlords with property near Sandhurst station?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

Is floor joint sealing in Sandhurst guaranteed?

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

When can I walk on the floor?

Follow the cure time we give you. Light use comes first, cleaning and heavy traffic later, depending on the product.

Can you use decorators’ caulk instead?

Caulk is fine for dry joints that don’t move, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.

Where do you work from?

We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Can grout be replaced with sealant on a tiled floor?

Generally, yes. A crack along a grout line often means the floor needs room to move. We replace that grout with a flexible joint.

Why does the gap under my skirting keep coming back?

Normally it’s movement: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible bead keeps up with the movement.

Can you reseal concrete floor joints in an industrial unit?

Yes, including warehouses, units, shops and offices. Work can be planned around your hours, and out-of-hours work can be arranged.

Joints and finishes in Sandhurst homes

Floors around Bracknell Forest run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

Managing a site like Sandhurst School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. If you let a flat or house near Sandhurst station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
