Floor joint sealing near Crowthorne

About our floor joint sealing in Crowthorne

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out so water and dirt cannot get in. We work on wet room & bathroom floors, tiled floors and thresholds, and the jobs we see most are open joints around bathroom floor edges and failed joint filler in concrete floors.

Towns like Crowthorne have older streets and newer estates side by side, with new homes still going up on the edge of many towns. Whether a house is brand new or a few years old, sealant and floor joints are often the first snags to show.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Crowthorne questions

Do you work for landlords with property near Crowthorne station?

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.

Is floor joint sealing in Crowthorne guaranteed?

All our work, in Crowthorne and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can you seal over the old sealant?

No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Do you seal kitchen plinths to the floor?

Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone.

Do the sealants smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Are you insured?

Yes. We’re fully insured, with over 20 years’ experience in sealant work.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Have a cracking tiled floor checked before tiles break
  • Avoid sloshing water against skirting
  • Mark off resealed joints in warehouses
  • Look at floor joints each spring

Keep off the joint for the time we give you. Feet are usually fine before mopping or wheeled traffic so we will give you each time.

In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.

Different surfaces, different methods

Thresholds

Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.

Commercial floors

Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.

How we quote for floor joint sealing

The quote reflects the job in front of us. We take into account:

  • Which sealant suits the joint
  • Any working-time requirements on site
  • The old material and how stubborn it is
  • Mould in or behind the old joints

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • Where the job is, and your postcode
  • Roughly how big the job is
  • The type of property
  • Whether it has been sealed before

Need a quote? Please phone 0345 464 0079 or drop us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.

How it works

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a morning or an afternoon for most homes, depending on the size of the job. Parking in a town like Crowthorne is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor.
  5. Finally, we check the work and talk you through aftercare.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before

How to get a quote

New homes and floors in Crowthorne

Floors around Wokingham run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal.

Why it’s worth doing now in Crowthorne

The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before any work starts.
