How we handle floor joint sealing in Cowplain

Tiled floors can crack along the grout when there’s no room for movement. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant in a matching colour. If you have rigid edge joints in tiled floors and skirting caulk that keeps splitting, we can help, on commercial floors, skirting boards and concrete floor joints alike.

In and around Cowplain, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. Grout at the edge is removed and replaced with sealant.

Thresholds

Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.

Why deal with it now?

Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. In a smaller place like Cowplain, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Why us?

  • Colour picked to suit the job

Cowplain: your questions answered

Can you help a landlord with a rental near Rowlands Castle station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Is Cowplain within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before resealing.

What does floor joint sealing cost?

Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.

Can you use decorators’ caulk instead?

Because caulk cracks where there’s movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Is there a guarantee?

Yes. Each job is guaranteed for twelve months.

Do you work on commercial floors?

Yes. We reseal concrete floor joints in commercial and industrial units. The product is chosen for the traffic the floor takes.

DIY versus a professional finish

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

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 does not work out, we can still put it right.

When to call us in Cowplain

Water and dirt collect in open floor joints. In kitchens and bathrooms, mop water gets into the gap.

Look out for any of the following:

  • Chipped and open joints in warehouse floors
  • Open gaps along the bottom of skirting boards
  • Grout cracking in a straight line across a floor
  • Threshold joints that have opened or worn

Letting a property close to Rowlands Castle station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

What your quote should include

  • Is VAT in the price?
  • Is the old sealant removed completely?
  • What happens if they find a problem under the old sealant
  • What guarantee comes with the work

10 questions to ask before booking

Joints and finishes in Cowplain homes

Across Hampshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

For buildings such as The Hart Plain Church, floor and skirting joints in halls and kitchens wear like any others. If you look after a building such as Woodcroft Primary, floor and threshold joints in busy corridors wear quickly and are best resealed early.

How it works

On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. The work generally takes a morning or an afternoon for most homes. Parking around Cowplain is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. First, the floor type, the gap and the traffic are checked.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. The joint is tooled neatly and the cure time explained.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any previous sealing or DIY attempts
  • Mention any leaks or damp you’ve noticed

What sealant work cannot fix

In fairness, there are a few things sealant will not fix:

  • Loose, hollow or cracked tiles, which need a tiler
  • Movement too big for a sealant joint
  • Damaged concrete that needs breaking out and repairing

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
