About our floor joint sealing in Merstham

Tiled floors can crack along the grout when there’s no room for movement. We can turn a line of grout into a movement joint by replacing it with flexible sealant in a matching colour. If you have skirting that has pulled away from the floor and grout cracking in a straight line across a floor, we can put it right, on tiled floors, thresholds and commercial floors alike.

In a village or hamlet like Merstham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

All of our work is guaranteed for twelve months, in Merstham and everywhere else we cover.

Quotes for floor joint sealing in Merstham

There’s no set price list, because no two jobs are the same. What we look at:

  • The number and length of the joints
  • Whether the work is at height
  • Which sealant suits the joint
  • Mould in or behind the old joints

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What to tell us for a quote

When you call or email, it’s useful to know:

  • If it’s domestic, commercial or a hotel
  • How we’d reach the joints
  • What’s wrong with the joints now
  • Photos by email, if that’s easy

What the job involves on each surface

Commercial floors

Commercial washrooms and kitchens have floor joints that get wet constantly. They’re resealed with a flexible, water-resistant sealant.

Skirting boards

On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is normally better.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Don’t paint over silicone
  • Use a well-wrung mop rather than flooding the floor
  • Sweep along the edges of the floor
  • Cone off fresh joints until they’re ready

Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it.

A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and the edges sound.

When to call us in Merstham

Some floors were never given a perimeter gap or movement joint. It pushes against the walls and skirting as it expands, and the sealant or grout breaks.

People normally contact us after spotting something like this:

  • Gaps between floors and kitchen plinths
  • Cracked caulk along skirting in bathrooms and kitchens
  • Dirt and water collecting in open floor joints
  • Rigid edge joints in tiled floors

For site and facilities teams at buildings such as Merstham Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

  • Structural movement or subsidence
  • Leaks from a failed tanking system
  • Floors that are uneven or need levelling

How the visit works

You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for most rooms, longer for large commercial floors for a typical job. For a village or hamlet like Merstham, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Keep children and pets away from the work area
  • On commercial sites, let us know about site rules
  • Tell us if parking is tricky

Advice

Floor joint sealing around Merstham

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

If you look after a church, hall or community building such as Church of St Katharine, joints in its floors, skirtings and thresholds need resealing as they wear. Rented homes near Merstham station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Merstham: your questions answered

Do you cover Merstham for floor joint sealing?

Yes, Merstham is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Will you come out to Merstham?

Yes, Merstham is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Are you fully insured?

Yes, we’re fully insured for every job we do.

How long does the job take?

It depends on the size of the job, but as a guide it takes a morning or an afternoon for most homes. We will give you a better idea when we quote.

Is it worth trying it myself?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in.

Will I be able to paint over the new joint?

It depends on the sealant, so let us know first. Joints that will be painted get a paintable product.

Do you work on commercial floors?

Yes. Concrete floor joints in warehouses and units are part of our work. The product is chosen for the traffic the floor takes.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
