Trusted floor joint sealing in Sarratt

Common problems we fix in Sarratt

Caulk is the usual filler for skirting. It cracks where there’s movement or water, which is why so many skirting joints look broken.

If you can see any of these, it’s time to have the joints looked at:

  • Grout cracking in a straight line across a floor
  • Open joints that fill with dirt
  • Gaps opening between the floor and skirting
  • Threshold joints that have opened or worn

For site and facilities teams at buildings such as Sarratt Church of England Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What your quote should include

  • Is the old sealant removed completely?
  • Is VAT in the price?
  • When the joint can take water or movement
  • How the joint is cleaned and prepared

Choosing a sealant specialist

Floor joint sealing in Sarratt, done properly

Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints. If you are dealing with grout cracking in a straight line across a floor and gaps between floors and kitchen plinths, we can help, whatever the surface.

In a village or hamlet like Sarratt, 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.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Honest limits

We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:

  • Failed waterproofing under a wet room floor
  • Bouncy or failing floorboards
  • Structural movement or subsidence

Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Where we work in Sarratt

  • Thresholds
  • Tiled floors
  • Concrete floor joints
  • Skirting boards
  • Wet room & bathroom floors
  • Commercial floors

Why deal with it now?

Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. A flexible movement joint is the fix. Where a wall is exposed, as many are in small places like Sarratt, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Rather than a set price list, 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.

Sarratt questions

Is Sarratt in your area for floor joint sealing?

Yes, Sarratt is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

Do you work for landlords with property near Chorleywood station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

Do you offer different sealant colours?

We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

Is the work guaranteed?

Yes. There’s a 12-month guarantee on every job, large or small.

What do you need from me for a quote?

Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.

Is it worth trying 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 add a movement joint to a tiled floor?

Often, yes. Straight cracks in grout often show where a movement joint was needed. We replace that grout with a flexible joint.

Are you an approved applicator?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

How we quote for floor joint sealing

We quote each job individually. These are the things that affect it:

  • When we can work, for business premises
  • Mould in or behind the old joints
  • How many rooms, windows or areas are involved
  • Which sealant suits the joint

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Helping us quote

To help us quote quickly, let us know:

  • Where the job is, and your postcode
  • Photos by email, if that’s easy
  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business

We do not publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.

What the job involves on each surface

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it if it’s in the right place.

Skirting boards

Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing so the new sealant bonds.

Joints and finishes in Sarratt homes

Across Hertfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. That’s why the skirting and threshold joints need a flexible seal.

Letting a property close to Chorleywood station? Then gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a church, hall or community building such as Church of the Holy Cross, floor and skirting joints in halls and kitchens wear like any others.

How the visit works

When we arrive, we look over the joints with you first. We protect the surfaces around the joints before work begins. Most jobs take a few hours for most rooms, longer for large commercial floors. For a village or hamlet like Sarratt, 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 cleaned, vacuumed and backed where depth needs controlling.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

How to prepare

  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can
  • Plan for the work area to be out of bounds to pets and children

Aftercare tips

So the new joints stay in good condition:

  • Ask before painting over a sealed joint
  • Have a cracking tiled floor checked before tiles break
  • Keep caulk for dry, still joints only
  • Keep heavy wheels off new concrete joints until cured

Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal early on.

Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges.
