Floor joint sealing in Hertford

A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors in a colour to suit. We work on thresholds, concrete floor joints and wet room & bathroom floors, and people most often call us about threshold joints that have opened or worn and tiled floors with no room to move.

In a town like Hertford, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.

Whatever the size of the job, you get the same 12-month guarantee.

Common questions in Hertford

Is Hertford in your area for floor joint sealing?

Yes. We work across London and the South East, and Hertford is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.

Is floor joint sealing in Hertford guaranteed?

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

Is it OK to seal over old sealant?

No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

How long does floor joint sealing take?

A typical job takes a few hours, depending on the length of joint, including preparation and clearing up. Your quote will say how long we expect yours to take.

How much does floor joint sealing cost in Hertford?

Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.

Do you offer different sealant colours?

Most of the time, yes. We will explain which colours are available and agree one before work begins.

Where do you work from?

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

New homes and floors in Hertford

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

For buildings such as Hertford United Reform Church, floor and skirting joints in halls and kitchens wear like any others. For landlords with property near Hertford East station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Have a cracking tiled floor checked before tiles break
  • Avoid caulk in bathrooms and kitchens
  • Mark off resealed joints in warehouses
  • Keep dirt out of the joints

Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.

Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.

When to call us in Hertford

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges until the joint widens.

Keep an eye out for any of the following:

  • Open joints that fill with dirt
  • Skirting that has pulled away from the floor
  • Grout cracking in a straight line across a floor
  • Failed seals where bathroom floors meet baths and panels

Managing a site like Mill Mead Primary School? Then entrance and corridor floor joints take a lot of traffic.

What to look for in a quote

  • Whether the sealant suits the joint
  • How long the guarantee is
  • How the surfaces are prepared before sealing
  • Which colour the sealant will be

10 questions to ask before you book

Surface by surface

Commercial floors

Commercial floors take more traffic than most homes. The sealant is chosen for the traffic the floor takes.

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.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most rooms, longer for large commercial floors and we leave things clean and tidy. In Hertford, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Tell us about any water getting in
  • Clear the area around the work
  • Keep pets and children clear of the area while we work
