About our floor joint sealing in Holwell

Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors so the joint stays neat. Typical jobs include gaps between floors and kitchen plinths and caulk that has cracked where the floor moves, across tiled floors, thresholds and commercial floors.

Work in a small place like Holwell just needs the journey and access planning, and once on site, the job is the same as anywhere.

Every job is covered by a 12-month guarantee.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected.

Where do you work from?

Our base is in Crawley, and we work across South East England, London and Scotland.

Do you use a paintable sealant?

On joints you want to paint, yes. Silicone doesn’t take paint.

Do you seal floor joints in bathrooms and kitchens?

Yes. These joints get wet every time the floor is cleaned, so we seal them with silicone suited to wet areas.

Can I add another job to the visit?

Yes, we can. More than one area can go on one quote.

Can you seal over the old sealant?

No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Floor joint sealing in Holwell: local notes

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.

For landlords with property near Hitchin station, a tidy floor and skirting joint helps a rental look ready for the next tenant. Schools such as The Priory School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

How the job changes by surface

Concrete floor joints

Hard wheels break down the edges of open joints. A sealed joint protects the edges.

Commercial floors

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

When to call us in Holwell

Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting, then close again in damper months.

Common reasons people contact us are:

  • Open joints around bathroom floor edges
  • Gaps at thresholds between rooms
  • Grout cracking in a straight line across a floor
  • Cracked caulk along skirting in bathrooms and kitchens

If you look after a church, hall or community building such as Church of St Peter (C of E) at Corner with Holwell Road, joints in its floors, skirtings and thresholds need resealing as they wear.

10 questions to ask before you book

Landlord and commercial work in Holwell

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

What we cannot put right

In fairness, some problems need a different trade:

  • Floors that are uneven or need levelling
  • Tiles that have lifted or broken
  • Cracked or broken concrete slabs

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

What we seal

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

Leave it or put it right?

Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. Older cottages and farmhouses around Holwell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Aftercare tips

Simple care keeps the joints in good condition. Our advice:

  • Look at floor joints each spring
  • Mark off resealed joints in warehouses
  • Keep floor cleaning water to a minimum at the edges
  • Sweep along the edges of the floor

Follow the cure time before walking on or cleaning the joint. Light foot traffic is usually fine sooner than wet cleaning or wheels.

Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact and the surface smoother.

How the visit works

On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work usually takes a few hours, depending on the length of joint. In a small place like Holwell, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. We take out any old caulk, sealant or grout along the line.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Keep children and pets away from the work area
  • Tell us about any previous sealing or DIY attempts
