  • Cracked or broken concrete slabs

About our floor joint sealing in Boreham Street

Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out. We work on tiled floors, thresholds and wet room & bathroom floors, and the jobs we see most are chipped and open joints in warehouse floors and cracked caulk along skirting in bathrooms and kitchens.

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

All our work is covered by a 12-month guarantee.

What floor joint sealing looks like in Boreham Street

Across East Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

In and around Boreham Street, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.

Do you need floor joint sealing in Boreham Street?

A new floor or screed shrinks and settles as it dries. Gaps at the edges appear in the first year or so and anything rigid cracks.

These are the problems we’re asked about most:

  • Tiled floors with no room to move
  • Open gaps along the bottom of skirting boards
  • Concrete floor joints that have broken down
  • Open joints that fill with dirt

If you let a flat or house near Normans Bay station, gaps at skirtings and thresholds are worth sealing between tenancies.

Before you book anyone

  • How long to leave it before use
  • Whether all the old sealant comes out first
  • What guarantee comes with the work
  • What happens if they find a problem under the old sealant

Choosing a sealant specialist

Can I do it myself?

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

How the visit works

The work is kept neat and contained to the area we are working on. Expect the work to take a few hours for most rooms, longer for large commercial floors, and we tell you how long to leave it before we go. In a small place like Boreham Street, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at the gap and the floor type and agree the right sealant.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  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
  • Let us know about stairs, lifts or work at height
  • Clear items away from the joints we are working on

Common questions in Boreham Street

Do you cover Boreham Street for floor joint sealing?

Yes. We work across London and the South East, and Boreham Street is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

Do you work for landlords with property near Normans Bay station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

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.

How do I get a quote for floor joint sealing in Boreham Street?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.

Will there be a smell?

There can be a smell while the sealant cures. Ventilation helps.

Do you seal warehouse floor joints?

Yes, including warehouses, units, shops and offices. Work can be planned around your hours, and out-of-hours work can be arranged.

Will I be able to paint over the new joint?

Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone is not made to be painted, so it’s kept for wet areas and unpainted joints.

Is it OK to seal over old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Leave it or put it right?

An open concrete floor joint gets wider every time something heavy crosses it. Resealing it early protects the edges and keeps the damage down. Around Boreham Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
