Floor joint sealing in High Leigh

Floor joint sealing in High Leigh

Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out so water and dirt can’t get in. We’re often asked to deal with open gaps along the bottom of skirting boards and skirting caulk that keeps splitting, on thresholds, skirting boards and tiled floors.

For a small place like High Leigh, the journey and access are planned in advance, and the work itself is the same as on any site.

Each job carries a 12-month guarantee, large or small.

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

How it works

When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work normally takes a morning or an afternoon for most homes. In a small place like High Leigh, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. The joint is tooled neatly and the cure time explained.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • For business premises, tell us about site rules or sign-in
  • Keep pets and children clear of the area while we work

Advice

Surface by surface

Commercial floors

Commercial washrooms and kitchens have floor joints that get wet constantly. We reseal them with a sealant suited to wet areas.

Wet room and bathroom floors

Mop water gets into any open joint at the edge of a bathroom floor. A neat silicone joint keeps it out.

When it isn’t the sealant

Some problems need a builder, plumber or other trade rather than us:

  • Movement too big for a sealant joint
  • Cracked or broken concrete slabs
  • Leaks from a failed tanking system

If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

Where we work in High Leigh

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

Why deal with it now?

Dirt builds up in open joints, and they look untidy. A neat sealed joint is easier to clean and look tidier. Around High Leigh, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

What you get with us

  • Quality sealants from Arbo and Everbuild
  • Sealant colour chosen to suit
  • Sanitary silicone with an anti-fungal additive in wet areas
  • A choice of colours where the product allows

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Signs you need floor joint sealing in High Leigh

Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack.

It’s worth asking for a quote if you see:

  • Gaps at thresholds between rooms
  • Dirt and water collecting in open floor joints
  • Perimeter joints in tiled floors filled with grout
  • Concrete floor joints that have broken down

If you look after a church, hall or community building such as Church of St Catherine & St Paul, floor and skirting joints in halls and kitchens wear like any others.

Questions to ask before you book

  • How long the guarantee is
  • How long to leave it before use
  • How much experience the applicator has
  • What happens if they find a problem under the old sealant

Questions from High Leigh

Do you cover High Leigh for floor joint sealing?

Yes, High Leigh is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.

Do you work for landlords with property near Broxbourne station?

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.

Do you have insurance?

Yes, we’re fully insured for domestic and commercial work.

Does someone need to be in?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Can I choose the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Can you seal where the floor meets the bath panel?

Yes. These joints get wet every time the floor is cleaned, so a flexible silicone is the right choice.

Can new sealant go over the old?

No, and we never do. 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.

Will the old sealant be removed?

Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Joints and finishes in High Leigh homes

Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

For site and facilities teams at buildings such as Westfield Community Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Letting a property close to Broxbourne station? Then gaps at skirtings and thresholds are worth sealing between tenancies.
