If you look after a building such as The Winston Churchill School A Specialist Sports College, entrance and corridor floor joints take a lot of traffic. Community buildings like St John's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

About our floor joint sealing in St John's

Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is normally the better choice because it handles water. Typical jobs include grout used at the floor edge instead of sealant and gaps between floors and kitchen plinths, across concrete floor joints, thresholds and skirting boards.

For a new home in or near St John's, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Common questions in St John's

Do you cover St John's for floor joint sealing?

Yes. We work across London and the South East, and St John's is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.

Is St John's within the area you cover?

Yes. St John's is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How long does the job take?

A typical job takes a few hours for most rooms, longer for large commercial floors, including preparation and clearing up. We’ll confirm how long when we quote.

Is caulk good enough for skirting?

Not where the floor moves or gets wet. Caulk cracks as the floor moves and the gap reopens. A flexible sealant is the better choice.

Are you insured?

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

Is it OK to seal over old sealant?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Can sealant along the skirting be painted?

On joints you want to paint, yes. Silicone in bathrooms and kitchens cannot be painted.

Do you seal floor joints in bathrooms and kitchens?

Yes. We cut out any old sealant or caulk and reseal with flexible silicone, colour-matched where it shows.

Landlords, agents and businesses in St John's

We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

If you manage several properties in or around St John's, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.

Do you need floor joint sealing in St John's?

Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away and the joint gets wider.

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

  • Open gaps along the bottom of skirting boards
  • Skirting caulk that keeps splitting
  • Gaps at thresholds between rooms
  • Open joints that fill with dirt

Rented homes near Woking station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

What to look for in a quote

  • Is VAT in the price?
  • How the joint is cleaned and prepared
  • Is the old sealant removed completely?
  • What happens if the job turns out different

Choosing a sealant specialist

How we quote for floor joint sealing

Your quote is based on your job. We take into account:

  • Working hours on commercial sites
  • Mould in or behind the old joints
  • The product the joint needs
  • How many rooms, windows or areas are involved

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Asking for a quote

Photos by email are helpful but not essential. Try to tell us:

  • What’s wrong with the joints now
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode

Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job.

Leave it or put it right?

Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. In an older home around St John's, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

What you get with us

  • Tidy, careful work
  • White, clear, grey or another colour, product permitting
  • Arbo and Everbuild products
  • Experience in homes, commercial sites and hotels

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What we cannot put right

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

  • Cracked or broken concrete slabs
  • A tiled floor that needs relaying
  • Bouncy or failing floorboards

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

What we seal

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

What we do, step by step

Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning or an afternoon for most homes. Parking around St John's is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied.
  5. We check the joints and explain the aftercare.

How to prepare

  • Keep pets and children clear of the area while we work
  • Clear items away from the joints we are working on
  • Let us know if you’ve seen damp or leaks
