Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Floor joint sealing for homes and businesses in Westcot

Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is normally the better choice. If you have cracked caulk along skirting in bathrooms and kitchens and failed seals where bathroom floors meet baths and panels, we can put it right, whatever the surface.

Around Westcot, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

Each job carries a 12-month guarantee.

When to call us in Westcot

New floors settle once they’re in use. The edges pull away from the skirting and anything rigid cracks.

These are the problems we’re asked about most:

  • Tiled floors with no room to move
  • Gaps at thresholds between rooms
  • Skirting caulk that keeps splitting
  • Failed seals where bathroom floors meet baths and panels

For site and facilities teams at buildings such as The Ridgeway Church of England (C) Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What to look for in a quote

  • Is the old sealant removed completely?
  • How the surfaces are prepared before sealing
  • What happens if they find a problem under the old sealant
  • The length of the guarantee

Our hiring checklist

When something else is needed

A few problems are outside what sealant work can do:

  • Movement too big for a sealant joint
  • A tiled floor that needs relaying
  • Water getting under the tiles from elsewhere

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

What we seal

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

How we quote for floor joint sealing

The price is agreed before any work begins. It’s based on:

  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints
  • The product the joint needs
  • How easy the joints are to reach

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

What we need to know

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Roughly how big the job is
  • Photos by email, if that is easy
  • Where the job is, and your postcode
  • The problem you’ve noticed

We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or drop us an email and describe the job, and photos are welcome.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Mark off resealed joints in warehouses
  • Have a cracking tiled floor checked before tiles break
  • Sweep along the edges of the floor
  • Keep floor cleaning water to a minimum at the edges

Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. Resealing early keeps it out.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

For anyone letting property in or around Westcot, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

What floor joint sealing looks like in Westcot

Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

If you look after a church, hall or community building such as Church of the Holy Rood, floor and skirting joints in halls and kitchens wear like any others.

What we do, step by step

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a morning or an afternoon for most homes. Somewhere like Westcot needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park.

  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor.
  5. We check the joints and explain the aftercare.

  • Keep children and pets away from the work area

Westcot: your questions answered

Will you come out to Westcot?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is Westcot in your area for floor joint sealing?

Yes. We work across London and the South East, and Westcot is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Do you have insurance?

Yes. We are fully insured, and we have been doing sealant work for more than 20 years.

Can you use decorators’ caulk instead?

Caulk is fine for dry joints that do not move, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.

My floor grout keeps cracking in a line. Can you help?

Often, yes, at the edges and along suitable lines. The grout is raked out and replaced with a flexible sealant in a colour to suit.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in.

Which products do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

How long does the job take?

That depends on how much there is to do, but as a guide it takes a morning or an afternoon for most homes. We’ll tell you when we quote.
