Floor joint sealing near Cuddesdon

Floor joint sealing in Cuddesdon, done properly

Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone, which isn’t made to be painted. We work on wet room & bathroom floors, tiled floors and thresholds, and the jobs we see most are floor edges that trap water and grime and cracked grout where a tiled floor needs a movement joint.

Somewhere as small as Cuddesdon, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

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

How we quote for floor joint sealing

The quote reflects the job in front of us. We take into account:

  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site
  • The amount of work

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What to tell us for a quote

When you contact us, these details help:

  • What’s wrong with the joints now
  • The rough size of the job
  • Access, such as stairs, a lift or height
  • Pictures of the joints, sent by email

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.

Can I do it myself?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

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.

Floor joint sealing around Cuddesdon

Floors around Oxfordshire 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.

If you look after a church, hall or community building such as Church of All Saints, joints in its floors, skirtings and thresholds need resealing as they wear. For site and facilities teams at buildings such as Garsington Church of England Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Cuddesdon is about 5 miles south-east of Oxford, in Oxfordshire. From the centre of Cuddesdon to the outskirts, floor joint sealing is available for homes and businesses alike. Cuddesdon is one of 443 towns and villages in Oxfordshire we cover.

What happens on the day

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Cuddesdon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. We take out the cracked caulk, grout or old sealant.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor and smooth it.
  5. Finally, we check the work and talk you through aftercare.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know if you’ve seen damp or leaks
  • On commercial sites, let us know about site rules

Advice

Different surfaces, different methods

Concrete floor joints

Hard wheels break down the edges of open joints. A sealed joint protects the edges and keeps dirt out.

Skirting boards

Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing so the bead sits on a clean surface.

Looking after it afterwards

Aftercare is simple:

  • Act on grout cracks that run in a straight line
  • Sweep along the edges of the floor
  • Use furniture pads near skirting
  • Keep heavy wheels off new concrete joints until cured

Don’t paint over silicone. If the joint will be painted, tell us beforehand so we use a paintable sealant.

Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.

Why act early in Cuddesdon

Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a small place like Cuddesdon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Your questions about floor joint sealing in Cuddesdon

Can you do floor joint sealing in Cuddesdon?

Yes, Cuddesdon is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Is floor joint sealing in Cuddesdon guaranteed?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

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

Often, yes. Straight cracks in grout often show where a movement joint was needed. We replace that grout with a flexible joint.

Do you use a paintable sealant?

For painted skirting, we use a flexible product that can be painted. Silicone won’t take paint, so we use it where the joint stays unpainted.

Do you seal warehouse floor joints?

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor.

How soon can the floor be mopped?

That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over so there’s no guesswork.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Is it OK to seal over old sealant?

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
