Floor joint sealing in Catslip

When it is not the sealant

We’d rather tell you now than do work that will not last, so these are the limits:

  • Concrete repairs beyond the joint
  • Large cracks that need a surveyor
  • Subfloor problems that need a flooring contractor

Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

What we seal

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

Floor joint sealing in Catslip, done properly

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out and stops dirt collecting. If you have concrete floor joints that have broken down and gaps opening between the floor and skirting, we can put it right.

Older homes in small places like Catslip often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

What affects the cost of floor joint sealing

Your quote is based on your job. We look at:

  • The number of rooms or windows
  • When we can work, for business premises
  • Which sealant suits the joint
  • The number and length of the joints

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before we start.

Helping us quote

You do not need to know the technical terms. Just tell us:

  • How we’d reach the joints
  • Any previous sealing or DIY work
  • Whether it’s a home or a business
  • Photos by email, if that’s easy

We quote each job on its own. Simply ring 0345 464 0079 or send us an email and describe the job, and photos are welcome.

Catslip questions

Will you come out to Catslip?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Henley-On-Thames station?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Do you offer different sealant colours?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Is caulk good enough for skirting?

Not where the floor moves or gets wet. It splits once the floor shifts and the gap reopens. A flexible sealant lasts longer there.

What do you need from me for a quote?

Tell us what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.

Do I need to be at home?

That depends on where the joints are. Inside work needs someone to give us access.

Why has a gap opened under my skirting?

It’s normally the floor moving: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible bead keeps up with the movement.

What the job involves on each surface

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.

Commercial floors

Shops, offices, warehouses and units all have floor joints that need sealing. We talk through the traffic and choose a sealant suited to it.

What floor joint sealing looks like in Catslip

Across Oxfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.

Community buildings like Church of St Bartholomew are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Letting a property close to Henley-On-Thames station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant. Managing a site like Nettlebed Community School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Why act early in Catslip

Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. Around Catslip, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit is usually more efficient than separate visits. We will give you a clear price for the lot.

How the visit works

All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a morning or an afternoon for most homes. Somewhere like Catslip needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied and smooth it.
  5. We check the joints and explain the aftercare.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Clear items away from the joints we’re working on
  • Keep pets and children clear of the area while we work

Advice

Can I do it myself?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, 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 won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Landlords, agents and businesses in Catslip

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
