Questions from Long Wittenham

Is Long Wittenham in your area for floor joint sealing?

Yes, Long Wittenham is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Do you work for landlords with property near Appleford station?

Yes. We work for letting agents and landlords as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Can grout be replaced with sealant on a tiled floor?

Often, yes. We replace the grout along a suitable line with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.

What causes gaps between the floor and skirting?

Floors shrink and settle, especially in the first year or two and through the heating season. Rigid fillers split, so we use a flexible sealant.

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

Should I try DIY first?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Is caulk good enough for skirting?

Not where the floor moves or gets wet. It splits once the floor shifts. A flexible sealant is the better choice.

What affects the cost of floor joint sealing

There’s no set price list, because no two jobs are the same. What we look at:

  • Access and height
  • How much there is to do
  • Working hours on commercial sites
  • Mould in or behind the old joints

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Helping us quote

When you contact us, these details help:

  • Where the job is, and your postcode
  • Access, such as stairs, a lift or height
  • The rough size of the job

When something else is needed

In fairness, some problems need a different trade:

  • Movement too big for a sealant joint
  • Tiles that have lifted or broken
  • Cracked or broken concrete slabs

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

New homes and floors in Long Wittenham

Across Oxfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

Letting a property close to Appleford station? Then gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as Long Wittenham (Church of England) Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like Church of St Mary are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Keep floor cleaning water to a minimum at the edges
  • Keep caulk for dry, still joints only
  • Check the sealant is paintable before decorating
  • Check skirting joints after the heating season

Avoid flooding the floor when you clean. Less water at the edges helps the joints last.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier and stops it getting worse.

Surface by surface

Thresholds

Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product.

Concrete floor joints

Open concrete joints chip at the edges when wheels cross them. A sealed joint protects the edges and stops debris collecting.

Why act early in Long Wittenham

Dirt builds up in open joints. A neat sealed joint is easier to clean. In a small place like Long Wittenham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

How it works

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Long Wittenham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, the floor type, the gap and the traffic are checked.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. We apply the sealant in a colour that suits 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
  • Let us know about parking restrictions
  • Mention any tricky access
