Floor joint sealing in Sandford-on-Thames, done properly

The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk normally cracks where there’s movement, so we close it with a flexible sealant instead. If you have skirting caulk that keeps splitting and failed seals where bathroom floors meet baths and panels, we can help.

In a village or hamlet like Sandford-on-Thames, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

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

  • Concrete floor joints that have broken down
  • Gaps opening between the floor and skirting

10 questions to ask before booking

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Mark off resealed joints in warehouses
  • Use furniture pads near skirting
  • Don’t paint over silicone
  • Get cracks along tile grout lines looked at early

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

Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen.

What affects the cost of floor joint sealing

The quote reflects the job in front of us. We look at:

  • Which sealant suits the joint
  • The size of the job
  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • How we’d reach the joints
  • Roughly how big the job is
  • Whether it has been sealed before
  • Whether it’s a home or a business

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

When something else is needed

It helps to know what we cannot do too:

  • Bouncy or failing floorboards
  • Water getting under the tiles from elsewhere
  • A tiled floor that needs relaying

If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

What we seal

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

How it works

When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for most rooms, longer for large commercial floors. In a small place like Sandford-on-Thames, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

How to prepare

  • Mention if the joints have been sealed before
  • Mention any tricky access
  • Mention any parking rules near the property

Advice

What floor joint sealing looks like in Sandford-on-Thames

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. That’s why the skirting and threshold joints need a flexible seal.

If you look after a church, hall or community building such as Church of St Andrew, joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like John Henry Newman Academy? Then entrance and corridor floor joints take a lot of traffic.

Your questions about floor joint sealing in Sandford-on-Thames

Do you work for landlords with property near Radley station?

Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Do you cover smaller places like Sandford-on-Thames?

Yes, Sandford-on-Thames is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Where are you based?

Mr Mastic is based in Crawley. We cover Sandford-on-Thames and the rest of Oxfordshire, along with the rest of our area.

Can you use decorators’ caulk instead?

Not where the floor moves or gets wet. Caulk cracks as the floor moves. A flexible sealant lasts longer there.

Is it messy?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Do you work on commercial floors?

Yes. Concrete floor joints in warehouses and units are part of our work. We’ll talk through the traffic and choose a sealant suited to it.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you are set on DIY, put the effort into 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.
