Floor joint sealing in Blackmoor

Painted skirting can be sealed with a flexible product that can be painted over. In wet areas we’d normally use silicone, which isn’t made to be painted. We’re often asked to deal with rigid edge joints in tiled floors and tiled floors with no room to move, across thresholds, wet room & bathroom floors and commercial floors.

Older homes in small places like Blackmoor often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY sealant or a professional job?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Do you need floor joint sealing in Blackmoor?

When a tiled floor has no movement joints, the grout takes the strain. You’ll see a crack running along the grout, showing where a movement joint was needed.

Keep an eye out for any of the following:

  • Dirt and water collecting in open floor joints
  • Threshold joints that have opened or worn
  • Failed joint filler in concrete floors
  • Failed seals where bathroom floors meet baths and panels

Community buildings like St Matthew's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

How to choose a mastic man

What the job involves on each surface

Commercial floors

Commercial washrooms and kitchens have floor joints that get wet constantly. They’re resealed with a flexible, water-resistant sealant.

Concrete floor joints

Open concrete joints chip at the edges when wheels cross them. A sealed joint protects the edges and keeps dirt out.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most rooms, longer for large commercial floors. For a village or hamlet like Blackmoor, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We look at the gap and the floor type and agree the right sealant.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints
  • Try not to wet indoor joints just before the visit

Aftercare tips

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

  • Look at floor joints each spring
  • Cone off fresh joints until they’re ready
  • Keep caulk for dry, still joints only
  • Do not paint over silicone

Follow the cure time before walking on or cleaning the joint. Feet are generally fine before mopping or wheeled traffic so we will give you each time.

A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner and the edges sound.

Your questions about floor joint sealing in Blackmoor

Is Blackmoor in your area for floor joint sealing?

Yes. Our work covers London and the South East, and Blackmoor is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.

Is Blackmoor within the area you cover?

Yes. Blackmoor is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you add a movement joint to a tiled floor?

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

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Do you offer different sealant colours?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Do you have insurance?

Yes, we’re fully insured for domestic and commercial work.

Can new sealant go over the old?

No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Can tenants book the work?

Yes. Check with your landlord; we can send the quote to them too.

When it isn’t the sealant

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Failed waterproofing under a wet room floor
  • Floors that are uneven or need levelling
  • Damaged concrete that needs breaking out and repairing

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

Floor joint sealing around Blackmoor

Across Hampshire, 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. The joint at the skirting or threshold has to allow for that.

If you let a flat or house near Liss station, a tidy floor and skirting joint helps a rental look ready for the next tenant. Schools such as St Matthew's Church of England Aided Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
