Floor joint sealing in Lyneham

Different surfaces, different methods

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint.

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking painted or coloured to match.

Floor joint sealing in Lyneham, done properly

A threshold joint has to cope with feet, movement and sometimes water. We seal them with a flexible sealant suited to the floor finishes either side. If you have gaps at thresholds between rooms and floor edges that trap water and grime, we can help, on skirting boards, commercial floors and concrete floor joints alike.

Work in a small place like Lyneham just needs the journey and access planning, and once on site, the job is the same as anywhere.

Whatever the size of the job, it’s backed by our 12-month guarantee.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Floor joint sealing in Lyneham: local notes

Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

In and around Lyneham, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint. For landlords with property near Shipton station, gaps at skirtings and thresholds are worth sealing between tenancies.

Landlords, agents and businesses in Lyneham

Landlords and agents in Lyneham can book us as well as householders. Sealant work between tenants keeps a property looking cared for.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

How to look after the new joints

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

  • Mark off resealed joints in warehouses
  • Do not fill floor joints with caulk where they move or get wet
  • Have a cracking tiled floor checked before tiles break
  • Vacuum floor joints regularly to stop grit building up

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 the edges sound.

Questions from Lyneham

Do you work for landlords with property near Shipton station?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.

Can you do floor joint sealing in Lyneham?

Yes, Lyneham is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Why not just use caulk?

Caulk works on still, dry joints, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.

What causes gaps between the floor and skirting?

Movement from drying timber and settling floors pulls the skirting and floor apart. Caulk tends to crack; a flexible sealant doesn’t.

Do you remove the old sealant?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

How long before the joint can take traffic?

We give you a cure time for each joint. Feet are normally fine first, then mopping, then heavy wheels, depending on the product.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Why deal with it now?

Putting new grout into a crack that keeps reappearing doesn’t last. The movement is still there, so the grout fails again. A flexible movement joint is the fix. In a small place like Lyneham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.

What we do, step by step

We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on the length of joint. In a small place like Lyneham, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied 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 about parking restrictions
  • Let us know if you’ve seen damp or leaks
