Trusted floor joint sealing in Longstock

Floor joint sealing in Longstock

Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints using a product that suits the floor. Typical jobs include dirt and water collecting in open floor joints and open gaps along the bottom of skirting boards, across concrete floor joints, skirting boards and tiled floors.

Around Longstock, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

Your job is guaranteed for a year, as with all our work.

Signs you need floor joint sealing in Longstock

Caulk is the usual filler for skirting. It cracks where there’s movement or water, which is why so many skirting joints look broken.

Any of these means the joints need attention:

  • Skirting caulk that keeps splitting
  • Open joints that fill with dirt
  • Failed seals where bathroom floors meet baths and panels
  • Open gaps along the bottom of skirting boards

Community buildings like Church of St Mary are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Your questions about floor joint sealing in Longstock

Will you come out to Longstock?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What guarantee comes with floor joint sealing in Longstock?

Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Is it OK to seal over old sealant?

No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

What does floor joint sealing cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.

Are you insured?

Yes, we’re fully insured.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Can you do several jobs on one visit?

Yes, we can. More than one area can be quoted together.

Why act early in Longstock

Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant moves with the floor, so the joint stays closed. In a small place like Longstock, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What floor joint sealing looks like in Longstock

Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

If you look after a building such as Test Valley School, entrance and corridor floor joints take a lot of traffic.

How to look after the new joints

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

  • Keep floor cleaning water to a minimum at the edges
  • Mark off resealed joints in warehouses
  • Lift furniture rather than dragging it across joints
  • Keep dirt out of the joints

Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal.

A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.

How the visit works

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning or an afternoon for most homes. Somewhere as small as Longstock, access is often the only tricky part. 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. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor.
  5. Finally, we check the work and talk you through aftercare.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Let us know about stairs, lifts or work at height
  • Mention any parking rules near the property

Should I try it myself first?

If you do try it yourself, take your time over the 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.

A careful DIYer can reseal a simple joint, 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.

How the job changes by surface

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.

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it if it’s in the right place.
