Trusted floor joint sealing in Cox Green

Floor joint sealing in Cox Green

Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors. We work on tiled floors, commercial floors and thresholds, and people most often call us about skirting that has pulled away from the floor and caulk that has cracked where the floor moves.

If you’ve bought a new home in or near Cox Green, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.

A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Our hiring checklist

Floor joint sealing around Cox Green

Across Windsor and Maidenhead, 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.

If you look after a church, hall or community building such as All Saints' Church, floor and skirting joints in halls and kitchens wear like any others. For site and facilities teams at buildings such as Wessex Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Your questions about floor joint sealing in Cox Green

Can you do floor joint sealing in Cox Green?

Yes. We work across London and the South East, and Cox Green is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear quote.

Can you help a landlord with a rental near Maidenhead station?

Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Can I add another job to the visit?

Yes. Several rooms, windows or areas can go on one quote.

Are you ARBOMaster approved?

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

What causes gaps between the floor and skirting?

Movement from drying timber and settling floors. Caulk tends to crack; a flexible sealant does not.

How long does the job take?

That depends on how much there is to do, but most jobs take a few hours for most rooms, longer for large commercial floors. We will give you a better idea when we quote.

Do you use a paintable sealant?

For painted skirting, we use a flexible product that can be painted. Silicone will not take paint, so we use it where the joint stays unpainted.

Can you match the sealant colour?

Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before any work starts.

Leave it or put it right?

An open concrete floor joint gets wider every time something heavy crosses it. Resealing it early protects the edges. Around Cox Green, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

How the job changes by surface

Concrete floor joints

Old filler, dust and debris are cleaned out of the joint, vacuuming them clean. Backing goes in where the depth needs controlling.

Skirting boards

On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is normally better.

Should I try it myself first?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Get cracks along tile grout lines looked at early
  • Keep floor cleaning water to a minimum at the edges
  • Use furniture pads near skirting
  • Check skirting joints after the heating season

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed.

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

What happens on the day

The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job normally takes a morning or an afternoon for most homes. Parking around Cox Green is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  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. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in
  • Mention any tricky access
