Floor joint sealing in Poynders End

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

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.

About our floor joint sealing in Poynders End

The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We work on skirting boards, thresholds and tiled floors, and the jobs we see most are gaps opening between the floor and skirting and grout used at the floor edge instead of sealant.

For a small place like Poynders End, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

All of our work is guaranteed for twelve months, in Poynders End and everywhere else we cover.

What we do, step by step

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours, depending on the length of joint. Somewhere as small as Poynders End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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.

Thresholds

A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.

Skirting boards

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

Floors around Hertfordshire 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.

FAQs for Poynders End

Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Is Poynders End within the area you cover?

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.

Do you hold any approvals?

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

Can I choose the sealant colour?

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

Do you work on commercial floors?

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor and we’ll quote.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

How soon can the floor be mopped?

It depends on the product and the conditions. We give you the times for walking, cleaning and traffic when we finish so you can plan.

What causes gaps between the floor and skirting?

Movement from drying timber and settling floors. Caulk tends to crack; a flexible sealant doesn’t.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Get cracks along tile grout lines looked at early
  • Check the sealant is paintable before decorating
  • Use a well-wrung mop rather than flooding the floor
  • Keep dirt out of the joints

Avoid flooding the floor when you clean. Keeping the edges drier helps the sealant last longer.

Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.

Signs you need floor joint sealing in Poynders End

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges until the joint widens.

These are the problems we’re asked about most:

  • Floor edges that trap water and grime
  • Gaps at thresholds between rooms
  • Skirting caulk that keeps splitting
  • Tiled floors with no room to move

Schools such as Preston Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic.

Questions to ask before you book

  • How the joint is cleaned and prepared
  • How long to leave it before use
  • Who turns up on the day
  • Whether they’re fully insured
