Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Sweep along the edges of the floor
  • Check the sealant is paintable before decorating
  • Do not slide heavy items over sealed joints
  • Avoid sloshing water against skirting

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

Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the floor safer.

Floor joint sealing in Rotherhithe, done properly

Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, then clean, back and seal the joint. We work on wet room & bathroom floors, concrete floor joints and skirting boards, and people most often call us about caulk that has cracked where the floor moves and tiled floors with no room to move.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.

A 12-month guarantee comes as standard.

How we quote for floor joint sealing

Your quote is based on your job. We take into account:

  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site
  • How easy the joints are to reach
  • The number and length of the joints

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Asking for a quote

Photos by email are helpful but not essential. Please mention:

  • Whether it has been sealed before
  • How many joints, rooms or windows are involved
  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

Floor joint sealing around Rotherhithe

Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

If you look after a building such as Alfred Salter Primary School, entrance and corridor floor joints take a lot of traffic. If you look after a church, hall or community building such as Holy Trinity Church, floor and skirting joints in halls and kitchens wear like any others.

Signs you need floor joint sealing in Rotherhithe

Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water so the gap reappears.

Look out for these signs:

  • Caulk that has cracked where the floor moves
  • Grout cracking in a straight line across a floor
  • Grout used at the floor edge instead of sealant
  • Skirting that has pulled away from the floor

Rotherhithe is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How to choose a mastic man

Why act early in Rotherhithe

Left open, concrete joints break down under traffic. A sealed joint supports the edges before they need a bigger repair. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why book with us

  • Anti-fungal silicone where joints get wet
  • Over 20 years’ experience
  • We’re fully insured
  • 12-month guarantee on every job

For landlords and businesses

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

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.

The process

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning or an afternoon for most homes. In Rotherhithe, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • On commercial sites, let us know about site rules
  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive

Can you add a movement joint to a tiled floor?

Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit.

Is caulk good enough for skirting?

Caulk is fine for dry joints that do not move, but it splits where the joint moves or gets wet. For most floor joints, we use a flexible sealant.

Can you match the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

Can you reseal concrete floor joints in an industrial unit?

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