Floor joint sealing in Southcote

Floor joint sealing in Southcote

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on commercial floors, wet room & bathroom floors and skirting boards, and the jobs we see most are caulk that has cracked where the floor moves and cracked grout where a tiled floor needs a movement joint.

In and around Southcote, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.

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

How the job changes by surface

Concrete floor joints

Concrete floors have sawn or formed joints to control cracking. We reseal them with a floor-joint product suited to the traffic.

Wet room and bathroom floors

In a wet room, the floor-to-wall joint is a key line of defence. We reseal it with a flexible silicone suited to wet areas, and we’ll tell you if the leak seems to come from elsewhere.

The process

At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for most rooms, longer for large commercial floors, depending on the amount of work. Parking around Southcote is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Old caulk, grout or sealant is removed from the joint.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Getting ready for the visit

  • Clear items away from the joints we are working on
  • Mention if the joints have been sealed before
  • For business premises, tell us about site rules or sign-in

Advice

What sealant work cannot fix

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Cracked or broken concrete slabs
  • Movement too big for a sealant joint
  • A tiled floor that needs relaying

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

Surfaces we seal

  • Tiled floors
  • Commercial floors
  • Concrete floor joints
  • Skirting boards
  • Thresholds
  • Wet room & bathroom floors

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Mark off resealed joints in warehouses
  • Act on grout cracks that run in a straight line
  • Don’t paint over silicone
  • Do not fill floor joints with caulk where they move or get wet

Keep off the joint for the time we give you. Light foot traffic is generally fine sooner than wet cleaning or wheels.

A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner and the edges sound.

Joints and finishes in Southcote homes

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

Managing a site like Manor Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. If you look after a church, hall or community building such as St Matthew's, joints in its floors, skirtings and thresholds need resealing as they wear. If you let a flat or house near Reading Green Park station, gaps at skirtings and thresholds are worth sealing between tenancies.

Why it’s worth doing now in Southcote

Left open, concrete joints break down under traffic. A sealed joint supports the edges. Around Southcote, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

FAQs for Southcote

I let a flat near Reading Green Park station. Can you help?

Yes, rental work is part of what we do. You can ring 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.

Will you come out to Southcote?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you do several jobs on one visit?

Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

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.

Do you take out the old sealant first?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

How much does floor joint sealing cost in Southcote?

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

How long does the job take?

A typical job takes a morning or an afternoon for most homes, including preparation and clearing up. We will confirm how long when we quote.

Will it make a mess?

Tidy work is part of the job. Nearby surfaces are protected.
