Floor joint sealing in Slough, done properly

Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant in a matching colour. We work on thresholds, tiled floors and skirting boards, and people most often call us about cracked caulk along skirting in bathrooms and kitchens and grout used at the floor edge instead of sealant.

A place the size of Slough has new developments as well as older streets. Snags in sealant and floor joints often show in a new home’s first year or two.

Whatever the size of the job, it’s backed by our one-year guarantee.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Quotes for floor joint sealing in Slough

We quote each job individually. These are the things that affect it:

  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • Whether the work is at height
  • The type of sealant required

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • The problem you’ve noticed
  • Pictures of the joints, sent by email
  • Where the job is, and your postcode
  • Whether it’s a home or a business

We quote each job on its own. Just call 0345 464 0079 or send us an email with the details and send pictures if you have them.

Common problems we fix in Slough

When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, showing where a movement joint was needed.

It’s worth asking for a quote if you see:

  • Cracked grout where a tiled floor needs a movement joint
  • Open joints around bathroom floor edges
  • Floor edges that trap water and grime
  • Perimeter joints in tiled floors filled with grout

For site and facilities teams at buildings such as Herschel Grammar School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Before booking anyone

  • Whether you can choose the colour
  • Whether the sealant suits the joint
  • When the joint can take water or movement
  • Is the old sealant removed completely?

Our hiring checklist

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Keep heavy wheels off new concrete joints until cured
  • Sweep along the edges of the floor
  • Look at floor joints each spring
  • Avoid sloshing water against skirting

Keep heavy furniture from dragging across the joints. Dragging can tear the bead.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.

What happens on the day

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for most rooms, longer for large commercial floors. Commercial jobs in Slough can be planned out of hours where a building cannot close, while home visits are arranged within our normal working hours, Monday to Saturday.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  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. The joint is tooled neatly and the cure time explained.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Mention any parking rules near the property
  • Let us know if you’ve seen damp or leaks

Getting a quote

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or drop us an email.

What guarantee comes with floor joint sealing in Slough?

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

Can you add a movement joint to a tiled floor?

Often, yes, where it suits the floor. We remove the grout and seal the line with flexible sealant.

How long before the joint can take traffic?

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

Can sealant along the skirting be painted?

On joints you want to paint, yes. Silicone in bathrooms and kitchens cannot be painted.

Do you come to Slough?

We do. Slough is part of the area we cover, and the service is the same as everywhere else.

Is it OK to seal over old sealant?

No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
