Floor joint sealing for Thong homes and businesses

Floor joint sealing for homes and businesses in Thong

We seal floor joints in homes, offices and commercial buildings across Thong. Each job starts with looking at the floor and the gap, since that decides which sealant suits. Common call-outs are for gaps between floors and kitchen plinths and open joints that fill with dirt, across tiled floors, commercial floors and wet room & bathroom floors.

Somewhere as small as Thong, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Whatever the size of the job, you get the same one-year guarantee.

Landlords, agents and businesses in Thong

If you manage several properties in or around Thong, jobs at different addresses can be quoted together. Send us the addresses and the work at each.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

What happens on the day

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours, depending on the length of joint, depending on how much there is to do. In a small place like Thong, access is usually the main thing to plan. 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. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied and tooled.
  5. We check the joints and explain the aftercare.

Before we arrive

  • Mention if the joints have been sealed before
  • Keep children and pets away from the work area
  • Tell us about any water getting in

What affects the quote in Thong

For a quick quote, just ask. The main things that affect it are:

  • The type of sealant required
  • Any working-time requirements on site
  • The number and length of the joints
  • How many areas need sealing

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode

Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

When it is not the sealant

New sealant cannot fix everything, and we’d rather say so up front. It will not solve:

  • Subfloor problems that need a flooring contractor
  • Large cracks that need a surveyor
  • Damaged concrete that needs breaking out and repairing

If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

What we seal

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

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Questions from Thong

Is Thong within the area you cover?

Yes. Thong is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you help a landlord with a rental near Sole Street station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.

Are you ARBOMaster approved?

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

Can you use decorators’ caulk instead?

Caulk is fine for dry joints that don’t move, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.

How much does floor joint sealing cost in Thong?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Can sealant along the skirting be painted?

If you tell us beforehand, yes. We use a paintable flexible sealant on joints you plan to paint.

How long does floor joint sealing take?

Typically it takes a few hours for most rooms, longer for large commercial floors. Larger jobs naturally take longer, and we will tell you how long to expect.

What information do you need?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.

Floor joint sealing around Thong

Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

Community buildings like Church of St Peter and St Paul are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. For site and facilities teams at buildings such as Riverview Infant School, entrance and corridor floor joints take a lot of traffic. For landlords with property near Sole Street station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Concrete floor joints

Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and stops debris collecting.

Wet room and bathroom floors

Bathroom floor edges get wet at every clean. A flexible seal stops water running into the gap.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Avoid caulk in bathrooms and kitchens
  • Vacuum floor joints regularly to stop grit building up
  • Lift furniture rather than dragging it across joints
  • Check the sealant is paintable before decorating

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it while it cures.

Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
