When it is not the sealant

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Structural movement or subsidence
  • Loose, hollow or cracked tiles, which need a tiler
  • Damaged concrete that needs breaking out and repairing

If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Surfaces we seal

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

Floor joint sealing in Agar Town

Across Agar Town, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, since that decides which sealant suits. If you have failed seals where bathroom floors meet baths and panels and rigid edge joints in tiled floors, we can put it right, whatever the surface.

New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

A one-year guarantee comes with the work, just as it does everywhere we cover.

The process

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most rooms, longer for large commercial floors. For a job in Agar Town, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  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. We apply a flexible sealant suited to the floor and tooled.
  5. We check the joints and explain the aftercare.

How to prepare

  • Mention any parking rules near the property
  • Clear the area around the work
  • Mention any leaks or damp you’ve noticed

Signs you need floor joint sealing in Agar Town

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges and the joint gets wider.

The most common problems we see are:

  • Rigid edge joints in tiled floors
  • Dirt and water collecting in open floor joints
  • Open joints around bathroom floor edges
  • Chipped and open joints in warehouse floors

If you let a flat or house near Camden Road station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Our hiring checklist

What affects the cost of floor joint sealing

We don’t publish a price list, because jobs vary so much. What we look at:

  • The size of the job
  • The product the joint needs
  • The number of rooms or windows
  • Whether the work is at height

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Asking for a quote

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

  • If it’s domestic, commercial or a hotel
  • Where the property is
  • A few pictures by email, if you can
  • How many joints, rooms or windows are involved

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Can I do it myself?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Why it’s worth doing now in Agar Town

Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. Replacing that line with flexible sealant gives it somewhere to go. 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 for homes in Agar Town.

Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

What you get with us

  • You choose the colour before work begins
  • One-year guarantee on every job
  • Any old sealant cut out fully, not covered over
  • Sealant colour chosen to suit

Questions from Agar Town

Can parking be tricky for a visit in Agar Town?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Is Agar Town in your area for floor joint sealing?

Yes. Our work covers London and the South East, and Agar Town is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Where do you work from?

Mr Mastic is based in Crawley. Our applicators cover Agar Town.

Is it worth trying it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Can you add a movement joint to a tiled floor?

Often, yes. We replace the grout along a suitable line with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.

Why does the gap under my skirting keep coming back?

Floors shrink and settle, especially in the first year or two and through the heating season pulls the skirting and floor apart. Rigid fillers split, so we use a flexible sealant.

Do you hold any approvals?

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

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

New homes and floors in Agar Town

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Floors around Greater London 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.

If you look after a church, hall or community building such as All Saints, joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like Abacus Belsize Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Keeping the joints in good condition

Looking after new joints is easy:

  • Avoid sloshing water against skirting
  • Use furniture pads near skirting
  • Vacuum floor joints regularly to stop grit building up
  • Look at floor joints each spring

Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.

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