About our floor joint sealing in Merton

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. If you are dealing with concrete floor joints that have broken down and skirting caulk that keeps splitting, we can help, whatever the surface.

Somewhere as small as Merton, 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.

Big or small, it’s backed by our 12-month guarantee in Merton and across Oxfordshire.

Merton questions

Can you do floor joint sealing in Merton?

Yes. Our work covers London and the South East, and Merton is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Do you work for landlords with property near Bicester Village station?

Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.

Can you seal where the floor meets the bath panel?

Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone.

Can I add another job to the visit?

Yes. Just list everything you need and we’ll quote it together.

Where do you work from?

We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Do you hold any approvals?

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

Can sealant along the skirting be painted?

If you tell us beforehand, yes. Joints that will be painted get a paintable product, and silicone elsewhere.

Which products do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

When it is not the sealant

We won’t take on work that won’t last, so here’s what sealant cannot put right:

  • Concrete repairs beyond the joint
  • Large cracks that need a surveyor
  • Bouncy or failing floorboards

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

Signs you need floor joint sealing in Merton

An open floor joint fills with dirt and water. In wet areas, water runs into the gap at every clean and can reach the subfloor.

Common reasons people contact us are:

  • Gaps opening between the floor and skirting
  • Gaps at thresholds between rooms
  • Grout cracking in a straight line across a floor
  • Cracked caulk along skirting in bathrooms and kitchens

Community buildings like Church of St Swithin are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

What your quote should include

  • Whether all the old sealant comes out first
  • What happens if they find a problem under the old sealant
  • Whether the sealant suits the joint
  • Who does the work, and how experienced they are

Our hiring checklist

How the job changes by surface

Commercial floors

Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.

Concrete floor joints

Old filler, dust and debris are cleaned out of the joint first. We fit backing where needed.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Look at floor joints each spring
  • Sweep along the edges of the floor
  • Lift furniture rather than dragging it across joints
  • Use a well-wrung mop rather than flooding the floor

Do not paint over silicone. If you plan to paint, we will use a paintable product.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and stops it getting worse.

DIY sealant or a professional job?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

What we do, step by step

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a morning or an afternoon for most homes, and the area is left clean. In a small place like Merton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Old caulk, grout or sealant is removed from the joint.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • Tell us if parking is tricky
  • Clear the area around the work
  • For business premises, tell us about site rules or sign-in
