Floor joint sealing near Merton Park

Joints and finishes in Merton Park homes

Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.

Merton Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Rented homes near South Merton station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a building such as Merton Park Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Floor joint sealing in Merton Park, done properly

Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is generally the better choice, which isn’t made to be painted. We’re often asked to deal with grout used at the floor edge instead of sealant and cracked caulk along skirting in bathrooms and kitchens, across concrete floor joints, thresholds and wet room & bathroom floors.

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.

There’s a 12-month guarantee on every job, large or small.

Quotes for floor joint sealing in Merton Park

Every job gets its own quote. This is what makes a difference:

  • The number of rooms or windows
  • Whether there’s mould to deal with
  • The type of sealant required
  • When we can work, for business premises

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we need to know

When you contact us, it’s useful to know:

  • Any access issues, like height or stairs
  • Any previous sealing or DIY work
  • Where the job is, and your postcode
  • Whether it’s a home or a business

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

How the job changes by surface

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.

Skirting boards

On painted skirting, we can use a flexible sealant that takes paint. Where water is involved, silicone is the better choice.

What we do, step by step

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a morning or an afternoon for most homes, depending on the size of the job. In Merton Park, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and smooth it.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • Keep children and pets away from the work area
  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in

Advice

When something else is needed

To be straight with you, some problems need a different trade:

  • Damaged concrete that needs breaking out and repairing
  • A tiled floor that needs relaying
  • Floors that are uneven or need levelling

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

What we seal

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

DIY sealant or a professional job?

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.

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

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Keep heavy wheels off new concrete joints until cured
  • Avoid caulk in bathrooms and kitchens
  • Act on grout cracks that run in a straight line
  • Use furniture pads near skirting

Check the joints after the first winter. If anything has opened, it’s easy to reseal before they spread.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.

Do you work for landlords with property near South Merton station?

When can I walk on the floor?

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

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Are you fully insured?

Yes. We are fully insured.

Can new sealant go over the old?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Do you use a paintable sealant?

It depends on the sealant, so let us know first. Joints that will be painted get a paintable product and wet areas get silicone.
