  • A tiled floor that needs relaying
  • Damaged concrete that needs breaking out and repairing
  • Movement too big for a sealant joint

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Surfaces we seal

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

Floor joint sealing in Morden, done properly

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out. We work on concrete floor joints, thresholds and wet room & bathroom floors, and people most often call us about gaps opening between the floor and skirting and floor edges that trap water and grime.

London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Morden as anywhere.

Every job is covered by our one-year guarantee.

Joints and finishes in Morden homes

Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

If you look after a building such as Morden Primary School, entrance and corridor floor joints take a lot of traffic. Rented homes near St Helier station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. For buildings such as St Lawrence Church, floor and skirting joints in halls and kitchens wear like any others.

Morden is about 2 miles south of Wimbledon, in Greater London. Morden gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Morden is one of 764 towns and villages in Greater London where we work for floor joint sealing. Our London page covers work nearby, about 9 miles away.

Why it’s worth doing now in Morden

Floor joints left open collect dirt that’s hard to clean out and makes the floor look worn. A neat sealed joint is easier to clean and look tidier. In a flat in Morden, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Why Morden customers choose us

  • We leave the area clean and tidy
  • Sanitary silicone with an anti-fungal additive in wet areas
  • 12-month guarantee on every job
  • Any old sealant cut out fully, not covered over

Read our cost guide and what customers say.

What affects the cost of floor joint sealing

There’s no set price list, because jobs vary so much. What we look at:

  • Which sealant suits the joint
  • How much there is to do
  • Whether old sealant or filler has to be cut out
  • Any mould that needs treating

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Helping us quote

To make quoting easier, please include:

  • The type of property
  • What’s wrong with the joints now
  • The rough size of the job
  • Where the property is

For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work before giving you a price.

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Vacuum floor joints regularly to stop grit building up
  • Get cracks along tile grout lines looked at early
  • Keep heavy wheels off new concrete joints until cured
  • Look at floor joints each spring

Silicone sealant is not made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.

A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner.

What happens on the day

Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on the length of joint. In Morden, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  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.
  5. We check the joints and explain the aftercare.

Related advice

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Different surfaces, different methods

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. We seal them with a flexible sealant rather than caulk painted or coloured to match.

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 and we’ll say if the problem looks like more than the joint.

Morden: your questions answered

Is Morden in your area for floor joint sealing?

Yes, Morden is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.

Is parking a problem for a job in Morden?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Can you use decorators’ caulk instead?

Because caulk cracks where there’s movement or water. Floor edges move through the year, so a flexible sealant suits them better.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

How long before the joint can take traffic?

That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over.

What causes gaps between the floor and skirting?

Timber floors and skirting shrink and swell through the year. A flexible sealant closes the gap without cracking like caulk.

Can I choose the sealant colour?

In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
