- Open joints that fill with dirt
How the job changes by surface
Skirting boards
Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking painted or coloured to match.
Wet room and bathroom floors
Bathroom floor edges get wet at every clean. A flexible seal stops water running into the gap.
Floor joint sealing in Sewardstone, done properly
Where skirting is painted, we can use a flexible sealant that takes paint. For bathrooms and kitchens, silicone is usually the better choice because it handles water. We work on concrete floor joints, tiled floors and thresholds, and common reasons people get in touch are grout cracking in a straight line across a floor and dirt and water collecting in open floor joints.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Sewardstone and beyond.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a morning or an afternoon for most homes. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Sewardstone. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we check the joint and the floor and agree which sealant suits it.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Advice
Why deal with it now?
Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. A flexible movement joint is the fix. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Sewardstone.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
Why us?

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid caulk in bathrooms and kitchens
- Keep floor cleaning water to a minimum at the edges
- Cone off fresh joints until they’re ready
- Vacuum floor joints regularly to stop grit building up
Keep heavy furniture from dragging across the joints. Dragging can tear the bead especially in the first few days.
Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further.
Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Failed waterproofing under a wet room floor
- Subfloor problems that need a flooring contractor
- Tiles that have lifted or broken
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Sewardstone questions
Is Sewardstone in your area for floor joint sealing?

I let a flat near Enfield Lock station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Do you seal kitchen plinths to the floor?
Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone to keep mop water out.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can you reseal concrete floor joints in an industrial unit?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Let us know about the traffic when you ask for a quote.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
What affects the cost of floor joint sealing
You will get a clear quote before any work starts. It’s based on:
- The type of sealant required
- Access and height
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- Whether it has been sealed before
- The type of property
- What’s wrong with the joints now
- Any access issues, like height or stairs
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.

What else we do in Sewardstone
New homes and floors in Sewardstone
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 they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
Schools such as Prince of Wales Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic. Letting a property close to Enfield Lock station? Then gaps at skirtings and thresholds are worth sealing between tenancies. As a London address, Sewardstone can be tricky for parking: let us know about parking bays, permits or a driveway.

Can I do it myself?
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 doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
