What the job involves on each surface
Skirting boards
Skirting pulls away from the floor as floors shrink and settle. We seal them with a flexible sealant rather than caulk.
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. We rake out any grout there and reseal.
How we handle floor joint sealing in Clapham Park
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant so water and dirt can’t get in. Typical jobs include gaps between floors and kitchen plinths and chipped and open joints in warehouse floors, across wet room & bathroom floors, thresholds and commercial floors.
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 Clapham Park and beyond.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What we are called out for in Clapham Park
Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting and they change again in summer.
Common reasons people contact us include:
- Failed joint filler in concrete floors
- Cracked caulk along skirting in bathrooms and kitchens
- Floor edges that trap water and grime
- Threshold joints that have opened or worn
For buildings such as Church of the Holy Spirit, floor and skirting joints in halls and kitchens wear like any others.

What affects the quote in Clapham Park
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- How many areas need sealing
- The type of sealant required
- The old material and how stubborn it is
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
Before you ask for a quote, have a think about:

Your questions about floor joint sealing in Clapham Park
Is Clapham Park in your area for floor joint sealing?
Yes, Clapham Park is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Is parking a problem for a job in Clapham Park?
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.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Are you insured?
Yes, we are fully insured for every job we do.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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 fails, we can still redo it.
When something else is needed
It helps to know what we cannot do too:
- Floors that are uneven or need levelling
- Leaks from a failed tanking system
- A tiled floor that needs relaying
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a morning or an afternoon for most homes and we leave things clean and tidy. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Old caulk, grout or sealant is removed from the joint.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

What happens if it’s left?
Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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 Clapham Park.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

What floor joint sealing looks like in Clapham Park
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 each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
If you let a flat or house near Clapham High Street station, a tidy floor and skirting joint helps a rental look ready for the next tenant. For site and facilities teams at buildings such as Glenbrook Primary School, entrance and corridor floor joints take a lot of traffic.
