What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the length of joint and we leave things clean and tidy. In a London area like Widmore, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Advice
About our floor joint sealing in Widmore
A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors. We are often asked to deal with open joints around bathroom floor edges and concrete floor joints that have broken down, across thresholds, commercial floors and concrete floor joints.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
Each job carries a 12-month guarantee, large or small.

Widmore: your questions answered
Is Widmore in your area for floor joint sealing?
Yes, Widmore is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can parking be tricky for a visit in Widmore?
Parking in Widmore, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you have insurance?
Yes. We are fully insured.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Why does the gap under my skirting keep coming back?
Movement from drying timber and settling floors opens the gap. Caulk tends to crack; a flexible sealant doesn’t.
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. Tell us what runs over the floor.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
How long before the joint can take traffic?
Follow the cure time we give you. Feet are usually fine first, then mopping, then heavy wheels, depending on the product.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Common problems we fix in Widmore
An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap.
People normally contact us after spotting something like this:
- Open joints that fill with dirt
- Open gaps along the bottom of skirting boards
- Caulk that has cracked where the floor moves
- Rigid edge joints in tiled floors
Community buildings like Church of St George are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.
Questions to ask before you book
- Who turns up on the day
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- What the cure time is
What else we do in Widmore
Why it’s worth doing now in Widmore
The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Using the wrong one is why many floor joints fail. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.

New homes and floors in Widmore
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. 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 is why the skirting and threshold joints need a flexible seal.
Managing a site like Bullers Wood School for Boys? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Widmore is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What the job involves on each surface
Wet room and bathroom floors
Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone.
Skirting boards
Skirting pulls away from the floor as floors shrink and settle. We seal them with a flexible sealant rather than caulk in a colour to suit.
