Westminster: your questions answered
Can parking be tricky for a visit in Westminster?
Parking in Westminster, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Westminster for floor joint sealing?
Yes, Westminster 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.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
My floor grout keeps cracking in a line. Can you help?
Often, yes. A crack along a grout line often means the floor needs room to move. We rake out that line and seal it with flexible sealant.
Will I be able to paint over the new joint?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone will not take paint, so it’s kept for wet areas and unpainted joints.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Can I do 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 we handle floor joint sealing in Westminster
Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we use a flexible sealant that moves with the floor. If you are dealing with caulk that has cracked where the floor moves and dirt and water collecting in open floor joints, we can help, whatever the surface.
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.
Our work is backed for twelve months.

Quotes for floor joint sealing in Westminster
There’s no set price list. What we look at:
- Working hours on commercial sites
- Any mould that needs treating
- The number and length of the joints
- The old material and how stubborn it is
The cost depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Helping us quote
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- Any access issues, like height or stairs
- The rough size of the job
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours for most rooms, longer for large commercial floors. For a job in Westminster, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor.
- We check the joints and explain the aftercare.
Before we arrive
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints

Advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Other services in Westminster
When to call us in Westminster
Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and can reach the subfloor.
The most common problems we see are:
- Cracked grout where a tiled floor needs a movement joint
- Threshold joints that have opened or worn
- Skirting caulk that keeps splitting
- Grout used at the floor edge instead of sealant
For landlords with property near London Victoria station, gaps at skirtings and thresholds are worth sealing between tenancies.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Get cracks along tile grout lines looked at early
- Look at floor joints each spring
- Keep floor cleaning water to a minimum at the edges
- Do not paint over silicone
Avoid flooding the floor when you clean. Keeping the edges drier helps the sealant last longer.
A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.
Floor joint sealing in Westminster: local notes
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. The joint at the skirting or threshold has to allow for that. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
Managing a site like Harris Westminster Sixth Form? Then entrance and corridor floor joints take a lot of traffic. Community buildings like Christ Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.
