Floor joint sealing in Neasden, 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. We’re often asked to deal with tiled floors with no room to move and rigid edge joints in tiled floors, across concrete floor joints, 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.
All our work is covered by our 12-month guarantee, wherever you are in Greater London.

Joints and finishes in Neasden homes
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
If you let a flat or house near Brent Cross West station, gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a building such as Northview Junior and Infant School, entrance and corridor floor joints take a lot of traffic.

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on the length of joint for a typical job. In Neasden, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Advice
Different surfaces, different methods
Skirting boards
Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking.
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it where it suits the floor.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Do you need floor joint sealing in Neasden?
Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting.
Signs it’s time to call us include:
- Skirting that has pulled away from the floor
- Threshold joints that have opened or worn
- Grout cracking in a straight line across a floor
- Cracked caulk along skirting in bathrooms and kitchens
As a London address, Neasden can be tricky for parking: let us know about parking bays, permits or a driveway.

Why it’s worth doing now in Neasden
Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. 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 Neasden.
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. The price is agreed before we begin.

Your questions about floor joint sealing in Neasden
Do you work for landlords with property near Brent Cross West station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can parking be tricky for a visit in Neasden?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do you work on commercial floors?
Yes, including warehouses, units, shops and offices. Work can be planned around your hours with out-of-hours work where needed.
Do you use a paintable sealant?
If you tell us beforehand, yes. Joints that will be painted get a paintable product, and silicone elsewhere.
My floor grout keeps cracking in a line. Can you help?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant, giving the floor room to move.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
How long does floor joint sealing take?
That depends on how much there is to do, but most jobs take a morning or an afternoon for most homes. We’ll tell you when we quote.
How we quote for floor joint sealing
The price is agreed before any work begins. It’s based on:
- When we can work, for business premises
- The number and length of the joints
- Whether there’s mould to deal with
- Access and height
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What to tell us for a quote
To make quoting easier, let us know:
- Photos by email, if that’s easy
- The address or postcode of the job
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
