New homes and floors in Queensbury
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. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
If you look after a building such as Glebe Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Rented homes near Kenton station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies.

Floor joint sealing for homes and businesses in Queensbury
Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant and stops dirt collecting. We work on commercial floors, tiled floors and wet room & bathroom floors, and the jobs we see most are open joints that fill with dirt and grout used at the floor edge instead of sealant.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

What sealant work can’t fix
We won’t take on work that will not last, so these are the limits:
- Large cracks that need a surveyor
- A tiled floor that needs relaying
- Damaged concrete that needs breaking out and repairing
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Thresholds
- Concrete floor joints
- Tiled floors
- Skirting boards
- Wet room & bathroom floors
- Commercial floors
For landlords and businesses
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
How we quote for floor joint sealing
The quote reflects the job in front of us. We look at:
- How many areas need sealing
- Working hours on commercial sites
- The type of sealant required
- The number and length of the joints
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What to tell us for a quote
When you call or email, it’s useful to know:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Should I try it myself first?
If you are set on DIY, put the effort into 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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
FAQs for Queensbury
Is parking a problem for a job in Queensbury?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
I let a flat near Kenton station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Why has a gap opened under my skirting?
Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Can grout be replaced with sealant on a tiled floor?
Often, yes. Straight cracks in grout often show where a movement joint was needed. We rake out that line and seal it with flexible sealant.
What does floor joint sealing cost?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us with a short description of the job.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
The process
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most rooms, longer for large commercial floors. In Queensbury, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- 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.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Related advice
What we’re called out for in Queensbury
Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water so the gap reappears.
People normally contact us when they notice something like this:
- Grout used at the floor edge instead of sealant
- Gaps opening between the floor and skirting
- Failed joint filler in concrete floors
- Failed seals where bathroom floors meet baths and panels
Queensbury is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Commercial floors

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.
