Floor joint sealing in Wealdstone
Across Wealdstone, we seal floor and skirting joints in homes and businesses. Each job starts with looking at the floor and the gap, since that decides which sealant suits. We work on commercial floors, wet room & bathroom floors and skirting boards, and the jobs we see most are failed joint filler in concrete floors and grout used at the floor edge instead of sealant.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
All of our work is guaranteed for twelve months.

Wealdstone: your questions answered
Is parking a problem for a job in Wealdstone?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you do floor joint sealing in Wealdstone?
Yes, Wealdstone is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.
How long before the joint can take traffic?
That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
How long will you be here?
Typically it takes a few hours for most rooms, longer for large commercial floors. Bigger jobs take longer, and we’ll say how long yours will take.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job.
What affects the cost of floor joint sealing
We quote each job individually. This is what makes a difference:
- When we can work, for business premises
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The product the joint needs
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before any work starts.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
- Whether it has been sealed before
- Roughly how big the job is
Getting a quote is simple: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Surface by surface
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.
Skirting boards
Gaps between skirting and floor open as timber and floors move. We seal them with a flexible sealant rather than caulk in a colour to suit.
When to call us in Wealdstone
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.
Look out for these signs:
- Worn sealant at door thresholds
- Rigid edge joints in tiled floors
- Tiled floors with no room to move
- Open joints that fill with dirt
For landlords with property near Harrow & Wealdstone station, a tidy floor and skirting joint helps a rental look ready for the next tenant.
What to look for in a quote
- Is VAT in the price?
- How much experience the applicator has
- What the cure time is
- Whether they seal over old material or remove it
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours, depending on the length of joint. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Wealdstone. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- We take out any old caulk, sealant or grout along the line.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- The sealant goes in, chosen for the floor and coloured to suit it.
- We tool the joint 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 about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Failed waterproofing under a wet room floor
- Subfloor problems that need a flooring contractor
- A tiled floor that needs relaying
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.

New homes and floors in Wealdstone
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.
Schools such as Marlborough Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. For buildings such as Holy Trinity Church, floor and skirting joints in halls and kitchens wear like any others.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check skirting joints after the heating season
- Get cracks along tile grout lines looked at early
- Mark off resealed joints in warehouses
- Don’t slide heavy items over sealed joints
Silicone sealant is not made to take paint. If you plan to paint, we will use a paintable product.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.
