Floor joint sealing in Petts Wood, done properly
Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed. We work on thresholds, skirting boards and tiled floors, and common reasons people get in touch are gaps opening between the floor and skirting and dirt and water collecting in open floor joints.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why act early in Petts Wood
Floor joints left open collect dirt that is hard to clean out, and they look untidy. Sealed joints are easier to keep clean and look tidier. 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. Putting it right early is much less trouble.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

When to call us in Petts Wood
Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open.
Signs it’s time to call us include:
- Gaps at thresholds between rooms
- Failed seals where bathroom floors meet baths and panels
- Floor edges that trap water and grime
- Cracked caulk along skirting in bathrooms and kitchens
Petts Wood is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What to look for in a quote
- When the joint can take water or movement
- What product goes in the joint
- Is the old sealant removed completely?
- The length of the guarantee
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Structural movement or subsidence
- Cracked or broken concrete slabs
- Loose, hollow or cracked tiles, which need a tiler
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Floor joint sealing in Petts Wood: local notes
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. The joint at the skirting or threshold has to allow for that.
For buildings such as St Francis Church, joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like Crofton Junior School? Then entrance and corridor floor joints take a lot of traffic.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid caulk in bathrooms and kitchens
- Use a well-wrung mop rather than flooding the floor
- Check skirting joints after the heating season
- Ask before painting over a sealed joint
Silicone sealant isn’t made to take paint. If you plan to paint, we’ll 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.
Petts Wood: your questions answered
Can you help a landlord with a rental near Petts Wood station?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can parking be tricky for a visit in Petts Wood?
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.
Why has a gap opened under my skirting?
Floors shrink and settle, especially in the first year or two and through the heating season opens the gap. Caulk tends to crack; a flexible sealant does not.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
How long does the job take?
As a guide, most jobs take a few hours for most rooms, longer for large commercial floors. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can you use decorators’ caulk instead?
Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What the job involves on each surface
Skirting boards
If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.
Concrete floor joints
We clean concrete joints out thoroughly before sealing, vacuuming them clean. Backing goes in where the depth needs controlling.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours, depending on the length of joint. In Petts Wood, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we check the joint and the floor and agree which sealant suits it.
- We take out any old caulk, sealant or grout along the line.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Before we arrive
- Mention any tricky access
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
