- Grout cracking in a straight line across a floor
- Skirting that has pulled away from the floor
- Failed seals where bathroom floors meet baths and panels
Looking after it afterwards
So the new joints stay in good condition:
- Check the sealant is paintable before decorating
- Mark off resealed joints in warehouses
- Keep floor cleaning water to a minimum at the edges
- Check skirting joints after the heating season
Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.
A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner and the edges sound.
Floor joint sealing in Harpsden, done properly
Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is normally the better choice. If you’re dealing with tiled floors with no room to move and chipped and open joints in warehouse floors, we can put it right.
Older homes in small places like Harpsden often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Do you need floor joint sealing in Harpsden?
When a tiled floor has no movement joints, the grout takes the strain. You’ll see a crack running along the grout, showing where a movement joint was needed.
The most common problems we see are:
- Open joints around bathroom floor edges
- Grout used at the floor edge instead of sealant
- Tiled floors with no room to move
- Floor edges that trap water and grime
Managing a site like Trinity Church of England Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

New homes and floors in Harpsden
Across Oxfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
For buildings such as Church of St Margaret, floor and skirting joints in halls and kitchens wear like any others. Rented homes near Henley-On-Thames station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies.

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, then guaranteed for a year.
If you do try it yourself, take your time over the 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.
When something else is needed
To be straight with you, some problems need a different trade:
- A tiled floor that needs relaying
- Failed waterproofing under a wet room floor
- Floors that are uneven or need levelling

How the job changes by surface
Concrete floor joints
Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.
What happens on the day
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work generally takes a morning or an afternoon for most homes. For a village or hamlet like Harpsden, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- The joint is tooled neatly and the cure time explained.
Before we arrive

Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
My floor grout keeps cracking in a line. Can you help?
Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What happens if it’s left?
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges and keeps the damage down. In a small place like Harpsden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
