What floor joint sealing looks like in Wallingford
Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.
For landlords with property near Cholsey station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. For buildings such as St Mary-le-More, floor and skirting joints in halls and kitchens wear like any others.

Floor joint sealing for homes and businesses in Wallingford
Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, then clean, back and seal the joint. We work on tiled floors, skirting boards and concrete floor joints, and people most often call us about failed joint filler in concrete floors and grout cracking in a straight line across a floor.
For a new home in or near Wallingford, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

Different surfaces, different methods
Skirting boards
Skirting gaps are one of the most common floor joints we seal. The old caulk is removed first so the bead sits on a clean surface.
Thresholds
Thresholds take daily traffic, so the sealant has to be tough as well as flexible and neatly finished.
Landlord and commercial work in Wallingford
Letting agents and landlords in Wallingford can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

What affects the quote in Wallingford
Your quote is based on your job. We look at:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Any working-time requirements on site
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Asking for a quote
When you call or email, it’s useful to know:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Any previous sealing or DIY work
- What’s wrong with the joints now
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
Leave it or put it right?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In an older home around Wallingford, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Signs you need floor joint sealing in Wallingford
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening between the floor and skirting
- Open joints that fill with dirt
- Cracked caulk along skirting in bathrooms and kitchens
- Concrete floor joints that have broken down
For site and facilities teams at buildings such as Fir Tree Junior School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It generally takes a few hours for most rooms, longer for large commercial floors. A visit to Wallingford is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and smooth it.
- Finally, we check the work and talk you through aftercare.
How to prepare
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

Is it worth trying it myself?

Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

We give you a cure time for each joint. Light use comes first, cleaning and heavy traffic later.
