Floor & skirting joints in Long Crendon, Buckinghamshire
Our applicators work in Long Crendon on sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Gaps opening between the floor and skirting
- Threshold joints that have opened or worn
- Dirt and water collecting in open floor joints
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Use a well-wrung mop rather than flooding the floor
- Cone off fresh joints until they’re ready
- Use furniture pads near skirting
- Act on grout cracks that run in a straight line
Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant especially in the first few days.
A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.
About our floor joint sealing in Long Crendon
Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we use a flexible sealant that moves with the floor. Typical jobs include concrete floor joints that have broken down and open joints around bathroom floor edges, on wet room & bathroom floors, concrete floor joints and skirting boards.
In smaller places like Long Crendon, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Long Crendon questions
Can you help a landlord with a rental near Haddenham & Thame Parkway station?
Yes. We work for landlords and agents as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can you do floor joint sealing in Long Crendon?
Yes. We work across London and the South East, and Long Crendon is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
When can I walk on the floor?
Follow the cure time we give you. Light use comes first, cleaning and heavy traffic later, depending on the product.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can sealant along the skirting be painted?
On joints you want to paint, yes. Silicone in bathrooms and kitchens cannot be painted.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you use decorators’ caulk instead?
Not where the floor moves or gets wet. It splits once the floor shifts, so the gap comes back. A flexible sealant is the better choice.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
New homes and floors in Long Crendon
Floors around Buckinghamshire 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.
Community buildings like Church of St Mary are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. If you let a flat or house near Haddenham & Thame Parkway station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Signs you need floor joint sealing in Long Crendon
An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap and can reach the subfloor.
People usually contact us after spotting one of these:
- Failed joint filler in concrete floors
- Grout cracking in a straight line across a floor
- Worn sealant at door thresholds
- Caulk that has cracked where the floor moves
For site and facilities teams at buildings such as Long Crendon School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What happens if it’s left?
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. In an older home around Long Crendon, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
