- Failed joint filler in concrete floors

- Gaps at thresholds between rooms
Leave it or put it right?
Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant stretches instead, so the joint stays closed. Around New Denham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Floor joint sealing in New Denham
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. We’re often asked to deal with gaps opening between the floor and skirting and skirting caulk that keeps splitting, across thresholds, concrete floor joints and wet room & bathroom floors.
In a village or hamlet like New Denham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of floor joint sealing
Every job gets its own quote. These are the things that affect it:
- When we can work, for business premises
- Which sealant suits the joint
- How many areas need sealing
- Access and height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Roughly how big the job is
- Any access issues, like height or stairs
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.
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 new sealant bonds.
Wet room and bathroom floors
Floor joints in bathrooms take water every day. They’re sealed with a flexible, anti-fungal silicone.
How the visit works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a morning or an afternoon for most homes in most cases. Somewhere as small as New Denham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Let us know about parking restrictions
How to get a quote
We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or send us an email and describe the job, and photos are welcome.

Across Buckinghamshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.
If you look after a church, hall or community building such as St Francis, joints in its floors, skirtings and thresholds need resealing as they wear. Letting a property close to Denham station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Do you seal kitchen plinths to the floor?
Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone to keep mop water out.
Can you reseal concrete floor joints in an industrial unit?
Yes, from warehouses and units to offices and shops. We can plan around your opening times, and out-of-hours work can be arranged.
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.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Do you need floor joint sealing in New Denham?
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits so the gap reappears.
People usually contact us after spotting one of these:
- Concrete floor joints that have broken down
- Gaps between floors and kitchen plinths
- Perimeter joints in tiled floors filled with grout
- Threshold joints that have opened or worn
For site and facilities teams at buildings such as Hermitage Primary School, entrance and corridor floor joints take a lot of traffic.
Questions to ask before you book
- How long to leave it before use
- Which colour the sealant will be
- Whether VAT is included
- What preparation is included
What we can’t put right
It helps to know what we cannot do too:
- Concrete repairs beyond the joint
- A tiled floor that needs relaying
- Large cracks that need a surveyor
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
