Floor joint sealing in Denholm, done properly
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 work on wet room & bathroom floors, tiled floors and thresholds, and the jobs we see most are gaps between floors and kitchen plinths and cracked grout where a tiled floor needs a movement joint.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
There’s a 12-month guarantee on every job.

What floor joint sealing looks like in Denholm
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. Across the Scottish Borders, 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.
Community buildings like Minto Parish Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. If you look after a building such as Craigmount School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
Denholm is about 5 miles north-east of Hawick, in the Scottish Borders. Across the TD9 area, our applicators can take on floor joint sealing. Our the Scottish Borders coverage runs to 89 places, Denholm among them. Edinburgh is on our list too, around 39 miles away.

What happens if it’s left?
Left open, concrete joints break down under traffic. Resealing it early protects the edges before they need a bigger repair. In a place like Denholm, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours, depending on the length of joint, depending on the amount of work. Outdoor work around Denholm depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- We clean and dry the edges of the joint.
- We apply a flexible sealant suited to the floor and smooth it.
- We check the joints and explain the aftercare.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can

Your questions about floor joint sealing in Denholm
What guarantee comes with floor joint sealing in Denholm?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you do floor joint sealing in Denholm?
Yes, Denholm is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Avoid sloshing water against skirting
- Do not slide heavy items over sealed joints
- Keep heavy wheels off new concrete joints until cured
- Sweep along the edges of the floor
Silicone sealant is not made to take paint. If you plan to paint, we’ll use a paintable product.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the cost of floor joint sealing
Jobs vary more than people expect. What affects the quote:
- The number of rooms or windows
- The size of the job
- Whether there’s mould to deal with
- How easy the joints are to reach
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job

What the job involves on each surface
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. We reseal them with a floor-joint product suited to the traffic.
