Floor joint sealing for homes and businesses in Farnham
Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors. We are often asked to deal with chipped and open joints in warehouse floors and dirt and water collecting in open floor joints, on wet room & bathroom floors, concrete floor joints and commercial floors.
Older homes in small places like Farnham often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Farnham: your questions answered
I let a flat near Stansted Mountfitchet station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Can you do floor joint sealing in Farnham?
Yes. We work across London and the South East, and Farnham is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can grout be replaced with sealant on a tiled floor?
Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What should I tell you?
A short description and the location, with photos by email if possible. If we need more, we will ask.
Do you seal floor joints in bathrooms and kitchens?
Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What we cannot put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Loose, hollow or cracked tiles, which need a tiler
- Bouncy or failing floorboards
- Large cracks that need a surveyor
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

What floor joint sealing looks like in Farnham
Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.
If you let a flat or house near Stansted Mountfitchet station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. For site and facilities teams at buildings such as Farnham Church of England Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

When to call us in Farnham
Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and behind skirting and plinths.
People usually contact us when they notice one of these:
- Grout cracking in a straight line across a floor
- Grout used at the floor edge instead of sealant
- Gaps opening between the floor and skirting
- Gaps between floors and kitchen plinths
Community buildings like Church of St Mary the Virgin are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Why it’s worth doing now in Farnham
Left open, concrete joints break down under traffic. A sealed joint supports the edges. Around Farnham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
