How the job changes by surface
Concrete floor joints
Hard wheels break down the edges of open joints. A sealed joint protects the edges and stops debris collecting.
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. That line is converted to a flexible joint.
About our floor joint sealing in Wilstone
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant so water and dirt can’t get in. We are often asked to deal with failed joint filler in concrete floors and tiled floors with no room to move, across tiled floors, wet room & bathroom floors and concrete floor joints.
In a village or hamlet like Wilstone, 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.
Each job carries a 12-month guarantee.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep floor cleaning water to a minimum at the edges
- Mark off resealed joints in warehouses
- Have a cracking tiled floor checked before tiles break
- Vacuum floor joints regularly to stop grit building up
Silicone sealant isn’t 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. Resealing early keeps it out.
Your questions about floor joint sealing in Wilstone
Do you cover Wilstone for floor joint sealing?
Yes. Our work covers London and the South East, and Wilstone is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Is Wilstone within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Wilstone.
How long does the job take?
As a guide, most jobs take a few hours for most rooms, longer for large commercial floors. Larger jobs naturally take longer, and we will say how long yours will take.
What does floor joint sealing cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why it’s worth doing now in Wilstone
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job. Where a wall is exposed, as many are in small places like Wilstone, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

New homes and floors in Wilstone
Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
If you let a flat or house near Cheddington station, gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as St Cross, floor and skirting joints in halls and kitchens wear like any others. Schools such as Marsworth Church of England Infant School are buildings too, and entrance and corridor floor joints take a lot of traffic.
