About our floor joint sealing in Nettleden
We seal floor joints in homes, offices and commercial buildings across Nettleden. Each job starts with looking at the floor and the gap, since that decides which sealant suits. We work on concrete floor joints, tiled floors and commercial floors, and common reasons people get in touch are open gaps along the bottom of skirting boards and caulk that has cracked where the floor moves.
Around Nettleden, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We stand behind the work with a one-year guarantee.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
What sealant work cannot fix
Before booking, it’s worth knowing the limits too:
- Structural movement or subsidence
- Concrete repairs beyond the joint
- Tiles that have lifted or broken
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Avoid caulk in bathrooms and kitchens
- Check the sealant is paintable before decorating
- Have a cracking tiled floor checked before tiles break
- Check skirting joints after the heating season
Silicone sealant is not made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the surface smoother.
Floor joint sealing in Nettleden: local notes
Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
Letting a property close to Berkhamsted station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty. Community buildings like Church of St Lawrence are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. If you look after a building such as Great Gaddesden Church of England Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Different surfaces, different methods
Thresholds
Two different floors meeting at a threshold move differently. A flexible sealant bridges them.
Wet room and bathroom floors
Bathroom floor edges get wet at every clean. A flexible seal stops water running into the gap.
How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a morning or an afternoon for most homes. Somewhere as small as Nettleden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the gap and the floor type and agree the right sealant.
- We take out any old caulk, sealant or grout along the line.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
Why act early in Nettleden
Left open, concrete joints break down under traffic. A sealed joint supports the edges and keeps the damage down. Around Nettleden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas

Why does the gap under my skirting keep coming back?
Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you offer different sealant colours?
Usually, yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Should I try it myself first?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
