Floor joint sealing in Upper Hartfield
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out. We work on skirting boards, tiled floors and commercial floors, and the jobs we see most are perimeter joints in tiled floors filled with grout and open gaps along the bottom of skirting boards.
Work in a small place like Upper Hartfield just needs the journey and access planning, and the work itself is the same as on any site.
Your job is guaranteed for a year, as with all our work.

Upper Hartfield: your questions answered
Is Upper Hartfield within the area you cover?
Yes, Upper Hartfield is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do floor joint sealing in Upper Hartfield?
Yes. Our work covers London and the South East, and Upper Hartfield is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can grout be replaced with sealant on a tiled floor?
Often, yes. A crack along a grout line often means the floor needs room to move. We replace that grout with a flexible joint.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
How do I get a quote for floor joint sealing in Upper Hartfield?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or email us with a short description of the job.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you seal kitchen plinths to the floor?
Yes. The old joint comes out and a flexible silicone replaces it.
What happens if it’s left?
Not every floor joint takes the same sealant: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. Older cottages and farmhouses around Upper Hartfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What affects the cost of floor joint sealing
We don’t publish a price list. The quote depends on:
- How easy the joints are to reach
- Mould in or behind the old joints
- The product the joint needs
- The number and length of the joints
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, and we will explain the quote if you ask.
What we need to know
To make quoting easier, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Access, such as stairs, a lift or height
- Roughly how big the job is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
How the job changes by surface
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.
Wet room and bathroom floors
Floor joints in bathrooms take water every day. They’re sealed with a flexible, anti-fungal silicone.
How it works
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take a morning or an afternoon for most homes. Somewhere like Upper Hartfield needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Tell us about any water getting in

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Across East Sussex, 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.
For landlords with property near Ashurst Kent station, gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as Holy Trinity Church, floor and skirting joints in halls and kitchens wear like any others.
