Floor joint sealing in Hartlip, done properly
Thresholds are where two floors, or a floor and a door, meet. We seal them with a flexible sealant suited to the floor finishes either side so the joint stays neat. Common call-outs are for rigid edge joints in tiled floors and open gaps along the bottom of skirting boards, across thresholds, tiled floors and commercial floors.
Around Hartlip, 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.
Your job is guaranteed for a year, as with all our work.

Common questions in Hartlip
Is Hartlip within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Hartlip in your area for floor joint sealing?
Yes. Our work covers London and the South East, and Hartlip is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Hartlip, along with the rest of our area.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
When can I walk on the floor?
That varies with the sealant and the room. We give you the times for walking, cleaning and traffic when we finish so there’s no guesswork.
How long does the job take?
As a guide, most jobs take a morning or an afternoon for most homes. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What affects the cost of floor joint sealing
The quote reflects the job in front of us. We look at:
- How easy the joints are to reach
- How much there is to do
- Any working-time requirements on site
- How many rooms, windows or areas are involved
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What to tell us for a quote

- If someone has resealed it before
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- How we’d reach the joints
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Cone off fresh joints until they’re ready
- Check skirting joints after the heating season
- Do not slide heavy items over sealed joints
- Sweep along the edges of the floor
Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.
In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.
Different surfaces, different methods
Tiled floors
Perimeter joints in tiled floors should be sealant, not grout. Grout at the edge is removed and replaced with sealant.
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. We bridge them with a flexible bead.
How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most rooms, longer for large commercial floors. Somewhere like Hartlip needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we check the joint and the floor and agree which sealant suits it.
- We take out any old caulk, sealant or grout along the line.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear the area around the work
- Tell us if parking is tricky

Advice
New homes and floors in Hartlip
Across Kent, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
Community buildings like Church of St Michael are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Managing a site like Hartlip Endowed Church of England Primary School? Then entrance and corridor floor joints take a lot of traffic.

The most common problems we see are:
- Open joints that fill with dirt
- Grout used at the floor edge instead of sealant
- Tiled floors with no room to move
- Gaps between floors and kitchen plinths
For landlords with property near Newington station, gaps at skirtings and thresholds are worth sealing between tenancies.
