Floor & skirting joints in Barnes Cray, Kent
Problem with your floor joints in Barnes Cray? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Gaps between floors and kitchen plinths
- Floor edges that trap water and grime
- Cracked grout where a tiled floor needs a movement joint
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Sweep along the edges of the floor
- Keep caulk for dry, still joints only
- Look at floor joints each spring
- Avoid sloshing water against skirting
Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.
How we handle floor joint sealing in Barnes Cray
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We are often asked to deal with gaps between floors and kitchen plinths and open gaps along the bottom of skirting boards, across wet room & bathroom floors, concrete floor joints and skirting boards.
For a new home in or near Barnes Cray, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
All of our work is guaranteed for twelve months.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Barnes Cray questions
Is Barnes Cray within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Slade Green station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
How long does floor joint sealing take?
A typical job takes a few hours for most rooms, longer for large commercial floors, including preparation and clearing up. We’ll confirm how long when we quote.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Where is Mr Mastic based?
We work from Crawley. We cover Barnes Cray and the rest of Kent.
Are you insured?
Yes. We’re fully insured.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

What else we do in Barnes Cray
Joints and finishes in Barnes Cray homes
Across Kent, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
For site and facilities teams at buildings such as Haberdashers' Aske's Crayford Academy, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Rented homes near Slade Green station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a church, hall or community building such as Christ Church, joints in its floors, skirtings and thresholds need resealing as they wear.

Why it’s worth doing now in Barnes Cray
The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Using the wrong one is why many floor joints fail. Homes in smaller places like Barnes Cray can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Different surfaces, different methods
Wet room and bathroom floors
Mop water gets into any open joint at the edge of a bathroom floor. A flexible seal stops water running into the gap.
Concrete floor joints
We clean concrete joints out thoroughly before sealing first. Backing goes in where the depth needs controlling.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on the length of joint, and the area is left clean. For a job in Barnes Cray, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied.
- We check the joints and explain the aftercare.
Preparing for the visit
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
