I don't usually do these kind of reviews - but I want to thank Jonni publicly for a first class service in rectifying a small area of our wooden floor which seemed not to have had the full cleaning first time round. He assured me he would sort the issue next time he was in the area and true to his word I got a text within a few weeks to say he'd sort it the following week. I was seriously impressed - so often small things like this get promised to fix and it never happens! I'm happy to highly recommend him - excellent workmanship and super service.Posted on Google![]()

I contacted Jonni to get a quote to sand and re varnish our hall floor. He sent the quote very promptly and so I made an appointment for the work. Jonni arrived spot on the time he said. He has a lovely polite, quiet manner and got straight to work. Work finished to a very high standard - we couldn’t be happier. Jonni is very easy to have in the house. I couldn’t recommend him highly enough. Also very good value for moneyPosted on Facebook![]()

Watch how we clean, restore and polish natural stone, tile and grout.
Cleaning is only half of it. Where a floor has lost its finish, been scratched, etched or worn flat, I can grind, hone and polish the surface back, then seal it so it stays that way.
Do your marble, travertine, limestone or slate floors still gleam as they once did, or have they gone dull and lifeless? Over time natural stone becomes ingrained with dust, dirt, oily and waxy deposits and layers of old polish, and foot traffic slowly wears the surface flat.
Cleaning alone will not bring that back. Using diamond tooling, I grind out scratches and etching, hone the surface flat, then diamond polish it to the finish you want, whether that is matt, satin or a full high polish. It is a genuine restoration, at a fraction of the cost of lifting the floor and starting again.

Mopping moves dirt around. It settles into grout lines and into the texture of the tile, and no amount of household product will lift it back out. I use a weighted rotary machine and professional, pH-appropriate solutions to agitate the surface and release that soil from the pores of the tile and the grout.
It is then flushed and extracted under vacuum. That is a controlled rinse, not a high-pressure hosing. No mess, no water running under your kickboards, and your floor is walkable again the same day. Around 90% of grout has never been sealed, which is why it darkens so quickly. Once it is clean, I can seal it so it stays that way.
Luxury vinyl tile is sold as low maintenance, so most people assume a tired LVT floor is simply worn out. Usually it is not. What you are looking at is years of supermarket floor polish, mop residue and dressing that has yellowed, gone patchy and trapped dirt in the embossing.
I strip that build-up back to the original surface, deep clean the embossed texture, then re-dress the floor with a professional finish in the sheen you prefer, from matt through to high gloss. Karndean, Amtico, LVT, sheet vinyl and safety flooring all handled to manufacturer-safe methods.
Every floor is different, so nothing is guessed. I survey it, test it, and show you the result on your own floor before you commit to anything.
I identify the surface, test the finish, and clean a small area so you can see exactly what is achievable before you spend a penny.
Skirtings, kickboards and adjoining surfaces are masked and protected, and the floor is cleared and dry-soil removed.
Weighted rotary agitation with the correct solution for the surface, then a controlled rinse and vacuum extraction.
Where needed, diamond grinding and polishing to remove scratching and etching and bring the stone back to your chosen sheen.
An impregnating sealer or dressing is applied to repel spills and keep grout lines cleaner for longer, plus simple aftercare advice.
Specialist training, professional equipment and industry-standard materials, on every job and every floor type.
Marble, travertine, limestone, slate, granite and terrazzo, each treated with the correct pH-balanced method.
Scratches, etching and worn traffic lanes ground out and polished back, not just cleaned over.
Old polish stripped back, embossing deep cleaned, and the floor re-dressed in your chosen sheen.
Professional-grade impregnating sealers and dressings that repel spills and make maintenance far easier.
A survey and a test clean on your own floor, so you see the result first-hand before committing.
Save thousands by restoring the floor you already have instead of ripping it out and starting again.
The price quoted includes all labour, materials and equipment. No nasty surprises, no hidden extras.
Your 100% satisfaction is an absolute must for us. If you are not happy, we will re-clean it free of charge.
