The cleaning service was swift and spotless. Our landlord was very pleased with the conditions. Booking was easy and service was customised. J&I offered a site visit/video viewing to give a reasonable quote.

Found J&I through a Google search. They were very responsive to my questions and easy to book with. The cleaner they sent did an amazing job on the bathroom deep clean, even managed to remove stains I thought were permanent. She was very professional and extremely polite. Brought all their own supplies and even a step ladder to reach the ceiling. I would totally recommend J&I for deep cleaning.

They did a fantastic job for end of tenancy clean. The inspector was impressed and, so far, not had an extra charges from the letting agency. They arrived bang on time and the communication with the office (i had to change the original booking) was excellent. The price was very competitive compared to online search results. Would especially recommend if you live in Quintain flat.

I had a deep clean done on Friday and OMG! What a wonderful experience. She did such a marvellous job. She literally cleaned from head to toe including inside my bathroom cabinet and sink vanity drawers. I would absolutely use this company again and am absolutely happy to recommend to others.

J&I Cleaning were recommended to us by a friend, work from a High Street office, gave me a reasonable quote over the 'phone. They require full payment in advance (!) but... recommended and office based, so... Their worker turned up promptly, got on with the work, moved furniture carefully and appropriately put it back and did a very good job, all within less time than had been predicted. We think money will spent

The cleaners did an excellent job on my kitchen. I had alot of things and so they ran out of time, but I recommend them to others, for they work so well and to a very high standard. I especially love the cooker and microwaves. I would use them again.
