We are Grilled Grub based in Maidenhead and as you can imagine need a cleaning company to make sure our equipment is in the best condition possible. We have used J and L for our business to clean our extraction system twice now, the staff were really professional, the job done fantastic and we would personally like to thank Elizabeth and the staff involved in the cleaning process. We thoroughly recommend them as a business and will definitely use them in the future.

So great!! So happy I went with this company. Was in search for a deep deep clean for my bathroom, have had 2 industrial cleans now with other companies but looked this time for specific bathroom cleaners who can get rid of mould and dirty ventilators … look no further. I found them here !! Elisia and Claudia Were the cleaners who did my bathroom, they were speedy and fab ! Attached images for proof. Top images are before , and bottom now :)

Beata provided a professional service in promptly responding to my queries via email and was accommodating to availability in organizing the deep clean of kitchen. Alicia and Klaudia were very prompt and arrived 15mins before arrival time. They were very professional, arrived with own necessary equipment, wore protective footwear over their own shoes and were quick and efficient. They removed the heavily stained tile grouting, grill and oven of grease and removed the stickiness that covered the worktops. In addition, they were very respectful and polite. Overall, very happy and satisfied with the service they provided.
