It was my first time using #Hashtag Clean Ltd for end of tenancy, they did a fantastic job and I couldn't be any thankful, they went above and beyond since they had to clean not just clean the property but the furniture in the property. I would recommend using them again for future end of tenancy Thank you to the team.Posted on Emily PaulleyTrustindex verifies that the original source of the review is Google. Absolutely first class service and customer service from start to finish. Would recommend any tenant to use this business for their end of tenancy clean.Posted on Marcus GrimesTrustindex verifies that the original source of the review is Google. Outstanding!Posted on Theo RichardsTrustindex verifies that the original source of the review is Google. Hashtag Cleaning were booked at the recommendation of the letting agent of my previous tenancy and I couldn't echo their sentiments enough. Hashtag proactively arranged collection of keys to the property via the letting agency. No stone was left unturned during the clean and I was extremely happy with the results. Specific areas I'd listed to focus on prior to the clean were cleaned with ease and looked good-as-new. Upon review of property, I had my full security deposit monies returned to me. All dealings with their front-line and bookings teams were extremely pleasant - all of their help has been massively appreciated, thank you!
