“Found this wonderful company after searching the internet for a deep cleaning service. What a great find. Everything was arranged via email, all the jobs I wanted doing were logged and returned to me within hours. I booked a date and time and made payment by Bank Transfer the day before. A team of employees arrived on time and quickly got to work. They were friendly, professional and very thorough with the cleaning. They had brought their own products and cleaning equipment. On returning to the flat I was very impressed, the main bedroom was cleaned to high standards and ready to have the new bed due to be delivered on Friday. The bathroom was outstanding and cleaned superbly. I had to leave but feedback from my daughter was overall excellent for the rest of her flat. A grand job .”

“I was searching for an End of Tenancy clean and found the prices reasonable with Tenancycleaner.com. Good communication with Amy from the Amalia Team in arranging a time to complete the work.

What customers say about Cosmina
- ★★★★★TrustpilotPhenomenal Service & Beautiful Energy—I will never use anyone else! ⭐️⭐️⭐️⭐️⭐️
“I cannot recommend Cosmina and her team highly enough! They have done 5 to 6 deep cleans for me now, and I can say with absolute certainty that I will never use anyone else. They consistently go above and beyond. Their work ethic is absolutely unmatched—they are so hardworking, and every single time they visit, my home is left looking completely pristine and perfect. But what truly sets them apart is the energy they bring into your space. Cosmina and her team are so genuine, incredibly helpful, and exude such beautiful, good vibes. When they finish a clean, it’s not just that the space is physically spotless; the actual energetic vibe of my home feels amazing, clear, and totally uplifted. It is a joy to have such good people doing such incredible work. Thank you, Cosmina and team, for what you do. God bless you in abundance! ✨”

This is the first time I've booked a cleaning service and what a great experience. I'll definitely be using them again and happy to recommend them to friends and family. The whole process of booking the service, gentle reminders and right through to the completion of the job is so easy and amazing. Thank you!!”

Jennifer · July 2023
- ★★★★★TrustpilotRecommend (esp. Cosmina et. al.)
“Had Cosmina and her colleague/maybe mum? do our end of tenancy clean today of just the communal areas. Tbh was cheapest service we could find, as we’re students. We were a bit nervous because of some of the mixed (and some fake sounding lol) reviews here. It may be dependent on cleaner, but we found they did a really great job, it was efficient and thorough- exactly what we wanted. Also the customer service emails beforehand were pretty speedy too. So yeah our experience was all round positive.”
Emv · July 2023
- ★★★★★Google
“Accommodated me on a short notice on a weekend (literally within 4 hours). Cosmina and her team did a thorough job, especially with dirty oven, and left my newly moved in flat in a great condition. There were some minor things I discovered later but doesn’t take away from the proper job they did. I would definitely use them again.”

Tell us about the rooms
A deep clean is priced by the rooms and extras you choose. List every bedroom, bathroom and any extras such as the oven or carpets so the visit in Welwyn Garden City is booked for the right amount of time.
Inside a one-off deep clean in Welwyn Garden City

Spring cleaning in Welwyn Garden City and other good times to book
Some households book a spring clean as a yearly reset; others book before moving in, after building work, before selling or ahead of a family visit.
Homes in Welwyn Garden City and AL7

What does a deep clean in Welwyn Garden City cover?
Kitchens are degreased, including the hob and extractor, and cupboards are cleaned inside and out. Bathrooms and en-suites are descaled and disinfected. In every room the team cleans skirting boards, radiators, doors, switches and reachable internal windows, then vacuums and mops the floors. Oven and carpet cleaning can be added when you book.
How does a deep clean differ from a regular clean?
A regular clean keeps on top of surfaces week to week. A deep clean goes further, into grease, limescale, the insides of cupboards and dust along skirting boards and radiators. For handing back a rental, an end of tenancy clean is the better fit.
Do I have to be at home?
No. You can stay in or arrange access, for example by leaving a key, and check the result when you get back. Please keep pets out of the rooms being cleaned.
Can I include oven or carpet cleaning?
Yes. Select them as extras when booking and they are done on the same visit.
How much is a deep clean in Welwyn Garden City?
Deep cleaning in Welwyn Garden City starts from £180. Your price depends on the rooms and extras you pick and is shown in full before you book. Typical job £290 — based on 1,824 completed jobs in the last 12 months
Is equipment included?
Yes. The team arrives with its own products and equipment, and both are included in the price.
