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! ✨”

“INCREDIBLE. No other words. form the process of being quoted, confirmed and the job. Cosmina was on time, super communicative and I was blown away by the detail. My outdoor deck looked like a different place. I hired a deep cleaning for a new home and I will be working with them again. HIGHLY RECOMMEND”

One-off Deep Cleaning in Welwyn: local guide
Welwyn deep cleans in numbers
Our 6 deep cleans in Welwyn have all been in AL6. Each was booked as a standalone deep clean, with the full price shown before confirming.
Clear the surfaces first
Put away clutter and valuables before the team arrives so they can spend the time on grease, limescale and dust rather than tidying.
What house deep cleaning in Welwyn involves
The team degreases the oven, hob and extractor, descales taps, tiles and shower screens, and cleans cupboards, skirting boards, radiators, doors and reachable internal windows before vacuuming and mopping. It is a one-off clean with no contract.
Spring cleaning in Welwyn 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 and AL6
Homes include period cottages in the old village, interwar and post-war family homes around Oaklands and Digswell, and larger detached houses on the outskirts. Lanes in the old village are narrow with limited parking, so let us know where our cleaners can park or if there is a driveway. Mention parking and any rooms to skip when you book deep cleaning in AL6.

What does a deep clean in Welwyn 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?
Deep cleaning in Welwyn 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 1,716 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.
