Built from Scratch, Right Here in Helena
Nautilus Group Cleaning Services is owned and operated by David and WendiSue Nash — a husband-and-wife team who built their reputation cleaning hotels, homes, and commercial facilities in Texas before relocating to Helena to be closer to family. They arrived ready to start from scratch — and did exactly that.
Between them, David and WendiSue bring more than 25 years of hands-on cleaning experience. When you hire Nautilus Group, you get both of them — not one person on Monday and a different one on Thursday. Same two people, every single visit.
On our way to your place!

Frequently Asked Questions
Standard cleaning covers the recurring work that keeps a maintained home tidy — dusting surfaces, vacuuming, mopping floors, wiping down counters and appliances, scrubbing bathrooms, and taking out trash. A deep cleaning goes further: we get into the grout, clean inside the oven and refrigerator, scrub baseboards, wipe down light fixtures and switch plates, and address buildup in areas that don't get touched during a regular visit. If you haven't had a professional cleaning in a while, or you're starting a recurring service with us, a deep clean is the right place to begin.
Move-in and move-out cleaning is our most thorough residential service. We clean inside all cabinets and drawers, scrub the oven and refrigerator inside and out, clean all windows and window sills, wipe down baseboards and doors, disinfect bathrooms top to bottom, and leave every corner of the space ready for the next occupant. It's designed for renters, buyers, sellers, and landlords who need a space to pass inspection — or just not feel embarrassed handing over the keys.
Yes. We use eco-friendly cleaning products that we supply ourselves, so you don't need to worry about what we're bringing into your home. If you have specific sensitivities or preferences — a dog who's prone to licking everything, a toddler who treats the floor as a buffet — let us know when you request a quote and we'll work around it.
That's entirely up to you. Most of our regular clients give us access and go about their day. Some prefer to be home the first visit, which is completely understandable — you're trusting us with your space, and we think it's reasonable to want to see how we work before handing over a key. We're insured, bonded, and licensed, so however you're most comfortable is how we'll handle it.
Pricing depends on the size of your home, the type of service (standard, deep, or move-out), and how often you'd like us to come. Rather than quote a number that doesn't fit your situation, we'd rather talk it through with you. Call us at (817) 694-4003 or use the form on this page and we'll put together an accurate quote — no guesswork, no surprises.
It depends on your household. Busy families with kids and pets tend to benefit from weekly or bi-weekly visits. Smaller households or those who keep up with things themselves often find monthly works fine. If you're not sure, start with a deep clean and we'll give you an honest recommendation based on what we see — not what generates the most visits.
Yes, we bring everything — eco-friendly cleaning products, equipment, and supplies. You don't need to have anything on hand. If there's a product you'd like us to use (or avoid) for any reason, just let us know ahead of time.
Yes. Post-construction cleanup is one of our commercial services, and we handle it for both residential renovations and commercial build-outs. Construction leaves behind fine dust, debris, adhesive residue, and general chaos that standard cleaning products and a light touch won't fix. We go in equipped to handle it. Reach out through the contact form or call us directly to describe the project and we'll give you a quote.
