Meet the team behind the clean
From Our Home to Your Front Door
Nautilus Group Cleaning Services is owned and operated by David and WendiSue Nash — a husband-and-wife team who built their reputation cleaning businesses, homes, and commercial facilities in Texas before relocating to Helena to be closer to family and community. They arrived with nothing but a work ethic, an RV, and a commitment to do things right. Within months they had earned their permits, insurance, bonding, and an independent contractor's license — and a growing list of homeowners, property managers, and businesses who trusted them.
As proud members of the Helena Area Chamber of Commerce, David and WendiSue are invested in this community. When you hire Nautilus Group, you're hiring people who show up, do the work, and stand behind it.
On our way to your place!

What Our Clients Are Saying
Absolutely love David & WendiSue! They are fast & efficient. They are happy to work around us if we are home, they are also animal lovers and don't mind my fur babies pestering them while they clean. They provide all their own equipment & supplies and always leave my house sparkling. Very reliable and affordable. Can't say enough great things about them!
Found out I had issues with mold in my rv causing health issues. Nautilus group came to me and cleaned every bit of mold issues I had. My health issues started getting better after they were through. It was comforting to know that they are insured and bonded. They are a trustworthy team. I appreciate everything they did. I would definitely recommend them for anything!
