A cleaning service for all five villages of Dennis
Sentinel Cleaning Company cleans homes, cottages and vacation rentals throughout Dennis, MA, seven days a week. We are based in Hyannis, about fifteen minutes west, and have served the Mid-Cape since 2008. Dennis stretches from Cape Cod Bay to Nantucket Sound, and the two coasts produce very different houses and very different cleaning work.
Dennis villages we cover
Dennis Village
The historic center along Route 6A, near the Cape Playhouse and Scargo Lake. Older homes, many year-round owners, and a steady schedule of recurring cleaning.
East Dennis
Bayside homes near Sesuit Harbor and the Cape Cod Bay beaches. Larger second homes with big water-facing windows and seasonal use.
South Dennis
Mostly inland, residential and year-round, with family homes that book recurring and deep cleaning more than rental turnovers.
West Dennis
Near West Dennis Beach and the Bass River, with summer homes and rentals of every size, from small capes to large waterfront houses.
Dennis Port
Dense neighborhoods of beach cottages and small rentals close to the south shore. High turnover volume in July and August.

Cleaning problems we see most in Dennis
- Tidal flat sand on the bay side. The flats at low tide mean fine, wet sand and mud on feet, dogs and beach gear. It dries into a gritty film on floors and in entry rugs.
- Cottage bathrooms. Small, often poorly ventilated bathrooms in older cottages hold humidity and grow mildew at the caulk line. We scrub, dry and flag it early.
- Outdoor showers. Standard at Dennis Port and West Dennis rentals, and they collect sand, hair and soap scum all summer.
- Closed houses through the winter. Seasonal homes that are closed without a proper clean open musty in spring. A closing clean in October or November prevents it.
How the Dennis year runs
Summer in Dennis means cottage turnovers near the south shore beaches and opening cleans for bayside second homes. After Labor Day the work shifts to post-season deep cleans and closing cleans for cottages that stay empty until May. Year-round homes in Dennis Village and South Dennis book Thanksgiving and holiday cleaning in November and December, and January is a good month for a quiet deep clean.
If you are closing a Dennis cottage this fall, our guide to closing a Cape Cod vacation home and the fall cleaning checklist explain the order of work.

Frequently Asked Questions
Do you provide house cleaning in Dennis, MA?
Yes. Sentinel Cleaning Company cleans homes and rentals in all five villages of Dennis: Dennis Village, East Dennis, South Dennis, West Dennis and Dennis Port. We work seven days a week from 7am to 9pm.
Do you clean beach cottages in Dennis Port and West Dennis?
Yes. Cottages near the south side beaches are some of the most common rentals we turn over in Dennis. We work in grouped schedules so several cottages in the same area can be turned on the same day.
What makes bayside homes in Dennis harder to clean?
Homes on the Cape Cod Bay side near the tidal flats take in fine wet sand and mud on feet and gear, and their large water-facing windows collect salt film. We clear tracks and entries dry first and use a proper glass method on the seaward windows.
Can you clean my Dennis home while I am off Cape?
Yes. Many Dennis owners live off Cape. We coordinate access by key, lockbox or property manager and confirm when the work is done.
What do Dennis homeowners book in the fall and winter?
Post-season deep cleans, seasonal closing cleans for cottages that sit empty until spring, carpet and window cleaning, and Thanksgiving and holiday cleaning for year-round homes.
