Some homes need more than a regular clean. If you need deep cleaning in Boulder, 303 Crown Maids covers everything that standard cleaning doesn’t. Whether it’s been a while since your last professional cleaning, you’re moving in or preparing for guests, or you just want a full reset, we handle the detail work most people skip.
We go inside appliances, behind furniture, into grout lines, and across every surface that builds up over time. The result is a home that feels completely different, and a much easier baseline to maintain going forward.
We serve Boulder, Lafayette, Longmont, Louisville, Erie, Superior, Gunbarrel, Brighton, Denver, Fort Collins, and communities across the Front Range.
What’s Included in a Deep Cleaning
Every deep clean follows our 75-point professional cleaning checklist, which includes everything in a standard clean plus the detail work most people skip or don’t have time for:
Kitchen Everything from a standard clean, plus: inside the oven, inside the refrigerator, inside cabinets and drawers, inside the dishwasher (including door seals and filter), inside the pantry (all shelves and corners), sanitizing the trash can, and cleaning the range hood thoroughly.
Bathrooms Everything from a standard clean, plus: scrubbing tile grout, cleaning inside the linen closet and shelves, detailing faucet aerators and the showerhead, removing and cleaning drain stoppers, wiping down doors and door frames, and cleaning inside drawers and cabinets.
Bedrooms and Living Spaces Everything from a standard clean, plus: wiping down all baseboards, cleaning window frames, vacuuming under furniture and under beds, dusting crown molding and chair rails, cleaning inside linen closets (shelves, rods, floors), cleaning inside all drawers, cleaning the tops of door frames, and documenting any existing damage.

When You Need a Deep Cleaning
Not every visit needs to be a deep clean. But there are specific times when a standard cleaning just isn’t enough:
First-time clients. We always recommend starting with a deep cleaning as your first appointment in Boulder. It brings your home to a high baseline so that future standard cleanings can maintain it efficiently. Skipping the deep clean first means your standard visits are playing catch-up instead of maintaining.
Homes that haven’t been cleaned professionally in a while. If it’s been a few months (or longer), buildup in places like grout lines, oven interiors, behind appliances, and inside cabinets needs targeted attention that a standard clean doesn’t cover.
Seasonal resets. Spring and fall are popular times for deep cleaning Boulder homes along the Front Range. Colorado’s dry climate means dust accumulates quickly, and hard water deposits build up on fixtures and glass faster than in more humid states. A seasonal deep clean keeps those issues from compounding. According to the American Cleaning Institute, regular deep cleaning significantly reduces allergens and improves indoor air quality.
Before or after hosting. Holiday gatherings, CU graduation weekend, or any time you want your home to look and feel its best.
Post-renovation. Construction dust gets everywhere, including places you can’t see. A deep clean after a remodel makes sure everything is actually clean, not just surface-level tidy.
Before listing your home. A deep clean before photos and showings makes a noticeable difference in how buyers perceive the space.

Deep Clean First, Then Maintain with Standard Service
Here’s the approach that works best for most of our clients: book a deep cleaning as your first visit. Once that baseline is set, transition to a recurring standard cleaning on a weekly, biweekly, or monthly schedule. You’ll save money per visit with our recurring discounts (5% monthly, 10% biweekly, 15% weekly), and your home stays at the level the deep clean established.
This is how you stop the cycle of things building up and then needing another intensive reset every few months.

Frequently Asked Questions About Deep Cleaning
What’s the difference between a deep clean and a standard clean? A standard clean covers everyday surfaces, floors, kitchens, and bathrooms. A deep clean adds inside appliances, grout scrubbing, baseboards, inside cabinets and drawers, behind furniture, window tracks, light fixtures, and more. Full comparison on our checklist page.
How long does a deep cleaning take? It depends on home size and condition. Most deep cleanings for a 2-3 bedroom home take between 3 and 5 hours. Homes that haven’t been cleaned in a while may take longer.
How much does deep cleaning in Boulder typically cost? Pricing varies by home size, number of rooms, and condition. Deep cleans cost more than standard visits because of the additional time and detail work involved. See your exact price instantly here.
