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. Our Boulder deep house cleaning goes inside appliances, under 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.
Every residential deep cleaning we do follows the same documented 75-point cleaning checklist we use across every service line, so you can see exactly what’s covered before you book.
We serve the cities of Boulder, Longmont, Fort Collins, Lafayette, Louisville, Erie, Evergreen, Broomfield, Superior, Gunbarrel, Brighton, Denver, Loveland, Greeley, Windsor, and surrounding Front Range communities.
What’s Included in a Deep Cleaning
A professional deep cleaning covers everything in a standard clean plus the detail work standard visits skip entirely: inside appliances, grout lines, baseboards, window frames, and the buildup that collects over months in places most people never look. That’s the practical difference between a house deep clean and routine maintenance.
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.
The scope matters because buildup doesn’t happen evenly. For example, grease accumulates inside an oven over dozens of uses, and dust settles into baseboard corners and window tracks long before it’s visible. A standard clean keeps surfaces looking good between visits. A deep clean addresses what’s underneath those surfaces, which is what actually affects air quality, appliance performance, and how the home feels to people who spend time in it.
For the full side-by-side comparison of standard vs. deep vs. move-in/move-out cleaning, visit our cleaning checklist page.
Here’s what that looks like room by room.
Kitchen
Everything from a standard clean, plus: inside the oven, inside the refrigerator, sanitizing the trash can, wiping down all doors and door frames, disinfecting light switches and door handles, and cleaning kitchen decorative items.
Bathrooms
Everything from a standard clean, plus: scrubbing tile grout, cleaning inside the linen closet and shelves, wiping down baseboards, and dusting and wiping doors and door frames.
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, and cleaning inside linen closets and shelves.
Optional Add-Ons
A few high-detail items can be added to any deep clean at booking. Pricing is transparent and shown before you confirm. Inside the dishwasher and inside empty cabinets and drawers are each available as optional add-ons with pricing displayed at checkout.
If our team arrives and the home’s condition suggests the scope should change, we walk through it with you first and get your approval before any price is adjusted. No surprise charges after the fact.
Add-ons are priced individually so you’re not paying for things you don’t need. If you want the full deep clean treatment on the kitchen but your bathrooms were recently renovated and are already in good shape, the scope can reflect that. The goal is to match what the home actually needs, not a fixed package that doesn’t fit your situation.
When You Need a Deep Cleaning
Not every visit requires a deep cleaning. But there are specific times when a standard cleaning just isn’t enough.
Seasonal resets: Spring and fall are popular times for a Boulder deep clean 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. At Front Range elevation the air holds less moisture, so fine dust from trails, roads, and open space drifts inside and settles on settles on baseboards and window tracks between visits. 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.
First-time clients: We always recommend starting with a deep cleaning as your first appointment. 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, baseboards, and under furniture. needs targeted attention that a standard clean doesn’t cover.
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.
If any of these sound like your situation, book your deep clean online and see your price in about 60 seconds.

What to Expect on the Day of Your Deep Clean
| Before the Team Arrives | When the Team Arrives |
|---|---|
| You’ll receive a confirmation with your appointment details. If you have specific priorities, areas to avoid, or access instructions, you can include those at booking or message us ahead of time. No prep work is required on your end. You don’t need to clean before we arrive. | The experienced cleaning team does a brief walkthrough to confirm the scope and note anything you flagged. They bring all supplies and equipment. If anything looks different from what was booked, such as a larger space or heavier buildup in a specific area, they’ll mention it before starting, not after. |
| During the Clean | After the Clean |
| The team works room by room following the 75-point checklist. Deep cleans take longer than standard visits because the scope is broader. Most 2 to 3 bedroom homes take 3 to 5 hours, depending on the home’s condition. You don’t need to be home. If you’d prefer to be present, that works too. Either way, the checklist gets followed the same way. | You’ll receive photos of the completed work. If anything wasn’t right or you feel something was missed, contact us within 24 hours and we’ll come back to re-clean the areas you flagged at no charge. That’s the satisfaction guarantee in practice, not just in writing. |
Boulder-Specific Cleaning Considerations
Boulder County homes have a few characteristics that affect how a deep clean needs to be approached. These aren’t problems unique to one neighborhood. They show up consistently across the Front Range, and they’re worth knowing about before you book.
Hard Water Deposits: Boulder’s water supply has elevated mineral content. Over time, calcium and magnesium deposits build up on glass shower doors, and around drain hardware. Standard cleaning products don’t break these down effectively. Our teams use products matched to hard water environments, which is why the detail work actually produces results rather than just pushing the buildup around.
Dry Climate and Fine Dust: At Front Range elevation, the air holds less moisture. That means fine dust from trails, open space, and unpaved roads gets inside more easily and settles faster. It accumulates in window tracks, on baseboards, and along crown molding in ways that are easy to miss on a standard visit. Deep cleaning addresses these areas specifically rather than skipping them for next time.
Seasonal Pollen and Allergens: Boulder County’s outdoor environment means pollen and allergens come through windows and doors throughout spring and fall. If anyone in the home has allergies or respiratory sensitivities, a deep clean that covers baseboards and window tracks makes a noticeable difference in how the air feels inside the home.
Older Homes and Construction Styles: Many homes in Boulder, North Boulder, and the Hill area were built in the 1970s and 1980s. Older tile grout, original kitchen appliances, and period-specific fixtures need more careful product selection to avoid damage during cleaning. Our experienced cleaning teams know how to adjust their approach based on what they’re working with rather than applying the same products to every surface.
What Makes Our Deep Cleaning Different
Experienced Cleaning Teams OnlyEvery cleaner on our team has at least three years of professional experience. Deep cleaning requires knowing how to handle different surfaces, products, and appliance interiors without causing damage. Our experienced cleaning teams know what they’re doing.
Documented 75-Point ChecklistNot a rough estimate of what gets done. A room-by-room checklist that gets followed every time, so you know exactly what you’re getting. Review the full cleaning checklist here.
Background-Checked, Insured, and BondedEvery cleaner is vetted before they step into your home. We carry $1,000,000 per-occurrence general liability coverage, $2,000,000 general aggregate coverage, and $100,000 in fidelity bonding. 303 Crown Maids is also an active federal contractor registered through SAM.gov.

Pay Model Built to Keep Experienced CleanersWe pay our cleaning professionals 50 to 60 percent of every job. The industry standard is 30 to 35 percent. Higher pay attracts more experienced professionals and reduces turnover, which is why the same experienced cleaning team tends to come back to your home visit after visit rather than a new face each time.
Same-Day Payment to CleanersOur teams are paid the same day the work is completed. That reliability matters when you want the same people returning to your home and treating it like their own account, not a one-off shift.
We Bring All Supplies and EquipmentProfessional-grade products, proper tools for every surface. You don’t need to provide anything.
Satisfaction GuaranteeIf something isn’t right, let us know within 24 hours and we’ll come back and re-clean the areas you flagged at no extra charge. That applies to every deep clean, no matter the size of the job.
Founder-Led and Locally Operated303 Crown Maids was founded by Azur Ali, who built the company around transparent pricing, a documented checklist, and pay that keeps experienced cleaners in the field.
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, and your home stays at the level the deep clean established.
Most families who start with a deep clean continue with recurring service afterward, because the home is already at baseline and no additional setup is needed to keep it there. Your recurring experienced cleaning team already knows the home, and each visit is shorter and more focused than the first one.
Think of the deep clean as a one-time investment that makes every visit after it more efficient. When a team isn’t spending extra time on grout buildup, appliance interiors, or dusty baseboards that haven’t been touched in months, they can focus on keeping what’s already clean looking good. That’s a better use of time for everyone.
There’s also a practical financial benefit. Recurring clients pay a lower rate per visit than one-time bookings. Starting with a deep clean and moving to recurring service is the most cost-effective way to maintain a clean home over time, compared to booking individual one-time cleans every few months when things get out of hand.
This is how you stop the cycle of things building up and then needing another intensive reset every few months. When you’re ready to move to a recurring schedule, our standard cleaning services page walks through the frequency options and what’s covered.

Frequently Asked Questions About Deep Cleaning
What’s the difference between a deep clean and a standard clean?
A deep clean adds inside the oven and refrigerator, grout scrubbing, baseboards, doors and door frames, under furniture and beds, window frames, and crown molding. Inside cabinets and drawers and inside the dishwasher are available as add-ons. Full comparison on our checklist page.
How long does a deep cleaning take?
Most deep cleanings for a 2 to 3 bedroom home take between 3 and 5 hours. Homes that haven’t been cleaned in a while may take longer, and larger homes or homes with pets typically fall at the higher end of that range.
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. You can see your exact price and book online in about 60 seconds through our instant estimate.
How often should I get a deep cleaning?
For most homes, once or twice a year is enough if you’re also doing regular standard cleanings in between. Homes with pets, allergies, or heavy foot traffic may benefit from quarterly deep cleans.
Do you clean inside the oven and refrigerator?
Yes. Inside the oven and inside the refrigerator are both included in every deep cleaning visit as part of the kitchen scope.
Do you serve areas outside Boulder?
Yes. We serve homes across Boulder County and the broader Front Range including the cities of Longmont, Fort Collins, Lafayette, Louisville, Erie, Evergreen, Broomfield, Superior, Gunbarrel, Brighton, Denver, Loveland, Greeley, and Windsor.
Do I need to be home during the deep cleaning?
No. Most clients provide access instructions at booking and come back to a cleaned home. Every cleaner is background-checked, insured, and part of an experienced cleaning team, so you don’t need to be present for the work to be done properly. If you’d rather be home, that’s fine too.
What should I do to prepare for a deep cleaning?
No prep required. Just provide access and let the team know of any specific concerns or areas you’d like prioritized. If you want us to focus on the kitchen and bathrooms first, or leave a particular room untouched, tell us at booking or when the team arrives. For more answers, see our frequently asked questions.
