July in Boulder means summer schedules in full swing. College students are gone, families are home, and we've seen a noticeable uptick over the past four to six weeks in clients requesting first-time deep cleans before settling into a recurring schedule. Many of them have the same question: what is a deep clean going to cost me, and how is it different from what I'd pay going forward?
Those are fair questions. A deep clean is not the same service as a recurring maintenance visit, and the price reflects that. This post breaks down what a deep clean costs in Boulder, what variables change the number, exactly what is and isn't included, and when paying for specific add-ons actually makes sense for your home.
Boulder homes range from compact CU-adjacent studios near University Hill to large four-bedroom properties in South Boulder and Table Mesa. A deep clean priced for a 900-square-foot apartment is a fundamentally different job than one for a 3,500-square-foot home on South Boulder Road. The table below reflects what deep cleans actually cost across Boulder's housing range.
| Home Size | First-Time or One-Time Deep Clean | Recurring Initial Deep Clean (then drops to maintenance rate) |
|---|---|---|
| Under 1,000 sq ft | $160 to $210 | $145 to $190 |
| 1,000 to 1,800 sq ft | $210 to $285 | $190 to $255 |
| 1,800 to 2,800 sq ft | $285 to $375 | $255 to $335 |
| 2,800 to 4,000 sq ft | $375 to $480 | $335 to $430 |
| Over 4,000 sq ft | $480 and up | $430 and up |
The distinction between a one-time deep clean and a recurring initial deep clean matters. When a client sets up a biweekly or weekly schedule, the first visit is still a full deep clean from top to bottom. But because that client is committing to ongoing service, the initial visit is priced slightly lower than a pure one-time request. After the initial deep clean, subsequent recurring visits settle into the maintenance rate, which runs meaningfully lower per visit.
A pure one-time deep clean costs more per visit because there is no ongoing relationship reducing the upfront investment. The scope is the same. The time commitment from our crew is the same. The difference is in how the economics of the job work out for both sides.
For a direct comparison of what you'd pay on a recurring schedule versus a single deep clean over time, our post on recurring cleaning versus a one-time deep clean breaks down the annual cost math in detail. And if you are weighing where Boulder pricing sits relative to other Front Range markets, our post on house cleaning costs in Erie gives useful context on how location affects what you pay.
Square footage is the anchor, but several other factors shift the final number. Understanding these variables before you call or book means the quote you get reflects your actual home, not a generic range.
Bathroom count. Bathrooms take more time per square foot than any other space in a home. A full bathroom deep clean means scrubbing tile and grout, removing hard water deposits from fixtures, cleaning shower glass, addressing the toilet from base to tank, and wiping every surface including the vanity interior if accessible. Each additional full bathroom adds 25 to 40 minutes depending on size and condition. Older homes in North Boulder and the Whittier neighborhood often have original tilework and cast-iron tubs that require more careful product selection and more time per square foot than newer fixtures. A four-bathroom home of 2,200 square feet costs more to deep clean than a four-bedroom home of 2,800 square feet with two bathrooms.
How long since the last professional clean. A home that received a professional clean six months ago is a materially different job than one that has not been professionally cleaned in several years. Bonded soap scum on shower glass, grease buildup on kitchen surfaces, and mineral deposits from Boulder's moderately hard water supply all require extra product dwell time and more passes to lift properly. Homes coming out of a long gap between professional cleanings typically run 25 to 40 percent more time on site. Once that initial deep clean resets the baseline, any recurring visits that follow settle into the standard maintenance rate.
Pets. The hardest pet-related cleaning task is hair. Fine undercoat embeds into carpet fibers and collects in dense lines along baseboards and floor-wall transitions. It requires multiple vacuum passes and specific attachment tools to clear thoroughly. The impact varies by animal type and flooring. One short-haired cat on hard floors adds minimal time. Two large shedding dogs on carpet throughout a 2,400-square-foot home in Gunbarrel can add 35 to 50 minutes per visit. When you book, tell us specifically what animals live in the home so the quote reflects your actual situation.
Boulder's hard water and dust load. Boulder's water supply runs moderately hard, leaving mineral deposits on shower glass, faucets, and fixtures faster than in soft-water regions. Hard water scale requires an acid-based or chelating cleaner applied with dwell time to lift properly. Scrubbing without the right chemistry just scratches the surface and leaves the deposit behind. On top of that, Boulder homes near open space, particularly on the east side of the city toward Gunbarrel or along the western foothills, carry a higher ambient dust load than average. Fine particulate stays airborne longer in Colorado's semi-arid climate and settles back onto surfaces within days of cleaning. Our post on how Colorado's dry climate affects cleaning frequency explains this pattern and what it means for how often Boulder homes actually need attention.
Cleaning frequency going forward. This one surprises people. A client who books a deep clean and then signs up for biweekly maintenance will pay less per visit overall than a client who books monthly service. Monthly visits creep back toward recovery-level cleaning because four weeks of accumulation in an active household is significant. For families in South Boulder or Table Mesa who want consistent results without paying for a deep clean level of effort every time, biweekly service is almost always the better economic choice. The post on recurring versus one-time cleaning costs walks through this comparison with specific numbers.
A deep clean is not the same scope as a standard recurring visit. Here is exactly what is included in a Casabella deep clean in Boulder, with no add-on charge for the items listed below.
The sequence matters as much as the scope. Our crews work top to bottom in every room, every visit. Ceiling fans and overhead fixtures before mid-level surfaces, baseboards after everything above them, floors last. Cleaning in any other order means overhead debris falls onto areas already addressed. That sequence discipline is the difference between a home that looks clean and one that actually is.
The full scope of what we cover is on the Casabella services page. For clients who want to understand the difference between a deep clean scope and a standard recurring visit, the post on standard versus premium cleaning explains exactly where those scopes diverge.
A deep clean covers more than a standard maintenance visit, but several items still fall outside the included scope. These are available as add-ons priced separately.
Interior oven cleaning: $45 to $65. Baked-on grease in an oven requires a dedicated commercial oven cleaner applied and left to dwell before scrubbing. The job adds 30 to 45 minutes to the visit. It is not included in standard or deep clean scope because not every client needs it, and pricing it separately means you only pay for it when it is actually required. This is the most frequently requested add-on we receive from Boulder clients. If your oven has visible buildup, add it. If you are preparing the home for a showing or a tenant turnover, include it without question.
Interior refrigerator cleaning: $35 to $50. Refrigerator interiors collect spills, food residue, and odor in shelf channels, door gaskets, and under crisper drawers. Not included in deep clean scope. Worth adding before any home goes on the market, before a tenant takes occupancy, or when the interior has not been cleaned in several months.
Interior window glass cleaning: $55 to $100 depending on window count. Boulder gets over 300 sunny days per year. Dust, smear marks, and hard water spots on glass are highly visible in that light, particularly in west-facing rooms in Table Mesa and North Boulder where afternoon sun comes in direct and strong. Interior window glass is available as an add-on for a single visit or as a regular addition to your recurring schedule.
Move-out and pre-listing scope: priced per job. These visits go further than a standard deep clean. Cabinet interiors, all appliance interiors, window glass throughout, and a more thorough pass on every surface. These are quoted separately based on the specific home. For what those jobs run in Boulder specifically, our post on move-out cleaning costs in Boulder covers the pricing in detail. If you are listing a property rather than handling a tenant turnover, the post on preparing a home for sale with a professional cleaning covers the priorities that matter most to buyers and agents during showings.
The oven add-on earns its price in two situations. The first is any home going on the market or into a new tenancy. Buyers and landlords check oven interiors consistently, and the cost of the add-on is far less than what a dirty oven costs in price adjustments or deposit disputes. The second situation is any household with regular cooking. Adding interior oven cleaning once every two to three months for an active kitchen keeps it from reaching the point where it becomes a major scrubbing project.
Interior window glass is worth it when the windows face west or have clear Front Range views. Clean glass and a mountain view is what buyers are paying attention to in a Boulder showing. It also makes a noticeable difference in how a room feels day-to-day. For homes with significant glazing or picture windows, adding this seasonally makes sense.
The refrigerator interior add-on matters most for move-outs, pre-listing cleans, and homes that have accumulated residue over several months of use. For a recurring client on a biweekly schedule who wipes down the interior periodically, the add-on is not urgent. For anyone handing keys to a buyer or tenant, it belongs in the scope.
For Boulder homeowners still deciding between a deep clean as a starting point versus going directly into recurring service, our post on the best time to start a recurring cleaning service covers when that decision makes the most financial sense. And if allergens are a factor in how thoroughly your Boulder home needs to be cleaned, our post on cleaning for allergies on the Front Range explains why a deep clean baseline matters specifically in Colorado's dry climate.
You can reach us at 303-827-1251 during business hours and we will walk through your home's specifics, including square footage, bathrooms, pets, and any add-ons, and give you a confirmed price before anyone shows up. Our Boulder house cleaning page has more on how we work in this market and what clients in Gunbarrel, North Boulder, Table Mesa, and South Boulder typically ask for. You can also book your Boulder deep clean online and tell us exactly what your home looks like.
A deep clean in Boulder runs $160 to $210 for homes under 1,000 square feet and $285 to $375 for homes in the 1,800 to 2,800 square foot range. Larger homes between 2,800 and 4,000 square feet typically land between $375 and $480. These are one-time or first-time deep clean prices. Clients who set up recurring service pay a slightly lower rate for the initial deep clean, then move to the ongoing maintenance rate on subsequent visits. Bathroom count, pets, and the length of time since the last professional clean all affect the final number. The Boulder house cleaning page has more on how we scope and price work in this market.
A regular recurring maintenance visit covers the surfaces and rooms that need consistent attention: kitchen surfaces, bathrooms, floors, and dusting throughout. A deep clean covers all of that plus the areas that accumulate over time and require more focused effort. Grout lines in bathrooms, hard water deposits on fixtures and shower glass, the tops of door frames, cabinet hardware, light switch plates, window tracks, and the perimeter edges of every floor. A deep clean also takes longer because each room gets more thorough attention than a maintenance visit. In Boulder homes where the water supply leaves mineral deposits and Front Range dust settles fast, that deeper pass makes a clear difference. For a full breakdown of scope differences across service levels, see the post on standard versus premium cleaning.
Yes. The hardest pet-related cleaning task is hair, particularly the fine undercoat that embeds into carpet fibers and collects in dense lines along baseboards and floor-wall transitions. In Boulder homes with large shedding dogs on carpet, this adds 35 to 50 minutes to a deep clean visit compared to the same home without pets. Homes with one small short-haired animal on hard floors add minimal time. The type of animal, the coat, and the flooring in the home all factor into the additional time required. When you request a quote or book online, include the specific details about your pets so the estimate reflects your actual home. Discovering the pet situation at the door on the day of the first visit creates scheduling problems for the rest of the team's day.
Interior oven cleaning, interior refrigerator cleaning, interior window glass cleaning, and move-out or pre-listing scope are not included in a standard deep clean. These are available as add-ons. Interior oven cleaning runs $45 to $65 and is the most frequently requested add-on from Boulder clients. Interior refrigerator cleaning runs $35 to $50. Interior window glass runs $55 to $100 depending on window count. Move-out and pre-listing cleans involve cabinet interiors, all appliance interiors, and a more detailed pass throughout, and are quoted per job based on home size and condition. For what move-out cleans run in Boulder specifically, the post on move-out cleaning costs in Boulder has the full breakdown.
The most useful information you can give us upfront is your square footage, how many full and half bathrooms your home has, whether you have pets and what kind, when the home was last professionally cleaned, and whether you want any add-ons like interior oven or window glass cleaning. Quotes based on square footage alone miss variables like four full bathrooms or two large dogs that significantly change the time required and the final price. You can provide all of that detail when you book your deep clean online, or call and walk through it over the phone. Either way, you get a specific confirmed number before anyone arrives, not a range you find out at checkout. Our Boulder service page has additional context on how we work across Boulder's neighborhoods.
Put your Boulder deep clean on the schedule by booking online with the details about your home, and we will send you a confirmed price and scope before the first visit.
