Late summer in Longmont has a way of making the inside of a house feel more neglected than it actually is. Between July Fourth gatherings, kids home all day, and the fine grit that blows off the plains east of town through August, a lot of homeowners in the Hover, Prospect, and Mountain View neighborhoods reach out to us in late summer wanting a reset before fall settles in. The question is almost always the same: what is this going to cost?
The honest answer is that deep clean pricing in Longmont depends on a handful of specific variables. Square footage matters less than most people expect. Bathroom count, the home's current condition, pets, and add-on choices drive the number more than raw size does. This post gives you real pricing grounded in the work we run in Longmont, explains what pushes a quote up or down, and tells you exactly what is included in a standard deep clean versus what costs extra.
The table below reflects current pricing for Longmont homes. These numbers are based on the jobs we run in this market, not national averages from a cleaning industry website.
| Home Size | Bathrooms | Typical Deep Clean Price Range |
|---|---|---|
| 2 bed / 1 or 2 bath | 1 to 2 | $190 to $265 |
| 3 bed / 2 bath | 2 | $260 to $335 |
| 3 bed / 2.5 or 3 bath | 2.5 to 3 | $315 to $395 |
| 4 bed / 3 bath | 3 | $370 to $455 |
| 4 bed / 3.5 to 4 bath | 3.5 to 4 | $425 to $520 |
| 5 bed / 4+ bath | 4+ | $490 to $620 |
Longmont's housing stock is more varied than most cities in Boulder County. You have older downtown homes near Main Street with original wood floors and claw-foot tubs, mid-century ranches in the Hover area, and newer construction in Mountain View and along the north end of town. A 1,900-square-foot older home with two bathrooms and original fixtures takes longer to clean than a 2,400-square-foot newer build with the same bathroom count, because older homes have more surface complexity, more grout, and more places where residue accumulates in ways that newer construction does not. That reality factors into how we quote.
Homes with finished basements step into the next tier up. A 3-bedroom, 2-bath Longmont home without a finished basement sits comfortably in the $260 to $335 range. Add a furnished, occupied finished basement and the same home moves to $330 to $405 because the basement adds floors, surfaces, and rooms that need the same level of attention as the main floors.
After a first-time deep clean, recurring maintenance visits are priced lower because the home is already at a clean baseline. Our post on recurring cleaning versus a one-time deep clean walks through that cost comparison with real numbers so you can decide which approach fits your situation.
These are the variables that account for most of the price differences between Longmont homes that look similar on paper.
Bathroom count is the biggest driver. Bathrooms take three to four times the cleaning time per square foot that a bedroom or living area requires. A 2,200-square-foot Longmont home with three full bathrooms costs more to deep clean than a 2,800-square-foot home with two bathrooms. Most people assume size drives the quote. Bathrooms drive it more.
Condition of the home matters more than people expect. A home that was professionally cleaned two months ago and has been reasonably maintained since is a different job from a home that has not had a deep clean in 18 months. Both might be the same size and layout, but the second one has accumulated residue in grout lines, on baseboards, in fixture channels, and on appliance interiors that requires product dwell time and focused effort to reverse. When we ask during a booking conversation how long it has been since the last professional clean, that question directly affects the quote.
Pets add time at every surface level. Pet hair collects along baseboards, in HVAC vent covers, on upholstered furniture edges, and in corners throughout the home. One dog or cat typically adds 20 to 30 minutes to a standard deep clean. Two or more pets can add 45 minutes to an hour depending on breed and how much of the home they use. Telling us about pets when you book lets us quote accurately rather than giving you a number that changes on arrival.
Older Longmont homes have specific surface considerations. Downtown homes near Prospect and the older blocks off Main Street often have original tile grout, older caulk lines, and painted wood trim that requires more time per linear foot than modern surfaces. Cast iron or old porcelain fixtures take longer to bring back to a clean finish than newer acrylic tubs. These are not problems, just honest variables that affect how long a thorough deep clean takes.
Home size above 3,500 square feet changes how we approach the quote. Our post on pricing for larger homes in Erie and Broomfield covers what changes at that threshold. The same factors apply in Longmont.
A standard deep clean at Casabella covers the full home at a thorough level. Here is what is included without any additional charge.
Kitchens: Countertops wiped and sanitized. Stovetop cleaned including burner grates. Exterior surfaces of all appliances. Cabinet and drawer faces wiped. Sink and faucet scrubbed and descaled. Backsplash wiped. Floor cleaned including under movable items near the perimeter.
Bathrooms: Toilet scrubbed inside and out, including the base, tank top, and seat hinges. Shower and tub cleaned including tile, grout surfaces, glass, and fixture hardware. Sink and faucet scrubbed. Mirror cleaned. Vanity surfaces wiped. Floor cleaned. Exhaust vent cover wiped down.
Bedrooms and living areas: All accessible surfaces dusted from top to bottom, including ceiling fan blades, light fixture surrounds, and window sills. Baseboards wiped throughout. Door frames and handles wiped. Floor vacuumed or mopped depending on surface type. Window mirrors and glass surfaces cleaned.
Entryways and hallways: All flat surfaces dusted. Baseboards wiped. Floor cleaned. Light switch plates wiped.
A first-time deep clean goes meaningfully deeper than a standard maintenance visit. We spend extra time on surfaces that have accumulated residue over time, including inside window tracks, behind toilet bases, along the full baseboard run, and on all appliance exteriors. A typical first-time deep clean on a 3-bedroom, 2-bath Longmont home takes around four hours. A biweekly maintenance visit on the same home in good condition runs closer to 2.5 hours. Monthly clients make up the majority of our recurring schedule in Longmont, and the pattern holds the same way whether visits are biweekly or monthly: the first visit takes the most time, and maintenance visits after that are faster because the baseline has already been established.
Several tasks are not included in the standard deep clean but can be added at booking. These are the most commonly requested in Longmont homes.
For move-out or pre-listing situations, the total scope often includes several of these together. Our posts on move-out cleaning costs in Loveland and move-out cleaning costs in Boulder cover how add-on selection affects the final price for that type of job. The same logic applies in Longmont.
Not every add-on makes sense for every home. Here is a practical way to think through the ones that come up most often.
Interior oven cleaning is worth it if the oven has visible baked-on residue and has not been cleaned in six months or more. Attempting it yourself with standard oven cleaner produces fumes, requires multiple applications, and rarely reaches the door glass channel or back corners as thoroughly as a professional pass. If the oven is in reasonable shape, skip it and maintain it yourself going forward.
Interior refrigerator cleaning is worth it for households with young children, heavy produce use, or any visible residue in drawer channels. The gasket seal around the door is one of the highest-bacteria-density surfaces in most kitchens and is almost never cleaned during routine home maintenance. If the refrigerator has any smell when you open it, this add-on is money well spent.
Interior cabinet cleaning is worth it in two situations: before listing a home for sale, and when moving into a home where you do not know the previous owners' habits. The cost reflects the real time involved. For most active kitchens on a recurring cleaning schedule, it is reasonable to skip it.
Interior window cleaning is worth it seasonally. Longmont sits in a dry, windy corridor, and by late summer, the interior window glass in homes on the north and east sides of town often carries a visible haze from months of grit infiltration. Adding interior window cleaning to a late-summer or early-fall deep clean gives you clean glass going into the lower-light months of October and November, when you notice window clarity more than you do in bright summer. Our post on how Colorado's dry climate affects cleaning frequency explains why this seasonal accumulation is more pronounced on the Front Range than in most other markets.
Wall spot cleaning is worth it before any real estate showing or family gathering where fresh paint would be overkill but scuffed walls would stand out. In Longmont's older homes downtown, painted wood trim and wall surfaces near high-traffic corridors accumulate scuffs faster than newer homes with harder paint finishes.

A standard deep clean for a 3-bedroom, 2-bath Longmont home typically runs between $260 and $335. Homes with 2.5 or 3 bathrooms in the same bedroom count move to $315 to $395. Bathroom count is the single biggest pricing variable, not square footage. Bathrooms take significantly more cleaning time per square foot than other rooms. Current condition also matters. A home that has not been professionally cleaned in over a year, or one with older original fixtures common in Longmont's downtown and Hover neighborhoods, falls toward the higher end of the range. Add-ons like interior oven cleaning ($40 to $60) or interior refrigerator cleaning ($45 to $65) are priced separately. For a broader cost comparison, our post on recurring cleaning versus a one-time deep clean walks through how first-time deep clean pricing compares to ongoing maintenance visit pricing with real numbers.
A deep clean in Longmont covers the full home at a level that goes beyond what a standard maintenance visit addresses. It includes detailed work on baseboards throughout the home, ceiling fan blades, window sills and tracks, appliance exteriors, stovetop including burner grates, toilet base and seat hinges, shower grout and fixture hardware, exhaust vent covers, light switch plates, and door frames. A standard maintenance visit covers the same rooms but allocates less time per surface because the home is already at a clean baseline from a prior deep clean. A first-time deep clean on a typical Longmont 3-bedroom home takes around four hours. A biweekly maintenance visit on the same home in good condition runs closer to 2.5 hours. Interior appliance cleaning (oven, refrigerator, cabinet interiors) is a separately priced add-on for both visit types. See our Longmont house cleaning page for how we structure first-time visits in this market.
Yes. Pet hair collects along baseboards, in HVAC vent covers, on upholstered furniture edges, and in corners throughout the home in a volume that adds meaningful time to the visit. One dog or cat typically adds 20 to 30 minutes to a standard Longmont deep clean. Two or more pets in a home where they have access to all rooms can add 45 minutes to an hour depending on breed and coat type. When you book, letting us know how many pets you have and which rooms they use helps us quote accurately rather than adjusting the price after we arrive. Longmont homes with dogs that have yard access through a back door tend to have higher floor and baseboard accumulation rates near those entry points than the rest of the house.

For most Longmont home sales, a professional deep clean before listing is worth the cost. Buyers and their agents notice cleaning quality during showings, and a home that presents well at first impression supports the asking price. The add-ons that matter most for a pre-listing clean are interior cabinet cleaning (buyers open cabinets), interior appliance cleaning, and wall spot cleaning for visible scuffs. Interior window cleaning added to a pre-listing deep clean is particularly useful in Longmont because late-summer and fall light at lower angles reveals window haze that summer overhead light hides during photography. Move-out cleaning scope is similar to pre-listing in most cases and is priced comparably. Our post on preparing a home for sale with professional cleaning covers the decision framework in detail, and the same considerations apply to Longmont listings. You can book online and note that it is a pre-listing clean so we scope it correctly from the start.
The most accurate quotes come from a brief conversation covering four things: bedroom and bathroom count, square footage or a general description of the home's layout, when the home was last professionally cleaned, and whether you have pets. Those four variables account for most of the price differences between Longmont homes of similar size. Add-ons like interior oven or refrigerator cleaning can be discussed at that point or added at booking. We do not require an in-home estimate for most Longmont deep cleans. For larger homes above 3,500 square feet, our post on pricing for larger homes in Erie and Broomfield covers what changes at that size threshold. The same variables apply in Longmont. Visit the Longmont house cleaning page for a general overview, or book online and we will follow up to confirm pricing before scheduling anything.
