How much a deep clean of a house costs depends on condition first, then size, surfaces, add-ons and access. A deep clean is priced as one long reset, not as a routine visit, so the real question is how much has collected since the last thorough pass. The only accurate number is a quote built for your home.
This guide carries no dollar figures. Published averages mix a one-bedroom condo with a four-bedroom colonial, and a kitchen that was deep cleaned last spring with one that never has been. What is useful is knowing what the quote is actually made of.
What goes into a deep cleaning quote?
Time, and nearly every factor below is a question about hours. Square footage sets the floor. Condition decides how far above that floor the job lands.
| Factor | How it moves the quote |
|---|---|
| Time since the last thorough clean | The widest swing between otherwise identical homes. Build-up lives on baseboards, door frames, sills and grout. |
| Number of bathrooms | The slowest rooms per square foot. Showers, glass, grout and fixtures are hand work. |
| Kitchen condition | Grease on cabinet fronts, the hood exterior and the backsplash does not wipe off in one pass. |
| Square footage and layout | More floors mean more stairs, more trim and more carrying. |
| Water hardness | Mineral film on shower glass, tile and faucets needs a slower, gentler method. |
| Surface materials | Natural stone, unsealed wood and painted woodwork each limit what can be used on them. |
| Items on surfaces | A covered surface cannot be cleaned, and clearing and replacing things takes time. |
| Pets | Hair collects along baseboards, under furniture edges and on upholstery. |
| Add-ons | Oven and refrigerator interiors, inside cabinets and similar tasks sit outside the base scope. |
| Access | Parking, stairs, a single bathroom still in use and a fixed window of hours all shape the day. |
Why does condition matter more than square footage?
Because a deep clean is measured in build-up, not in floor area. Two 2,000-square-foot homes can be a different job entirely, and the difference is usually how long it has been since anyone reached the edges.
A home that has been cleaned every two weeks for years already has clean baseboards, clean door frames and clear shower glass. The deep clean there is mostly detail and reach: light fixtures, vents, the tops of cabinets, behind what can be safely moved.
A home on its first thorough clean in a decade carries all of that at once. Grout, hinge edges, window tracks, the strip of floor behind the toilet and the seam where the counter meets the backsplash are each a separate small job. This is why a quote asks when the home was last deep cleaned before it asks how big it is.
How much does a deep clean of a house cost per hour?
An hourly rate on its own tells you very little about a deep clean, because the hours are the unknown. Some cleaners quote by the hour, some set a flat price for a written scope, and for a one-time reset the flat quote is the easier of the two to compare.
With an hourly rate, ask for an estimated range and what happens if the work runs past it. With a flat rate, ask exactly which rooms and tasks the number covers. Either way, the figure is only meaningful next to a scope. The broader trade-offs between hourly, per-square-foot and flat pricing are covered in what drives the price of house cleaning.
What is included in the price, and what is an add-on?
A deep clean covers the rooms and reachable surfaces, worked top to bottom. A short list of tasks is normally quoted on its own, because the time they take depends entirely on what is found inside.
- Inside the microwave. Part of the cleaning, not an extra.
- Oven and refrigerator interiors. Add-ons, quoted by the condition of the appliance. A lightly used oven and a neglected one are different jobs.
- Inside cabinets and pantry organization. Arranged separately, shelf by shelf.
- Carpet cleaning, grout restoration, floor refinishing. Other trades, not cleaning.
- Exterior glass, garages and outbuildings. Separate access and separate equipment.
The full room-by-room scope is in what a deep clean of a house includes. Confirm your own list in writing either way, because scope is where two quotes usually differ.
Supplies are a real cost whichever way they are handled, so ask whether they are in the price and what will be used. The EPA's Safer Choice label is one reference point: the agency says every ingredient in a labeled product must meet strict safety criteria for human health and the environment, and that labeled products must perform comparably to conventional ones.
What should a deep clean cost compared with regular cleaning?
More than a regular visit, and the gap is widest the first time. A recurring visit maintains a standard that already exists; a deep clean creates it, which means reaching surfaces a routine pass is not scheduled to touch.
That is why many cleaners start every new client with a deep clean and move to a weekly, bi-weekly or monthly schedule afterwards. Once the home is reset, each later visit covers less accumulation and becomes more predictable to price. The difference in scope between the two is set out in deep cleaning vs regular cleaning.
What do New England homes add to the job?
Three things show up here more than elsewhere, and each one is time rather than a surcharge.
Water hardness is the first. The USGS defines hardness as the amount of dissolved calcium and magnesium in the water, and it varies from town to town and well to well. In hard water, soap reacts with the calcium to form soap scum, glass is left with spots or film, and heating the water forms solid calcium carbonate deposits. On shower doors, tile and faucets that means a mineral layer a normal pass does not remove.
Stone is the second. Where a bathroom has marble, limestone or travertine, the quickest descaling methods are off the table. The Natural Stone Institute warns that products containing lemon, vinegar or other acids may dull or etch calcareous stones and that scouring powders and creams often contain abrasives that may scratch, recommending instead a neutral cleaner, stone soap or a mild liquid dishwashing detergent and warm water, rinsed thoroughly and dried with a soft cloth. For buildup it advises a non-acidic soap scum remover. Slower work, by hand, on surfaces that cannot be redone.
The third is the housing stock. Many homes across Southern New Hampshire and the Merrimack Valley have deep window sills, stair spindles, panelled doors and detailed baseboards that are all dusted and wiped by hand. Add road salt and slush from November through April and spring mud at the entries, and the first reset of the year runs longer than a summer one.
How do you get a deep cleaning quote that holds?
Send enough detail that nobody has to guess. Most quotes that change on the day were built on a description that left something out.
- Square footage, the number of bathrooms and the number of floors.
- When the home was last cleaned thoroughly, honestly stated.
- Floor and counter materials, naming any natural stone or unsealed wood.
- Photos of each bathroom, the kitchen and any room you are unsure about.
- Which add-ons you want quoted: oven, refrigerator, inside cabinets.
- Pets in the home, and anything that needs particular handling.
- Access details: parking, stairs, entry arrangements and the days that work.
How do you compare two deep cleaning quotes?
Compare the written scope, not the totals. The FTC's guidance for home projects applies cleanly: a written estimate should include a description of the work to be done, the materials, the completion date and the price. It also advises getting more than one estimate, not automatically choosing the lowest bidder, and asking for an explanation when there is a big difference between them.
Three questions make two numbers comparable: which rooms and surfaces are inside the price, which tasks are add-ons and how they are priced, and what happens if the home needs more work than the quote assumed.
How Andemora quotes a deep clean
Andemora Cleaning has cleaned homes in Southern New Hampshire and the Merrimack Valley since 2020, and every new client starts with a Deep Cleaning. The quote is built from the home itself: size, condition, surfaces and the add-ons you choose.
Inside the microwave is included. Inside the refrigerator and inside the oven are add-ons, quoted by the condition of the appliance, and inside cabinets or pantry organization are arranged separately. Supplies are included, and the products are safe for kids and pets.
Every visit follows the Triple-A Standard and ends the same way: each room re-checked against the checklist under room light and natural light, then lights off, doors locked and a message that the home is ready. For a number that fits your home, request an estimate.
Frequently asked questions
Is a one-time deep clean priced differently from the first visit of a recurring plan?
The work is the same, so the quote is built the same way. What changes afterwards is the schedule: if recurring visits follow, the home stays close to that level and later visits are shorter.
Do I need to buy cleaning products?
Not when supplies are part of the service. If you want a specific product used on a particular surface, say so when you ask for the quote and leave it out for the visit.
Can I deep clean only part of the house to lower the price?
Yes. A deep clean can be scoped to the kitchen, the bathrooms and a few rooms rather than the whole home. Agree the room list in writing so nothing is assumed on either side.
Will the price change on the day?
It should not, if the scope was described accurately. Ask in advance what happens when a home turns out to need more than the quote covered, so you learn the answer before it matters.
Does a deep clean cost more than a move-out clean?
Not as a rule. The scopes overlap heavily, and the difference comes from condition and from whether the home is empty. An empty home is faster to clean than a furnished one.
