Comparing carpet cleaning bids: line them up before you choose
Carpet cleaning bids rarely describe the same job. Here is how to set them side by side line by line, what to ask each bidder and which gaps deserve a second look.

Read the work before the totals
When three carpet cleaning bids arrive, the eye goes straight to the bottom line. That is the one number that tells you least, because each total prices a different set of work. One bid includes pre-vacuuming, spotting and moving furniture; another treats them as extras. One names hot water extraction for every corridor; another proposes a surface pass on the same floors. Until the bids describe the same job, the totals cannot be compared at all.
The fix is simple and a little tedious: copy every bid onto one sheet, line by line, before you look at what each one costs. Where a bid is silent on a line, write “not stated” and ask. The Carpet and Rug Institute’s advice to buyers points the same way. It suggests measuring your space, comparing by area rather than by room count, and checking what your carpet warranty requires of cleaning before you choose. The printable comparison sheet on this page gives you the columns to do it.
The comparison table
Each row below is a line that commonly differs between commercial carpet bids. Use the What to compare column to fill in your sheet, the What to ask column for follow-up calls, and the Red flag column to mark bids that need a second conversation.
| Bid line | What to compare | What to ask | Red flag |
|---|---|---|---|
| Method | The method named for each area | Why this method for this carpet? | “Clean carpet” with no method named |
| Frequency | Deep and interim visits per year, by zone | Which areas get more visits, and why? | One interval for lobby and back office alike |
| Preparation | Pre-vacuum, spotting, gum and lane pre-treatment | Is each step in every visit? | Preparation left out or listed as extra |
| Furniture and mats | What gets moved, returned and protected | Who moves desks, and are mats cleaned? | Furniture handling never mentioned |
| Products | Cleaners named, and limits your warranty sets | Which products, and do they fit our carpet? | Products described only as “professional grade” |
| Insurance and crews | Certificate, coverage types, crew screening | Can we see the certificate before signing? | No certificate offered until after signing |
| Supervision and sign-off | Inspections, sign-off step, return window | Who inspects, and how are misses fixed? | No inspection or fix-up step at all |
A red flag is a prompt for a question, not an automatic rejection. A bidder who left furniture off the page might include it as a matter of course. The point is to get that answer in writing, so the bid you sign describes the work you expect.
Method and frequency carry the most weight
Two bids for “twice a year” can deliver very different carpet. Hot water extraction flushes soil from the base of the pile; bonnet cleaning works the top of the pile and suits frequent appearance visits between deep cleans. Both have a place in a program, but a bid built only on one of them is a different product from a bid that combines them. Check that each bid names a method for each area and a number of deep and interim visits for each traffic zone.
Then hold each method plan up against your warranty. No two manufacturers write the same terms, and they vary by product too. Interface’s published maintenance guide, as one case, names hot water extraction as its only restorative method and says that rotary or bonnet cleaning “may void all warranties”; rotary equipment on carpet is also something CRI 204 does not recommend. Pull out your own warranty, turn to its maintenance section and give a copy to every bidder, so each method plan is built to fit it rather than assumed to.
What is included, and what is billed as extra
The lines most often left vague are the ones done before and after the main cleaning. Public carpet specs show how much they matter: Rhode Island’s statewide bid requires vacuuming, spot and gum removal and traffic lane pre-treatment before cleaning, and has crews move chairs and small tables, put them back and block furniture set on damp carpet. A bid that skips those steps is pricing less work, whatever its total says. Our carpet cleaning scope of work template walks through the rest of that spec line by line.
- Pre-vacuuming before deep cleaning, and on which areas
- Spot and gum removal, and spot calls between visits
- Moving furniture, putting it back and protecting it
- Entrance and walk-off mats cleaned or left out
- Air movers or other drying equipment brought to the site
- Carpet protector, where you asked for it
Insurance, crews and supervision
Ask every bidder for a certificate of insurance before you sign, and read what it covers. Look for workers’ compensation and liability coverage, and check the dates it runs. Then compare how each company screens the people who will be in your building after hours, and who checks their work. A bid that names a supervisor and describes an inspection is promising something a bid without one is not.
Note how each bidder plans to schedule. Evening, weekend and between-booking windows matter in occupied buildings, and the bid should say which areas will be done when and how soon each one reopens.
Sign-off and the written record
The last lines to compare are about what happens after the crew leaves. Does the bid include a walk-through with your contact, a sign-off before billing and a window to return and fix anything missed? A dated record of each visit, listing areas, method and products, is also worth asking for, since it helps when a warranty question comes up later.
How our written quote lines up
We start every bid with a free walkthrough, measure the carpet ourselves and read any warranty or bid package you share. The written quote then lists each area with its method, its frequency, the preparation and mat work included and how furniture is handled, so it drops straight into your comparison sheet. The insurance and crew rows fill in quickly for us: a certificate of insurance for every client, insurance and bonding with workers’ compensation, background-checked crews and supervisor quality inspections. Book a walkthrough and add our quote to your sheet.
A few useful answers
Common questions.
How do you compare commercial carpet cleaning bids fairly?
Put every bid on one sheet, line by line: method and frequency for each area, preparation, furniture, mats, products, insurance, supervision and sign-off. Compare totals only once the bids describe the same scope.
Why are carpet cleaning bids for the same building so different?
Because they usually describe different work. Bids differ on method, the number of deep and interim visits, whether pre-vacuuming, spotting and moving furniture are included, and how much square footage the bidder measured.
Is a bonnet cleaning bid comparable to an extraction bid?
No. Bonnet cleaning is an interim method that works on the top of the pile, while hot water extraction is a restoring clean. Compare a bonnet bid with other interim proposals, or ask each bidder for a combined plan.
What documents should come with a carpet cleaning bid?
A written quote listing areas, methods and frequency, a certificate of insurance, a description of crew screening and supervision, and the steps for sign-off and fixing missed areas.
Should every bidder see our carpet warranty?
Yes. Every manufacturer sets its own terms, which also change from product to product, and some limit the methods or cleaners used. Sharing the maintenance section lets each bidder fit its method plan to your carpet.
