Interior House Painting Service: What Belongs in the Bid

The first interior house painting service to quote this house described the entire job in five words: “Paint walls, ceilings and trim.” Five words. For a week of somebody living in my house, moving my furniture, and putting a finish on every wall I look at every day.

I got three bids for the downstairs, and the spread between the cheapest and the priciest ran about forty percent. That part I expected. Two of the three describing the work in a single line is the part that still bothers me.

The third bid was two pages. It named the primer. It said which rooms got two coats and which got three. It said who was moving my furniture and who was patching the holes. It was the most expensive one, and it is the one I took.

A good interior house painting service is not selling you paint. Paint is the cheapest thing in the transaction. They are selling you preparation, product knowledge, and the discipline to come back and fix the eleven spots you find at night. Almost none of that shows up in a five word bid, which is exactly why the five word bid is cheaper.

This post is not about what painting costs. I already wrote that one, and if you want the numbers by room and by square foot they live in my interior painting cost breakdown. This is about what belongs in the bid, how to check the two credentials that actually matter, and the five questions I ask before anyone gets a deposit. I am not a licensed contractor. I am a homeowner who has hired painters four times, got it badly wrong once, and now reads every line.

What an interior house painting service should put in writing

A bid is not a price. A bid is a description of work that happens to end in a price.

When two companies quote the same rooms and one comes in thousands lower, the gap is almost never that one of them found cheaper paint. The gap is that one of them is planning to do less, and the five word scope is what lets them do less without technically breaking anything they promised.

Here is what I want named on paper before I sign. Which rooms, and which surfaces inside each room, because ceilings, closets and the inside faces of doors are the three things left out most often. The prep, described as steps. The product, by manufacturer and line. The number of coats. Who moves and covers furniture. A start date and a finish date. The payment schedule. What cleanup means and where the leftover paint ends up.

The Federal Trade Commission puts the same idea more plainly than I can. Its consumer guidance says a written estimate should include a description of the work to be done, materials, completion date, and the price, and warns you off contractors who want everything up front or take cash only.

One detail from that same FTC page surprised me, and it matters here because painting bids get signed at kitchen counters more than anywhere else. If you sign a contract in your own home rather than at the company place of business, the contract should include a written statement of your right to cancel within three business days. Signing at home is normal in this trade. That window is your out if you sleep on it and change your mind.

I am deliberately not relitigating deposits, licenses and the classic pressure tactics here, because I went through the anatomy of a fair quote and its red flags in is your contractor quote fair. Read that one for the general contractor rules. This post stays on the parts that are specific to paint.

The spec line almost no bid has: brand, line, sheen, coats

“Two coats of quality paint” is not a specification. It is a mood.

A specification is four things: the manufacturer, the product line, the sheen, and the number of coats, plus a note on where primer goes. All four matter, and the second one is the one homeowners never think to ask about. Every major paint brand sells a contractor grade line and a premium line under the same brand name. Same logo on the bucket, different product, and a bid naming only the brand has told you nothing about which one is going on your walls.

Sheen is the other thing worth pinning down, because it is a durability decision wearing an aesthetic costume. Flat hides wall imperfections beautifully and cannot survive a sponge. Higher sheens scrub well and show every ripple in the drywall.

Room	Sheen I ask for on walls	Why
Bedrooms, formal living	Matte or flat	Hides wall flaws, low traffic, rarely gets scrubbed
Hallways, stairwells, kids rooms	Eggshell	Takes hand prints and a damp cloth without burnishing
Kitchen, laundry	Eggshell or satin	Grease and splatter have to come off repeatedly
Bathrooms	Satin	Moisture tolerance matters more than hiding flaws
Trim, doors, cabinets	Semi-gloss	Wipes clean, takes knocks, separates visually from the wall
Ceilings	Flat	Kills glare and hides the roller lap lines you would otherwise see

What I ask for room by room. Preferences vary, and a good painter may talk you out of one of these for a reason. If they cannot give a reason, that is the useful signal.

Here is the mistake I actually paid for. On my first house I took the cheap bid to repaint a living room that had a dark accent wall. The crew rolled two coats of light grey straight over it and left. Looked fine that afternoon.

Within a month, every patched nail hole had come up as a dull halo, slightly flatter and slightly darker than the wall around it. That is called flashing, and it happens when patched or porous spots are not primed, so they drink the paint differently than everything around them. The bid had never said spot prime all patches. So it was not a defect. It was a thing they never agreed to do, and I never noticed was missing.

Ask for the sample on the wall, not the chip. A sample quart runs about $8 to $15 and buying two of them is the highest return money in this entire project. Paint a two foot square of each, two coats, on the actual wall in the actual room. Then look at it at ten at night with the lamps on, because that is when you live in the room, and north facing rooms in particular will turn a warm grey faintly purple after dark.

Insurance is the one thing you have to verify yourself

There are two policies you care about, and they cover two different disasters.

General liability covers damage to your property. Ladder through the picture window, sprayer overspray onto the car in the driveway, a gallon of semi-gloss down the stair runner. Workers compensation covers injury to the people doing the work. That second one is the one homeowners skip, and it is the one that can follow you, because an uninsured painter who falls down your basement stairs may come looking at your homeowner policy for the medical bills.

The FTC guidance says to consider only contractors who are licensed and insured, and to ask the contractor for proof of insurance. Correct advice, and it needs one practical addition, because asking the contractor is where this falls apart.

A certificate of insurance is a PDF. PDFs are editable, and the one emailed to you is a document the contractor is handing you about themselves. Do not accept a screenshot. Ask them to have their insurance agent send the certificate straight to you, with your name and address listed as the certificate holder, and check that it shows liability and workers compensation both. Any legitimately insured company does this constantly and their agent turns it around in a day. Five minute request. It filters out a whole category of problem.

I learned this by getting a screenshot once. It looked real. I only read the small print because I was procrastinating on something else, and the expiration date on it had passed fourteen months earlier. He had insurance, right up until he did not, and he was still sending out the old image.

If your house predates 1978, certification is not optional

This is the rule most homeowners have never heard of, and it covers a huge share of American housing.

Lead based paint was banned for residential use in 1978, and the EPA Renovation, Repair and Painting Rule governs work that disturbs paint in anything built before that. What surprises people is how squarely it lands on painters. The EPA lists special trade contractors, including painters, among the firms that require certification, and states that firms cannot advertise or perform covered renovation activities in pre-1978 homes without firm certification.

Interior painting is not a loophole. Sanding, scraping and even patching disturbs the existing paint, and the dust is the hazard. So the question for any pre-1978 house is short: is your firm EPA lead safe certified, and what is the certification number? A certified firm answers instantly, because they paid for the training and they use it to win jobs. Somebody who gets vague has told you what you needed to know.

If lead does come up, expect containment and cleanup to add to both the schedule and the price. My notes on exterior house painting and on painting kitchen cabinets both run into the same rule, because scraping siding and sanding old cabinet doors are two of the dustiest things you can do to an old house.

Prep is the scope that decides how the paint looks in year three

Anybody can roll paint on a wall. The difference between a job that photographs well and a job that still looks right after two winters is entirely in what happened before the first coat.

Real prep is a sequence, and I want it written as one: move and cover the furniture, mask trim and floors, fill nail holes and dings, sand those patches flat, caulk the gaps where trim meets wall, degloss or scuff sand any surface with a slick existing finish, spot prime every patch and any water stain, then paint, sanding lightly between coats on trim and doors.

Watch the ratio while they work. On the good job in this house, the crew spent a day and a half prepping and one day painting. That felt backwards to me at the time, and I remember thinking I was paying people to sand. I was. That is the job.

One boundary worth setting before you sign: real drywall damage is its own line item, not something a painter throws in. A cracked seam or a doorknob hole through the board is repair work with a drying schedule attached, and a painter who waves it off is either planning to skim it thin or planning to charge you later. The actual numbers for that work are in my drywall repair cost guide. And if painting is one trade inside a bigger remodel, the coordination question changes shape, which is what hiring a general contractor is for.

Five questions I ask every interior house painting service

These are ordered by how much they tell me, not by how comfortable they are to ask. The answers matter less than whether the answer arrives easily.

Who is physically on my job, and are they employees or subcontractors? Not a trick question, and there is no wrong answer. But the estimator who sells the job is often not the person who paints it, and I want to know whose hands these are and whether the person I have been talking to will be on site at all.
Walk me through your prep on this room, in order. A pro gives you the sequence without pausing, because it is what they do every day. Hesitation here is the single most useful thing I have learned to listen for.
What product line and sheen, how many coats, and what happens if the color needs a third? Dark colors and drastic color changes sometimes need three. I want to know now whether coat three is included or a change order.
What is your warranty in writing, and what voids it? Two years on workmanship is a common answer. The part people forget to ask is what voids it, which is where you find out whether they consider your walls their problem after they cash the check.
How does your punch list work, and when do you consider the job finished? The answer I want has them walking the rooms with me before the last payment. The answer I do not want is a shrug.

The walk-through, the punch list, and the last ten percent

The last ten percent of a paint job is where the money you held back does all of its work.

Do the walk-through twice. Once in daylight, once after dark with every lamp in the room switched on. Side light from a lamp rakes across a wall and shows roller stipple, missed cut lines and thin spots that midday sun washes out completely. On the last job I found four things at two in the afternoon and eleven more at ten at night, in rooms I had already signed off on in my head.

Take a roll of painter tape and stick a small tab beside every flaw you find. Do not try to describe them in an email. The tabs turn a vague argument about quality into a finite, countable list somebody can walk around and clear, and good crews prefer it that way.

Then three closing details. Hold the final payment until the punch list is cleared, which is the entire reason a staged payment schedule exists. Ask for a lien waiver when you make that final payment, so a subcontractor or supplier who did not get paid cannot later attach a claim to your house. And ask them to leave the leftover paint labeled by room, with the product line and sheen written on the lid, because in two years you will need to touch up a scuff and you will not remember a thing.

Interior house painting service bids, line by line

This is the table I wish somebody had handed me before my first bid. Left column is the line item. Middle is the version that shows up on a one page quote. Right is what I now want the paperwork to say.

Line item	What a vague bid says	What a real bid says
Scope	“Paint interior”	Room by room, listing walls, ceilings, trim, doors, closet interiors
Product	“Quality paint”	Manufacturer, the specific product line, and sheen per surface
Coats	“Two coats”	Two coats, plus what triggers a third and who pays for it
Primer	Not mentioned	Spot prime all patches, stains, and bare or glossy surfaces
Prep	“Prep as needed”	Fill, sand, caulk, degloss, listed as steps in order
Furniture	Not mentioned	Who moves it, who covers it, what you have to clear yourself
Drywall damage	“Minor repairs included”	Defines minor, prices anything past it as a separate line
Insurance	“Fully insured”	Certificate sent by their agent, naming you as certificate holder
Pre-1978 homes	Not mentioned	EPA lead safe firm certification number, containment described
Schedule	“About a week”	Start date, finish date, and daily working hours
Payment	Half down, half at the end	Staged schedule with a final amount held for the punch list
Completion	Not mentioned	Walk-through, punch list, lien waiver, labeled leftover paint

Use this as a checklist against a bid you already have. Every row a bid leaves blank is a decision somebody else gets to make later, usually while standing in your living room.

What quietly wrecks an interior paint job

Skipping primer on the patches. Costs almost nothing and takes an hour, and leaving it out is what produces those dull halos over every filled nail hole about a month after the crew drives away. It is the most common thing missing from a cheap bid.
Letting the color get chosen from a chip. A two inch chip under store lighting is not the same color as a wall in your north facing room at night. Two sample quarts and a day of looking prevents the expensive version of this discovery, which is repainting rooms you already paid for.
Paying in full before the night walk-through. Once the balance is gone you are asking for a favor instead of asking for the job. Everything hard to see shows up under lamp light, and that inspection has to happen while you are still holding the last payment.

Frequently Asked Questions

What should an interior house painting service include in the quote?
At minimum: the rooms and surfaces by name, the prep steps in order, the paint manufacturer and product line, the sheen, the number of coats, who moves furniture, start and finish dates, the payment schedule, and what cleanup covers. The FTC advises that a written estimate describe the work, the materials, the completion date and the price. If a quote is one line long, you are not comparing prices between two companies, you are comparing two different jobs.

How do I check that a painter is really insured?
Ask for a certificate of insurance sent directly by their insurance agent, listing you as the certificate holder, and confirm it shows general liability and workers compensation both. Do not accept a screenshot or a forwarded PDF, since those show only what the contractor chose to show you and can be long expired. Any properly insured company handles this request routinely, so friction here is itself an answer.

Does my painter need EPA certification?
If your home was built before 1978 and the work disturbs painted surfaces, yes. The EPA Renovation, Repair and Painting Rule requires firm certification, and the EPA specifically names painters among the special trade contractors it covers. Firms cannot advertise or perform covered work in pre-1978 housing without that certification. Ask for the number before work starts, not after.

How many quotes should I get for interior painting?
Three is the number I use, and the real value is not the price comparison. Reading three scopes side by side is what teaches you what a complete scope looks like, and the differences between them usually reveal exactly what the cheapest one left out. The FTC also warns against automatically taking the lowest bidder and suggests asking for an explanation when estimates land far apart.

Can I supply the paint myself to save money?
You can, and plenty of painters will allow it, but read the warranty first. Many companies will not warranty their workmanship over material they did not select, which means you have traded a modest saving for the thing you were hiring them for. Painters also buy at contractor pricing, so the saving is usually smaller than it looks from the shelf.

If you are still deciding whether to hire at all, the honest math on doing it yourself is in my interior painting cost guide, including the weekend I lost to a stairwell I should have paid somebody else to handle.

Tessa is a hands-on homeowner, not a licensed contractor, and nothing here is legal advice. Contract requirements, deposit limits, licensing rules and cancellation rights vary by state, so check your own state or county consumer protection office before you sign. Verify any contractor insurance and, for pre-1978 homes, their EPA lead safe firm certification directly rather than taking a document at face value.
