There is an industry standard for how finished a drywall surface is, running from Level 0 to Level 5. Contractors quote against it constantly and mention it to homeowners almost never, which is how you end up comparing two quotes that are not describing the same job.
The levels, in plain terms
Level 0
Board hung, nothing else. No tape, no compound. Temporary construction only.
Level 1
Tape set in compound at the joints. Ridges and tool marks fine. Used in concealed spaces — above ceilings, in attics, in plenum areas. Often specified for fire-rated assemblies where the seal matters and the appearance does not.
Level 2
Tape plus one thin coat over joints and fasteners. This is a substrate level, not a finish — appropriate under tile, or in garages and warehouses where nobody is looking.
Level 3
Tape plus two coats. Suitable if a heavy texture is going over the top, which will hide the remaining imperfections. Not adequate under flat or eggshell paint.
Level 4
Tape plus three coats, sanded, joints and fasteners smooth. This is the standard for most residential work. Correct under flat paint, light textures such as orange peel and knockdown, and most wall coverings. If a quote does not say otherwise, this is almost certainly what you are getting.
Level 5
Everything in Level 4 plus a skim coat over the entire surface — a thin film of compound across every square inch, so the whole plane has uniform porosity and texture. Required for gloss and semi-gloss paints, dark colours, and anywhere strong raking light will cross the wall.
Which one do you actually need?
- Standard bedroom or hallway, orange peel texture, flat paint — Level 4. Anything more is money you do not need to spend.
- Modern smooth walls, flat paint, ordinary lighting — Level 4 will usually pass, but Level 5 is safer.
- Smooth walls with large windows, skylights, or wall-washing lights — Level 5, without question. This is the situation in a lot of Alamo, Blackhawk and remodeled Walnut Creek interiors, and it is where Level 4 quietly disappoints.
- Dark or saturated wall colours — Level 5. Dark paint magnifies every substrate variation.
- Gloss or semi-gloss anywhere — Level 5.
- Garage or workshop — Level 2 or 3 is plenty.
Why this makes quotes look wildly different
Level 5 on a whole-house remodel can add a substantial percentage to the drywall line, because skimming every surface is real additional labour and material plus another full sanding and drying cycle. A contractor quoting Level 4 against another quoting Level 5 will look dramatically cheaper while describing a visibly different result.
So when you collect drywall bids, ask every bidder one question: what finish level is this quote? If they cannot answer it immediately, that tells you something too.
Can you upgrade later?
Yes — a Level 4 wall can be skimmed to Level 5 afterwards. But it means bringing the crew back, another round of dust and drying time, and paying for mobilisation twice. It is far cheaper to specify it correctly up front.
