Prep work should include removing all loose paint, either with a pressure washer or by scraping; removing any trace of mildew using bleach and water or a commercial solution, and sealing or covering dark stains; caulking all seams, corners and around windows or trim; applying epoxy filler to repair serious woodwork problems; covering dark stains; sanding all rough surfaces, and priming the bare wood with a bonding primer.
One important consideration when comparison shopping for interior paint is the manufacturer’s available palette. One brand of latex paint may be significantly less expensive than others, but the tint options can be limited. There can also be a noticeable difference between one manufacturer’s “midnight blue” and another’s “Prussian blue.” There is no universal standard, so this is why sample cards and test paints are so important.
Paper/poly drop cloths: $2 to $6 for 9x12-feet. The best of both paper and plastic, these cloths are low-cost and disposable. They absorb paint drips while providing more protection for what's underneath. They also provide some protection from slipping. Plus, you can cut paper/poly drop cloths to fit the space. But, like paper, paper/poly drop cloths can rip more easily than plastic or canvas drop cloths.
After you have done the multiplication, subtract about 40 sq feet per window, and about 60 sq feet per door. Divide by 400 (interior paint covers 400 sq feet per gallon). The number that remains, is how many gallons you will need. If doing multiple wall colors, then you should do this process for each room (or sets of rooms) with a particular color.

The Ceiling. For ceilings, flat is recommended, except semigloss or satin should be used in bathrooms with showers/tubs. Some customers opt to go with a different finish for ceilings in general, to create a specific design look, i.e. high gloss ceilings on dining room tray ceiling to make a statement, or eggshell ceilings throughout to look modern and make a statement.
From dull to shiny finishes, paint comes in several different lusters. A paint’s luster depends on its mixture of pigment, resin, and additional ingredients. If you’re struggling to decide what finish you want, note that glossier finishes tend to be more durable and washable. Flat paint, on the other hand, is better at hiding surface imperfections. Pearl and eggshell lusters fall somewhere in the middle, as they are more washable than flat paint and partially hide irregularities.
Some siding on older homes might need so much repair that it is more cost-effective to replace the siding rather than repair it all and then paint over it. Expect to pay between $1,550 and $3,050 for the removal and disposal of old siding and $4,000 to $14,000 for new siding and installation. Expect to pay more if the wood underneath is wet and rotten and needs structural repair work.
Exterior paint averages $25-$40 a gallon, and a 3,000-square-foot home takes 15 or more gallons of paint, or $375-$600 just for the paint. However, really premium paint can cost $50-$100 a gallon, or $750-$1,500 for that large home. Doing it yourself also requires renting a pressure washer or sprayer for $50-$100 a day; extra-long ladders or scaffolding at $20-$75 daily; and a power sprayer for $50-$100 daily, plus masking tape, drop cloths and other supplies. However, it's possible to paint a large, two-story house for materials-only costs of $400-$600.
Paint supplies cost anywhere from $10 to $100 or more depending on what you need. Painters will typically provide most of the supplies for a project, but sometimes they will allow you to pay for solely labor if you provide all the materials yourself. You might decide to do a DIY paint job down the road. In which case having these supplies on-hand will save you time and money.
While you may choose to paint a door, ground-level window trim and other parts of your house’s exterior, it’s really a job best left to the professionals. One of the main reasons is experience. An experienced painter knows how to handle the prep work, spot problems and identify sources of future trouble, all while getting the job done more efficiently. They are also experienced with spending long hours on tall ladders. If you want high-quality work, it’s best to hire a professional painter near you.
