While many professionals use paint sprayers, they can leave drips and uneven coatings in the hands of an inexperienced user. If you’re set on DIY house painting but don’t have much practice, you may want to stick to rollers and brushes. Brushes are great for edges and smaller areas, while rollers can be used to paint large and long surfaces like siding and trim.

The average cost to paint the interior of a house or room is $1 to $3 per square foot. Painters charge $1,200 to $3,900 to paint the walls in a house interior, and the cost to paint a room is $350 to $850. Prices increase when including the ceilings, baseboards, and trim.

Oil-based paint is commonly used for high-moisture areas, such as bathrooms and kitchens, and floors, trims, and moldings, since these areas take more abuse over time than walls do. Typically oil-based paints are less expensive than latex paints, take longer to dry, can create bad odor while drying, and contain more volatile organic compounds (VOCs), which essentially means they're less environmentally friendly.
If the exterior of your home is unpainted or has been scraped and sanded, you will want to lay down a coat of primer. Make sure that the primer you’re using is right for the surface you’re painting. While most surfaces can be treated with acrylic primer, some surfaces, like cedar and redwood, require oil-based primers. The oil stops the wood tannins from bleeding through the topcoat.
Begin prepping your walls by removing any outlet covers or lighting fixtures (if possible). Next, inspect your walls for any defects. If you encounter cracks, dents, or holes in your walls, simply fill them in with caulk or spackling compound. There are also a number of DIY tips to fill nail holes. Once your repairs dry, smooth them down with sandpaper and wipe the walls down with a damp sponge.
Many new homeowners want to change the color scheme of their rooms, either as a way to personalize the space or match the walls with existing furnishings and artwork. Interior house paint is relatively inexpensive, and it doesn’t require complicated machinery or professional-level skills to apply. There are also thousands of customizable colors available, as well as a choice of finishes, such as matte, semigloss, or gloss.
The average cost to paint a house exterior is $2,500 for a 2,400 sq. ft. two-story home, with most homeowners paying between $1,800 and $3,200. The final cost comes out to around $0.60 to $1.60 per square foot. With so many variables in pricing, you need to take them all into account before coming to your own estimate on how much your painting project will end up costing.
However, some water-based paints are easier to work with than others. The first coat of paint may not provide complete wall coverage, or the color may not be quite as saturated. Some of these problems can be addressed with a separate primer coat, but this is a time-consuming project. The ideal solution is using a higher-quality paint that combines a primer and a finish paint in a “one coat” product.

Test different paint swatches. The last thing you want to do is paint a whole room and then decide you despise the color (yes, it happens!). Try out different paint colors on the surface before choosing the paint that you want. Buying sample sizes will help you save money. The caveat: paint color samples are not real paint, so if you try to finish or touch up a project with samples, the paint will fade.

Of course, paint brushes and rollers are also important line items on your budget sheet. A 3-inch-wide paint brush costs, on average, $10 to $20—though you'll likely need an assortment of paint brush sizes for trim, corners, and narrow surface areas. Brushes come in a variety of bristle types and qualities, and each has a different purpose. Some are intended for specific paint types, finishes, and surfaces, so be sure to buy the right brushes for your painting job.
Priming is compulsory if you're painting over a darker color, or on a new drywall, but it's a good idea to include this step before any paint job. A primer is necessary because it blocks any stains from bleeding through. It is also important because it prevents any blisters and paint-peeling by improving paint adhesion. Lastly, primer is a good idea as it allows complete single-coat coverage of the walls. If you want a better appearance, you can tint your primer with the final color you intend on using on the walls. Most paints today come with inbuilt primers, but an old school primer is still a better option. Before you start painting, remember to use painter's tape to cover your door frames, window sills, and any switches on the wall.
A gallon of paint costs $15 to $40 and covers about 350 square feet with one coat. Designer varieties can run over $100 per gallon. Your contractor pays 50 percent less than what it runs in a home improvement store. You’ll also need to spend another $20 to $100 on supplies like brushes, rollers, masking paper and plastic. A professional will have these items on-hand.
If you have kids, pets, or occupants who will damage the walls, it is recommended to go with washable matte, eggshell, or satin, because these paints can be easily cleaned and are more durable. However, flat paint can be touched up more easily and hides imperfections better, so if you are selling the home, it is highly recommended to go with flat. Bathrooms with showers/tubs should go in semigloss- unless you are selling or want a specific design look, then use satin.

High-gloss paint is the most durable and easiest to clean of all paint sheens. It's ultra-shiny, light-reflective, and hard (think appliance-paint tough). High-glass paint has too much shine for interior walls; you'd find the reflections and drywall flaws distracting. It is a good choice for areas that sticky fingers touch, though, such as cabinets, trim, and doors.
Similar to exterior mold, mold is more likely to emerge in warm and humid areas. That being said, rooms like bathrooms and basements are more prone to mold. To preemptively prevent mold, use paints that are mold resistant. Should you find mold on a wall in your home, you can clean it with a simple solution of one part bleach to four parts water. If the area is large, you may want to leave the cleaning to a professional.
Stripping – $54–$151/100 sq. ft.. “The principle of paint strippers is penetration of the paint film by the molecules of the active ingredient, causing its swelling; this volume increase causes internal strains, which, together with the weakening of the layer's adhesion to the underlying surface, leads to separation of the layer of the paint from the substrate.”— Wikipedia. All the stripper will do is soften the paint. You’ll still have to scrub or scrape it off.
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.
Most house painting professionals will agree that two coats of paint are needed on a home. Using one coat of paint may look sufficient, but will not hold up over time. Two coats of paint, on the other hand, provide protection, washability, and help retain the true color of the paint. If you are still toying with the idea of hiring a professional painter, ask if two coats of paint are included in the pricing estimate.

Each type of siding will need to be treated differently when it comes to primer and paint at different price points. Exterior paint costs between $35–$80 per gallon depending on the quality you choose. It’s not always true that the more you pay for your paint, the longer-lasting your paint job will be, but you do need to be careful when researching exterior paints to make sure it can weather the local elements well.

06/14/17: Renato completed an exterior painting project for our relatively large single family home in Stamford, CT last weekend. Project did not begin well especially with the prep, repair/carpentry work, but then Renato took full control and ensured that the work done was to our satisfaction. The final result is outstanding. Minor damage to window screens, gutters and plants. Ensure that your window screens, gutters, and shutters are numbered and stored indoors or if kept outdoor covered properly against the elements. The project can be extensively delayed due to rain and you may find yourself dealing with insects and/or flooding in basement and dirty/bent/ mismatched screens/gutters/shutters. Overall we had a good team working on our project and we are satisfied with the finished product. The house looks great!
