Repainting is key to maintaining exterior house paint. The material that your home is made of affects how often you should repaint. For instance, wood-paneled homes need to be repainted twice as often as those made of stucco. Environmental factors also play a role in how often you should repaint, since harsh climates can be hard on a home. As a general rule of thumb, homeowners should repaint their home every six to ten years.
While vinyl siding salespeople claim it never needs to be painted, it does lose its color strength over time, and the degree of fading can vary depending on which sides get the most exposure to sunlight. Perhaps it still hasn’t faded, but you don’t like the color much. You can’t go any darker than its current color, though, because the siding is designed to absorb only so much heat, and a darker color could cause it to buckle. Vinyl paint is available in many colors. Brush painting and roll painting vinyl siding costs $43 per 100 sq. ft., and spray painting costs $34 per 100 sq. ft.
Although interior house paints can be purchased in pint-size samples or five-gallon buckets, the standard measurement is by the gallon can. A gallon can of basic water-based paint can be found on store shelves for less than $25, but the additional cost of a primer coat should be considered. One-coat paint/primer blends for most DIY projects should cost between $30 and $60 a gallon, including customized tinting. VOC levels should be lower as well. For high-end painting projects featuring designer colors or full-gloss finishes, expect to pay $60 or more per gallon.

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. 
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.

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. 
For trim and doors, start with 1 gallon (3.8 L) of trim paint for every 600 sq feet of floor space. Purchase more at the store if/when needed. Trim is something that is difficult to calculate exactly, and it is more time-efficient to simply start with less than you need, and go buy more after you have used up the first round of paint and determined how much you will need to finish by seeing how much you have painted so far, compared to the gallons used.
I had Renato pain both interior and exterior (ongoing as I type). So far these projects have gone about as well as we could've hoped. Renato is great he is very good at staying on top of things and his crews are polite, work quickly and keep things cleaned up on a daily basis. I would highly recommend General Painting to anyone, including family and friends (which we've already done by the way). Thanks Renato.
You’ll spend between $500 and $3,000 or $1 to $3.50 per square foot to paint concrete. However, expect to pay $2 to $7 per square foot since concrete almost always needs a coat of primer first. Double that price if the concrete requires stripping. Concrete is porous. Sealing it not only helps blend foundations and walls with your home’s aesthetic, but also seals it against water. Repairing or resurfacing concrete costs $300 to $500 for every 100 square feet.
