Browse through home and garden or interior decorating magazines to find a porch in the style you desire. The style and amenities you choose may greatly influence the final cost.
Talk to friends, coworkers and relatives to find out if they know a reputable contractor who does this type of work. Word-of-mouth is one of the best ways to find a trusted individual that does quality work. Check out contractors with the Better Business Bureau. Try to gather at least two or three prospective contractors to compare quotes.
Ask the contractors to visit your home to give you a written estimate of the cost of materials, labor and any permits or inspections necessary in your locale.
Talk to the contractors about the type of wood or other materials they recommend for the job. Some materials do not hold up as well in harsh weather or aren't appropriate for the type of design you have in mind. Well-built porches made from quality materials can last for decades. Inquire about providing adequate water drainage for the porch, recommendations for screening, and the possibility of the porch blocking natural light from your home.
Budget an amount to save for the construction of the porch once you decide on the contractor. Set aside an amount weekly or monthly until you have enough money for the down payment if you are financing the porch, or for the total cost if you are paying in cash.
