Patio design and installation businesses exist to help people turn an idea for an outdoor space into reality. They can compensate for such realities as the architecture of the home and the existing locations of doors and windows as well as hindrances such as outdoor air-conditioning units.
Hiring a patio design firm is similar to hiring anyone for a home-improvement job. The cheapest contractor may not be the best choice for the job. Some questions to ask a professional patio designer before hiring him include the length of time the business has been open and whether the company carries liability insurance. If the design firm is also handling the installation, asking questions beforehand about job completion time and cost per square foot help to avoid surprises during the process.
