A quality home improvement requires both the right product and the right contractor. Whether it's a new heating system, a natural gas fireplace or another product from PSE's Recommended Energy Professionals (REPs), consider the following points before you decide on a contractor.

Did the contractor:

• Verify adequate venting for natural gas heating and water heating systems or offer direct vent options?
• Discuss equipment and installation warranties?
• Explain the permitting process?
• Explain the maintenance requirements of the system you're purchasing?
• Provide a detailed, written estimate of work to be performed?
• Discuss high-efficiency equipment options?
• Describe exactly what the installation work will involve (e.g., disruptions to everyday activities)?
• Explain the company's service and maintenance ability and hours of operation?

Does the written estimate from the contractor include:

• Disposal of old equipment and other waste created from the project?
• Demolition, rebuilding and painting if appropriate (e.g., for windows or insulation)?
• All permit fees?
• A list of all work to be performed, equipment to be installed and efficiency ratings?
• Warranty length for equipment and labor?
• Service contract?

Remember that proposals from different contractors may look as different as apples and oranges. Don't be shy about asking any contractor to clarify their proposal. Be an informed consumer—bring up lots of questions. Ask each contractor the same questions for consistency.

When remodeling your home

Remodels or extensive roofing projects can take weeks or even months. Choosing the right contractor is essential. Here are some issues to consider for more involved home remodels and roofing projects.

• Don't be afraid to ask questions-write them down so you don't forget. Clearly define the problem you want to solve.
• You may want to hire a designer to create project specifications if you're not comfortable doing them yourself. For example, specifications for a kitchen remodeling project might include cabinets, flooring, sinks, faucets, appliances, countertops, doors, windows and any custom carpentry needs.
• To help communicate what you want, gather photos from publications that illustrate your preferences. Sharing these images will help your service professional get a feel for your tastes.
• If subcontractors are involved, what are their names and license numbers? Do not pay in full until you receive material and workers lien releases.
• Last-minute changes are common in a remodeling project. Always specify in your contract that you and the contractor must approve all changes and additional costs. This also protects you from the contractor making changes without consultation. Make all change orders in writing.
• Is a down payment required? Get this in a percentage and actual amount. Most experts recommend withholding 10 percent of the project cost until after completion, to ensure that the contractor will return to fix problems.
• Before undertaking a major remodeling project, make sure that all necessary permits have been obtained. Your city's building department could force you to tear down any work completed without a permit.
