Ask these questions so you know how you will be billed and the expected payment due dates.
Why you should ask these questions? All of this information should be included in both your bid and on the contract you sign. Check these details carefully, then compare to other bids you obtain. (Get at least 3 bids, all in writing.) Be wary of any really low bids. If the contractor can’t supply the information, ask why not. After checking any contract to be sure this information is included, have a contract expert or lawyer review the contract before signing it.
Ask these questions to find specific details on what the contractor is proposing and why, as well as general information on what you can expect during and after installation.
Ask these questions to be sure the contractor knows the business thoroughly and has satisfied other customers. Also, be sure to request copies of insurance documents, certifications and licenses, so you know that the contractor and installers have gone through required training. Be sure to call former customers and check out other installations the contractor has completed. You should query local Better Business Bureaus and your state Attorney General’s office, and check online rating services for comments about the contractor and the equipment you plan to purchase.
