(1) It is a good idea to ask the window replacement company to give you a list of at least 3 or 4 recent jobs that they have done so you can go see first-hand what the finished job looks like.

(2) When comparing proposals from various contractors, make sure the offerings (scope of work) are the same (an apples to apples comparison).

(3) Be sure that quotes are “inclusive of the total project costs. Some companies may provide quotes that do not include aspects that are required in order to complete the project.

(4) Get all guarantees, warranties and promises in writing.

(5) Only contract with contractors that have all of the proper insurance (workers compensation and general liability). Request written proof and call their insurance company to verify the validity.

(6) Communication is key to success on any contracting project and the more examples of previous work (jobs) a contractor can relate to your job, the better indicator of quality of that contractor.

(7) Always hire companies that you can communicate with and have a permanent office address. You want an established company with an office you can go to if you ever need personal contact. Check out the address and how long they have been in the area.

(8) Pay contractors by check or credit card. Avoid on the spot cash payments. In fact, avoid all cash payments, as there is no paper trail of payment to protect you. If a representative of a company or even a manger of a company requests any form of cash payment, this should be a major “red flag” of caution to you as a consumer.
