As any other window, and also as a rain-gutter, as the skylight needs to have the debris cleaned out around it before every rainy season.

What should a consumer consider when choosing a skylight manufacturer/contractor?

Most important is what other people have to say about them. The history of complaints with the license board is important. How well they pay their employees is of great importance, as happy workers provide superior work. The quality and diversity of work that you can be presented with in terms of past jobs is also of great importance. The length of time they can truly document as having been in business says a lot as well, as it takes a good and honest contractor to weather the storms time presents.

If references are important, how do I find references other than what the skylight fabricator/contractor provides me with, as they will likely only provide references they know will say good things.

Look at references provided at Internet sites, such as and These are references that are out of the contractor’s control, and can be good or bad.

How important is price when choosing a skylight fabricator/contractor?

A low price is suspect as it indicates the contractor pays low wages to his men, or is so new to the field that they don’t know how to price a job. A high price usually indicates just the opposite. The price in the middle can mean either thing. It is difficult to choose based on price alone, but you are taking a great risk to hire the cheap guy, because if the skylights leak and the cheap guy is no longer around to service his work, the damage and repairs to them are usually more than what you would have paid the most expensive guy at the outset.

Is there anything else that a consumer can do to protect themselves against an unscrupulous skylight fabricator/contractor?

Though it is rare, I have been asked on several occasions by a potential client to allow them to come to my shop and inspect it to see how clean and organized it is. This goes back to a time before telephones when someone couldn’t just call a reference and inquire about what kind of work a tradesman did, and it was how people would choose one tradesman over another. They would inspect his wagon and his tools, to see how clean and well organized he kept it, if the tools were oiled and sharpened, and make their choice on what they saw.
