There are “low-cost window companies” out there that use poor sealants and flawed installation methods. This is something the homeowner won’t see until their windows need replacing prematurely. Other window companies install windows in less than 30 minutes…they also use low-cost sealants and caulk products to save money. This type of installation can lead to costly future problems, expensive repairs, and decreased energy efficiency. So while you think you’re saving money by using the cheapest contractor, you’re only setting yourself up for expensive future problems!
