      Master Seal Windows and Doors: Consumers Beware! I recently had Master Seal back in my home to inspect all 14 windows they sold me 4 years ago. Problems and defects include: Broken Window Locks; Cracked Casings; Broken Window Seals (fogging); and all 7 of my south facing windows are showing signs of external distress (buckling). Beyond the disappointment of having invested $12K(+) in failing windows, Master Seal REFUSES to provide me a repair quote without a down payment on labor costs. Granted the windows are covered under warranty, and I can almost accept having to pay a reasonable labor fee to complete the repairs, but for Master Seal to refuse me a copy of the inspection report, and demand a deposit in order to provide me an “estimate” is absurd. After multiple discussions I can only conclude that they have no interest in resolving this. Poor Construction, Shoddy Craftsmanship, and a completely indifferent Customer Service Department. Not good at all.

      Master Seal, Inc. Response

      As the owner, I appreciate the opportunity to clarify our service process regarding this specific customer's request for a window inspection. Our commitment to transparency and customer satisfaction is paramount and we take it to heart. For inspections requested beyond the two-year post-installation period, we have a nominal service fee of $135. This policy, which was communicated clearly to the customer prior to the visit, helps cover the costs of our team's on-site evaluations. However, we always strive to add value for our customers: if any service work is subsequently undertaken, this fee is deducted from the labor charges, essentially making the inspection complimentary. Once the inspection is completed, the findings are handed over to our estimating department. They meticulously assess the need for parts and labor. It's worth noting that most parts are usually covered under the manufacturer's warranty at no extra charge, providing significant savings to our customers. The service fee predominantly addresses labor costs, only for work needed beyond our comprehensive two-year labor warranty.
