Pella Thermastar Windows

The Pella ThermaStar window is the company’s low end vinyl window that is sold almost exclusively through big box stores like Home Depot and Lowes. In fact, the window is no longer even listed on the Pella website. However, it is still included on the Consumer Reports window ratings list, where it received the lowest score of any of the vinyl window models and series.

Many contractors and installers feel that the window feels relatively flimsy and in general uses low end components and hardware. In the past, there have also been issues with Pella’s quality control in terms of their vinyl windows; one batch of windows would be fine, while the next would have seal, sash and weatherstripping problems down the road. Our recommendation would be to opt for something other than the ThermoStar – Reliabilt windows are often sold at the big box stores and are a better alternative to the ThermaStar.

An option within the Pella family might be the Pella 350 Series, which has received much more favorable reviews from installers and contractors and may be worth a look if the price is right and the installer doing the work has a good reputation.

We would encourage consumers to get several bids from local companies in order to get a good feeling for what’s out there in terms of overall quality and to learn more about your particular installation requirements.
