Based on 23 verified paid-installation prices from 4 different Iowa-credentialed contractors serving the Des Moines metro (2016-06 through 2025-01), the median price was $1,095, with a range of $900–$2,800. This is drawn from customer-reported prices on Angi and HomeAdvisor, not contractor-advertised “starting at” quotes, and is only published because it clears our own bar of 5+ prices from 3+ contractors — most Iowa metros don't clear that bar yet and we don't publish a number for those. These are metro-wide prices: reviewers didn't say which city their job was in, so none is confirmed as a Hartford job. What changes the price →
