If you’re planning to add an addition to the house, or maybe replace the downspouts before winter sets in, you might want to consider doing it soon.
The price of building materials is starting to rise. Copper (used in those downspouts), aluminum (think siding and windows), and plastic (pipes and insulation) are all getting more costly.
But the price increases don’t mean the US economy is growing at a healthy pace. Instead, the more expensive materials prices reflect higher worldwide commodity prices where demand is stronger. And many of those commodities are paid for with the greenback, which is down 18 percent over the past year.
