We talk alot about our furnaces & air conditioning needs regular maintenance, but we don't often talk about our driveways and walkways. But they are important to maintain too.
Inspect the pavement for cracks and holes, and remedy them. This goes a long way in preventing accidental slips, trips, and falls. It also works to avoid larger repairs or resurfacing in the future.
If you see weeds popping up between cracks in the pavement, resist the urge to pull them up. You'll remove the upper part of the weed, but the root system will remain intact and new growth will return within a few weeks. For a cost-effective solution, boil water in a kettle, carefully carry the kettle outside, and pour the water on any weeds to kill them off for the season.
That's a pretty cost effective solution for a great walk to your front door!
