1) You know to clean out the gutters, but make sure the downspouts are clear and drain several feet from your house to prevent foundation damage. Estimated cost: up to $200. “If you can do it, fine, but don’t be a Tim Allen and hurt yourself,” says Kurt Solomon, president of the American Association of Home Inspectors.
2) Hire a pro to tune up your air conditioning system and furnace. “If you don’t,” says Bill Shaw, a contractor in Houston, TX, “you’re wasting electricity and putting more wear and tear on those units.” Estimated cost: $100-$150.
3)Hire a pro to seal your roof. “They’ll catch the insidious things, like the flashing on your vent stacks and the other protrusions on the roof,” says Shaw. Estimated cost: $150-$200 for minor repairs.
Last, consider doing a short, yearly review with a contractor or home inspector who can spot looming problems. In some cases the service is free, or the fee you pay will count toward any work they do.
