There aren't enough hours in the day to get everything done and wouldn't we all prefer to spend those hours with family and friends rather than Mr. Clean? Even if you can't get out of the house for a weekend adventure, hire a maid service for a Saturday afternoon and escape the mess.
When you hire a cleaning service, whether you intend to use them regularly or as a special treat, the service will ask you a number of questions about your house and habits to put together a cleaning estimate for you.
Be sure to do your homework, too. Are they bonded and insured? What types of cleaning products do they use? Will they supply their own cleaning equipment or use yours? And ask for references -- sometimes word of mouth is the best search tool.
