Do gas logs need cleaning?

“Great service and great quality workmanship.  Have used them for the last 10 years and have always been pleased.  Never been up sold or told that my chimney requires extensive repair.  Utilized another chimney service provider and by the end of the appointment they made me feel that I needed a completely new fireplace after only having the house built for two years.  Valley Chimney has never done that and has always taken care of my fire place.  Would highly recommend.”
