"Had a great experience with A Step in Time Maryland, LLC. The owner came out on a weekend to evaluate our fireplace and provided us a fair estimate. He was direct and very comprehensive. The repairmen came out the next week and went above and beyond their duties. They even color-matched the inside of our fireplace! He guaranteed us 25 years to a lifetime warranty on all of our repairs. We thank you for keeping our home safe for years to come."
"A Step In Time Maryland, LLC is the only sweep I’ll ever use. They will inspect and advise on repairs without using pressure. Check around with other sweeps and compare their prices and be sure to understand the materials being used. They inspected mine and advised on repairs...others could not compare to the stainless steel material and their price. You will end up with A Step In Time Maryland, LLC!"
"Met with the owner for the first time yesterday for a chimney liner replacement, and was able to get scheduled right away. Workers came in (on time), did a fast job, and left a really clean space behind. Good people to work with. Would definitely call them again. Thanks!"
