Preston communicated quickly and clearly via both email and phone. He and his crew cleaned our new home to get it move-in ready and we were thrilled with the results. Preston also offered to come back if anything wasn't up to our standards at no additional cost. We will definitely be using Knepp Cleaning again and recommend their services to our friends and family.

We asked Knepp Environmental Services to clean our carpets, and my favorite recliner, while we were away on vacation. They did a fantastic job! Everything was extremely clean and smelled wonderful. The carpet, and my recliner, look brand new. I highly recommend them to my family and friends. You will not be disappointed. I promise!

I would highly recommend Knepp's Environmental Services. Preston cleaned our carpets in August and did a fantastic job! He showed up when he was supposed to and was very efficient. He cleaned all the carpets that were requested plus an additional thick rug. He was very professional but also personable and my carpets look great! Now a day I feel like it is hard to find a company that genuinely cares about their work and this company most definitely does! Highly recommend!

We fully endorse this company. We were curious to see how their system worked. We knew that they owned one of the highest quality truck mount machines around (The butler system) Preston came out and met us at a residential home so we could inspect and review his methods and equipment. We were very happy with the results. The level of quality his machine operates at was very impressive and out performed anything we have ever seen.

His timing was very good. Carpets looked brand new afterwards and they were surprisingly dry. The chemicals he used were extremely environmentally/pet friendly. He was very thorough and inspected every inch of the carpet making sure it was 100% clean. We strongly recommend this company for the the state college area and surrounding areas.

I thought that all carpet cleaners were the same, but not so! Preston recently cleaned our carpets and I can hardly get over how wonderful they look! It's almost like getting new carpet again - a real step up from the last company who cleaned them. I would highly recommend this service - look no further!
