Safety King came through for us big time! We were a bit skeptical of the idea but the results are as clear as the air we’re breathing now! Vern and Devan were very polite and very kind to us: they ever tied up several little loose ends, that we had not considered, without heaping extra fees or surprises on us. I didn’t realize all the ins and outs of the duct cleaning but Vern had several alternative solutions ready: he definitely know what he’s doing! Very considerate! They left no trace when they left and no trace of the previous owners either (nicotine and dog hair like you wouldn’t believe! Now it’s all fresh air). Would recommend for sure. It’s an expense well worth it for any home buyers who don’t want any surprise allergies. Customer service was great! We got stood up twice previously by another company but Safety King kept their word!
