i love using certified. I always get residents who would rather trust someone who works in the field, than a manager who doesn't work with growth. You guys are always so willing to come out and explain to the residents what's causing the growth. Very nice to work with as well! You guys are usually the first to call in terms of vendors

We are extremely pleased with the work done. The technicians were great! They worked nonstop, in rain that alternated between drizzle & pouring AND it was very windy. They were courteous & professional, did an excellent job, and an excellent clean up before they left. Great work! Amazing looking results! Not ten stars..more like 20 stars!! Thanks!

Certified was great. They remedied the mold problem and fixed a detatched vent that was non-functional. They let themselves in via lockbox and accepted payment via escrow closing and sent comprehensive follow up photos to show all the results. Everything was totally professional and made getting this issue addressed very easy.

They were careful throughout the house with ladders and tools. When they left there no more mold. Plywood was clean as a whistle. I give them 5 stars ⭐️ ⭐️⭐️⭐️⭐️
