Every upgrade at our house was done by Rick Kaitz. We have completely done everything under his care. He treats your home as if it were his own, and doesn't take "good enough" as an approval. We have used him for everything, and will continue to do so.

Outstanding experience - I asked RIck to help with my kitchen remodel after a water intrusion problem. He is the best overall contractor I've worked with. Definitely call Rick if you're looking for great communication, excellent workmanship and follow-thru.
