Diamond Rodent Proofing

***** Warning: Stay away from Diamond Rodent Proofing ***** I've rarely felt compelled to write a negative review about a business. But sadly, the level of unprofessionalism and lack of ethics we've experienced with Diamond Rodent Proofing warrants a public warning to anyone looking to hire them for rat or rodent issues. If you're looking for reliable and trustworthy rodent remediation services: Stay away from Diamond Rodent Proofing! See below for recommendations on who to hire instead. In summary: I recommend NEVER using Diamond Rodent Proofing for any pest control needs. They are unprofessional, unreliable, and unethical. Andrew and his team disappeared after taking our money and delivering 0 results. How unprofessional & unethical was Diamond Rodent Proofing? After agreeing to a fee of $2,800 to fully rodent-proof our house and eradicate the rat issue that was plaguing us, Diamond Rodent Proofing not only failed to deliver any results in terms of rodent eradication (= did not catch a single rat) but to add insult to injury, Andrew stopped responding to any communications and became unreachable. Andrew and Ashley decided to completely ghost my repeated attempts to communicate with them via email, phone and text messages asking him for a partial refund given the total absence of results on his part. How did we get here: Like many Oakland Hills residents, we've had to address rat issues sporadically. The process is usually the same: rodent-proof the perimeter of the house/crawlspace, and set traps to catch any rats stuck inside until they're all gone. Rodent remediation companies will typically offer a 2-3 year contract period during which they will come back, reset traps, and check for new entry points. When we started hearing rat activity in the house, we set out to get quotes from various contractors: 1. Honest Rodent Proofing: $13,700 quote >> they suggested pouring a concrete slab in our crawlspace, arguing that we would always have rat issues without a concrete slab. 2. ASAP Rodent Proofing: $2,800 >> Rodent proofing + 3 months of guarantee 3. Diamond Rodent Proofing: $3,000 (2,800 if paid cash) >> Rodent proofing + 3 years of guarantee 4. Rat Patrol: $700 >> Rodent proofing + 2 years of guarantee We decided to hire Diamond Rodent proofing because (1) Andrew was very thorough and professional in his initial inspection (2) he was available to start immediately. We were expecting a baby in just a few months and absolutely needed the house to be clean and rat-free by then. After their initial visit and spending half a day rodent-proofing the perimeter of the house, we continued to hear rat noises. Over 4 weeks, Andrew returned to the house 3 times to further inspect the perimeter - never finding the entry point. Meanwhile, the situation was worsening, and the rats were starting to cause extensive damage to our HVAC system, chewing their way through our heating ducts. We eventually had to resort to hiring another contractor who was finally able to find the entry point that rats were using, seal it and eradicate the rats that had by then completely nested in our subfloor and HVAC system - contaminating half or our heating ducts with urine & rodent droppings to the point that we could smell them in the house. Given the complete lack of results from Diamond Rodent proofing, the fact that we ended up having to hire another company to solve the problem and the massive additional expenses we incurred having to replace our HVAC system - we requested a refund from Andrew & Diamond Rodent Proofing. That's where things became unprofessional and unethical - and why I'm writing this review today.
