"We had our old attic insulation removed and replaced, and the entire experience was excellent. Steve Garrett was our main contact. He was personable, experienced, thorough, and responsive. We appreciated his quick responses to any questions we had. The crew that completed the work was knowledgeable, detailed, hardworking, pleasant to interact with, and worked well as a team. They took pride in doing the job right. Since the installation, we’ve noticed a huge improvement in the warmth of our home, and our furnace is no longer running constantly. We’re very pleased with the results and highly recommend Arc Insulation."

"I wish all the contractors on this basement project were as good to deal with as Family Waterproofing. Throughout the whole process, communication was good. Ken the owner was responsive and patient in answering all my questions and addressing concerns. They prepared a detailed contract of all work to be performed, and did what they said they would. I like that they did an exploratory dig after signing the contract to make sure we had a solid plan and avoid any surprises during installation. There was an area under the basement stairs and an old cistern that required a creative solution. They came up with a solid plan that didn't add extra cost. I asked them to pour some extra concrete under the stairs which wasn't included in the contract, which they did for a good price. The crew was friendly and had a good natured camaraderie on the job. The overall cost was very fair and we received great service and quality. They are honest, care about their customers and want you to be happy. Now I'm looking forward to a big rain!"

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."
