Constraction reviews in Golden, Colorado

Ivan is fantastic! Not only is he an expert in radon systems, but he’s also incredibly knowledgeable and helpful when it comes to general home maintenance and equipment. He’s always my first call when I need guidance on anything around the house

Ivan did a fantastic job! Was the most knowledgeable contractor from the 4 I got quotes from. Used the best equipment and routing for our house. Would highly recommend

Ivan and his team were excellent! He provided a thorough estimate for the work to be done, performed the work timely, and effectively mitigated the radon levels in our home. I highly recommend using Martens Radon.

Ivan did a great job and the install was a lot less cookie cutter than other companies were offering. We didn't have a great spot for install but he was able to get creative so that we didn't end up with a nuisance in our finished basement. So far our levels have dropped to below 1 pCi/L
