Hoerner came to our rental property after I called them about a complaint from one of the tenants that the toilet was making a gurgling sound and not flushing properly. After several attempts to diagnose the problem ourselves, we called in the "big guns". Cole and Nick arrived and after a camera inspection determined that the problem was with tree roots, gravel, and dirt blocking our century old clay pipes. They promptly dug up the concrete floor to get at the problem and discovered broken clay pipes and indeed - tree roots etc. - everywhere. They set about clearing out all the debris and replacing the clay pipes with PVC throughout the basement to the property line. This was an enormous job and the team worked efficiently and were always respectful of the property and the tenant. Cole & Nick were Incredibly thoughtful and always let all the tenants know in advance when the water would be unavailable so that they could plan for it. The tenant said that they even moved snails off the path so they wouldn't harm them during the work. :) - It's the little things. Once this was completed, they realized that there was still water leaking - now from the water pipes, which were still the original (i.e. lead pipes). Andrew sounded almost apologetic when he broke the bad news to me. We would have to replace the lead pipes with copper, adding even more to an already very big plumbing bill - but it needed to be done. They replaced our old pipes with 3/4" copper and backfilled the soil. They tidied up beautifully and closed the giant hole in our basement floor. Throughout this messy project the workers did their best to keep the tenant's apartment clean as they walked in and out of the main floor apartment. The team worked hard and were pleasant and polite throughout the 2 1/2 weeks it took to fix the problems. Hoerner has done several jobs for us in the past at our other rental properties and at our home and I recommend them very highly for their quality work, professionalism, tidiness, courtesy, and respect towards everyone involved.
