Owner
I recently purchased a house that had a hot water furnace installed by Paul Robben in 1995. The welded copper pipe fittings for the heating system are now leaking in three different areas (perhaps more) inside the walls throughout the house. I called Mr. Robben and had him inspect the leaks. He confirmed that he had indeed done the work and said that he would "look into why this was happening" and get back to me. I never heard from him again.
I had my general contractor reach out to try and get some accountability and answers from Mr. Robben, but he refused to agree to repair the inferior welds, saying that his work was only waranteed for ONE YEAR. He did agree, however, to charge me more money to install pex pipe in place of the copper pipe he had installed just 16 years before. I have declined this offer because I would never knowingly allow this person in my house again.
I'm not an HVAC expert, but I have since learned that copper pipes and fittings are supposed to last for DECADES and CENTURIES, not 16 years. When I had a second HVAC company inspect and repair the leaking welds, the repairman stated that the original installer "did not know what he was doing". The welds were uneven and of poor quality. There were flakes and chips everywhere. It looked as though the welding material was not heated properly, and because of this, the welds didn't last.
I'm writing this review in hopes that others will learn from my experience. Robben and Sons do NOT stand behind their work. They will NOT rectify problems that they knowingly have caused. They will attempt to "DOUBLE-DIP" people for work that they have already been paid to do.
If I had actually paid Robben and Sons for this faulty installation, I would be filing complaints with the Oregon State Contractor's Board and the Better Business Bureau (there have been others that have done this--check it out). I would also be filing a lawsuit against this company for substandard workmanship. But because I inherited this problem from the previous homeowner, all I can do now is warn other potential customers about the DISREPUTABLE BUSINESS PRACTICES of Robben and Sons.
WATCH OUT!
