Wood or Fiber Cement Siding Installation or Complete Replacement
$6,000
We had our front entry door, side lights and storm door replaced in 2020. The guys did a great job. We have had some settling and Z Double B came right away to make adjustments.

11-18-2020 Dear Yelp, This compliant is in reference to Z double B located at 12860 W Cedar Dr Ste 110B Lakewood, CO 80228-1965. Phone number 303-997-8168. The owner is Zach Baumann. I WOULD NEVER USE THIS COMPANY FOR ANYTHING! I first paid Z Double B in September 25, 2019, to purchase a folding door to be install at my house and signed a contract at the same time. In the contract it was stated that the door would install in approximately 12 weeks. The door was installed in mid-march 2020. Once install I notice Z double B order the wrong door! When I ordered the door I showed the sales person the door I wanted at my neighborâ s house. I called Zach Baumann the owner of Z Double B and explained that the wrong door was order and his response was â you didnâ t say you wanted a flag door and you signed the contract.â Flag door is a term I have never heard. I explained that I showed the sales person the exact door I wanted, I also explained that no one from his company went over the final design of the door or the contract which I signed. The project manager, Robert, explained to me that the sales person did not have much experience in the type of door. I paid for half of the door in September in 2019 14500.00 and the job has not been completed as of mid-june 2020. Nor has the trim been matched as discussed. The new door to fix the issue has also NOT been ordered as of mid-june 2020 even though Zach knew they ordered the wrong door in mid-march 2020. I have email and texted Zach Baumann many time stating that I would paid in full once the job is complete which will not be complete until at least 7/31/2020, which would mean the job took over 10 months to complete. Zach is calling everything a change order when it is not, I originally I asked for a door a certain way and the trim. Z Double B has not finished the job as of mid-june. Zach is asking me to pay for the rest of the balance 14500.00 even though the job is not complete. Zach has threating to put I lien on my house even after I have put in writing that I will pay the full balance once the job is complete. Zachâ s commutations has been terrible. He does not answer text, emails or phone calls. My door finally got installed on 9-3-2020. Then in November I notice that the new door was not installed correctly. As of 11/17/2020 I am still missing a pin in the door. I WOULD NEVER USE THE COMPANY FOR ANTHING! From start to finish my project took 12 and half MONTHS! If you would like to discuss this please call my cell at 773-426-6636 Sincerely, David Diaz
