I fully understand that it happens on Saturday- Family, BBQ and so on, but if you posted your working hours 9-1pm cancel anything but not your customer!

I saw this business on Angies list. I sent in a description of a couple small projects and was sent…read morea message to call and make an appointment for an estimate. Fair enough. I called and spoke to a young man that agreed the projects I inquired about is what they do. He stated that his manager was out of the office and she would call me with in one hour. No call for the entire day. The next day I called and received a recording. I left a message stating that I had called the day before and I wanted the estimate. I waited one week being generous with the time and still no return call. Not even to say we might be too busy, we don't give a damn, nothing. So if you choose to use them, have your back up numbers ready. There is a good chance they just don't have the manpower to do the work. I find their customer service to be in the worst form.

As with other reviewers Irdwin was Johnny on the spot at first. He did half of the contracted job…read morethen told me his saw was broken, he would get it fixed and be back. That was two weeks ago. I called, texted etc. No response. I had to rip out the shower pan area he did and hire another tile setter to do the job because there were dips and the slope was wrong. I don't know what Irdwin's priorities are but it's not his clients or being reliable. I lost money in this job and haven't left. I will not leave as I continue to lose money. I will finish the job, take the loss and move on. That's what a professional does.

At first everything seemed great, Irdwin was responsive and extremely professional…read more He came by quickly for a quote on installing a new bathroom shower door and installing kitchen vents. The estimate was very reasonable, but being a new contractor I hadn't used, I wanted to see the quality of work before giving him the bigger vent job. So I asked that we just do the shower door for now. We paid the job in full on dec 4th, and it's the 16th and still no door. We're probably put on the back burner since the job doesn't have a high dollar amount. Happy to update my review if he ever shows up. -----updated dec 27th---- Still no show nor a refund. Will have to go through BOA to get our money back. Don't recommend.

He completed the job, we paid, and he said that if there were any issues to give him a call. On February 11, we reached out and let him know that the photocell was not working again and he said he'd check to see when he was available to come by again. We did not receive a response. On March 27, I reached out to him again asking when he could come by to replace/look at the photocell work he had completed. He responded March 31 and said he would come by on the weekend to fix it. He never came. I understand he has another job now, but we have been waiting for him to return to look at the light for some time. Although very nice and respectful, I would recommend that others go elsewhere -- he just did not follow through with coming back to fix our issue and we have to look for help somewhere else.
