They are the best if you are ready to wait 10 days for a quotation and have no understanding of how the system works and what surprise you may find in your lawn.
I had a dehumidifier installed by Crawl Space Ninja in my house about a couple of weeks back. This was after I asked for a quotation for the same, and then asked again, and again, and again, for 10 days. I had read great reviews about them on the internet and went ahead with them. But the follow up to get a quote was starting to be discouraging. Despite all of this, I waited for their quote with a constant follow up. And then I got one. It was not too high but not the lowest either. I wanted to compare them with others in the market. I even did with just a couple others before I stopped. And yes, I received quotations from other within 2 days. But Crawl Space Ninja were just about there with their quotations. So I went ahead and had the system installed.
My fear of work starting with a delay just like the one in getting a quotation nearly came true. The work did not start on the day it was scheduled to. Instead, it started a couple of days later. The work was good and fast though. But once the work was done, the technicians went away faster than they came in. I was not explained about the operation of the system in any way. Now, I have a dehumidifier in my house but I don’t how it works. So if now the dehumidifier develops a problem, I will not know if it is something that can be solved easily or if I did something wrong or if the machine itself is faulty.
