I have Allied's siding on my house. They did my siding, and I liked it well enough that I called them back and had them replace the stucco areas with HardiePlank. I don't remember a whole lot about the first siding workers because that's been a number of years, but the ones who came out to do the stucco replacement were very nice and cleaned up after themselves, and they came out when they were supposed to and finished the job promptly. So, I'd say I was very satisfied. I'd give them an A.

It was a good experience because they pretty well explained the different steps that were going to take place and everything with the siding replacement. The engineer came out the first day. First we had to put plywood on the house to bring it up to code, and they're pretty well organized—cleaned up every night, and let me know, almost teaching me, what they were going to do the next day and kept me up to date. We tore off the old cedar siding we'd had on the house for over 25 years—it was messed up and dried up, cracked up, and pretty well getting to be a fire hazard. So, my daughter had HardiePlank on her house when she had her house built, and it held up through Ike and the hailstorm we had this year, so we decided to go ahead and get the old cedar off and put the new Hardie on. Allied Siding & Windows did a great job. I'd give them an A.
