Raymond was very good about providing an accurate estimate. We contacted him the first time, and got an estimate. We delayed construction for a year, and then asked him for another estimate. The estimate was very timely and very fair. The demolition phase (removing the siding) went very well. Since we have a 2 story home, Raymond had a roofer come first to carefully pull up our roofing tiles so that they would not get damaged wen the siders were standing on the roof. The roofing guy was VERY careful and very nice! I had a couple of special requests ... that I could install some wiring for security cameras and for relocation of a cable TV plug. Also, we wanted some electrical work done: adding 3 new motion sensor lights, and some work on existing plugs. The electrician that Raymond subbed the work out to was EXCELLENT! Not only was he personable, but he was VERY careful with his work (i.e., not to damage existing work), and very thorough. Now to the siding: When the workers put up the Tyvek on the house, it was done sort of piecemeal. I would have expected contiguous unrolling of the material, but they put it up in chunks, with the Tyvek put up in weird angles, and sometimes overlapping the wrong way (i.e., lower piece over the higher piece). The did fix it all, after I brought it to their attention. It was difficult to communicate with the installation crew, as most of them didn't speak English, however the foreman was very nice and was able to get my wishes across. As far as installation of the HardiePlank siding: Even though I am retired, and was on-site a lot to watch the construction, a lot of the time I wasn't present. One of the KEY points when I wasn't present is when they started. My neighbor dropped by to watch them and noticed that they weren't lining up the boards at the first corner they started on. He brought it to their "attention" that they should line up the boards! Which they did ... but that's something THEY SHOULD HAVE KNOWN. Also, in a number of places, they left the ends of the planks "hang" between the studs, where they should have CUT the planks AT the stud, so they would be secure. I brought this to their attention, but was NEVER resolved, and we still have some planks where the end was NOT secured. This might have been due to the language issue with the installers. There was some dry rot problems that were to be fixed. All of them were fixed fine. However, there was a dry-rot hole in the roof that was uncovered by the roofer, which was left open (since we're in CA, that's not really a problem). BUT, it was uncovered through a few rain storms, and water seeped into the attic. We had requested that the hole be covered, but nothing was ever done. I finally went out MYSELF and put some tiles over it ... it only took me a couple of minutes, but it was something that I should not of HAD to do myself. Next: I had done my research when selecting HardiePlank, and there were specific installation instructions with respect to how to frame around things sticking out through the walls (i.e., hose bibs, electrical plugs, vents, etc.) I had it in the contract to follow the HardiePlank installation guidelines. Now, the installers DID follow the instructions (pretty much to the letter), but the job they did was HORRIBLE. They stuck small cut-outs every which way around the protrusions, some with grain going up/down, some with grain going left/right, most of them not flush with each other ... it looked like a pre-schooler "pasted it on". I brought this to Raymonds attention. To his credit, he correctly stated that he told me we should do it a different way, and I had argued to do it the way Hardie specified to do it. However, we got into an argument as to bad it looked, and he fell into the "well that's the way it's specified" mode, which was VERY annoying. I asked him if that's the way he would want it on HIS home, but he still fought back with "that's the way it's specified". We finally got past that, and he did re-do the problem areas ... but it was a very annoying exchange. Along with the excellent electrician, Raymond had contracted to another "native english speaker" to do the detail work. This guy was also EXCELLENT! His attention to quality and detail was superb, and was very easy to interact with. He did all the detailed work that was left by the non-english speaking installers, and did it well! The final phase were the painting subcontractors. They did a FANTASTIC job! They had the calking done in very short order, and were in and out very quickly. They came back a couple of times, without prompting from me, to make sure every last painting detail was perfect! I was very impressed by them. As far as my ratings: If I had to rate just the siding installers, I'd rate them as FAIR to BAD. However, the Electrician, the detail guy, and the painters I'd rate as EXCELLENT. I hope this review helps!
