"Roland did an excellent job. He explained the things I needed and those that I didn't. He was right on time and finished the job in the time he stated. He was very professional and knew what he was doing. If you are looking for a straight shooter without any of the sales frills (and the larger cost) then Sav-On Insulation should be your choice."

"We put off doing this project for a long time because it was a major renovation and we were worried about making the right decisions.  We were fortunate to find Todd because his combination of experience and professionalism was exactly what we were hoping for.  Todd was great to work with!  He had good ideas, helped guide us to make kitchen design choices, and asked for our input on every aspect of the project. We could not be more pleased with our new kitchen!
The following is a list of everything that was included in the labor estimate:
Prep areas with plastic walls to contain dust as best as possible, move appliances, remove existing cabinets and countertops, take down existing drywall to the studs and down to strapping on ceiling , remove existing floor tiles , install new patio door and window, insulate walls, hang drywall, tape and mud or plaster walls and ceiling, create new openings in wall between kitchen and front room and wall at foot of stairs, prime ceiling and walls, install new cabinets, install new window and door trim,
install new tile floor, install tile backsplash, remove all debris, be on site when inspector comes to sign off on different phases of job.

"Vista has come to our house, especially a particular gentleman. Really knowledgeable, very professional. They do several different things. I have had them out to do estimates on gutters. We have not hired them for anything. To give you an idea, when they've come out I was very happy to open the door and see it was the same guy that has come several times to do several things. I interview several people. Not only did he come, and it's a little confusing to me because it has to do with ventilation and insulation, and excuse my language but there is a whole freaking science to this thing, but the owner actually came out. Not only did they keep in communication by computer, the owner actually came out and reinforced the whole education and what needs to be done. I was really thrilled with that. I thought that was beyond the call of duty. I am sorry I was not able to go with them, but I would certainly say as far as customer service relationship, excellent. The information was excellent. Not bothered by the fact that he had to come out more than one time for the same kind of information. I've never had the opportunity to hire them. But I've never been disappointed. They will take the time, they will talk to you, they will educate you, and they will actually give you the best price they can possibly give you. I got educated so that when my  husband came home I could explain to him what is going on. I can't rate their work, but as far as their generosity of time and caring, it's off the charts. I don't know about price because this is a whole new area to me. They were amazing. I have to tell you I have had them out several times as I said, it's Vista Home Improvements so they do several things, but I feel kind of bad that I am yet to hire them. I am trying to think exactly where Vista is out of, but for the owner to com about to your house. We're talking about a wrap around attic. We are talking about getting on your hands and knees and crawling around."

"Excellent. Brian the general contractor made the entire process fairly painless. While expensive, you get a real contract that is extremely detailed, lighting plans, full cabinet layout/design including moulding profile design, etc. Most impressive is the up front schedule with a detailed plan of what work is planned each day (including who is arriving to do the work). This made it very easy to plan. The project took just a bit over 2 months from start to finish. The quality of the work was exceptional - the carpentry was perfect, the tiling was extremely even (which is saying something due to the diagonal layout and the large number of cuts needed). When they installed the stove (very heavy Wolf) they used air-cushioned floater boards to move this 500+ pound stove over the tile without any fear of damage. Given the horror stories of contractors who show up 1 day a week, you never know exactly what is going on, and taking far longer than promised to complete the job - Kitchen Center was a dream to work with. Highly recommended."

"Excellent. Don was the best contractor we interviewed and worked with in 25 years of home projects in New England. He was professional, personable, very easy to work with. He communicates very well and clearly what he plans to do, updates along the way, if any issue arise, and gives very helpful and skilled recommendations for solving issues or improving design. Quality of work was exceptional. Very detailed for finish work. He also works very fast and efficiently. He was on time or ahead of schedule for most of the projects. He was on or under budget as well for two large projects which was very impressive. I absolutely will choose Handyman911 first for my next project."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"It took a month to come out, but he answered all of the questions that we had. His prices were reasonable. He did it nickel and dimes. He was very responsive. When we had a problem he would come out right away or he would send somebody that in authority that work form because he has like a general form and that kind of handle some of the jobs. A lot of crews are foreign born and English is not their first language, but he always made sure that he had one person on the crew that spoke good English and he made sure that we were introduced to each other then we could go to them.  On our roofing, it was $16,750 I guess for the price and then on the windows it was $27,700 and they were the same windows that Simon Brothers had proposed, same brand of windows so we were comparing apples to apples. We got the roofing done probably in October last fall. It was a different crew that did the windows. The windows we finalized everything in October. There was just a lot of little details about how you're going to handle it, how you're going to handle that. But the windows they started in December and I want to say they finished the last bit of it probably in the beginning of February. There was a lot windows, 29. When there were something that we were questioning or that we weren't too happy about that he would come and resolve the issue right away. He was very responsive, very professional and very personable. My husband is so happy with them that we are going to start a garage addition this fall, and he didn't even ask for a price ahead of time or even considered getting another price. He just said, "We'll call Brian and we'll work out with him how we are going to do this". Plus, on the roofing, they were so neat about it. They were very neat and very respectful of the spaces and everything, but the roofing, they did such a neat clean job cleaning it up. I know it was a little hard because it was snowing on the ground that time, that our neighbors across the street said, "We really like them. Who did your roofing? We're going to call them". It was noticeable how they tried to accommodate us in any way that they could. We were very happy with them. We are going to use them in the future."

"Brad Stearns promptly answered my phone calls, kept me informed on exactly when he woudl be stopping by, and came to give an estimate. While he was there he happily looked at some other parts of the house and gave some advice on other jobs I was considering having done in the future (remodeling an attic, removing the vinyl siding, having the walls insulated). He emailed a detailed estimate and when we accepted his bid, got his crew our within a week. Originally it seemed we would able to replace only the 4x8 beam, but when his crew discovered that the 4x4 sitting on top of it was rotted as well, he contacted me to tell me he thought a laminated beam would be needed, that this would cost around $300 more than the original estimate, and got my permission to proceed. His crew was very experienced, put down a tarp to protect the freshly painted porch, and finished the job on time. Brad stopped by himself to see whether we were satisfied with the job. I certainly plan to call him when the next project or repair comes along."
