"Angie quoted a price of $199 price was $675 to replace old toilet with new toilet. I needed to get it done but that is a huge difference from what I was expecting to pay. Service was quick fast and the plumber even walked me through some of the features. Install was tricky and he did it with no issues. Everything so far is working perfect."

"Louis was very professional and explained how he would repair my brick walkway and glass window replacement. It came out exactly as I was told. Looks great and I would hire Louis for other projects. I say everything was perfect."

"Steve did a good job. On our house in Falmouth. He dealt with us literally changing the kitchen design mid point of construction while having a good attitude. He helped my wife recommending a shower etc. Steve did everything up to code and pulled the right permits. When we had challenging situations he was creative. Steve dealt with a millworker/contractor who was installing our cabinets and less than professional. Steve was diplomatic working with others. Over the years I have renovated a number of houses and plumbers can be a challenge as they deal with pipes. Steve is above the rest"

"The second time I have used Pacific Stone and Tile in lass than a year and my experience this time was just as fantastic as the first time. very reasonable price and the final product looks better than we had visioned. Sal came out and explained all issues and keep me in the loop with updates as our quartz was backordered. The crew was meticulous with their measurements, making sure no gaps were showing due to sloping floors or crooked walls. They were very thorough with the install. You can tell immediately the pride Sal and his crew take in their work. The installers were as friendly as the owner, they kept the area clean and and were very considerate of me and my family. I plan on using Pacific Stone and Tile every time I need countertops."

"Company did a good job last summer with 3 bay windows, so I called them back when the rest of the windows in the house needed to be replaced. On the initial visit, I told the rep that I wanted the same windows as last year. He quickly found the job order and picked up the details of the window make/model/etc without any need for me to reinvent the order. The company had the opportunity to try to upsell me, as I asked them about replacement of the skylight in the bathroom. Refreshingly, they declined to do so and told me that it would be much better to wait until we needed to get the roof re-done, and to do the window at that time. As before, the first guy clearly explained the process: guy 1 to take the order and measure the windows, later follow-up visit from guy 2 to remeasure all the windows carefully before ordering their construction, and then a couple of months later, a follow-up call from their HQ to schedule the install. He gave me an approximate window for this scheduling call. It was a pretty broad time-frame because there had been an unusually large number of people needing custom windows. As before, everything went off exactly as the rep indicated. The install team showed up within a half-hour of the estimated time, and installed 11 windows without taking a break. They removed every scrap of rubbish, vacuumed thoroughly, and left the place as clean as it was when they arrived."
