"Terrific, we decided to go w/ Stoneberger because their sales representative spent time advising and guiding us through the options, the colors and styles of doors. She listened to what we thought we wanted and helped us find the right solution. No other sales rep we met with offered that customer service. She also followed up on time and was super easy to work with once we decided on specific doors. Installation also was on time, efficient and went very smoothly. We had one issue that arose b/c of the age of our house and Stoneberger addressed it quickly and beyond fairly. Highly recommend them."

"Very well -- installed antenna and hooked up all three TV's. No hassles, fast, friendly, effective, and relatively attractive system. It was money well-spent. It meant I didn't have to walk around on the roof trying to guess where was the best place to position the antenna and then point it in the best direction."

"Scott came to the house and measured the door/windows, provided a rendering of the door/windows and the cost. I had to get HOA approval and once that was done, an order was placed. As soon as the order came in, a date was scheduled for installation. The crew showed up as scheduled and installed the door/windows. They are beautiful!"

"We booked 3 hours with a 3 person crew to unload our 16 ft POD storage unit at our new house. The three men who showed up were incredible! They were on-time, courteous, and fast. They unloaded the POD in about 75 minutes, often carrying two 40 lb book boxes at a time. If they had one hand free, they would pick something else up with it. They did not take breaks, but moved quickly and deliberately. They handled our things very gently. I would use this company again without hesitation. Their service was absolutely excellent!

"MaryAnn O'Hara is the quintessential professional:  She arrives exactly when she says she will; she knows her business and what her services and products can and cannot accomplish; she gives prompt, exact estimates; and she ensures that her staff provides exactly what is promised.  And, she's a delight to work with. 

The refinishing process has a very strong chemical smell that quickly spreads throughout the house.  The refinisher did everything he could to mitigate dust and smell, but it was difficult to control it all.  The first day it was very unpleasant; the second day, we opened all the windows while he was working and turned up our air conditioner fan to high, which dissipated the odor fairly effectively.  By the next day, the odor was gone completely. 

It was well worth the temporary odor.  The room is literally transformed.  We are very pleased and are already planning to do the same to our other bathroom this fall. "
