“I was recommended a different company at first, and I called them and sent photographs. Their technical person said it was too far gone. I found Matvey and gave it a shot. They made an appointment and were timely. They could do the job. I was very pleased. The highly recommended. company couldn't do the job but Matvey could.”

“I am very happy with them. They came when they said they would. They were very quick and efficient. They raised the deck. They left the landscaping in good condition. Before they came out, they had a locator come out to find out where the water lines were so that they would not dig into them. Lastly, their price was in line with the other estimate I got.”

“They all expertly performed and provided good communication with the customer for any alternative options. When they came to do this or that, they were careful to get my input. There was a delightful exchange with the fellow who came out to access it in the first place and the fellow who came out to do the work.”

“Matvey Construction came out when they said they would. One person did a survey and an estimate. The installers completed the work, very much to my satisfaction. They all did a great job. It was a very positive experience.”
