Barry Cohen2024-05-14Andrey and his team repaired a fence for me recently and I could not be happier with the work. I know he went out of his way to keep on schedule to do that work on the day upon which we agreed even though it was inconvenient for him. The team arrived on time, did the work efficiently and I believe for a reasonable price. The end product, the repair, was excellent. I would use this company again.Trustindex verifies that the original source of the review is Google.
