"Absolutely miraculous job! They turned our wet nightmare dungeon into a perfectly dry basement! Highest recommendation! We got floor drains, sheeting over our stone foundation, a sump pump and floor drain at basement door. Work was fast, professionally and was exactly what the basement needed."

"NTK did an outstanding job building a stone and wood bridge across a stream in my yard. It looks very natural, fitting in perfectly. Last year NTK installed french drains to draw water away from the house. They're a great company to work with and capable of most any kind of earth or stone work."

"Tom from Metcalf plumbing did a great job. First, he came out on a Sunday morning to fix an ongoing leak . He immediately knew what the issue was, had the part and finished the job under an hour. He also made adjustments to our water pressure settings to prevent problems in the future. Tom was professional and pleasant. I would definitely contact him again."
