Liz Vogt

Bathroom & Plumbing Client

★★★★★

“Colin Allan and his crew did a great job of repairing and remodeling our two bathrooms, as well as fixes to the piping and flooring. He always answered phone calls and messages and showed up on time. He is by far the best contractor with whom we’ve worked. In an era when you can’t get contractors to show up, he’s a pleasant surprise.”
