"We had our basement waterproofed by Baker's. It's been bone-dry since. We did have one piece of equipment fail within a month of the installation, but it was a third party dehumidifier that was just a dud I guess, no fault of Baker's. I texted the project manager about it on a Sunday. I expected a response the following week. He got back to me within the hour. The equipment was removed and replaced within a couple days. Everything great since. I would highly recommend Baker's, but specifically our project manager Nathan Goddard and the head guy on site Daylan. Can't remember his last name, but he's got a long beard and did a great job. Thanks to both of them and the rest of the guys."

"G&J was referred to me by another contractor I had doing my windows. My basement walls were very bad caving in. They came out and got on the job quick. The crew was great, so clean and professional and so knowledgeable. The owner came out also every day to check on my job since I was nervous about having a new foundation put in. He put my mind at ease. The girl on the phone Katie called me every day to go over the process. They really were great all around."
