I met with Lauren Holbrook who gave me the run down of everything with the windows. Although I didn’t purchase anything due to my budget, she was great, thoroughly explained things to me, and the differences between the windows Offered. In addition, Lauren understood my situation and didn’t try and force me to buy something, which I appreciated.

i just signed a contract to have siding and windows installed in my house. Lauren Holbrook was fantastic. She answered all of our questions, was very flexible with meeting times. She graciously accomodated my last minute request to meet at a different location to sign and go over the contract. Lauren is very professional, patient, lovely to work with. She has set the bar very high for the rest of the staff. I look forward to working with the rest of the Coastal team.
