Ignorant! I mean we should have known that a company that is established in Norristown would be full of ignorant employees. We understand the gravity on the Covid 19 situation but we called and they said They were open but when we got there we were greeted with an employee that was mean and told us to go away in not so nice words. U just lost very good contractors

Very helpful staff, unfortunately the products are marked up more than double. If I wait 4 days I can buy the same thing online for more than 60% off. Otherwise, great to have a family run business
