"Russell was prompt, very polite and helpful. He explained everything and pointed out where my old rowhouse differs from newer codes. (Grandfathered until I want to sell.) There was an upsell on an annual plan, but it will save some 15% on some planned upgrades, so I went with it. Dawn, office support, also was friendly and pleasant to work with. She gave me a follow-up call next morning after my multi-company query through Angie's. My inquiry detailed list of three small repairs did not get other takers, so no real cost comparison, but I feel the price was fair-- $500 for about 2 hours, including the plan and dispatch fee."
