Praise for CALCBS

My Montgomery Village area home, built in 1952, was in need of several improvements. Original to the house were the windows, roof, wall furnace and other (lacking) components. CAL Custom Building Services performed diagnostic testing to determine the condition of my homes systems, and what course of action was best moving towards my goal of improved comfort, energy efficiency and reduced carbon footprint. Their analysis yielded a detailed list of recommendations which we implemented. They included: • Installing a new Energy Star rated cool metal roof • Installing a combined Hydronic air handler heating system which utilized the hot water from my fairly new water heater as the heating source • Installing new low “e” argon gas windows • Installing new attic insulation (after air sealing the attic) • Installing a bath fan in the master bathroom with a time delayed off switch. • Installing a kitchen hood • Re-grading my crawl space, repairing my sump pump and installing a moisture barrier. • Insulating the floor CALCBS created a schedule prior to starting any work, and they completed the job per that schedule. They respected my home, with their crews and vendors never entering without wearing booties, placing down tarps, and always making sure they cleaned up behind themselves daily. I would highly recommend using CALCBS for Energy Upgrade or Renovation work.
