We visit the Billerica Fire Dept. to hear what it was like to fight the Silva fire, and how it might have been prevented or at least kept more manageable. Back at the house, our host meets with the Silvas' insurance agent, who explains the benefits of having a ""guaranteed replacement cost"" endorsement on one's homeowner's policy - it provides for rebuilding after a complete loss. Public insurance adjuster (and former This Old House homeowner) Dick Benedetti shows us some of the process by which he is writing up the insurance claim for the Silvas. Architect Chris Dallmus begins to discuss the design of the new structure with homeowners Dick and Sandra Silva, while outside a perc test is run for the new septic system and lanscape contractor Roger Cook takes an inventory of the plants that did and did not survive the fire.
