J & J Restoration and Construction is a Black-owned, veteran-owned San Diego water damage restoration firm at 5839 Mission Gorge Road, Suite E, in Grantville's 92120 commercial corridor between the I-8 freeway and Mission Trails Regional Park. The company responds to residential and commercial water damage events — burst supply lines, sewage backups, appliance failures, and storm flooding — with extraction, structural drying, and full reconstruction under a single contract. Post-remediation reconstruction covers drywall replacement, texture matching, baseboard and trim reinstallation, and interior painting, with color-matched wall finishing on insurance-claim scopes coordinated through NORDBY PAINTING in College Area. The restoration workflow begins with moisture mapping using infrared thermal imaging and pin-type moisture meters to identify water migration behind walls, under flooring, and into ceiling cavities. Industrial air movers, LGR (low-grain refrigerant) dehumidifiers, and negative-air scrubbers run continuously during the drying phase, with psychrometric readings logged to document progress for insurance adjusters. Mission Gorge Road runs the full length of Grantville's commercial spine, and the 5839 address places J & J within the auto and trade-services cluster extending from Fairmount Avenue north toward SDSU Transit Center. Sewage-category losses require antimicrobial treatment of structural framing and subfloor materials before rebuild, and the company's technicians follow IICRC S500 water damage standards and S520 mold remediation guidelines for containment, removal, and clearance testing. Plumbing supply sourcing for rebuild phases routes through nearby distributors, and Ferguson Plumbing Supply in Grantville stocks PEX, copper, and PVC fittings for residential re-pipe and fixture replacement on restoration projects. The company bills insurance carriers directly on covered losses, handling photo inventories, Xactimate line-item estimates, and supplemental scope negotiations that determine the claim payout.
