Phelps Construction & Restoration | Damage Restoration & General Contractor in Chehalis, WA

The earliest signs include a sudden spike in your water bill, warm spots on the floor near the heater, a musty odor, or discoloration on walls and baseboards. You might also hear a faint dripping sound even when no faucets are running. In Chehalis’s damp climate, these can be easy to overlook. If you notice any of these, contact Phelps Construction & Restoration immediately—while you locate and shut off the heater. We’ll assess the damage, extract standing water, dry the area thoroughly, and handle any necessary abatement if mold has started to grow.

Sewage backup is a Class 3 biohazard that requires urgent, professional attention. We first establish containment to prevent cross-contamination, then safely remove all affected materials—including drywall, flooring, and insulation. We disinfect the area using EPA-approved agents and perform environmental abatement if needed. After structural drying, we reconstruct the space to its pre-loss condition. In Chehalis, backups can happen after heavy rains overwhelm the city’s system or due to blockages in aging lateral lines. Our team works quickly to restore your home while keeping your family safe from pathogens.

The best solution starts with an interior assessment by our certified team. Groundwater intrusion often results from hydrostatic pressure pushing water through slab cracks or wall joints—common in Chehalis’s high-water-table areas near the Newaukum River. We implement a combination of interior drainage systems (e.g., French drains or sump pumps), crack injection, and vapor barriers. If contamination is present, we perform environmental abatement. For lasting results, we also address exterior grading and gutters. After mitigation, we can finish your basement with moisture-resistant materials to prevent future damage.
