The short answer

Stop the Water and Remove Standing Water

First, turn off the main water shutoff valve to stop the flow. If you live in Quincy, keep your shutoff valve location written down for quick access. Then remove as much standing water as you can with a wet/dry vacuum or a pump for deeper water. Work from the farthest point back toward the door to avoid pushing water into other areas.

While you work, wear rubber boots and gloves. Water from a burst pipe may be clean, but it can pick up dirt and debris from floors and walls. Move furniture and rugs out of the way, and place aluminum foil or plastic under furniture legs to prevent stains. Pull up any wet carpet padding and discard it, as it holds water and slows drying.

Increase Airflow and Use Dehumidifiers

After removing the visible water, the real work begins: drying the materials that absorbed moisture. Open all windows and doors in the master suite to create cross-ventilation. Set up box fans to blow across wet surfaces, and point them toward open windows to push humid air outside. If the outdoor air is humid, keep windows closed and rely on dehumidifiers.

Dehumidifiers pull moisture from the air and help dry out walls and floors. Run a portable dehumidifier continuously, emptying the collection tray as needed. For large areas, you may need multiple units. In a climate with cold, snowy winters and coastal storms, drying can take longer, so be patient and monitor progress. If moisture remains after a few days, consider calling the pros for structural drying.

Remove Wet Drywall and Insulation

Water soaks into drywall and insulation, causing them to swell, sag, and grow mold. Cut out sections of wet drywall about 12 inches above the water line to allow air to reach the wall cavity. Remove wet insulation and discard it. Check the wall studs for moisture; if they are wet, they need to dry thoroughly before you close up the wall.

Use a moisture meter to test the dryness of wood framing and other materials. The pros use moisture mapping to find hidden pockets of water in walls and floors. If you see mold growth, stop and consult a mold professional, as handling mold can be hazardous. For extensive damage, local water damage pros often handle the removal and drying process.

Dry Subflooring and Structural Materials

Water can seep into subflooring, especially if it sat for a while. Plywood and OSB subfloors absorb water and can warp or delaminate. To dry them, use fans and dehumidifiers, and consider drilling small holes in the subfloor to allow air circulation. If the subfloor is severely damaged, you may need to replace it.

Structural drying and dehumidification are specialized services that the pros provide. They use high-capacity dehumidifiers and air movers to dry out building materials from the inside out. This process can take days or even weeks, depending on the extent of the water damage. Do not rush the drying; closing up walls too early traps moisture and leads to mold.

Sanitize and Prevent Mold

After drying, clean all surfaces with a disinfectant to remove any bacteria or mold spores. Use a solution of water and mild detergent, or a commercial disinfectant. Pay attention to baseboards, door frames, and other areas where water may have wicked up. Dry everything thoroughly after cleaning.

Mold can start growing within 24 to 48 hours in damp conditions, so act quickly. If you notice a musty smell or see dark spots, that is mold. For large mold infestations, hire a mold professional to assess and remove it safely. To prevent future pipe bursts, insulate exposed pipes in cold areas and keep your home at a consistent temperature, especially in winter. Check your pipes for cracks or leaks regularly.

Frequently asked questions

How long does it take to dry out a master suite after a pipe burst?

Drying time varies with the amount of water, materials, and humidity. With good airflow and dehumidifiers, it can take several days to a week for surfaces to feel dry. Structural drying may take longer. Check moisture levels with a meter to know when it's safe to rebuild.

Should I remove wet drywall myself?

You can remove small sections of wet drywall to help drying, but for large areas or if mold is present, it's safer to hire a professional. The pros have the right equipment to remove and dispose of materials, and they can dry the wall cavity properly. If you do it yourself, wear protective gear.

Will my insurance cover the cost of drying and repairs?

Policies vary, and your insurer decides what is covered. Typically, sudden and accidental water damage from a burst pipe is covered, but check your policy for exclusions. Document the damage with photos and keep receipts for any supplies you buy. Contact your insurance company to file a claim and ask about coverage for drying services.
