Stop the water, dry what you can and call us; the consultation is free.
Emergency mold treatment in Falls Church, VA is for the days after water gets into a house, while wet drywall, carpet and framing are still drying. On 9 July 2025 a flash flood warning covered Falls Church, McLean and Vienna and more than 10,000 Dominion Energy customers lost power, and a sump pump without battery backup stops when the power does, so check the pit after any storm that cuts the lights.
A pipe can also give way inside a wall, or a tenant can complain and the landlord need an answer this week. Either way, the steps on this page come first, then a call: tell us what happened, and we'll talk through next steps and the earliest visit we can offer. How we treat is on our mold remediation page.

“Bryce was prompt, polite, and very professional. I'm grateful that Angie's List sent me to Pure Maintenance.”
“Working with Pure Maintenance was a fantastic experience. Bryce was responsive when scheduling the appointment, and he was very informative when explaining the treatment plan and why it would be effective. The technician came at exactly the scheduled time, and the work was completed efficiently. We have already recommended them to our friends!”
“Such great work, an honest company and professional. High recommend their services.”
“Our house needed treatment for some elevated mold levels in a couple areas and my doctor in Potomac, MD recommended EnviroPure. Sean came to the rescue. He was very knowledgeable and reassuring throughout the whole process. Communication was easy and the treatment felt much cleaner and less invasive than other options. We are now in a house that feels like it is breathing a breath of fresh air! Highly recommend!!!”
“Ron and his team are truly caring folks trying to help. Discovering mold and hiring a remediation company could have easily been a costly nightmare. This company offers a completely non-invasive solution, and guidance to prevent any recurrence. The service was affordable and the team went above my beyond my expectations of any contractor.”
“The team was excellent. The work was excellent. Communication was great and the results are fantastic!”
If a pipe burst, shut off the main valve and call a plumber. If rain came in through a basement wall, a door or the roof, note where it entered and how high it rose. If the power went out and the sump pit overflowed, get the pump running again before anything else, and ask the plumber about a battery backup once things settle. If you can't find where the water is coming from, shut off the main valve anyway: if the leak stops, it is in the supply plumbing, and if it keeps going, look at the drains, the roof or the ground outside.
Turn off power to any room where water has reached outlets, cords or appliances, at the breaker if you can reach it from a dry spot, and have an electrician check anything that got wet before it is used again.
Take photos of the water and the damage as you go, and write down the date and time the water came in and when it stopped. Your insurer may ask for both, and the timeline tells us how long materials stayed wet.
Move wet rugs, cushions and cardboard boxes out of the room. Open the space up, run fans and a dehumidifier if you have them, and pull furniture a few inches away from wet walls so air can reach behind it.
Lift a corner of any wet carpet so air reaches the pad, and open closet and cabinet doors in the wet rooms.
Check the rooms around the wet one as well. Water runs under flooring and along the bottom of wall cavities, so the room next door can be wet at the base of the shared wall even when its floor looks dry.
In summer, run the air conditioning if it works and the ducts stayed dry, since it pulls moisture out of the air while the house dries. In winter, keep the heat on so the house doesn't sit cold and damp.
Tearing out wet drywall before anyone has mapped the moisture can add rebuild work you didn't need. Moisture readings show which sections are still wet and which will dry where they are.
If a contractor has already opened some walls, leave the openings as they are and tell us. We can read the framing directly, which tells us how far the water went.
Sagging ceiling drywall is different, because a ceiling full of water can fall. Keep everyone out from under it, and have a contractor take that section down before the visit.
If there's no visible mold but you're worried about what the water left behind, air quality testing through a third-party lab gives you numbers to look at. It also helps when a tenant and a landlord disagree about the damage. Our mold inspection and testing page explains the options.
Sometimes the first sample shows indoor air close to the outdoor one, and that is worth knowing before you pay for treatment. When the numbers are high, the same lab tests again after treatment, so the two results compare directly.
Mold treatment comes after the trades that stop and dry the water. Standing water needs pumping out and drying equipment running as soon as you can arrange it, and a roof that let water in needs closing before the next rain.
Tell each of them about the others, and give every one the timeline and photos you took on the first day.
The water source has to be fixed first, by you or the right trade, because mold comes back wherever moisture keeps arriving. On treatment day the home is empty: people, pets and plants leave, and furniture and electronics generally stay where they are.
The VaPURE sterilant goes in as a vapor and reaches surfaces, wall cavities, HVAC ducting, porous materials and the air. An antimicrobial protectant stage follows, which helps resist new growth once the moisture cause is fixed. Most homes are treated in a single day, and families are back the same evening.
Most homes need no demolition. When a material is too far gone, we say so in the estimate and it comes out. Afterward, air samples go to the same accredited third-party lab, which has no affiliation with EnviroPure.
The consultation and visual inspection are free, and when the inspection confirms visible mold, you get an estimate.
When the whole property is treated and a follow-up lab test within a year shows mold above regional averages, we re-treat at no charge.
EnviroPure is a licensed provider of Pure Maintenance's patented VaPURE process.
Where the water came in and when, which rooms got wet, whether you can see or smell mold, and whether anyone has started pulling out drywall or flooring. Photos help, especially ones taken while the water was still there. Tell us the town, too, and whether the power is back on.
That depends on the schedule that week, so we don't promise a time here.
Hold off on anything you're unsure about. Furniture, framing and drywall can often be treated where they are, and the walk-through tells you which items are past saving.
Mold follows moisture, so the walk-through maps how far the water reached before we suggest treating anything. A basement that flooded and dried quickly may need far less than one that stayed wet for a week. Tell us how long the water stood and how the basement was dried.
A musty smell without a recent leak can wait for a normal appointment. Book a consultation and tell us when the smell is strongest, and if water turns up while you wait, call again.
Stop the source first. Call us and we'll talk through next steps and the earliest visit we can offer.
