Keeping water out does most of the work, and Fairfax County reimburses half of eligible floodproofing costs, up to $5,000 per property.
Mold prevention in Falls Church, VA means keeping a house dry once the leak is fixed and any growth has been treated. Mold spores are part of ordinary outdoor air, so the part you can control is the moisture that lets them settle and grow indoors.
Our part is finding the moisture source, treating what has already grown with the VaPURE process and finishing with an antimicrobial protectant. Your part is the repair that stops the water, and the county has rules and money that help. If you can see mold now, start with mold remediation; if you only suspect it, start with mold inspection and testing.

“Ron did a great job explaining everything. I am so excited about this process. Initially I was planning to use a mold remediation company for the whopping price tag of $25K. Enviro Pure is charging me $5K and I don't have to replace all my drywall, kitchen cabinets, carpet and furniture which the mold remediation company had instructed me to do. I'm very excited about this.”
“After mold remediation Enviropure fogged our house to kill the remaining mold spores. The staff are knowledgeable and considerate. The service was done timely and quickly and my breathing improved almost immediately. Highly recommend!”
“Working with EnviroPure was excellent. They were professional, personal, and thorough They listened carefully to our needs and goals for optimal health of our home so that we can all start feeling better. I highly recommend them.”
“This review is long overdue. I discovered mold in a closet in a basement room this past fall. I reached out to several different services for quotes. Ron was very responsive and provided a fair quote. Working with him and his team was fantastic. Ron got my home onto his schedule quickly so that I could accommodate guests for the holidays. He also helped me resolve the cause of the mold, as opposed to just mitigating a problem that would return. He was not only incredibly professional, he was also kind. I wholeheartedly recommend EnviroPure to resolve any mold issue!”
“Very professional! They will explain things to you and they offer free estimates! Most likely will save you lots of money, it’s definitely worth checking them out!”
“Ron and his son did a fantastic job, working around schedules and price was unbeatable value. Thank YOU.”
On the first visit we walk the property and map moisture in the walls, floors and ceilings. Everything we find goes into the written estimate: where the moisture is, what it has reached and what we would treat. That list doubles as the repair list for whoever fixes the source, so the leak and the mold get dealt with in the right order. Book the repair before treatment day.
If the source is humidity rather than a leak, the fix is ventilation: bathroom and kitchen fans that vent outdoors, a dryer vent that ends outside, and a dehumidifier in a damp basement.
Fairfax County's Stormwater Service District pays for the county's own stormwater pipes, channels and facilities. The gutters, downspouts and ground around your house are yours, and rain that runs toward the foundation ends up against the basement or crawl space wall.
If water from a neighbor's yard or the street drains onto your lot, ask the county whether it is a stormwater problem it handles before you pay to regrade.
The county's Flood Mitigation Assistance Program reimburses 50 percent of eligible floodproofing costs, up to $5,000 per property, according to its flood advice from March 2025. The same advice says most homeowners' insurance policies don't cover flooding, so read yours before the next storm season.
Ask the county what counts as eligible before you hire anyone.
Cooking, showers and laundry put water into the air of a closed house every day, and in winter it settles on whatever surface is coldest.
Check that the range hood blows outdoors. Many recirculate through a filter and back into the kitchen, which moves the steam around without removing it. Put lids on pots that simmer for a long time, and leave the hood running for a few minutes after the burners go off.
Laundry dried on racks indoors releases its water into the room. In winter, hang it where an exhaust fan is running, or use the dryer if it vents outside.
A quick look after big storms and at each change of season catches moisture while it's still a small repair. If a musty smell turns up with no visible cause, our odor removal page explains how we trace one back to the mold behind it.
Heavy rain comes in early spring too: on 16 March 2026, 1 to 2 inches of rain brought an areal flood warning for Tysons, Vienna, Falls Church and nearby areas. Clear the gutters after the leaves come down in fall, so they are open before the spring storms.
Write down what you find and when. A damp patch that shows up after every storm points to a different repair from one that appears only in August, and the notes help whoever you call.
In winter, look at window sills and the corners of closets on outside walls for condensation. In summer, look at the basement, the crawl space and any ducts running through the attic.
These are the places worth a flashlight and a minute:
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.
EnviroPure is a licensed provider of Pure Maintenance's patented VaPURE process.
The active component of the sterilant is on the EPA's Safer Chemical Ingredients List.
Call first if you're not sure where the water is coming from, because the moisture mapping on the first visit shows it. Either way, fix it before treatment day, since the protectant can only help once the water has stopped.
It can if the moisture comes back. 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.
It can send water toward it. Mulch beds piled against the foundation, sprinklers aimed at the walls and downspouts emptying into planting beds all put water where the basement or crawl space wall soaks it up.
Shut off the main water valve, and in summer leave the air conditioning or a dehumidifier set to run. Ask someone to look at the basement after any heavy rain, since a slow leak in an empty house can run for weeks before anyone sees it.
A newer house still gets leaks, overflowing gutters and bathroom steam, so the seasonal walk-through applies whatever its age.
Call us and we'll talk through next steps and the earliest visit we can offer. The consultation is free.
