Crawl Space Mold Removal Falls Church, VA

We do crawl space mold removal in Falls Church under houses of every age, and some of the oldest nearby were built over crawl spaces from the start. When ground broke on Pimmit Hills in May 1950, 1,280 of its 1,642 homes went up on a slab or a crawl space, by the civic association's count, and owners later added back porches, basements, garages and second stories.

Census estimates for 2020 to 2024 still date 37.6 percent of the 2,314 homes in the Pimmit Hills area to the 1950s, and about three in four are detached houses. Our mold remediation page covers how we treat the rooms above.

“I had a doubt about having mold in our home. I contacted enviropure for inspection and they were quick to setup an appointment for free inspection even after I mentioned it's just a doubt. They willingly drive almost an hour to come to our home, checked it out and clear all our doubts. They suggested few things to take care as well. They couldn't find any mold so we haven't used their mold removal service but we are happy with their professionalism. Their client first approach was evident in their communication and honesty in their service. We for sure recommend their service.”

“This is a great company and very easy to deal with. They fully explained their treatment procedure, guarantee and payment methods upfront. Their price was a fraction of the cost of traditional mold removal methods and was quick and painless. Plus we didn't have to schedule weeks in advance! We'd definitely recommend them to friends and family in need of mold removal!”

“We just completed an 8-month renovation! After tearing out walls, replacing flooring, and cleaning out the crawl space, we decided to bring in Ron and his company, EnviroPure, as the final step in the process. Ron is genuinely passionate about the Vapo system and the results it delivers, plus his son is one of his lead technicians. The entire treatment took about 6 hours, and when we returned, our home had a noticeably clean, sanitized feel. I highly recommend Ron and EnviroPure!”

“I worked with EnviroPure and Ron about a month ago to get a visual inspection and approval done for the closing of my home. I strongly recommend using Ron and his team to anyone interested in mold mitigation or inspections. Ron is fantastic and beyond helpful. We will use EnvirePure again in the future for sure.”

One house can sit on two foundations.

An addition may stand on its own footings, over a separate crawl space or a slab, joined to the original house at a seam in the floor framing. The two sections can be vented and insulated differently, and one can stay dry while the other stays wet, so we map moisture in each section we can reach.

Tell us when you book if part of the house was added later. An addition's crawl space may have its own hatch or an outside door, and we want to reach every section on the same visit.

The vapor barrier decides what comes back.

Bare soil gives off moisture into the air above it all year. A plastic vapor barrier over the ground slows that down, but only while it covers the soil and stays intact. A torn sheet, a gap at the walls or a corner pulled back by a plumber lets ground moisture through again.

Water pooled on top of a barrier is arriving from somewhere else, usually a downspout, a plumbing leak or a low spot in the yard. Installing, replacing or sealing a barrier is a job for a crawl space contractor. Have the mold treated before any new liner goes down, so the growth isn't sealed in under it.

Vents, ducts and summer air.

Foundation vents let outdoor air in, and in July that air is humid. When it meets wood and ductwork cooled by the house above, moisture can condense on them, which is how a crawl space ends up damp in a dry month. Supply ducts running under the floor can sweat enough to soak their own insulation and the joists beside them.

Some owners close the foundation vents for the summer, and some crawl spaces have been sealed by a contractor. Both change how the space dries, so tell us what has been done down there before the visit.

What comes out from under the floor.

Insulation batts that have fallen onto the soil and soaked up water come out, and so does any joist or sill plate that has started to rot. Sound joists, the underside of the subfloor and the sill plates are treated where they are, and the estimate separates the two lists.

What treatment day looks like.

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.

Frequently Asked

What homeowners ask us.

After. Treat the growth first so it isn't closed in under the new liner, then let the contractor seal the space. Our moisture mapping shows them where the water was getting in.

A dirt floor feeds moisture into the crawl space air around the clock, so it usually needs a vapor barrier once the mold is treated. A crawl space contractor installs the barrier.

The treatment deals with the mold and doesn't change how much water reaches the space. Keeping a crawl space dry takes a repair, such as a barrier over the soil, a fixed leak or downspouts carried away from the foundation.
