"I used this company to perform a home inspection before I bought my house. Due to its negligence and breach of contract, 9 months after I moved in, I had to replace the roof on the house. The company will do nothing to rectify the situation. They are cheats and liars that hide behind their contracts. Their inspectors take every shortcut, and they will not protect you during the home buying process. Just don’t use them."

"I have been a customer of Hedayat for well over 9 years, from the time his ad appeared in Angies List. He is an expert on all things carpets which means as an appraiser, in addition to the cleaning and repair services provided, the quality of the work is the best it gets. My carpets thanks to the care given, all continue to look as they did when I brought them back to the US from the Middle East 14 years ago. I highly recommend Art Connection to those members who are seeking expert evaluation of and care for their prized Oriental carpets."

"We needed a structural engineer to inspect the foundation of a home that we are purchasing and were recommended to contact Kemp. We are so glad that we did. Greg provided first class service. He was thorough and took the time to explain each step that he was taking, the purpose behind it, the potential results and what each could mean, and finally the actual results. He also took the time to educate us on some of the basic indicators of good and deficient or damaged home foundations. He was very personable and is great at making complex information simple enough for novices to understand. He also provided the inspection report almost immediately. We highly recommend Greg and his company’s services."

"Setting up the service was an efficient process with the representative listening to what we needed done and providing a (reasonable) price over the phone. On the day of our service, the two-man crew was punctual, friendly and efficient. We initially walked through the house identifying all the registers and discussing the process. They then went to work and continued diligently and efficiently for over four hours. We were impressed with their attention to detail and care for our house (covering their shoes with "botties" when coming in from the wet outside; laying down when they started, a drop cloth by our front door where they stationed their heavy-duty HEPA vacuum; and then going around after they finished to vacuum bits of dust and paint that had fallen on our floors near registers that had been detached). Excellent experience."

FAQs for radon gas abatement projects in Ashburn, VA

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
