"Paul cam to assess the mold on my basement walls and he didn't just come in a look. He went above what we thought he'd do and inspect the baseboard in the entire basement. He also checked oitsode to see where the moisture could be coming in from. He was very efficient and helpful with providing information on air filters, remediation, and potential causes and how to prevent. We would use him again."
Ground water infiltration occurred through the concrete slab in two rooms on the ground floor of the house causing water damage and mold growth on the overlying flooring. The cause of the water infiltration appears to be associated with cracks and a crater in the concrete slab, which is believed to have been caused by pile driving work being performed during the construction of an adjacent building.
Mold in HVAC Coil Compartment
Construction/demolition work in an  apartment unavoidably released high levels of dust that migrated into adjacent apartments. Dust containment methods, such as negative air filtration and poly sheeting, should have been used to prevent dust migration into adjoining spaces. Settled dust samples were collected from a table & curtain rod in a nearby apt, which revealed the presence of substantially elevated levels of silica and asbestos in the dust. Asbestos and silica are known carcinogens.

"David inspected a potential home I was looking to purchase and he was so thorough that by the time we were done it gave me a very clear understanding of what issues the house had, what needed fixing and what was downright dangerous. When buying a home, you need a great inspector like David because if you don't get a good inspection you run the risk of buying a big money pit. I bought a home once before but that was a joke compared to the great inspection David did. The home David inspected was a small 1200 sq. home but it was built in 1935 and so he did mention we should expect to see some things pop up. However, he went above and beyond and I am so grateful for his hard work that I will recommend him to others in the future as well and will call on him again for inspections. He also brought Alex, a septic inspector, with him who was also very thorough and very good and provided a very through report. Thank you, David, for your wonderful help! You have no idea how much I appreciate it."

"We had had a new kitchen put in and then a year later, we had had our kitchen floor redone and basement repaired after a flood in our house.  Water from our washer had flooded the kitchen and laundry room and then flowed through the floor into the basement theater room and rec room.  We had to have a new (porcelain) tile floor put in upstairs and new paint and carpeting throughout the basement.   The work for the new kitchen and then the flood required a huge amount of sanding, spackling and more sanding...etc. The dust in our house was a big problem afterwards from the spackle dust that accumulated  in our ducts.  We decided to have our ducts cleaned and found All States on Angie's list.   It went great!  They were on time, conversant about the state of our ducts.  They did the job.  I have noticed that the air is better in the house and we have much less dust on furniture!  Very happy with their services and I would definitely hire them again.

"We were very pleased when we called Go Green Express during a heat wave. The company who usually services our equipment wouldn't call back as they were too busy, even though we were regular customers. Over the phone, Go Green helped diagnose the problem so the tech could arrive with the correct part. The technician, Jameson, arrived and was polite, knowledgeable and professional. The office called and confirmed our appointment and got someone out quickly, even though we were not regular customers. We would absolutely use them again."

FAQs for radon gas abatement projects in Cold Spring Harbor, NY

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.
