"In Sept 2025, I signed a contract with The Basement Doctor (J&D Home Improvement, Inc.) for full crawl-space encapsulation of two crawlspaces and a dehumidifier. After the work was completed, I discovered that only a partial vapor barrier was installed?none of the core components of encapsulation (sealed walls, insulation, sealed vents, etc.) were included. When I raised concerns, the first project manager dismissed them, then emailed that they had installed a ?vapor barrier per contract,? which was false. A second project manager later admitted in writing that the work was not a full encapsulation and that pricing drove their decision to downgrade the scope?without informing me or changing the contract. Despite my efforts to resolve this professionally, including providing a third-party inspection showing missing components and offering to negotiate, the company missed three deadlines to respond. "

Boiler Repair questions, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

If you’re unsure who to call to fix your boiler, you have a few options. One is to call a dedicated boiler service. However, you can also call a plumber or HVAC technician for boiler repair services. These pros will have the tools, knowledge, and experience to fix common boiler problems.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
