Sylvia & Warren personally reviewed our house, and found the best location for the radon mitigation system (for an existing structure). Warren and Pat installed the 6 inch pipe and RadonAway fan. They took care of the electrical connection and roof repair. Another quote that I got was twice as much as Cavalier's, and I would have to get my own electrician and roofer. Very happy with our system, and results have been less than 1.0 pCi/L over the past week (measured by my RadonEye detector). I highly recommend them! read more

I sent a contact request to Cavalier and had a same day response. We set up an appointment time to meet at our home. Sylvia and Warrne were on time for the meeting. There were very friendly and personable, highly knowledgably about Radon mitigation and after a thorough inspection of the home had a multi-tiered approach to reducing the radon level in our home. The work was done in a professional manner, being attentive to protecting our floors and home. Our Radon level went from 14.1 down to .52. We are very happy with all aspects of the process and highly recommend Cavalier. read more

BUYER BEWARE!!! Cavalier Corporation refuses to complete a job they have been paid for in full. The only communication they have provided us confirms they are completely liable for installing our radon system, but they have refused to do the electrical work required to get their installation to code, stating they were not liable for electric. However, the paperwork they provide clearly states they are responsible for electric on all pre-existing builds. Despite this and numerous verbal commitments to honor this agreement, they have accepted payment for the job but outright refuse to complete it, going as far as providing false information attempting to remove the liability they are fully aware falls on them. They then knowingly provided false information about the condition of our home when we complained to the BBB trying to rid themselves of the liability they knowingly hold. (Warren stated I "continuously complained" about issues with my home when he was out at my house (Aug 9) - the only thing I ever stated to him was an apology for taking a minute to open our front door as it had just been replaced and I was in the middle of painting), in addition to numerous other blatant factual inaccuracies. Unfortunately, Warren fails to recall the only complaints from the day he came to my home were a result of him stating that Sylvia was the one who inspects properties and had not communicated the electrical situation with him, and when I voiced my dissatisfaction with them not being prepared to complete the job on the day they scheduled. I found it unprofessional for him to complain about a fellow coworker (who I later learned was his wife, making it all the more inappropriate). He openly complained about the lack of communication, then stated we would have to wait until his journeyman returned from Europe, then said we should hire an electrician in the meantime if we didn't want to wait. I clearly stated that the quote they provided included electrical work and we expected to hear as soon as the journeyman returned and would expect work to be completed shortly after his return. I also stated that as the buyer of the home and due to the conditions of the sale and the terms of their agreement with the seller, I am not liable for any additional costs and expected to be contacted as soon as the Journeyman would be able to come and complete the work. That never happened - yet another empty promise from Cavalier as they pocket money they have not earned according to a quote THEY provided. Cavalier provided a quote of $300 after the home had been open for quotes, which clearly stated it included electrical work on existing builds. With the help of my real estate agent, the seller chose Cavalier as that was a pretty good deal for the work needing to be done. Unfortunately, Cavalier refuses to take responsibility that is clearly claimed in writing on the forms they have provided us. From our experience, this company has shown a history of poor communication, extremely unethical business practices, and complete disregard for honoring their commitments to military families solely working to ensure their homes are up to VA standards. We would have NEVER entertained their offer/quote had they been honest about the terms, or if we had any hint that their behavior would be this atrocious and completely against any realistic view on how companies should handle business. I highly discourage working with this extremely unethical business, who has worked tirelessly since July to take advantage of a busy military member that hired them when they sold the home, and our family that has been stuck trying to get them to complete a job they had promised would be complete prior to July 14, 2017. Save your money and go with a company that doesn't hold your money hostage refusing to complete the job and leaving your home in SHAMBLES with extension cords literally stapled to the ceiling because Warren and Sylvia do not find value in ensuring their work is up to code. read more

I have been involved in construction since 1995. I have used Cavalier Corporation on a number of projects for radon systems. On a recent project, I spoke with Sylvia (owner) regarding the option of doing a non-vented conditioned crawl space in Spokane County. Sylvia informed me that it was allowed with a polyethylene barrier that would need to be sealed to the foundation. I moved forward with a construction project only to discover from the Spokane Building Department that non-vented, conditioned crawl spaces had not been allowed in Spokane County for 10+ years...as they do not meet current energy code requirements. I contacted Sylvia to discuss and directed her to the Spokane County Building department for confirmation...which she received. I expressed my frustration (Sylvia offered no solution - just confused). We had a number of conversations that I would be forced to go with a vented crawl and a standard radon system. I would also have to incur additional expenses for fire barrier insulating the crawl as a result of the inaccurate information she provided. Unfortunately, Sylvia was still confused when it came time to complete the under slab work. She failed to correct the original work order and instructed her crew (husband) to install the polyethylene barrier that she was told several times was not allowed in Spokane County and/or no longer applied to this project. Then, she proceeded to invoice me 4-5 times the cost of a standard active radon system and file a contractor's lien against my client's project as a means of extorting money for her mistake. This is a "mom & pop" company that has not kept up with current building codes. I would not recommend. read more

This company honors their contracts and we have never had an issues with them. They operate with the highest level of integrity. Pre-system we had a radon level of 119. After the system was installed we have a level under 2 and per our contract they have ensured our level stays under 2. During the summer, when the house vents are open, there is no radon detected. I highly recommend this business. read more
