Ordered late afternoon Monday and received it early afternoon Wednesday. Product was all there all in perfect shape. If it works as well as the ordering and shipping process it will be a winner.

À propos de l'entreprise
Écrit par l'entreprise
It happens to thousands of homeowners each year – the sale of their home falls through because of high radon in their basement. They have to hustle to get a radon mitigation system installed and hope that the buyer will not walk away. But for many years after, they may wonder about the long-term effects of the radioactive gas on their children. Since radon gas seeps into basements from the ground, the US Environment Protection Agency had tested the obvious solutions back in the 1980's – caulking all cracks and sealing the concrete with various coatings but the improvements were not significant or lasting. Thus, the fan-based system which draws soil gases from underneath basement slabs became the standard. There had to be a better way! Novion Inc. was founded in 1987 to pursue innovative high-tech solutions. Penetrating concrete sealers, already well-proven for waterproofing concrete on major projects, seal concrete internally and permanently. Perhaps, they could be improved to penetrate deeper and seal even tighter to keep out the single-atom radon gas. After extensive research and testing, the first concrete sealer specifically developed to reduce radon infiltration through concrete was ready for the big debut – RadonSeal® Deep-Penetrating Concrete Sealer. Novion Inc. was incorporated in Connecticut and RadonSeal was made available directly to homeowners and contractors on radonseal.com website. Subsequently, we have continued to add unique innovative products, not available in stores, for basements, indoor or outdoor concrete, bricks, pavers, and masonry. Going beyond radon remediation, we provide durable and cost-effective solutions for waterproofing basements, sealing concrete slabs against vapor, and mold remediation. Our products also protect and beautify indoor or outdoor concrete, pavers, and masonry. Our mission is to supply cutting-edge, professional-grade, and environment-friendly products, superior to those sold in stores. Our customer support offers technical expertise and objective guidance on the best solutions for customers' needs. Whether you are a homeowner, contractor, or building owner, we will provide the top-quality products and service to solve or prevent problems with your basement, parking lot, pool deck, brick or masonry walls. It can be just a matter of time before your basement or outdoor concrete starts giving you problems. Act now and give us a call. We are here to help!

Good Customer Service
Very easy site to navigate.
Easy
Easy experience from beginning to end. Very thorough in explaining the products and checkout was super fast and easy!
product worked great
We did not receive our full order & no response to messages
We did not receive our full order. I left three messages with the company. No one ever called me back. I had to purchase hundreds of dollars worth of crack fill epoxy from another brand to finish my product after buying a $1000 kit from you guys. Accidents happen but the lack of response was super disappointing, especially after such an expensive purchase.

Super fast delivery-I ordered this product on a Sunday and received it on Tuesday via Fedx! Also, this product was much more easier to use than a previous product i tried "Dricore".
Arrived the very next day
Arrived the very next day! Super fast shipping, great packaging. Can’t wait to see how it works then will give thorough review. Thank you
This stuff is great
This stuff is great. I've now sealed two long cracks in my basement foundation. One crack was hairline--the tip to warm up the urethane in a bucket of hot water helped immensely. I called for some advice on what product to order, and they were great on the phone as well. Thanks!
Very responsive customer service
Very responsive customer service. Should make your website be more easy to search. Also, the polyurethane is only half filled.
DryWay Plus- Another great product
Ordering the DryWay Plus was fast and easy. They shipped within 24hrs as well.
I've used Radon Seal products before to finish, seal and stain my basement and they work great along with their epoxy for cracks
Their customer service is also very helpful! Highly recommend this company and their products.
