Efficiency by Design

I just recently had my crawl space encapsulated, all vents sealed & a dehumidifier installed by Scott of Efficiency by Design. I cannot tell you how satisfied I am with his work & professionalism! My crawl space looks amazing! It’s clean, cool & protected thanks to Scott! I highly recommend Scott & his company “Efficiency by Design “ to anyone who needs upgrade to their crawl space or treatment of vents, etc. I couldn’t be happier! Thank you Scott for an awesome experience!

Scott and his crew were professional, made very helpful recommendations about how best to add new insulation to our attic, and were a delight to have in our home. I highly recommend them.

I recently worked with Scott Mazza, owner of Efficiency by Design, and the experience was outstanding from start to finish. Scott returned my call immediately and was able to come out to my home within just two days to provide an estimate—far faster than other companies I contacted, which were quoting 10–14 days just to come out. Even better, Scott does not charge for estimates, unlike several competitors. We initially realized we had a serious problem because our crawl space was creating a horrible smell throughout the house, clearly caused by excess moisture and humidity. After Scott encapsulated the crawl space, sealed all vents, and installed a dehumidifier, the results were dramatic. Within just a few days of the job being completed, the odor was completely gone. Before choosing Efficiency by Design, I received two over-the-phone estimates from other companies for essentially the same scope of work. Scott’s final price was literally more than $10,000 less than those estimates, and the quality of the work exceeded expectations. The crawl space is now clean, cool, and well-protected, and the workmanship and attention to detail are immediately apparent. Scott is professional, knowledgeable, and takes real pride in his work. I am extremely satisfied with both the process and the outcome, and I would highly recommend Scott and Efficiency by Design to anyone considering crawl space upgrades, encapsulation, vent sealing, or moisture-control solutions. This was an efficient, transparent, and genuinely positive experience.
