JWS Mechanical & Construction Reviews by Satisfied Customers
It was a great experience working with this team for a cottage build in 2022 and 2023. JWS helped us with the majority of the construction (foundation, in- floor heating, framing, roof, siding and windows/doors).
I was really impressed with the skill & craftsmanship and felt confident my project was in good hands, which means a lot when I couldn’t be on site.
These guys have a wealth of knowledge, and care about doing a job right.
I’m very happy with the results which we’ll be enjoying for generations!
I was recommended another company for a small garage furnace install, needless to say the other company wasted 5-6 weeks of my time.
I contacted JWS and within 2 weeks they were out to install the garage furnace.
They were honest, did a great job on the install, and very fair price wise. I will be contacting JWS for future HVAC projects!
Very happy with JWS. Quick to answer my call, when I needed an on-demand water heater on Dec 28th, 2023.
Julian and John were professional, and courteous and answered all questions about my new system. I highly recommend them.
Julian was great to deal with for my HVAC issue. Friendly, knowledgeable, responsive, thorough and on time! Highly recommend Julian👍😊👍
