Customer experiences differ sharply. One customer praises low heating bills and soundproofing in a Simplex modular home, while other customers describe a delayed build and basement flooding after an egress was left open at one home, and moldy materials and electrical problems at another.

We are in our fourth year of living in our Simplex modular house and we are loving it. Our heating bill is very low for both summer and winter. This house is completely sound proof and a solid .

I can’t at this point recommend Simplex. We signed a contract and paid a deposit for a 2400sq ft home in October 2019. We are still not in the home. I rarely leave reviews for anything, but felt it is my obligation to share. Best case scenario we will be in late this Fall. They also had a rebate for essential workers, which they refused to honor because the house wasn’t completed in time, which is something they have more control over than I. When I decided to go with Simplex I contacted them direct and used their recommended builder and architect. I can’t in good faith recommend them to anyone. Do your research, there are a lot of other modular companies out there. I will update my review once the house is completed to share my final impressions. UPDATE: The original review was from August 2021. I am providing an update as of February 2022. I am lowering my review from 2 stars to 1. Once the house was set the rear basement egress was left wide open for 5 months allowing continuous flooding. This hit a tipping point when tropical storm IDA came through and we had 6ft of water in the basement and thousands of dollars in damage. No preparations were made for the storm even though we had experienced flooding in the egress during light precipitation. The builder was absentee and there was no one taking responsibility for the job site from the start. I had to personally take on a large portion of the expense of getting the basement cleaned up and take a large amount of time off work. After the house was set we did not get electricity for 5 months, water for 4 months, and heat for 7 months. These utilities would have taken even longer if I didn’t get involved and push the issue. The home came with a natural gas fireplace. On first use, the fireplace was installed incorrectly and ignited the house on fire causing damages near six figures. Thankfully no one was hurt. The fire department was able to save to home, but a lot of our personal belongings were damaged, and we now have a hole in our living room wall. It is 2022 and I am not living in the house we purchased in October 2019. We are stuck in a small apartment while the fire damage is repaired. The fire happened a month ago and we are still waiting on Simplex to give the go ahead for the repairs. No rush on their part I guess, it’s not their house. When the house was set there were some noticeable spots with water damage. I sent photos to Simplex and the Builder. Both assured it would be taken care of. When the fire repair company was doing inspections, they found mold where the water spots were. I guess they thought it could just be hidden with a fresh coat of paint. Now for the more minor issues. The yard grading is poor and the garage floods when it rains. There are several interior doors that do not stay shut or lock. One of the living room windows does not shut all the way. Some of the interior trim isn’t nailed down. One of the HVAC vents was completely rusted out. HVAV return didn't have a filter. The vinyl flooring was bubbling up in several spots. Our driveway hasn’t been finished either. Simplex has not reached out following the fire, nor have they honored the essential workers rebate I brought up in my first review. Do not go with simplex unless you are prepared to be misled and slowly financially bled out over several years for a home that is damaged. Going with Simplex and using their builder John Sullivan dba JS Modular Homes has been a massive financial mistake. Imagine paying for a home and almost 3 years later you’re living in an aptartment. My rep at Simplex was Sean McAllister My contact at JS Modular was John Sullivan. He is a one-man shop, subs everything out. I was not happy with the work. Dealing with the fire damage repair company has been a sigh of relief to finally work with someone who knows what they're doing. You will see this is the only review I have ever left for anything. This has truly been a terrible experience. Take your business and money elsewhere. Photos attached.

We had a terrible experience with Simplex. Our house was constructed with moldy materials. See attached pictures. We hired an industrial hygienist to test the trusses in the picture and the tests came back positive for mold. Simplex refused to pay for remediation and admitted they have no quality control process in place to prevent this from happening again. Then we found error after error. Simplex conveniently "forgot" to wrap our house in Tyvek. They also gave us the wrong set of kitchen cabinets but claimed they didn't know what I was talking about when I questioned them about it. In addition, there were many electrical problems. I had to hire an electrician to open up walls and fix things, add light switches that were missing, and change the placement of light switches because door trim would have covered them. In addition, Simplex admitted that we paid for a more expensive truss system even though we never requested one from the contractor with whom we were working. It was too easy for Simplex to blame it on contractor rather than take responsibility. In addition, there is no automated process to select finishes. We literally had to email our requests one by one. They could easily create a Google Form (for free) to automate this process, but I don’t think anyone there knows how to do that. They are still operating in the dark ages. Finally, it’s telling that so many of their employees post Google reviews. It’s obvious that they were asked to do so to drive up the overall ratings. FYI…Glassdoor is where employees should post reviews, not on Google. Do not waste your time or money building a modular home. We built a stick home before this house and the process was much easier and more cost effective.

The builders are nice, staff is super friendly, but check other fabricators for prices.
