Get matched with top insulation install or upgrade pros in Oak Ridge, TN

"He is wonderful. Very high quality work. Works quickly and efficiently."

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"Excellent Service and workmanship This is the 4th job Dwight and his people have done for me and each has exceeded my expectations. He and his people take pride in their work and it shows in the final product. Highly recommend you calling Dwight for any remodel work."

"I highly recommend Retrofoam; it works. If you have an older home and need to get it insulated, you have two options. 1. Remove the walls and add insulation. 2. Retrofoam We chose retro foam and are very pleased with our decision. Pros: Our home gets warm faster. Our home remains warm longer. Rooms that were once colder than others are the same temperature as the rest of the house. Wind drafts through the house eliminated. Wind drafts around windows eliminated. Outside noise, reduced significantly, I mean reduced by a lot. We can now sleep with no white noise. Amazing. Overall improvement on the quality of living, physically and audibly. Cons: The inside install is messy. (These guys try hard to minimize the mess) Outside install was much less hassle and messy. (The installers do a great job cleaning up their work area.) How It Works Retrofoam is mixed from powder and water. It has a similar consistency to shaving foam from a can. It is pumped into a void or cavity inside your wall, making its way around wires, plumbing, and other obstacles in the wall. It hardens and maintains its form and placement—the tiny air bubbles in the foam help create the insulating properties. It has a low odor when installed and is non-existent after a few days. Our Story Our house was built in the 1950s with no insulation. Our brick home was constructed with hollow walls and void cavities around all of the windows. Twice windows have been replaced, once to replace the original single-pane windows and the second time to replace some storm damaged windows. Each time the windows were replaced, no insulation was installed around the window frames, allowing wind to get into the home. Combining that with the hollow walls added years of expensive utility bills and uncomfortable living space. The house temperature was so unevenly controlled, we needed to wear jackets in one area and t-shirts in the next room. We are now remodeling our home. We need a way to insulate without removing all of the inside walls. After doing research, I found Retrofoam as an option. After meeting with Mr. Eddie Sanford, I quickly decided to install the Retrofoam in my house. Eddie made the process easy to understand and helped us devise a plan to prepare for the installation. Eddie's comprehensive strategy was quickly put into motion, and the process began. Our Retrofoam project included all of the exterior walls of the upstairs living space. Mostly brick with hollow walls and old school plaster walls inside. One smaller area, 10' x 6', was constructed of block and was filled with Retrofoam upstairs and downstairs. About 1/2 of the house was accessed from the inside and the other from the outside. The outdoor installation was much more manageable and cleaner for me as the homeowner. However, not all sections of the house could be accessed from the outside. When the installation crew arrived, Robert, George, and Brandon walked through my home. Robert discussed the approach and how the installation would proceed. Before beginning, they covered most everything with plastic and began drilling holes for the installation. The holes drilled into the inside walls are 2.5 inches allowing the large diameter hose to easily access the cavity. Holes from the outside are about the size of a dime. In our case, the outside holes were made through the mortar joints. The foam is pumped into the outer holes using a brass fitting and higher pressure to fill the cavities. After completion, the outside holes were plugged using mortar and drywall compound for the interior. After the foam was mixed, they brought in the hose and installation apparatus. The hose was inserted into a 2.5" hole in the inside wall. The foam was sprayed into each cavity between the studs. Working the foam into the wall cavity from the bottom up and then from the top down. During the installation, the foam can be heard filling the hole. The installation took roughly three days. The installation crew was courteous, careful, extremely knowledgeable, trustworthy, humorous at times, and professional. Even with the typical mess that comes with construction projects, I truly enjoyed the crew's company. I found their work ethic to be top-notch. Upon completing the job, the crew chief Robert did a thorough inspection and cleanup then asked if I was satisfied. After the install, we noticed an immediate reduction in the outside road noise from passing traffic. So much reduction that we no longer use a fan for white noise in our bedroom at night. We also noticed that our house would hold heat much longer. The first night we set the heat to 62 before bed. The room temp was around 68 degrees; by morning, the temp was still 64, and the heat had not kicked on all night long. This is so uncommon; typically, the heat kicks on several times through the night. The two other areas we noticed immediately were the upstairs laundry room and downstairs bathroom. In the past, both rooms were noticeably colder than the rest of the house, requiring the use of small heaters. Now both rooms are the same temperature as the other rooms in the home. We are delighted with our decision to install the Retrofoam, and I am confident you will be too."

"Summary: For your own sanity and possibly safety, do not hire. The owner, Cory, offered an arrangement where any work that went out budget could be paid at a later date after funds were drawn out of a home refinance. Key work was left unfinished, and prior to even sending out any invoice, the owner reneged on this arrangement, threatened to place illegal liens on the property, threatened lawsuits, and threatened to report (what he thought were) unsafe conditions in the home to the city, conditions which his company was hired to fix. He then attempted to extort illegal late fees after the fact with no signed contract, all of which were well above the limit for such fees under Tennessee Prompt Payment Laws. He has some good men that work for him, (one was drinking while on the job sadly), but he is profoundly unprofessional, unstable, and has little knowledge of and/or respect for the law. Details: I am a local real estate investor and I like to do as much renovation work as I am able, but I had both given birth and had heart surgery in the summer of 2020, and was thus unable to do the work myself. I originally booked Cory’s company for another project I was about to begin, but called to cancel roughly 4-5 days before the start date since my last project remained unfinished and the contractor that had been working on it had vanished into thin air. Cory pressured me into keeping the booking, claiming that I was putting him in a bad spot by cancelling last minute, and that he’d be willing to “work with me” on my budget and payment schedule. I relented and had him to come and take a look at my unfinished project to see if it was possible to finish it within the budget, which was funded through something called an asset loan. (For those that don’t know, an asset loan is a high risk/interest only short term loan by which a private lender provides purchase and/or repair funds for a real estate investment. They only fund for fully completed items on a draw schedule, so when work is finished, they send a home inspector out to check the work is complete, and only then are funds provided.) I explained that there was roughly seven to eight thousand left in the asset loan, and that there were a few items we’d discovered that needed attention that were not on the lender’s list. Both were necessary for a tenant to move in safely; one issue was a leaking roof, and the other was rotting wood that left the back deck unstable. The rest of the work involved installing some lighting, replacing some quarter round, tiling in a shower, replacing a few broken windows, and putting down some laminate in the bedrooms. Cory assured me all could be fixed within two weeks of work (amounting to roughly 8K), probably even in less time, so I kept the booking and allowed his men to begin work. In the event the work went over budget, he made the offer to take 60-70 percent of the total amount and accept the rest later. I told him that in such an event, the rest of the funds would have to come out of a home refinance, something I was planning on doing as soon as the home was finished and I had a signed lease. After two weeks of work, the home was still unfinished, so I agreed to have one of his men stay on to finish what could be finished for another week. At this point I started to receive daily calls and texts from Cory demanding payment, which was extremely confusing, since I hadn’t received any invoice from him to date, and because I had been very clear that funding was only awarded to me when the work was fully completed. He informed me the roof was structurally unsound and was too dangerous to be fixed by his men, so I said I would find someone else to fix it. Towards the end of the third week, it was clear the work still wasn’t going to be finished, so I put my son into day care and came the last few days to help get the work done in time. It was at this point I noticed the man working on the job was taking 90 minute lunch breaks in his truck, much of the time at the property (meaning I was paying for this time), and that he’d come back to work after his breaks smelling like beer. Not the worst thing in the world I suppose, but not something I’m happy to be paying for, and probably a contributing factor to the extended time frame. This employee also lost his ladder and two small windows from the property, the former I replaced for him at my own cost (I felt partially responsible since the home was in a bad neighborhood.) At the end of the third week, the inspector was able to check off the items on the list (thank goodness it wasn’t raining that day with the leaking roof), so I provided the owner with seven thousand (two payments of one thousand and another of six thousand). I had to hold a small amount back (temporarily) to fix the deck and the roof, since if neither of them were finished the home couldn’t be leased, and if the home couldn’t be leased, I wouldn’t be able to get an investment refinance and pay him the full amount (keep in mind I still didn’t know what the final total was at this point since I still had not been sent one invoice). The owner then threw a fit, demanded payment in full, claimed I wasn’t keeping my word, and began threatening an assortment of things. He claimed I hurt him as a small business owner and messed up his payroll. This was confusing since he was the one that offered the arrangement to begin with (I wanted to cancel). I apologized and asked him why he would offer an arrangement like this if he couldn’t afford it, which only garnered more rage. He demanded to know when he was going to be paid in full (again very confusing since we had already discussed these terms) and demanded a time table. I had assumed he as a professional in this industry would know what a refinance time table was, so I had not specified that in the beginning, and he didn’t ask me until this point. I told him a week or two to finish the work and lease the home, and probably 4 weeks for the refinance process (title, appraisals, and legal). I had someone come and look at the roof, and it turned out there was nothing structurally wrong with it; it was an old home with a very steep pitch that hadn’t been built without collar ties, which aren’t structurally necessary for the roof in terms of safety. All that was wrong was it was missing a couple shingles, which I had replaced by another contractor, who financed the work for me, and I was able to finish the deck myself and a little help from the contractor. A couple days later Cory texted me and informed me he was placing a mechanical lien on the property, and that he would be charging late fees of three percent per week until the balance was paid. I calmly informed him that mechanical liens cannot include interest or late fees, and that that level of interest couldn’t be charged without a signed contract. He ignored this and then threatened to call the city and report (what he thought were) unsafe conditions in the home. Note I (still) had not received one invoice at this point for the work done. (Imagine for a moment threatening to report someone’s property for work you were hired to complete but failed to do. Insurance and/or workman’s compensation can often be separate and more expensive for roofing than other construction work, so my guess here is he didn’t want to tell me from the get go he didn’t have the coverage for roofing work and instead fabricated the “structural issues” with the roof, but I could be wrong.) He also looked up my home address and the home’s worth and demanded I pay him (since I could apparently afford it because of the net worth of the home, or some other convoluted argument; I informed him I don’t own the home in which I live anyway.) This was particularly creepy as a woman; it seemed like a a subtle, “I know where you live” type of threat. For this reason I particularly encourage people to not hire his company, especially if you’re female. I assured him he would be paid in full and that all of these threats were completely unnecessary. I had to hire someone who (fortunately) financed the work for me and finish the work m"

"Custom renovations went above and beyond. They did a good job"

"Great. Jobs got done right for good price."

"They did a great job on the installation of a new Carrier Package unit (A/C / Gas Heat) They came out on the coldest day this season (<20 deg F) to replace my 15 year old Trane unit. They removed the old unit, modified the plenum sheet metal, hooked up the gas and electrical feeds, and ran through the testing process after upgrading the thermostat. I have been a customers of theirs for 15 years. They performed all the maintenance on my previous unit."

"After using this company for 10 years on my 2 properties, because they did a good install at my Dad's, I find out that every single tech that came out over the years didn't do proper maintenance. I never went out and watched, I never looked inside at the coil and the heat. None of them took out the coil and cleaned it. The heat is filthy. The coil area is so rusty from condensation due to the drain filling up with rust and backing up and spilling down into the heat underneath and rusting out a motor. Every time, I asked why was my air causing so much water, they would tell me it was hot in the garage! No checking my coil. No cleaning my drain as they said they did. No cleaning the heat. Last night I saw this with my own eyes when a new company I hired to fix the heat and look at the air coil pulled the cover and showed me the mess. Told me I should've been keeping up with maintenance on it. Well, I was, only City Heat and Air techs were lying to me about performing the maintenace properly. The last straw was I always ask for a tech at my other property that is knowledgable with Apollo system and the last one they sent, I had to explain how it operates. In fact, that is the reason I called another company. If you use them for maintenance, go out there and watch them."

"Aire Serv of Knoxville did a great job installing our package unit. They made the process as smooth and easy as possible. Their sales representative was very thorough and professional. Their prices were competitive with everyone else and their service rose above all other previous experiences. Their technicians were timely and professional. The installation went off with no issues and they even were able to be flexible and work with us so to not interrupt our business that was open. I highly recommend Aire Serv of Knoxville!"
