Tim was very thorough! He helped us feel comfortable and confident that we would get a quality spray foam job done. So far we have done our attic and above our garage. The temperature has been controlled and it feels so much cleaner we can store things in there without having to worry so much about mold and humidity! Excellent service from Tim and Vicki!

Alice Tackett★★★★★a year ago

Mr. Johnson and his son Brad and the entire work crew worked tirelessly to complete our job in a timely manner. The goal was to rid our crawl space of black mold and then apply foam insulation and a water seal so our home would have a healthier environment and we would be well insulated for winter! While doing the job they found other structural issues that needed to be addressed. The Johnson's wanted to make sure all important things were fixed and in order before completing the job. They were very thorough and pleasant to work with. I would highly recommend them for your next home improvement project!

Mr. Randy and company are the BOMB! We bought a home requiring major crawl space renovation. They save us a ton of money while providing awesome customer service.

We had a very positive experience with this company. Tim did exactly what he said he would do at the cost he quoted over the phone. Very, very happy I chose to use spray insulation over fiberglass. Our house is now airtight and solid. Their work was excellent as well. Very, very satisfied!

Ryan Griggs★★★★★4 years ago

Tim and his team are pros! I hired them to install foam on my new construction roof decks (attics). They did a professional job and left the place clean. They got the job done sooner than estimated. I will definitely be having them do more work for me.

Dale Howard★★★★★3 years ago

My house is almost 30 years old. The blown in insulation had settled a lot. Central Ky Spray Foam removed all the old insulation and put spray foam on the rafters in the attic. We have had some cold nights since, and my whole house is warmer, with my heat pumps running less. What little mess that was made, they cleaned up. Very happy with the contractor and the job that was done. I would recommend them, and the spray foam insulation!!

We lost our heat just before the temperature plummeted. Called another local company (FHA) who didn't do a great job diagnosing the issue. I, not knowing better, spent nearly $700 for a small part that solved the issue for a couple hours before the heat went out again. Synergy was incredibly professional and helpful. Thank you to Bryson and Davy for the installation! They were both kind and professional and did a great job cleaning up afterwards. Our tech, Drew, and salesman, Brandon, were very knowledgeable and I could tell they really cared about getting us taken care of. Our heat exchanger was broken, and Brandon pointed out we were at risk of carbon monoxide leaks. He advised we shut our system off and even offered to bring us some space heaters. That part I spent $700 on? Synergy was nice enough to give us a little bit of a discount for having already spent something which was really great. We will certainly be going to Synergy for all of our heating/cooling needs from now on!

I had a great experience with Synergy Home! From my first phone call thru the completion of replacing my HVAC system. Brandon, Kimberly and Davis all were personable, Knowledgeable, professional and thorough. They answered my questions and pointed out things I hadn’t noticed. The price was reasonable and they came two days after I accepted the estimate to install the system. They would have came the next day, but I wasn’t available. Great company, people and GREAT job!

Dan Ayers★★★★★3 months ago

Thermal Guard did an amazing job on our attic spray foam encapsulation. Our attic is split into several sections, but they handled the complexity without any issues and sprayed 8 inches of open cell over every inch. The difference was immediate! Our attic feels comfortable, and the HVAC barely runs now. Do you want to know what makes them stand apart? Attention to detail. We had our basement done a few years ago by another company and it was nothing but problems. Thermal Guard is on a different level. Highly recommend if you want quality work and no shortcuts.

Liz Polly★★★★★a week ago

We highly recommend Thermal Guard for spray foam insulation, led by owner Steve. Steve was professional, offering competitive pricing and clearly explaining how the foam insulation works. The team was punctual and demonstrated high standards of work quality, which included a complete clearing of the old insulation and excellent, thorough clean-up afterward. Communication was clear and effective throughout the project. Most importantly, the results are immediate: our attic temperature is now consistent with the main level of our house, confirming the significant improvement in our home's comfort and energy efficiency.

Insulation Shout Out. (November 2025) I appreciate the excellent work done by Weatherization Plus (Versailles, KY) in adding insulation to my attic. The two-man installation team (Ian & Kagan) arrived on time, set up quickly, and got to work. They were respectful of our home and took time to set up their hoses in a manner to cause the least amount of mess inside our house. After completing the work, the crew picked up and left everything as it was before they arrived. For my attic, I requested 12 inches of cellulose over top of my existing insulation to reach a rating of “R-60”. Owner Brian Padget calculated the amount of insulation required as part of his quote (taking measurements and inspecting the existing insulation and determining what prep was needed to tighten up the air slow in the attic prior to installation). The installation went quickly (just a few hours) and the finished result looks like a smooth blanket of gray snow filling the entire attic. I’ll update this post in the spring once I see how our investment affected our winter heating bill. Mr. Padget is very knowledgeable regarding all types of insulation and he can help with any attic prep work needed prior to adding the blown-in insulation. It was a pleasure discussing my project with him and hearing his suggestions. I priced out doing this job as a DIY project but in the end decided that Weatherization Plus’s quote was reasonable and using them saved me from dealing with the mess of installing cellulose insulation myself. I strongly recommend calling Brian if you are looking to make your home warmer this winter.

Dean Stoops★★★★★2 months ago

It is hard to get excited about a “new attic” but I am thrilled. I had a real problem with poor insulation, insulation in contact with light fixtures in violation of code that could have caused a fire, leaking flex ducts, and multiple air penetration points. Brian Padgett and his crew at Weatherization Plus extracted all insulation, installed baffles, sealed all duct work, air sealed the floor of attic at all wall top plates, light fixtures, electrical and plumbing penetration points. Once that was done I took a week to build elevated walkways before having them come back to install 12 inches of blown in cellulose insulation to reach R-40. Thank you Brian Padgett, Austin Gill, Ryan Crump, and the rest of the Weatherization Plus team for the excellent job you did in my attic. I could immediately tell the difference. What was an uncomfortable and hard to cool second story, is now a much more comfortable living space. Thank you Weatherization Plus! Update: After all the beautiful work done by Brian Padgett and his crew a couple of weeks ago to seal and insulate my attic, I discovered a major problem with my HVAC and had the entire system replaced. This necessitated an insulation “touchup” following instillation of the new HVAC system. I contacted Brian to see when he could work me in. Robby Owens and Eric Young were there bright and early the next morning and had a new layer of freshly blown insulation blown in within an hour. Just in time for the carpet layers to start laying carpet. I am thoroughly impressed with Brian’s timely response to my request and the great work done by Robby and Eric. Five stars are not enough for Brian Padgett and the team at Weatherization Plus in Versailles. Thank you for outstanding service and quality work.

Spencer Dillehay★★★★★4 months ago

I had Weatherization+ come out to blow some insulation into my attics and install some insulating board along the knee walls, which share a wall with a guest bedroom and my recording space where I work. The problem I had was that the attic would heat up when the sun hit the roof, the air would get warm and then travel between the attics via an airway beneath the floor. This meant I was being roasted from all sides— the floor and walls would grow quite warm and radiate heat into the living space. Brian came out to appraise the situation, and we set up an appointment to fix the issues. The guys came out and worked hard all day. The very next day I could feel the difference. Not only that, I have a digital thermometer in the room which logs temperature data. I’ve included a graph where you can see that some days it was pushing 90 degrees up there before the new insulation, but after the install, the peaks and troughs are much smaller. This means that there is less variation in the temps— it’s not getting nearly as hot and it tends to keep cooler longer. Now we hit in the neighborhood of 82 or 84 up there—on sunny days, which sounds hot but just feels warmish. It’s a major positive difference. Insulation is the kind of expense that pays dividends both in lowering your AC bill and also improving how you enjoy your home. If you’re reading this and wondering if it’s worth the trouble— it doesn’t cost anything to get a quote, and everyone who worked on my project was knowledgeable and thoughtful— they took great care to protect my carpet and flooring from damage and bits of insulation. It’s worth a look— give em a call!

I’m very pleased with the attic insulation work and the entire experience. Ty was the first person I spoke with and he was courteous, answered all my questions, and clearly explained the process so I knew what to expect. Donnie and Travis were also very professional and respectful—they made sure to keep my cats safe by letting me know whenever they needed to leave the door open to blow in insulation. They cleaned up thoroughly and confirmed I was satisfied with the work before leaving. Highly recommend!

They drove 2.5 hours for a small job and did it well. I received small-cell spray foam for two exterior bedroom walls. They did the job on time and on price, and the folks were very personable. They even scraped the excess foam from the studs to facilitate drywall installation. I will use them again!

Efficient! Two extremely polite technicians applied spray insulation in a difficult-to-access space in our attic. They were very respectful of our home and planned their access route to ensure no damage occurred during the process. Thanks Donnie!

Ten stars! We hired James Hinkle and his crew to encapsulate our overly moist crawl space (new vapor barrier and spray foam throughout). They scheduled us in ASAP and did an absolutely fantastic job. After finding so many corners that had been cut, in this home that we just purchased, we are beyond relieved to find people who do the job right the first time. We will be recommending them to all of our friends and neighbors who need insulation work done!

Stephen Bird★★★★★7 years ago

I am a repeat customer of KY Spray Foam Insulation. They added spray foam to a 50 year old addition that we never could keep as warm as the rest of the house. Worked like a charm. Unlike most contractors, they showed up when they said they would, finished on time and left no trace of being there. Excellent service! Could not recommend them enough.

We had our home attic insulation increased today with blow-in fiberglass from Quality Insulation. Our experience couldn't have been better, the team came and introduced themselves, begin to lay floor protecting plastic throughout to area where they would be moving about and worked continuously until the installation was complete. I inspected the job in the attic and it looked as I had hoped. When they removed the floor plastic the left over debris would have fit in child's teacup. Yes I would recommend them to family and friends. Thanks

Frequently Asked Questions — Spray Foam Insulation in Lexington

Is spray foam insulation a good investment in Lexington?
For homes in mixed-humid climates like Lexington, KY, spray foam is typically an excellent investment. The combination of hot summers, cold winters, and significant humidity means your home faces insulation challenges year-round. Spray foam addresses all three — providing thermal insulation in both seasons while controlling moisture infiltration. Most homeowners in KY see payback periods of 4–7 years. As with any tight building envelope, ensure your home has adequate mechanical ventilation to manage interior moisture.
How does humidity affect spray foam insulation performance in Lexington?
In mixed-humid climates like Lexington, KY, moisture management is as important as thermal performance. Closed-cell spray foam acts as a Class II vapor retarder, preventing moisture from infiltrating walls and attics where it causes mold and structural damage. This dual function — insulation plus moisture control — is why spray foam outperforms traditional insulation options in KY's climate. However, because the building envelope becomes tightly sealed, proper mechanical ventilation is strongly recommended to allow interior moisture from daily activities to escape without losing conditioned air.
Is spray foam insulation worth the cost?
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic costs $2,000–$6,000. Most homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor?
Look for contractors who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
