I needed my two workshops insulated so I called Creative Conservation in Roanoke, since they do all the work for Habitat for Humanity where I volunteer. The initial conversation with Brandon was quick and hassle free, and he made recommendations that helped me better understand the pros and cons of my options. He emailed me with a quote that night (a Tuesday) and said they could start right away. Well the first crew was here bright and early on Monday morning, as we agreed. William and Luz were great to deal with, worked hard and finished the removal of the old insulation in one day. They were very professional and also did a great job of cleanup. (Also, it’s kind of nice to see a woman in the construction industry for a change. Kind of a ‘Flashdance’ throwback, for those of you of a certain age.) The spray insulation crew, Juan and another Brandon, showed up Tuesday morning with a different truck containing the spray equipment. They applied plastic sheeting to EVERYTHING so overspray wouldn’t get on anything, and even helped me move a bunch of my junk out of one of the shops (I thought I still had time but they needed to start on the one I hadn’t cleaned out yet). Here’s the really amazing part: the temperature was very high this week, mid to upper nineties. Juan, who did the spraying, had to don a tyvek (plastic) suit and full face mask, stand on a ladder in the peak of the roof and spray insulation (which itself comes out of the nozzle at 140 degrees) for hours. And mind you, since the entire building was covered in plastic, there was not a breath of airflow in there. I can vouch that it felt like a pizza oven. With never a complaint. Superhuman. Overall I’m extremely pleased with the job. Great job, nice people. And they even left both buildings cleaner than when they arrived. Thanks, Creative Conservation.

My wife and I moved to Arlington about a year ago and at the time passed on insulating the basement. Our home is a 1998 house built on a 1920's foundation. The insulation and attention put into insulating the basement at the time was lackluster. Coming from California, I didn't really understand what a mistake I had made until the mice found refuge in our basement this November in 2019. Needless to say, they took over, and it made for a rather unpleasant holiday. I found a great mice and rodent cleanup crew (Environmental PC) who recommended Creative Conservation, and specifically Richard Browning, who runs the Arlington area. Impressive, attentive, kind, and thorough are the best words to describe Richard and CC. Richard squeezed me into a tight slot early after the holidays to assess my place. He was prompt with the quote, answered all my questions (even down to the technical details about how the foam was made, how they transported it, how it worked etc.). I felt like he really had my interests in mind. The quote he generated was extremely reasonable. What impressed me most, however, was not just the initial service, but the execution and flexibility. Because our basement was infested, we weren't just insulating. We were getting an environmental crew to clean up, grinding and redo'ing the floors, and then foaming in the gaps all around the edges of the basement to seal out future critters. This required some schedule wrangling, and on the day that Richard's crew was supposed to show up, the basement squad was running behind. Richard knew that our family had suffered from this mice issue, and worked quickly to reschedule the foam treatment, coming in just a few days later, despite having little scheduling flexibility on the calendar. It was this effort to do the right thing and take care of us that really stuck with me. Of course, the best thing out of using Creative Conservation is that their work was incredible. They foam sealed all the corners and gaps in the basement in about an hour and a half. Our basement is now dry as a whistle (we also have sump pumps though), but before there was a serious draft due to the poor sealing that was put in during the 90's. Our de-humidifier which used to run non-stop even during the winter, hasn't come on since. Temperature wise, the basement now stays the same temp as the rest of the house. We are SO grateful to Richard and his team. HIGHLY recommend this to anyone in the Arlington area that's looking to seal their basement, keep out critters, conserve energy, and just make the basement a more pleasant place to store stuff.

I used Davenport for my new construction house. They did all of my insulation and did a fantastic job. My contact was Dustin who was great with responding and getting out to get my jobs done. They were very efficient . I would definitely recommend this company:)

Similar to others, we had a poor experience with Davenport. They quoted the job and saw the height of our crawlspace, but once they got onsite to do the job they said the crawlspace was too small. They also forgot to insulate several interior walls that we included in the quote.

I had two jobs scheduled with Davenport Insulation. The first was to get insulation blown into my uninsulated garage walls. Two men and a truck showed up to do the work. They were polite and fine, but kept telling me how it was a new truck and that they had to keep turning the pressure down. One of them was frequently on the inside of my garage pushing against the drywall. Not having this done before I didn't know if this was standard procedure. After they left I discovered that about 40% of my dry wall was blown off the studs. I have had to go back and screw the drywall back in place. My salesman, a guy named Mark, quoted me a price on seamless gutters. We scheduled a date. I called the day before to confirm I was on the schedule. He said I was. The next day no one showed. I called the office and they said I was never on the schedule. I tried to contact Mark several more times to no avail and was then told he had been replaced by Levi. I have been told 4 times by both office staff, a supervisor, and Levi, different dates where my work would be done. They have no showed on every single one. I started this process in February, it is now August and I still don't have gutters. Amendment to my review written on 24Aug2018: Even though I had asked to speak to a supervisor on my last contact with Davenport Insulation in Winchester, I was never contacted by them until I wrote this review. Mike E. contacted me within a week of this review being posted and I now have gutters. He assured me that this was an oversight brought on by my salesperson leaving and that this is not how they normally treat their customers. While that doesn't explain all the previous contacts I had, I will take them at their word. Gutters are installed.

Frequently Asked Questions — Spray Foam Insulation in Winchester

Is spray foam insulation a good investment in Winchester?
For homes in mixed-humid climates like Winchester, VA, 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 VA 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 Winchester?
In mixed-humid climates like Winchester, VA, 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 VA'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.
