David, Flip and the removal/installation team were a pleasure to work with. I was given a detailed estimate with 4 options which were thoroughly explained to me. I decided to replace my fiberglass batten crawl space insulation with sprayed closed cell foam. The price was very reasonable and the crawl looks great! I highly recommend Elite!

The company gave me a very good price for the attic insulation installation. The only thing to know is that you have to do inspection after the work is done. They did not install enough insulation in my attic the first time. After I inspected the quality of the installation, I have to send email to describe the issue. They came back to fix the issue. They finally got the work done as I expected.

David, Flip, and the Elite team were fantastic. Our home couldn't rise above 62ish degrees inside during the winter despite our heater working perfectly fine. David and Flip managed to address our concerns quickly and they maintained excellent communication throughout the process. After the Elite team came in and worked their magic, we have been at a comfortable 72 degrees even while the weather has been in the teens outside. From top to bottom, everyone we met was considerate, professional, and clean. We would recommend Elite to any of our friends who have need for improved insulation. Thank you for your help in making sure my family is comfortable at home!

I signed up for the Constellation Home energy audit program which is part of the EmPower Maryland BGE Energy Star Home Performance rebate program. Advanced Green Home Solutions performed the energy audit as Constellation Home BPI certified subcontractor. The AGHS audit performed by Brady and Thom took a few hours and was a very thorough inspection of my 45-year-old home. A short verbal out brief was provided followed by a detailed report several days later. Their findings and solutions made sense. I contracted with AGHS through Constellation Home to perform all of their recommended improvements. The AGHS energy improvement team led by Anthony and his crew of Terrance, Antwan and John did an absolutely outstanding job installing a whole house ventilation fan, sealing the attic, installing baffles, adding 18” of blown insulation to an R-49 value and cleaning up each day. Anthony’s attention to detail was truly appreciated and serves AGHS well. His crew was very efficient and worked very well as team over a two-day period. It was apparent they were very experienced and talented. I found the entire AGHS team to be knowledgeable, professional, and courteous. Time will tell if I see any savings on my energy bill, but I can state now that the air sealing package resulted in an impressive 43% reduction of air leakage in my home when compared to the initial diagnostic blower door test. I am also anticipating an incredibly significant rebate from EmPower and BGE that should make this effort well worth the expense. Bravo Zulu to AGHS, I highly recommend!

I had AGHS insulate my home and install a new HVAC and electric water heater as part of Maryland's Pepco program for an older home. They did a great job overall! Larry, who led the installation of the HVAC and water heater, is one of the best professionals I've had the pleasure of working with. He was patient, thorough, and took pride in his work. If I ever have an issue with the system in the future, I hope he's the one they send to my home. Ashley, who handles the front desk customer support, was also very kind, communicative, and extremely helpful.

Boubacar K. came to service and install our new digital thermostat. His service was top notch, we live in an older home which required a high level of expertise for this install. He was thorough and went over all of our options for better energy consumption. We love our new thermostat and we especially like being able to use the feature that allows us to operate the thermostat remotely. We definitely recommend Advance Green Home Solutions!!

Frequently Asked Questions — Spray Foam Insulation in Annapolis

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