These guys work fast! They were able to get my attic up to an R60 in a matter of a few hours. The prices are also unbeatable in my opinion. Very much worth it!

The guys recently installed more insulation in my attic to reach R-49 rating. I just noticed my heating fan is not running. Which means the house is finally holding in heat. Thank you guys! I will be recommending your services to my neighbors.

Super professional and polite crew. Pleasure to work with and needless to say they did a super job on our insulation in a complicated old house. We were so pleased that we used them agsin to do our Crawl space encapsulation. Reasonably priced and quality work. Ron , the owner, monitors and works on each job.

Spray foam makes your home energy efficient by blocking these small gaps in walls, ceilings, floors and basements.

We were at our wits end and had already called a real estate agent, thinking we had to sell and move because of the extreme smoke from the neighboring townhouse that was coming into our unit. Then our son recommended Foam Works. Ron and his team listened to our concerns and were confident they could fix our problem, and that confidence filtered through to us. The process of removing our old insulation and fixing loose ductwork and drywall and all the other prep work was quite impressive, the foam installation then went quickly with no issues. Ron’s team was knowledgeable, friendly, and clean. We now feel cocooned in our townhome with no smoke! Two unexpected but noticeable benefits are outdoor silence and we’ve had to raise our A/C temps about 2 degrees. We feel sure this will be reflected in future utility bills. We will wholeheartedly recommend Foam Works to everyone we know from now on.

Found CHS based on Google Reviews and Ratings. Scheduling request was a breeze. Zach responded out for an initial and thorough home insulation assessment. He was very professional and took his time to explain options and reasoning toward developing a very comprehensive plan and helpful approach for the project. During installation from both teams, the prep and project was completed as stated and in a very non rushed manner, which was mostly appreciated. All calls and updates were equally appreciated as well from the office and responding teams. Would highly recommend CHS to others in the future.

In March 2025 I purchased exterior wall insulation (Dense-Pack Insulation) from Complete Home Solutions and the results have been fantastic. The original problem was that my house would not stay warm in the winter and would not cool down in the summer. I already had HVAC but I would also need to run space heaters or window ACs to get my home to a comfortable temperature which was very expensive. A Complete Home Solutions representative came to my home and did a very professional walk though. I had a week to make up my mind for the price quoted. I got quotes from 2 other companies and they had different approaches to the insulation process. Complete Home Solutions' process was the least disruptive and fastest. The insulation installation itself took 2 full days (each floor took 1 day). The team was very professional, worked quickly, and checked in with me to provide updates and ask for specifics. They did a good job cleaning up once they were done. TOTAL COST was $15,263.98 for all the exterior facing walls of my 1,144 sq ft house. My house now keeps a good temperature both upstairs and downstairs. I waited almost a year to leave a review so I could give feedback on both the service and the results.

I received services through the Weatherization Program and was very impressed. The team was professional, thorough, and did excellent work. Although the process took a little longer than expected, it was well worth the wait. They did a great job overall, and when a small crack appeared after replacing the toilet vent, they promptly came back and fixed it. I truly appreciate their service and would highly recommend this company to anyone. The photos were taken while the work was still in progress.

Frequently Asked Questions — Spray Foam Insulation in Waldorf

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