I had a great experience. Gerardo has great communication skills. He was there when he said he would. Gave me the estimate same day promptly and only 3 days later his team was there completing the job. I did the closed cell insulation in my attic. My attic is a converted room for my teen and would be impossible to live in during summer months. I’m hoping the closed cell insulation will be the solution but already the days are in the 30’s degree cold and my attic is at 68 with no heater turned on yet. I think it’s a good sign that it will keep out the heat in the summer. Great experience with Gerardo. A lot of theses guys are so unprofessional and some don’t even show up so this interaction was very positive. We decided to do the tear down ourselves but Gerardo has a team that can do demo and building back up the Sheetrock. A lot of insulation companies don’t offer that service. Definitely consider him!! ⭐️ ⭐️ ⭐️

Gerardo did an excellent job on my recent project for a new construction build. He clearly communicated when he would come and how long it would take to finish the work. His work was neat, clean, professional, and on time. I will be using him for my future projects and recommend him to others as well.

Ralph and the crew members did a great job when we needed new insulation put down in our attic. Ralph was always available and patient whenever I called/texted and explained the process step-by-step (and I called multiple times). The crew themselves were timely, professional, took extra precautions to ensure a 'clean' job, and showed me the steps as they were working. We were very pleased with Atticrawl and how they conducted business from beginning to end of the job.

I experienced rodent and bat infestation in my attic which necessitated extensive remediation. I was fortunate to find Atticrawl LLC who were experienced in this type of work and did a fabulous job in the cleaning and disinfecting with the removal and replacement of contaminated walls, joists, plywood, insulation and wood. Atticrawl also rodent and bat proofed my attic and house by sealing all identified points of entry inside and outside. The remediation took about nine hours with many workers involved in doing the various parts of the work process. It was amazing to watch how everyone had their own job and they were all working at the same time doing their part of the total job. I cannot say how impressed I was with the whole process.

Great experience from start to finish. Tre showed up on time and reviewed the job with me. He made recommendations and shared pictures. He was respectful of the property (wore boot covers) and was articulate. We agreed upon a price and scheduled an install time. The installers called prior to arrival as agreed and showed up on time. Very nice and the crew of 4 sealed off the area and covered the floors . After they removed old insulation and vacuumed and sealed, they asked me to review it prior to installing new. Weird how satisfying it is to see your attic so clean. They then finished and did a great cleanup job. I was asked to inspect/review again and was not rushed. The crew of four hustled the entire time and knew what to do. So glad i hired them. They actually did what they said they would do and my install looked just like the pics they had shared.

Jesse was the one who did our energy audit and the attention to detail, level of professionalism as well as just the vast amount of knowledge from him was absolutely unmatched! We are in the middle of a full-scale renovation and electrification for an older Victorian home and that in itself comes with a lot of complicated problems that require both creative and well-informed solutions. Jesse went above and beyond during our audit - he had suggestions and solutions for things that we did not even think about, and it felt like he understood every issue we wanted to mitigate with this project. He was extremely courteous and respectful of our home and genuinely took his time both answering all of our questions and performing an extremely thorough energy audit. His knowledge of building science is extensive, and in his time doing the audit and answering all of our lengthy questions and concerns we understood that this is a very competent expert in this field. Our post-audit review was with Mason and Jesse, both of which again were very thorough and took the time to address our very specific and complicated questions about our large project. They made themselves available and proved themselves knowledgeable throughout the entire process. My husband and I wholeheartedly recommend Ciel’s services to anyone looking to make their home more energy efficient. You will be hard-pressed to find a group as professional, knowledgeable and competent as them - a traditional insulation and HVAC approach won’t give you the tailored energy efficiency approach that makes best use of your resources and available rebates/incentives. Thanks Jesse and Mason!

Michael R. was absolutely outstanding! From start to finish, he went above and beyond to deliver not just great service, but a genuinely positive experience. He was punctual, professional, and extremely knowledgeable in his work. What really stood out was his attention to detail and the way he took the time to explain everything clearly, making sure I was comfortable and fully informed. Michael carried himself with a level of courtesy and respect that is rare these days. He clearly takes pride in what he does, and it shows. I felt confident the job was done right the first time, and his friendly personality made the entire interaction easy and enjoyable.

Frequently Asked Questions — Spray Foam Insulation in Woodbridge

These are the questions Woodbridge homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 3 verified Woodbridge contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Woodbridge?▼
Homeowners in mixed climates like Woodbridge, NJ typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Woodbridge?▼
For most homes in Woodbridge, NJ, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
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 in Woodbridge, NJ?▼
In Woodbridge, NJ and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. 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 in Woodbridge costs $2,000–$6,000. Most Woodbridge 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 in Woodbridge, NJ?▼
When searching for a spray foam contractor in Woodbridge, NJ, look for ones 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 Woodbridge 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 in Woodbridge 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.
