Very happy with the job Rob Card and his team did removing the fiberglass insulation from our attic and replacing it with closed cell foam insulation. Crew was thorough and conscientious and did it in two days.

Michael Stewart★★★★★7 years ago

Used them in about 2012-13. They did a great job, were easy to work with, and were cost competitive. Would use them again.

Sarah was delightful, professional and dedicated to making sure all area's of my home were inspected and taken care of. Albert and Ian did a wonderful job with installing all energy savings measures and the improvements have made a tremendous difference. My home is SO Snug now. Working with Snug Planet has been great, the receptionist is so nice, the work done is perfect. They worked so hard and went above and beyond to get all projects done, cleaned up everything, even vacuuming my stairs for me. Thanks Alot.

Snug Planet recently sealed up our crawlspace after noticing some moisture problems during an energy audit. The team did a wonderful job sealing and insulating the entire crawlspace and it only took them two days. We have noticed a large improvement on the quality of our indoor are and can feel the floor and crawlspace area are warmer because of the insulation. They did a great efficient job of a very difficult task. I highly recommend their services.

Snug Planet did a home energy audit for us and then installed insulation and sealed the rim joists in our basement. Heather, the young expert who performed the audit, was prompt, professional, and communicated the issues and tradeoffs very clearly. She checked on one possible remedy with a more experienced colleague and determined that it would not be worth the money. I appreciated that. The installation team did a great job and was careful to clean up after. Paul, the team leader, pointed out that some of the spray foam stuck to our basement carpet. He was willing to pay for a replacement, but it’s a ratty old carpet in the basement. No problem. Best of all, our house is now noticeably warmer. Last night I checked our bedroom temperature more than 4 hours after the thermostat had turned off for the night. Even though the outside temp was 38F, the inside temperature had dropped only 2 degrees.

This company was a joy to work with. Susan in the office was super kind and helpful every time we spoke. Alex handled our assessment and project planning with integrity and professionalism. Mike, Chad, and Aiden who did the actual insulation/soffit vents, etc, were very friendly, hard working, cleaned up the work area, and finished in one day. I appreciate the smaller size of the company and how transparent and “non-salesy” they were. Highly recommend!

What a great investment to your home. I collected some data and as you can see the spray foam in the basement made a huge difference. Temperature is 4-5 degrees warmer, humidity down 10%. For accuracy here are the details of the data: 1- placed a sensor push thermometer in basement 4 feet from wall , 4 feet off ground. Temp & humidity was measured in 5 min intervals and I used the daily average to nearest degree 2- basement heat vents were open up until the work was done. Closed after (1/22 & 1/23) 3- my house is generally kept between 63 at night to 66 if we are home during the day 4- on 1/20 I moved the sensor up onto the actual rim joist which is why the average is so low 5- humidity decreased 10 percent and I no longer run 2 dehumidifiers, just 1. Very easy process, great employees. Dylan was very helpful and polite. Not a pushy salesman but one who used facts and information. Work crew was respectful of home, even offering to clean my floor before leaving. Chuck and his partner (can’t recall name) were very attentive to detail and made sure work was done right.

AB Insulation is by far the best at what they do. My son and I had a number of insulators give us estimates (one didn’t even bother to call back or email their estimate) but AB Insulation was immediate. They sent us the invoice, scheduled the insulation and did an amazing job. I was over my son‘s house the other day and took a look at what they’ve done. They were thorough. They clean up the areas very well and insulated areas that would have possibly caused heat to escape the home. They recommended cellulose which they placed in every area that they could, and then when there was an area that would not hold the cellulose, they placed traditional blow in fiber insulation into those areas. AB Insulation are not only professional, but extremely knowledgeable and friendly. Their communication is outstanding and they answered every question we had. There is truly only one insulation company that you should hire—AB Insulation. thank you for your honesty your honest pricing and your service.

Recently had Don and his crew re-side my entire house. Very professional and holy cow, it was done in just 3 days. Would absolutely recommend them to anyone for anything they need done.

Dena Aravantinos★★★★★a week ago

The experience was fantastic. Kevin did an excellent job of determining our needs and outlining what needed to be done. The workers, Toby, Vince and Ronaldo were courteous and proficient in the insulation installation. Dan, our inspector, informed us of our energy saves and potential future work. All in all an excellent experience!

Joanne Hall★★★★★4 months ago

We recently just had our house fully insulated and our house was built in 1954. Our house had no insulation and we would freeze during the winter or be very warm in the house during the summer. Now with all the insulation done is so nice and comfortable. We would be normally at 78 degrees in the house with central air and now we are at 68 and nice and cool. The service was incredible. Great job cleaning everything up and the guys worked all day non stop in this heat we had this past month. Josh, Johnny and Tim were very friendly and helpful during the whole process. The gentleman Dan who came to check out everything was done correctly was very informative And polite. Highly recommend this service. Our windows are old and just can’t get over how comfortable our house is and the quietness from not hearing everything outside. The sound barrier is amazing now. We hear nothing going outside. Please use them you will be happy!!!

They did exactly what they said they were going to do. The guys were very professional. They explained everything to us and showed us the work that they did. We no longer get icicles the way we did, and the house feels much warmer. We highly recommend them. Very satisfied customers!

Rachel Scott★★★★★2 months ago

We used ZeroDraft to better insulate our home a few weeks back, and I have to say the process went very smoothly. Our home feels more comfortable now! On top of this the customer service offered by Karen was a big part of the projects success. I would definitely recommend her and the company to anyone who is looking for an affordable and high quality service!

Lyn Rice★★★★★5 months ago

Zero Draft recently insulated my home through a grant program, and I was incredibly impressed with the whole experience. The crew arrived right on time, worked efficiently, and clearly knew what they were doing. They were courteous and respectful of my space—and when they left, everything was clean and put back in place. I’m already noticing a difference in comfort, and I expect to see energy savings soon too. I really appreciate their professionalism and quality of work. I highly recommend Zero Draft to anyone considering home insulation or energy upgrades.

Frequently Asked Questions — Spray Foam Insulation in Ithaca

These are the questions Ithaca 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 5 verified Ithaca contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Ithaca?▼
Homeowners in mixed climates like Ithaca, NY 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 Ithaca?▼
For most homes in Ithaca, NY, 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 Ithaca, NY?▼
In Ithaca, NY 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 Ithaca costs $2,000–$6,000. Most Ithaca 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 Ithaca, NY?▼
When searching for a spray foam contractor in Ithaca, NY, 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 Ithaca 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 Ithaca 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.
