If I could leave 10 stars I would. This company came highly recommended by our framer. Dave was straight forward with his quotes and all communication, his guys came when scheduled, and they did an excellent job. His guys were polite, neat, and worked very quickly. They protected our windows and cleaned up everything before they left, you wouldn't even know they were there. Look no further than Insul-Tech Energy Solutions for your spray foaming needs. It's not often you find a company that is the best at what they do, and they are the best price. Seriously, don't even bother getting other quotes!

I had Standard H&C install a new furnace for me on 10/27/2025. It was a great experience dealing with both their office and the 2 workmen who did the installation. Isaiah and Elijah worked efficiently and finished the whole job in about 6 hours. They were both pleasant to work with and extremely polite. It was a pleasure to have Standard H&C do work in my house. I just can’t say that about other companies I have had in the past. I also had Standard perform a routine check on my air conditioning in August/Sept which prompted me to have them do my furnace. I will continue to use them going forward.

Complete attic insulation remodel, air sealing and removal of old insulation. Replaced with blown in cellulose to R60. Fair price, Travis is great to work with.

Salvatore Sturiale★★★★★2 years ago

I couldn’t speak more highly of a business. Travis who is the owner of Saratoga Cellulose & Foam was absolutely phenomenal. He uses an incredible product, and is extremely knowledgeable in his field. Travis was very responsive when I contacted him with any questions about the project and scheduling. The estimate provided by Saratoga Cellulose and Foam was more reasonable than any other company I contacted. Travis and his team showed up on time and completed the job efficiently and in a timely manner. The area was prepped properly and there was no mess left behind. I highly recommend this company.

Used for attic closed cell spray foam. Derek was prompt with scheduling and providing estimates. He was very informative and helped answer all my questions. The crew was clean and took time with layering applications to allow proper cure time. Now we have a conditioned attic space allowing ac to run more efficiently, save money on heat, and keep storage space.

Phil R.★★★★★2 years ago

Great company. We've used them for several remodel projects on our home and they were prompt, professional and reasonably priced. I would recommend them to anyone.

Jacob Middleton★★★★★5 years ago

I worked with Ray at Correct Energy. He was super informative and helpful in figuring out how to insulate my home. He spent significant time both giving me information and explaining things. The crew worked within some difficult time and site issues, but finished the job in the timeline. The price was great as well! I am very pleased with the service and work.

Rose Kennedy★★★★★a year ago

What an absolute DREAM! Correct Energy is an incredible company. Knowledge, professional and efficient! I contacted a few insulation companies but the proposed methods were not through. Correct Energy and especially Ray’s knowledge and experience were above and beyond. CE came out to assess and spent a generous amt of time explaining EVERYTHING. CE came when they said they would. The crew was professional and spent a few days here. They left everything immaculate. My place is old, built in the 1940’s so many challenges came up that they handled like absolute pro’s. Their work has and will continue to save so much on energy, the difference of before and after is immediate and drastic. I can’t wait for them to come back and do my basement next! I can't say enough about this company. Pros work here!!! Hire them!!! You will not be disappointed..

judy steele★★★★★a year ago

Correct Energy is amazing! Ray and his crew came in and assessed my spray foam needs for a non conventional style new build and exceeded all my expectations. This company cares about their clientele, you cannot go wrong with choosing this company! I would give them 6 stars if I could!!

Frequently Asked Questions — Spray Foam Insulation in Troy

These are the questions Troy 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 Troy contractors above for exact quotes.

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