They just finished the job today we just have to wait for a couple of heavy rain fall before we can close up the walls as Zavza suggested it. I interviewed many contractors for about a month I decided to go with Zavza for many reasons. One first time Jake came by to give estimate I realized how transparent and honest he is. Second Dice from the office was extremely patient with my thousand questions and understood my concerns. Over all the whole crow treated me like part of a family and treated very hard to help me. I have to add I added a couple of things in the middle of the process they were kind about it and did the best they can to meet my concerns.

I had clogged window wells that had bothered me for some time. Zavza was the only contractor that provided a drainage solution with reasonable price. Everything was handled professionally. Sure enough, I waited after two storms to post this review. The wells took a few hours clearing after a Northeaster that dumped inches of rain, but no issue or delay in draining for rain under an inch. I would recommend Zavza without hesitation.

Bert Marro (Bert)★★★★★5 months ago

I was very satisfied with their work to Waterproof our basement. They were on time, they were very diligent. I was so impressed with the quality of their work, that I also had them do outdoor maintenance that we had deferred for 20 years. They reinforced our deck, they installed a new cellar door and they matched the paint colors perfectly. We also had them repair and paint the front yard ironwork. We get comments on how beautiful and shiny our gates are!

Frequently Asked Questions — Spray Foam Insulation in Glen Cove

These are the questions Glen Cove 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 Glen Cove contractors above for exact quotes.

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