My husband and I are impressed with their responsiveness to all my questions and quality of their work. We did not have insulation in the house and needed it installed asap in our exterior walls due to miserable overheating in the house. They took good precautions to cover the floors and furniture, took their time to do the job right, finished everything in the estimated time frame, and took care when cleaning up. They just left and we already feel the difference in temperature. We are very happy and totally recommend this company!

Excellent work by Miquan and his team! They completed attic insulation, spray foam for my loft, and full duct replacement. Miquan was very knowledgeable, took time to explain what my house needed, and was always prompt with responses. The team was extremely professional throughout the project - respectful of my home, arrived on time, and maintained a clean work area. They actually finished the job ahead of the promised timeline, which was a pleasant surprise. Quality workmanship throughout and I’m already seeing improved comfort and energy efficiency. Highly recommend for insulation and ductwork services.

On Wednesday Axel walked me through the whole process a couple of times. He immediately won my confidence and I signed up to get the job done by Rywen. I could not wait for the work to start. The team of workers arrived Monday morning as per agreement - they displayed nothing but professionalism as they prepped the house with paper walkway and plastic tunnel leading to the ceiling opening. Like clockwork the old insulation was sucked out and new insulation laid down piece by piece and secured. In the unfinished basement, where rat infestation was evident, all the junk piled up over more than three decades was removed and hauled away. The foundation and walls cracks were sealed to keep mice and rats from entering the premises. The kitchen was thoroughly inspected for cracks in the walls and cabinetry. Where necessary, cracks were treated with the application of sealant and or with wire mash. I am confident I made the right decision to go with Rywen. I highly recommend them.

Rywen Insulation is an excellent company! Every step of the way was thoroughly explained and completed in a professional manner. Axel did the initial inspection, Walter led his team with the job of replacing insulation, disinfecting and rodent proofing and Roni was super helpful with an electrical issue I had. Everyone at the company was pleasant, knowledgeable and patient with my questions. I highly recommend them!

John M★★★★★3 weeks ago

I was very happy with Rywen’s customer service, communication, and attention to quality. I was especially impressed with their suggestions, for example, ensuring we got the desired thickness of insulation in the attic, overall, plus providing my desired amount of future access. To me, it felt like the company has a consistent attitude of going over and above and that’s rare. Thanks!

Great service and great work. Juan and his team did a great job under my house in the tight crawlspace. It was rat infested. The ducts and insulation were totally soiled and ripped to pieces. They cleaned it all, put in new heating ducts and Rat proofed the entire house. Always in communication. Thank you for all of your hard work. Before and after photos 👍😎

Judi M Pelz★★★★★2 weeks ago

Great experience! Juan , the owner, came initially for the estimate for the cleaning of the crawl space. We set the date and Alfedo with 2 helpers showed up on time and finished the cleaning job (including sealing rat holes) as agreed to in 2 days. We decided to go forward with the insulation and vapor block sheeting and again excellent service! They were pleasant and on time and did a great job. The price was competitive but well worth the expense. Again Juan was very nice and was prompt with estimates and explained everything that they would do! I would highly recommend them and this company.

I had a few companies come out to our home for attic cleaning and new insulation installation estimate. I decided to go with Trioteam because I felt that they were very thorough and honest on their inspection and were very detailed about the process of doing the job. Giovanni's crew came out to do the work, they were very professional and showed me pictures of the entire job.

Edward T. Hawthorne★★★★★3 years ago

German and the Trioteam team did an great job installing insulation in the attic over my garage. Their prices were very reasonable. German was very professional, responsive, courteous, and always kept me updated. He was prompt and on schedule, neat, and cleaned up and left our house in order. I would definitely use them again and definitely recommend them.

Alex Wang★★★★★4 years ago

During the winter time, we just moved into a new house and noticed that the floor was freezing and needed insulation. We called Trioteam for a free inspection and estimate. The inspector, German, was responsive and gave use detailed description of the materials and process. In addition, he was able to give us a great value for the whole process. Trio team is also very efficient. They were able to install the floor insulation the next day, and they were able to finish within 2-3 hours. If our attic needs new insulation, I would recommend Trioteam.

Frequently Asked Questions — Spray Foam Insulation in Oakland

Does spray foam insulation work well in hot dry climates like Oakland?
Yes — spray foam is highly effective in hot dry climates like Oakland, CA. While moisture control is less of a concern than in humid climates, the air sealing properties are critical for keeping hot desert air out and cooled air in. In extreme heat climates, an unsealed attic can reach 150°F+, dramatically increasing AC load. Spray foam in the attic can reduce attic temperatures by 30–40°F.
What is the best area of my home to insulate in Oakland?
In hot dry climates like Oakland, CA, the attic is typically the highest-impact area to spray foam insulate. Desert sun heats roofs to extreme temperatures, and an uninsulated attic transfers that heat directly into your living space. After the attic, crawl spaces and rim joists are the next highest-impact areas. A local contractor can perform an energy audit to identify where your home loses the most 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.
