Spray Foam Insulation in Orange, CA

I called for an estimate and Javier showed up on time and looked at my crawl space. He was not at all like the others that tried to push things to increase the cost. I hired them to do the job. He never asked for a down payment like others. Javier and his crew showed up to do the job on time. The day was hot and the humidity in the crawl space was terrible but his crew suited up and went down in the crawl space. They proceeded to remove the old insulation and replaced with R30 insulation, they worked quickly done in 3 hrs. They were extremely professional and after made sure everything was cleaned up. My husband and I went into the crawl space after he arrived home from work and they did an “ABSOLUTELY AMAZING JOB!!” I would highly recommend them. Thank you Javier and Crew!

First off, Javier is a class act. He was a pleasure to work with and made the process extremely easy. Before choosing his company I brought in five different outfits to bid the job and feel them out. Orange County Foam was by far the best as far as price and quality of work. If you are considering getting some work done call them first!!

OCI installed closed cell foam insulation on my exterior walls, garage ceiling, and attic during my house renovation in Hastings, NY. They were very professional, provided all the paperwork I needed to pass inspections, gave me a reasonable price, performed the work quickly, and cleaned up after themselves at the end of the job. They were thorough and sprayed even smaller miscellaneous areas before they wrapped up. Overall, a great experience.

This is good i recommend it to anyone who is interested

I am thoroughly impressed with the quality of work and customer care. Thermal Nest provided a tailored solution for our older home with a challenging attic layout. Their crew was skilled, patient, and ensured every corner and eave was properly insulated and sealed. The before-and-after difference is remarkable. Our home now retains warmth on cool nights and stays cooler during the afternoon heat. A trustworthy and highly skilled company serving the Orange area.

Choosing Thermal Nest was one of the best investments we've made in our home. The entire process was seamless, with excellent communication from start to finish. They addressed both attic insulation and crawl space sealing with impressive professionalism. The crew worked diligently, protected our property, and cleaned up perfectly. The improvement in our daily comfort and the home's overall energy efficiency is significant. We finally have the cozy, consistent ""nest"" we wanted.

Recently call these pro's for a partial home remodel. They were clean and polite when getting into the attic. Very pleased with the warm roof they applied.

Great family owned business! Cody and team are very professional and their attention to detail is by far the best! Contact them for all of your insulation needs!

I should have had the attic install done in the winter time. Having them install attic insulation for 4 hours (with a faulty machine) in a 130 degree attic in a San Fernando Valley summer was not a great idea. It feels like they gave up at the end (ie the vertical insulation is already falling down because they did not have the right length fiberglass and instead blew cellulose on top of it). We paid them a lot of money, and they measured our attic and had access to our attic 3 times before the insulation install. It seemed weird for them to run out of materials. I hope they will honor their warranty. Will update soon. I wish they would have installed a 3.0 Quiet Cool Fan rather than the 2.0 Quiet Cool Attic Gable Fan. That would have been better in our extremely hot climate.

Attic Projects > Inspection Review I had the pleasure of working with Vincent from Attic Projects for an attic ( and crawl space) inspection, and I can’t recommend enough. He was punctual, prepared, and extremely knowledgeable, arriving with all the proper equipment, a respirator mask, and boot covers before entering my home. He took the time to sit down with me, go over every detail item by item, and clearly explain the costs and scope of work. More importantly, he was empathetic and genuinely cared about helping me understand my situation and what steps I could take to make my home safe and habitable. I’ve had four different companies come out to inspect, and Attic Projects is the only one offering a 10-year warranty on their work. That alone speaks volumes about their confidence and quality. I haven’t hired them yet only because I’m giving my HOA one last chance to act, but based on my experience so far, Vincent and Attic Projects stand out as top-tier professionals in this field. Highly recommended.

Honored Warranty. Highly recommend! The Attic Projects team did an attic clean up, rodent proofing, air sealing ( to house) and insulation in 2022. They have a 10 year warranty vs rodents. In 2025 After hearing rat activity in the attic I went up and saw evidence of rat burrows and many droppings. Their team came out without within a few days, confirmed the recurrence, sealed up a few potential points of entry and set more traps. After continuing the catch multiple rats over extended period of time it was determined the best course of action was to remove the blown in insulation and search for all points of entry and seal those up. While no company wants to redo a job they handled it very professionally. Simply, its covered under our warranty and we will take care of it. They sent out a team removed all insulation, came back multiple times over a few weeks sealing up potential points of entry. After no more rats were caught for 2 weeks we schedule the insulation installation. The team arrived exactly at 8am, took measures to minimize contamination to the house (i.e plastic barriers), very professional and thorough. They did not solicit this review. I highly recommend this team. Peace of mind that they guarantee their work and you are dealing with professionals. I have recommended them to my neighbors and others.
