Tucker Stone★★★★★3 years ago

We had Jose and his crew redo our attic insulation in August of 2022. He removed all old insulation, vacuumed all left over debris, and then installed all new insulation to all three different attic entrance points along with heat shields throughout the attic to increase insulation of our house. He was very knowledgeable and professional about everything from the moment he gave us a in person quote to completion of work. He went above and beyond our expectations and I would recommend Jose and Insulation JB to anyone needing insulation work.

Gabriel Grimaldi★★★★★2 years ago

Jose and his team did a fabulous job replacing the attic insulation, fixing gable vents, and installing a new attic door. The team was fast, efficient, thorough, and clean. Outstanding service at a fair price. Very respectful crew and a very high-quality job. We were very happy with the results and will recommend Insulation JB among our friends and neighbors.

Julie Artherholt★★★★★2 years ago

We rate Insualtion JB with 5 stars. He was awesome! We chose him after reading the reviews posted. It was truly the best choice. Jose came to our house and recommended what we needed. He explained why and went into detail how the cost was calculated. He installed radient barrier, blown in insulation and sealed the a/c vents. We could tell a difference in our house not long after the job was completed. He was professional in his work and he knows his business. We would recommend him to anyone who asks.

Super happy with the whole experience. David and his staff were remarkable. Booking was easy and convenient as we used them before to reinsulate our attic. Due to a roof leak, some wet material had to be removed, the area was treated for mold and reinsulated. They also added a solar attic fan to help cool the attic. We recieved a text the morning as promised that Pedro and Magider were on the way, they showed up on time (even early!). They placed floor protection on the stairs and all flooring and did a great job of clean up when completed Job was completed in a couple of hour, so super efficient as well. Highly recommend. Positive, Responsiveness, Punctuality, Quality, Professionalism Attic Buddies are an excellent to work with and I highly recommend.

Outstanding service and top-tier quality from Attic Buddies I am writing to share my fantastic experience with Attic Buddies. I recently hired them for an Insulation installment and I was thoroughly impressed from start to finish. What truly set them apart was their honesty, communication and timeliness. For instance,  I scheduled an estimate on Saturday, we met with Mr. Dave on Monday.   Mr. Dave presented with knowledge, identified all areas of concern and recommended products that would help the longevity of the insulation in the attic.The administrative team Ms. Melysa, contacted me to schedule and confirm the appointment for Friday. She was very polite, professional and initiated a welcoming atmosphere for Attic Buddies. Attic Buddies completed my main attic and garage attic on Friday.  Pedro and Chino, worked very efficiently in the high heat temperature of the attics. Pedro and Chino remained organized and kept all working areas clean.  It's rare to see a company go the extra mile like this. The entire process was seamless and stress-free. The end result exceeded my expectations in terms of quality and value. I am a very happy customer and will definitely be returning to Attic Buddies for future needs. I highly recommend them to anyone looking for any repairs or replacements of your attic needs .

Dave the owner was great he came early to scope out my attic since I’m unable to get up there to take pictures for him. Pedro and Chico worked as a team efficiently and non-stop till the job was finished. They were careful covering the floor as not to make a mess or track anything throughout the house. I’m extremely pleased with the awesome work ethic and the product they used.The insulation should help lower my electric bill.

Sales - quick appointment made and salesman showed up on time. Scope of the insulation job was well defined. The price was fair and the job was scheduled. Workers - crew showed up on time band were polite and professional. They took care to put down floor coverings. They applied depth markers to demonstrate that they were applying adequate material to meet the R49 rating. Once I had the opportunity to review their work, I approved the job as complete. They blew excess insulation out of A/C pans and the plywood flooring. They posted the R49 rating in the attic. From first call to the completion of the job, they exceeded my expectations.

Alec★★★★★2 months ago

We had our attic insulation replaced in our residential home in Magnolia by Lone Star Thermal, and would highly recommend using them. The initial consultation was collaborative, and the team was knowledgeable of spray foam versus fiberglass. I ended up settling on R-49 blown fiberglass and we could immediately tell a difference in our home. I received multiple quotes on our job, while Lone Star was not the cheapest it was a fair price and the job was done on time and as expected. The team followed-up after completion to ensure the punch list was closed-out. Thanks again!

I’m a custom builder in The Woodlands and I had Chris do all of my insulation work the last few years. He always has extremely competitive pricing and his install crews do high quality work. In fact, I like Chris’ work (and low prices) so much that when his old Texas Insulation Co. phone number didn’t work when I called it for my next job, I had to do a number of Google searches to find that Chris had started his own insulation company, Lone Star Insulation Co. Chris and Line Star Insulation Co just did another excellent insulation job for me in Carlton Woods. I highly recommend Line Star Insulation Co and Mr. Chris Volger for pro insulation work at great prices.

We had our attic retro fitted with spray foam through Inscoat and I couldn’t be happier with their services! They were prompt, easy to deal with and very professional. They went above and beyond with their on-ratio technology and gave me peace of mind our product was solid! Don’t use sketchy spray foamers whose prices and schedules are “too good to be true.” Go with the true professionals at Inscoat!

Emily Dondzila★★★★★3 months ago

UPDATE: Had InsCoat back out to spray our new room extension and they did another stellar job! They responded quickly, worked efficiently, and left the worksite clean. They've exceeded my expectations on a big and small job and both times they treated my home like their own! Definitely recommend! ✅️ Quality work in our shop, very happy with the service. Answered all my questions and cleaned up all of the job debris after the job.

Very professional! Showed up on time. Superintendent was on site from start to finish. Completed project in a timely manner. Crew cleaned up when job was done. Very competitive pricing. Highly recommend!!

Frequently Asked Questions — Spray Foam Insulation in Conroe

Is spray foam insulation a good choice in hot and humid climates like Conroe?
Absolutely. Hot and humid climates like Conroe, TX are actually where spray foam insulation delivers some of its best results. Closed-cell spray foam acts as both an insulation layer and a moisture/vapor barrier, preventing the humidity infiltration that causes mold, rot, and air conditioning inefficiency. Homeowners in TX typically see 20–35% reductions in cooling costs after installation. One important note: because spray foam creates a tight building envelope, proper mechanical ventilation is essential in humid climates to manage interior moisture from daily activities like cooking and bathing.
What type of spray foam is best for homes in Conroe?
In hot and humid climates like Conroe, TX, closed-cell spray foam is generally recommended for exterior walls, crawl spaces, and attics. Its high density creates a moisture barrier critical in humid environments. Open-cell foam can be used in interior walls for soundproofing and actually allows some vapor movement, which can be beneficial in certain wall assemblies. A qualified local contractor can assess your specific home and recommend the best approach.
Can spray foam insulation help reduce my AC bills in Conroe?
Yes — significantly. Air conditioning accounts for the majority of energy costs in hot climates like Conroe, TX. Spray foam seals all gaps and cracks that allow conditioned air to escape, which is the primary cause of high AC bills. Most homeowners in hot climates report 20–30% reductions in cooling costs after spray foam installation.
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.
