The TLS team did a great job at providing an estimate, scheduling, and sending a text message before their arrival. They provided photos before and after to let me see how everything looks, meeting the requirements and level I selected. I recommend them and would use them again if needed.

Mike Moly★★★★★9 months ago

I'm fully satisfied with the service. Got the attic insulated with blow-in insulation. The guys made photos before and after putting the insulation, used rulers to be sure that thickness is sufficient. Cleaned up afterwards. Provided very professional and neat service

I called three companies for quotes on insulation and this was the only company that returned my call the same day and gave me a quote the same day. The other company never called me back. They scheduled to come out the next week and the workers were great in communicating when they were planning to arrive. The workers was very polite and worked quickly, but thoroughly. Very happy with this company and would recommend it to my friends and family.

I have a 1972 2,500 sq. Ft. house that was in dire need of insulation in the attic space, TLS came to the rescue with a timely quote and good explanation of what they could do. The quote also contained all the necessary discounts that could be obtained from the power company (in this case FPL). 10 days after the quote, TLS installed the insulation, took around 2 to 3 hours, took before and after photos, cleaned up an left. Very efficient operation.

Janet Gerth★★★★★11 months ago

We needed more insulation and a neighbor recommended TLS. The first employee came out and explained everything to us. Gave us an estimate and we agreed. A lot less than we thought it would be. Put on the schedule and the two workers were very personable and professional. Showed us camera pictures of the attic and how much improved it was. We highly recommend this company!!

Annie F★★★★★a year ago

TLS and their team was so great to work with. They were very helpful and informative from the very first phone call. They called and rescheduled due to the hurricane but kept me informed with text messages and emails. They arrived little earlier than scheduled which actually worked out great for me. I’m glad they were on time and not late! The installation gus were so friendly and did a great job! Very trustworthy company! I will highly recommend TLS to all my friends and family. Great job!!!

Super excellent. These days it is by no means any guarantee that you’re going to get people who know what they’re doing and care about their job. This company ,from the initial contact through today with the job completed has been flawless. They showed me what needed to be done ; and I was definitely barren in some spots in my attic for insulation. Today they came first thing in the morning and very efficiently topped it up. Hats off to Shane and Cody! Great doing business with you !

Yamile008★★★★★a year ago

They were great. Answered my call immediately and schedule an appointment for an estimate. They arrived on time, emailed me the estimate right away and were able to schedule the job within a week. They were professional and everyone I spoke to and came to the house to do the work knew what they were doing. They were efficient and cleaned up any loose insulations bits from the floor of the garage before they left. I appreciate that everyone from the person who took my call, came out for the estimate and did the installation, communicated with each other so everyone was on the same page about the job and what needed to be done. Super efficient and professional. I definitely recommend them.

I can already feel a difference in temperature in my garage! Alex got me on the schedule quickly from my first call. The service time was about 30 mins, it was quick and no mess left behind. Great customer service also!

debbie kent★★★★★4 months ago

Great service (and cleanup) by Alex. I don’t have a lot of attic space over the 2nd floor but the old insulation was 23 years old. I figured it was time to refresh what was there. Alex checked the AC vents to ensure there were no leaks and then blew in wool insulation to every inch of the attic space. Thank you Alex - from the first phone call to your vacuuming my floor!

Brian King★★★★★7 months ago

Brrrr! Great experience all around, from the first phone call to installation and clean up. Alex inspected and provided feedback for my installation. I chose blown in insulation and it made an immediate impact in my 18 year old home. This is an easy, cost effective investment that will make a big difference in my home this summer!

We contacted them after hurricane Milton and they came out immediately and their team was incredibly polite and professional! Our entire ridge vent blew off of our roof during the hurricane and they were sympathetic and quick to get the job done! They did not only an amazing job, but cleaned everything up and were super fair on price! Joe came out to inspect the job while they were still here and to ensure that we were happy! I will continue to recommend them!

This is a business w/ integrity. Came out for an estimate and I was ready to spend up to $2K, but was told my insulation is in good shape, could last another 7 years, and they gave me additional energy saving tips. They could have gotten a sale, but they are an honest business.

Was recommended by a neighbor. Called multiple times- no showed on my appointments twice and then came by and either lost our quote and just didn’t care to send it. Called twice to figure out what was going on and never heard back. I do not have time to chase down a company that clearly doesn’t want business. Woman answering office didn’t seem to care either.

Frequently Asked Questions — Spray Foam Insulation in St. Petersburg

These are the questions St. Petersburg homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 30% typical energy savings. Compare the 15 verified St. Petersburg contractors above for exact quotes.

Is spray foam insulation a good choice in hot and humid climates like St. Petersburg?▼
Absolutely. Hot and humid climates like St. Petersburg, FL 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 FL 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 St. Petersburg?▼
In hot and humid climates like St. Petersburg, FL, 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 St. Petersburg?▼
Yes — significantly. Air conditioning accounts for the majority of energy costs in hot climates like St. Petersburg, FL. 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 in St. Petersburg, FL?▼
In St. Petersburg, FL 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 St. Petersburg costs $2,000–$6,000. Most St. Petersburg 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 St. Petersburg, FL?▼
When searching for a spray foam contractor in St. Petersburg, FL, 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 St. Petersburg 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 St. Petersburg 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.
