Caleb is very friendly and easy to work with. He worked with me when a scheduling conflict came up and the job needed to be postponed. The first job was filling a gap where my front steps had sunken. I'm very happy with the job he did. The other was grinding a sidewalk that had heaved and I wanted to avoid a tripping hazard. I'm very satisfied and will use Caleb again for small concrete repairs.

Exceptional Service and Quality Work! Caleb - DeFord Spray Foam & Concrete Lifting did a fantastic job leveling various areas in our driveway and porch steps. Caleb is easy to work with and couldn’t be happier with the results! Caleb is very knowledgeable and took the time to explain the process to ensure we knew what to expect. Thanks Caleb!!

Colleen Carlson★★★★★a month ago

Caleb repaired our sidewalk and driveway with their concrete lifting service. The concrete was so bad that kids would fall off their bikes. They are a family business with the highest integrity and workmanship. We appreciated Caleb's presentation, his work on site, his dedication to every detail and making sure it was correct even when it took more time. After 6 months the concrete lift looks the same as they day they did the work. We had interviewed several companies before choosing Caleb Deford. Not only did he do great work, he was cheaper, and had a down to earth, no pressure, no specials for buying in a few hours presentation.

Called Rod and got a bid, I new it was getting close to being to cold to spray. Rod stopped out measured up the building and we got lucky with the weather and Rod and his crew were here the following Saturday and got it all masked off and sprayed before it was to cold. Its now heated and full of cars. Can't thank Rod and his crew enough for helping me get it insulated before winter.

Adam Johnson★★★★★a year ago

Robert Peterson★★★★★a week ago

I had Josh spray the inside of a 48’ shipping container, TOP NOTCH work & very reasonably priced.

CRJ Properties★★★★★4 years ago

Hands down the best spray foam application I have contracted. Josh is big on relationships and follows through with top of the line product and smart application. The time he spent with me in the planning stage allowed me to rest assured. His vision of what his product can do and what his customer’s end goal is a perfect blend of craftsmanship. Highly recommend.

patrick webb★★★★★4 years ago

I am so happy with the service I received from Diamond Spray Foam. I had Josh spay an older foundation to protect new plumbing and he went above and beyond what I asked of him. His product also added to the structural integrity of the older joists. I even had to reschedule due to an interruption on my end and he couldn’t have been easier to deal with. Quality work from quality people.

South Construction helped remove an attic fan for us and then installed drywall in our ceiling where the fan was. They were extremely professional, attentive and affordable and very respectful of our home the entire time. Their work is phenomenal. I cannot recommend them enough!

Marty Colwell★★★★★2 months ago

I give South Construction & Insulation my highest recommendation for powerwashing and resealing a colored patio project this summer that had some unique caulking removal and replacement matching challenges. From the first contact in making the bid to finishing every detail with high quality work, Justin & his 2 sons were wonderful to work with. So appreciated the great communication & they always arrived within the timeframe he identified each time they came. The end result looked fantastic. And so pleasant & professional to work with. We'll use them again!

John Hotz★★★★★a month ago

Put flooring and doors on my duplex. It now looks like brand new inside. If you need any work done I highly recommend them.

Frequently Asked Questions — Spray Foam Insulation in Waterloo

How much can spray foam insulation save on heating and cooling bills in Waterloo?
Homeowners in mixed climates like Waterloo, IA 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 Waterloo?
For most homes in Waterloo, IA, 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?
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.
