 Trustindex verifies that the original source of the review is Google. We had Amira upgrade our attic insulation to help with our top floor being consistently much warmer than the rest of the house in the summer.  They were communicative, friendly, made good recommendations, and delivered great quality work on schedule.  I was especially impressed with how coordinated their crew is.

When I first called and spoke to Yasemin, after I gave her my address, she realized that they were already finishing up another estimate close by, and she reached out to see if they had availability to drop by and look at my attic right then.  Mo was in my attic evaluating it within 15 minutes of when I first called - he got here faster than I got to the hospital when my wife was in labor.  It's partially luck that he was nearby, but for them to realize that my address was nearby and jump on that opportunity tells you exactly how coordinated, flexible, and committed to good service they are.  When you hire these people to work on your project, you're NOT doing business with a soulless corporation that treats you like a number.  You're doing business with real humans who take pride in their work and care about understanding your needs and delivering good solutions to your problems.  I'd hire them again in a heartbeat.

 Trustindex verifies that the original source of the review is Google. I’m a General Contractor. It’s important that my clients receive the highest quality work which is why we now exclusively use Amira for our insulation. My experience with them is that they’re always professional, thorough, highly reliable and leave a clean job site. We’ve used them for open and closed cell spray foam, batts, and blown in insulation. Good experience across the board. I’m very glad that we linked up with Amira Contracting to handle our insulation work.

 Trustindex verifies that the original source of the review is Google. I had my pole barn in townsend, which is gonna be used as my shop insulated with closed cell spray foam by Amira contracting and I couldn’t be more pleased with the end results. I was initially thinking to cover up the walls, but when I seen how nice they made it look I decided to just paint the foam and I will gladly have that be my finished surface. Mo is a man of his word. They did a thorough job, they were nice and pleasant and their cleanliness left me nothing but happy. I will be telling my friends.

 Trustindex verifies that the original source of the review is Google. From the estimate through the completion of my crawlspace insulation job, Amira was professional and a great company to work with. If you need your crawlspace insulated, the product they sell and install is the best. Their prices are very fair as well.

 Trustindex verifies that the original source of the review is Google. Mo was terrific to work with from start to finish. He was extremely knowledgeable and took the time to understand our specific needs right away. What stood out most was his honesty and professionalism — he clearly explained the scope of work, outlined our options without overselling, and set realistic expectations.

Throughout the project, Mo demonstrated exceptional dedication, efficiency, and attention to detail. His workmanship was thorough, and it was clear he takes great pride in doing the job right. We were very impressed with both the process and the results.

We highly recommend Mo and his team for any insulation needs — you’ll be in excellent hands. We could unfortunately just give him five stars, but in our opinion, he was a 10 star performer!!!!

 Trustindex verifies that the original source of the review is Google. If you are looking for a local, family owned business you cannot go wrong with Mo. I've worked with him on quite a few projects now as a professional drywall/painter and it's always nice showing up to the project after Mo has completed his part of the job and hearing the home owners ALSO express how happy they were with their entire experience using AMIRA.
All around great people 🙌🏼

 Trustindex verifies that the original source of the review is Google. Amira Contracting is truly a clean and professional team. Scheduling was quick, and they showed up right on time. After the spray foam insulation, the difference in the room is huge, especially in the summer heat. Even other contractors who saw the work gave compliments. The performance is so good that it definitely feels worth doing the same for the garage as well.

Why New Castle County Homes and Buildings Need Better Insulation

New Castle County is home to a wide range of properties, from historic homes in Wilmington and Newark to growing communities in Middletown, Bear, and Townsend. With such a diverse mix of homes, businesses, warehouses, and commercial buildings, insulation needs can vary significantly from one property to the next.

Many homes were built before modern energy-efficiency standards, while even newer construction can experience drafts, uneven temperatures, moisture issues, and high utility bills when air sealing and insulation are not properly addressed. Properties near the Delaware River, Christina River, and Delaware Bay often face additional challenges from humidity, wind, and seasonal weather changes.

That’s where the right insulation system makes a difference.

Spray foam insulation is one of the most effective solutions because it insulates and air seals at the same time, helping improve comfort, energy efficiency, and moisture control. Depending on the project, we may also recommend blown-in insulation, fiberglass batts, mineral wool, or a combination of materials to achieve the best results.

Amira Contracting proudly serves homeowners, builders, and businesses throughout Wilmington, Newark, Middletown, Bear, Hockessin, and the surrounding New Castle County area. Whether you’re building new, upgrading an older home, or improving the performance of a commercial property, our team can help you choose the right insulation solution.

Frequently Asked Questions — New Castle County Insulation

Do older farmhouses in New Castle County require a different approach to insulation?

Often, yes. Many older New Castle County homes were built with balloon framing or have had additions over the years that create complex wall and attic assemblies. Spray foam is particularly well suited for these situations because it conforms to irregular shapes and seals gaps that batt or blown-in insulation might leave exposed. We assess each home individually and recommend what actually makes sense for the structure.

Can you insulate a pole barn or agricultural building in New Castle County?

Absolutely — it’s one of the most common projects we do in this area. Closed-cell spray foam is ideal for pole barns and metal buildings because it adheres directly to the steel and won’t leave gaps. It also adds structural rigidity to the walls and roof panels. Whether you’re converting a barn for year-round use or just trying to keep equipment from sweating, we can help.

How long does a spray foam insulation job typically take?

Most residential jobs are completed in a single day. Larger commercial or agricultural projects may take two to three days depending on the scope. We’ll give you a realistic timeline upfront when we provide your estimate.

Do I need to be home during the installation?

You don’t need to be present for the entire job, but we do ask that someone is available at the start so we can walk through the space together and confirm the scope. After that, our crew handles everything.
