"Why West County Insulation is the Best Choice for Your Insulation Needs When it comes to insulation, quality and professionalism matter—and that's exactly what I received from West County Insulation. Fast and Knowledgeable Service Brandon, who provided the initial quote, was timely, knowledgeable, and thorough. He explained all my options and made sure I understood everything clearly, giving me confidence in my decision. Professional and Efficient Installation The installation team, led by Andrew and Isaac, was efficient and professional. They used drop cloths to protect my home and completed the job quickly without sacrificing quality. The owner even took the time to check in after hearing about a fall I had during the job—demonstrating the company’s commitment to customer care. Great Quality at a Fair Price The insulation quality is excellent, and my home is already feeling more comfortable.

iFOAM is a U.S.-based insulation franchise fueled by the franchising experts at HorsePower Brands. We specialize in spray foam insulation and also provide best-in-industry blown-in solutions, insulation removal, retrofitting and other specialty project services. At iFOAM, we saw an issue with the industry—a lack of quality and trustworthy services and a clear absence of certified training when it came to spray foam. At iFOAM, we’re flipping the script by providing our certified technicians with the best tools, training and products in the trade and bolstering your experience with prompt, timely communication.

At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

"Professional, timely and best installers we’ve had. Our installers took to time to get everything fit right. They had their hands full with a few doors and windows, due to bad framing from our construction contractor. Our new doors and windows work flawlessly now."

"Arrived on time as scheduled. They covered floors and railings with commercial moving blankets to protect floors and railings and did all necessary prep work and inspection in attic. Once all prep work complete, they started adding insulation. When all work was done they cleaned up everything and could not tell they were there other than the second floor was now much cooler. Will definitely recommend."

Insulation questions, answered by experts

Choose affordable materials for a cost-effective insulation installation (say that five times fast). The most affordable insulation for your garage is fiberglass. Fiberglass comes in batts or rolls and is relatively easy to install compared to other types of insulation. You can also install this insulation without needing to drywall over it, which can cut down costs.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.
