With Home Insulation, It's Important To Do It Right

February 28, 2017

For homeowners contemplating new insulation, it's important to get it done right the first time. And choosing the right contractor is key to success. Today, there are many insulation companies out there, each peddling their products and their services. What's important for a homeowner is to do some research prior to making a final decision. This is especially important if spray foam insulation is involved - it's highly specialized and requires a good deal of industry experience. With home insulation, regardless of product, installation has to be professional - anything short could set the stage for costly re-installation and a stressful stretch of time. The thing is, it's not good enough for a local contractor to simply promise installation results. The product choice has to be right for the job, the installation has to be to code, and the finished work must be somehow guaranteed. Otherwise, there isn't any company assurance of long-term project performance. Good contractors have in-depth product knowledge, along with veritable installation experience, particularly with specialty insulation products. A good contractor will also stand behind all of the work with a customer satisfaction commitment - a money-back promise; a product warranty; and a company satisfaction warranty. Doing the extra homework when choosing a reliable insulation contractor will pay off for the homeowner, with better short term and long term outcomes. Unfortunately, with spray foam insulation, there are too many disappointments, mostly because of substandard workmanship. Shopping around for price alone can turn out to be risky, simply because spray foam cannot endure a second-rate install. Having to deal with a deficient install means having to remove and reinstall the insulation. And with spray foam, this could entail costly work in order to remedy the situation. The solution: doing it all right the first time around. Spray foam insulation demands experience and expertise. Professionals are trained to work with the chemical compounds, and are proficient with the intricacies of the installation. Clearly, it's the quality of an installation that will guaranty maximum performance for the product installed. Here again, spray foam is demanding - there is no way to ensure peak performance without ensuring superior installation. For that matter, a quality approach to installation applies to all products. Whatever the insulation product, professional installers do it right - they follow the construction code and they install everything according to the specifications. As it is, it's up to the homeowner to choose a contractor who will operate accordingly. It's all about being informed, so that astute project decisions can be made during the life of a project. Better-informed consumers also work more constructively with their contractor, making sure that their project needs are satisfied. Insulation is one of the better home improvement projects that a homeowner can undertake. The real question is: why not do it right the first time? With a professional, an installation should last for years, and provide long lasting performance. Best of all, the energy savings with high quality insulation can often pay off the initial project investment in very short order.
