Your house will be worth more and eaiser to sell if you Retro Fit Today!

Many people put off making energy efficienct upgrades becasue they want to pass the buck to the next guy... how foolish. According to the appraisers journal for every 1 dollar saved per year in energy projects you will gain $20 dollars in the value of the house. Ie. $ 500 annual savings= $10,000 increased property value and yes your house will be easier to sell now becuase it is more comforatable and safer than the rest of the market.  

Spray Foam

Spray foam does what other insulation materials can't. It's a real problem-solver. Homeowners benefit from this product's very high R-value, its ability to bond directly to bare wood and the way it molds itself around any obstacle. Spray foam is the perfect choice for any project that has an open wall, floor or ceiling cavity.

Attics and Crawlspaces

A complete thermal envelope separates every conditioned interior space of your home from outdoor and unconditioned spaces (such as your crawlspace and attic) with a layer of insulation. Every thermal envelope is different. RetroGreen Energy assigns a BPI-certified professional to design and define the ideal thermal envelope for every home.
