Is it time for a complete overhaul? Let Larson Builders be your contractor from the roof to a deck and everything in between. We do it all. This homeowner not only has the best looking house on the block, they would also qualify for an Energy Tax Credit, with the addition of energy efficient windows, air conditioner, and improvements to house under the siding. Larson Builders used Dow Housewrap and foam sheathing under the siding to improve the R-Value (the rating of air filtration through the walls), with a higher R-Value you will use your furnace and air conditioner less because the weather outside cannot seep through the walls as easily.
