Estimating house insulation cost


How much does it cost to insulate a house?

Cost to insulate a house determined by number of factors and total expenses primary depend on insulation prices and labor cost to complete the work. While calculating total expenditures for installing insulation number of additional factors should be taken into account. Contractor will calculate the cost after in-home inspection, determining type of insulation for ceiling and walls application and analyzing work complexity. Itemized estimate will reflect all charges and fees associated with the insulating process, as well as materials expenses which have to be purchased to complete the project successfully.

Available in stock at local home improvement retailers fiberglass roll or batt insulation with R13 – R60 thermal performance and can be used for 2” x 4” or 2” x 6” wood or metal frame walls as well as ceiling is one of the most affordable options. Blow-in insulation is not an expensive product as well. Closed cells spray foam insulation tends to have highest price, but it is the most effective insulating material available which not only thermal efficient but absorb sound and resist water as well.

Determining labor cost for insulation installation labor-cost

Installation of fiberglass batts or rolls will be estimated at minimum charge. There are not much tools or equipment required for completing such task and because of work simplicity labor with minimum construction skills can be hired. Cost of labor will increase for applying blow-in insulation. Spaying foam will be priced at much higher rates.

Shopping for insulation shopping

Insulation should be purchased according to a geographic location. In colder climate it is recommended to use insulation with higher thermal resistance for better insulating effectiveness. Fiberglass insulation which sold in rolls with 31 – 48 sq ft coverage area each can be purchased at nearly any local home improvement store. Bigger building suppliers normally have in stock blow-in cellulose insulation and rigid foam or polystyrene sheets 4 feet wide and 8 feet long.

Estimating installation time estimating-time

Normally 7 – 8 hours will be sufficient for a crew of four professional installers to complete insulation of exterior walls and ceiling in a three bedroom 1,900 – 2,300 square feet one story house. But depending on house design, size and type of insulation the process might take longer.

Work complexity work-complexity

Difficulty of work will depend on a type of insulation and application method. Many handy homeowners can easily manage installation of insulation bought as pre-cut batts, rolls, or rigid panels.

Blow-in fiber insulation should be applied using a blowing machine. Typically very low percent of homeowners consider cutting labor expenses and complete such task themselves.

For insulating the house with polystyrene or polyurethane spray-applied foam insulation special equipment should be used for mixing chemicals which create close or open cell foam as well as spraying requires some construction skills and experience. It is normally not a do it yourself project and a professional contractor should be hired to complete such work.
