Your Home Insulation Needs — In Trusted Hands Since 1956

W H Davis Insulation specializes in insulation work for residential and historic renovations. We provide trained installers who inspect the attic areas for problems before the material is installed. Special attention is given to correct airflow and the proper amount of attic ventilation to help reduce your energy costs. We make every effort to provide a quality job at an affordable price. But don’t take it from us... read what your neighbors are saying? 

Before insulating any project, we complete a thorough inspection of the area to check for water leaks, pipe jack connections, drain vents connections, electrical and recessed light box covers and chimney penetrations: 

  1. Calculations — we ensure that your attic has the proper amount of ventilation within the soffit areas and the roof
  2. Interior Soffit Ventilation System — to allow your attic to breathe properly to maintain efficiency
  3. Duct Wrap Insulation Solutions
  4. Professional Attic and Wall Insulation — blown in from the exterior or interior through brick walls, plaster walls, or drywall. Fiberglass or cellulose options available
  5. Free Energy Home Inspections and Analysis
