Insulation Company in Kentfield, CA
Attic insulation, blown-in insulation, and insulation removal in Kentfield, CA each come with their own set of local conditions. The homes here skew older than most of Marin’s newer developments, summers run hot and dry, and many properties sit on shaded, sloping lots where attic ventilation gets compromised by tree canopy. We approach every Kentfield job the same way: a written price before any work starts, background-checked technicians on site, and a 365-day written guarantee on the install. Call (254) 272-5876 for a free estimate.
Why Kentfield Homes Are Different
Kentfield’s housing stock was largely built between the 1950s and 1970s, which means most attics were insulated to R-19 or R-30 at best when today’s target for Marin County runs R-38 to R-60. Many of those original fiberglass batts have compressed to a fraction of their rated R-value. Add in the summer heat that radiates through roofs in July and August, and the difference between adequate and insufficient attic insulation shows up directly in cooling costs.
The terrain matters too. Homes along Sir Francis Drake Boulevard and up in the hillside neighborhoods off College Avenue sit on heavily wooded lots. That’s beautiful, but the tree canopy blocks roof ventilation, holds moisture against rooflines, and slows drying after the fall rains. We regularly find attics in Kentfield where insulation has settled or been damaged by rodents and roof leaks, and the homeowner only discovers it after a heat wave or a cold snap drives the energy bill up. Older Kentfield homes also tend to have smaller attic access hatches and tighter joist spacing, which changes how we approach blown-in coverage. These aren’t generic tract homes, and the insulation work shouldn’t be treated as generic either. Bryce Holloway oversees every Kentfield job so the details don’t get missed.
Our Main Kentfield Services
Most Kentfield homeowners call us first for attic insulation or blown-in insulation. Both are covered below, along with insulation removal for older homes that need the existing material taken out before new material goes in.
Attic Insulation in Kentfield
Older Kentfield homes often have fiberglass batts that were installed decades ago and have since compressed, shifted, or been chewed through by rodents that are common in this area’s wooded lots. Our Attic Insulation in Kentfield work starts with an inspection of the existing R-value, then a plan to bring the attic up to a level that actually holds the heat out in summer and keeps it in during the cool, damp Marin winters. We install fiberglass and mineral wool from Owens Corning and Rockwool, among others.
Blown In Insulation in Kentfield
Kentfield attics with irregular joist spacing, low clearance, or lots of cross-bracing are good candidates for Blown In Insulation in Kentfield. The material fills gaps and voids that batts can’t reach, which helps with the small air leaks that drive heat loss. For homes on shaded hillside lots, we also check that the blown-in material won’t block soffit vents, which is important on this terrain where roof-over-deck ventilation issues are more common.
Insulation Removal in Kentfield
If your Kentfield attic has old insulation that’s water-damaged, contaminated by rodent activity, or simply too thin to do its job, Insulation Removal in Kentfield is the right first step. We remove the existing material, clean the attic space, and then recommend what goes back in, whether that’s new batts or blown-in. Homes near Corte Madera Creek and in the lower, flatter parts of Kentfield tend to see more moisture-related insulation damage than hillside properties.
