Insulation Company in Menlo Park, CA
Woolsey Attic Insulation is the insulation company Menlo Park homeowners call when they want a written price before any work starts and a guarantee that actually means something. We handle attic insulation and spray foam insulation only, and we’ve built our reputation on showing up when we say we will, leaving the job site cleaner than we found it, and standing behind every installation for 365 days in writing. If your Menlo Park home has drafty rooms, uneven temperatures, or energy bills that climb every summer, call (669) 333-3579 and we’ll walk you through what’s actually going on in your attic.
Why Menlo Park Homes Are Different
Menlo Park’s post-war ranch homes, particularly in the Willows and Suburban Park neighborhoods, often lack adequate insulation due to original minimal fiberglass batts and poor air sealing. Many of these 1950s and 60s houses went up when energy was cheap and building codes asked far less of a wall or ceiling. The result is an attic that lets conditioned air escape all year, which stings more than usual in PG&E’s high-rate territory. Add in Menlo Park’s mild marine climate with cool, foggy summers and damp winters, and the job becomes about more than stuffing material into a ceiling. Moisture management, ventilation, and vapor control matter as much as R-value here. We see this daily in neighborhoods like Belle Haven, where some homes still have original rockwool or no wall insulation at all, and drilling and blowing cellulose from the exterior is the standard retrofit. It’s detailed work, and it’s exactly the kind of job where a written guarantee protects you.
Our Main Menlo Park Services
These are the two insulation services Menlo Park homeowners ask us about most often. Each has its own detailed page with pricing, what the job involves, and answers to common questions.
Attic Insulation in Menlo Park
Most Menlo Park attics we see are under-insulated by today’s standards. Older ranch homes in the Willows and Suburban Park often have a thin layer of fiberglass batts that settled decades ago, leaving R-values in the teens when current recommendations sit at R-38 or higher. Our Attic Insulation in Menlo Park page walks through air sealing, blown-in options, and what it takes to fix the problem for good. We inspect what’s up there, give you a written price, and never push material that doesn’t fit the house. In Menlo Park’s damp winters, proper ventilation matters as much as the insulation itself, and we account for it on every job.

Spray Foam Insulation in Menlo Park
Spray foam insulation, a two-part liquid that expands on contact and seals gaps airtight, solves a specific Menlo Park problem: older homes with odd framing, recessed lights, and gaps that fiberglass simply can’t fill. In West Menlo Park’s newer luxury homes, we see a different issue: thermal bridging through framing that open-cell spray foam can address. Our Spray Foam Insulation in Menlo Park page explains open-cell versus closed-cell, where each makes sense, and what to expect during installation. It’s the right call for some homes and the wrong call for others, and we’ll tell you which one yours is.
