The service
What wall insulation retrofit is, what a visit covers and where the line is.
The short answer
Wall insulation retrofit adds insulation to finished walls that have little or none. Wall Insulation Retrofit in Los Gatos is booked through pros who cover its 4 ZIP codes, in neighborhoods such as Downtown Los Gatos, Almond Grove, and Belgatos. In Los Gatos, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. On NorTech the independent pro you choose sets the price and warranty for this work.

What is not part of wall insulation retrofit
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Any job where labor and materials together reach $1,000 or more. That is licensed-contractor territory, and NorTech points it out before booking.
- Electrical repairs, including replacing old knob-and-tube wiring. That is a licensed electrician and must be done first.

- Repainting patched walls beyond a prime coat.

Before you book wall insulation retrofit
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Check for cold walls and drafts first
On a cold or hot day, feel exterior walls and outlets for temperature and drafts. Note rooms that are hard to heat or cool.
Photograph the exterior and attic
Photos of the siding, the attic floor and any leaks help pros plan the method, including which walls to open and where the cavities may be blocked.
Fix leaks before insulating
Water coming through siding, windows or roof should be repaired first. Insulating a wet wall holds moisture and invites rot.
Tell the pro about your wiring
Let the pro know if you have old cloth-covered or knob-and-tube wiring. A licensed electrician should assess it before the cavity is filled.
Decide which side gets opened
Ask whether holes come through the siding or the interior, and choose the repair you are more comfortable with.
Ask how coverage is checked
Ask how the pro confirms every cavity is full, for example with a thermal camera or a probe, and what they do with blocked cavities.
Say where in Los Gatos you are
Add your neighborhood, for example Downtown Los Gatos, Almond Grove, and Belgatos, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.
