What Sunnyvale’s housing means for repairs
Sunnyvale's median home value is about $1.8 million, and the median home dates to 1976. About 22% of homes predate 1960, and about 20% were built since 2000. Only about 36% of homes are single-family detached, and about 44% are owner occupied, with many apartments and townhomes.
The city has one of the largest concentrations of Eichler homes, built in the 1950s and 1960s with post-and-beam framing, flat or low roofs, walls of glass and radiant heating pipes in the slab. Those homes need roof coatings, single-pane glass upgrades and radiant leak repairs. About 6% of homes are in mobile home parks, and about 52% heat with gas. Older ranch homes have original panels and copper or galvanized lines.
Weather that wears on Sunnyvale homes
Sunnyvale has a mild climate with dry summers and cool, wet winters. Heavy winter storms test flat and low-slope roofs, especially on Eichlers. The city sits between the San Andreas and Hayward faults, so foundation bolting and water heater strapping matter. Soils near the bay include expansive clay that moves slabs and patios. Summer heat waves are short but push homes without AC to add heat pumps. Hard local water leaves scale in water heaters and fixtures, and dry summers let small roof and caulk gaps go unnoticed until the first storm.

Seasonal checklist
- Fall
- Recoat and clear drains on flat roofs before winter rain.
- Winter
- Watch for warm spots on floors or rising boiler pressure, signs of a radiant leak.
- Summer
- Check that the water heater is strapped and gas lines have flexible connectors.
Common questions
- How do I know if my Sunnyvale Eichler has a radiant heat leak?
Signs include warm or damp spots on the floor, a boiler that keeps losing pressure, or rising water bills. A specialist can pressure test the loops. Many owners abandon the old slab loops and switch to a new heating system.
- Can Runhome help with a home in a Sunnyvale mobile home park?
Yes. Describe the skirting, roof, plumbing or floor problem or send photos, and Runhome builds an estimate. It then calls local contractors who work on manufactured homes and collects quotes.
- Why do repairs on older Sunnyvale homes cost what they do?
Labor in the Bay Area is expensive, and older homes often need upgrades to meet current code when work is done. Eichlers need specialists for radiant heat and flat roofs. Runhome bases estimates on real contractor pricing.
