Why Gary Howard
Local knowledge you can't hire twice
Sonoma County soil, drainage and seismic
25+ years of local work means we know how these homes settle and why.
Leveling is our specialty
Most contractors won't lift a house. It's core work for us.
Honest, free inspections
We'll tell you when something is cosmetic and can wait.
Transparent from start to finish
Clear scope, clear pricing, clear timeline — and a call when plans change.
Good to know
Questions homeowners ask
Do I need a free inspection?+
Yes — it's the only way to tell you honestly what's happening under your home. There's no obligation and no pressure afterward.
What are the signs of foundation problems?+
Stair-step cracks in concrete or stucco, sloping or bouncy floors, doors and windows that stick, gaps at trim, and standing water near the foundation.
How long does foundation repair take?+
Crack repair can take a day or two. House leveling typically runs one to two weeks, and a full perimeter foundation replacement three to six weeks. You get a clear timeline before we start.
Do you offer financing?+
We don't finance in-house, but many homeowners use a home equity line or a contractor loan through their bank. We're happy to provide the documentation your lender needs.
What areas do you serve?+
All of Sonoma County, including Sebastopol, Santa Rosa, Petaluma, Windsor, Guerneville, Calistoga, Monte Rio and Camp Meeker. Call us if you're just outside — we may still service your location.
Are you licensed and insured?+
Yes. Gary Howard Construction Co is a licensed California contractor, fully bonded and insured, and BBB accredited with an A- rating as of 2/28/2025.
