Why Brentwood Property Owners Trust IronNest
Brentwood is a rapidly growing East Bay community on the eastern edge of Contra Costa County, with a large supply of relatively affordable single-family homes that owners are actively upgrading. We serve Brentwood with kitchen and bathroom remodels, ADU construction, siding, and exterior painting — all permitted through the City of Brentwood Building Division.
Brentwood's newer housing stock (most built 1990s–2010s) is reaching the point where first-generation kitchens and bathrooms are getting their first real update. We help Brentwood homeowners improve their homes' value and livability on a realistic budget.

Painting in Brentwood
Interior & Exterior Painting
A fresh coat of paint is one of the highest-ROI improvements you can make to any property. We don't just roll paint — we prep surfaces properly, repair cracks and damaged drywall, apply primer where needed, and use quality materials rated for California conditions.

- Victorian color consultation for historic homes
- Commercial repaints scheduled after hours to minimize disruption
- Exterior paint rated for California coastal and valley conditions
Siding in Brentwood
Siding Replacement & Installation
Old siding loses its seal, lets moisture in, and drives up heating bills. We replace deteriorated wood siding, install fiber cement products like HardiePlank, and handle all trim, flashing, and caulking so nothing comes back later.
- James Hardie certified installers
- Wood, fiber cement, and engineered wood options
- Complete moisture barrier installation — no shortcuts
- Matching existing profiles on historic homes where possible

Stucco Repair in Brentwood
Stucco Repair, Recoat & Restoration
Stucco is everywhere in Bay Area construction, and it fails in predictable ways — cracks at windows and corners, moisture intrusion behind the face, efflorescence, and delamination. We repair stucco correctly: addressing the moisture source first, then patching and recoating so repairs don't crack back open within a year.
- Root cause analysis before any patching — no surface-only repairs
- Three-coat traditional stucco application for major repairs
- Elastomeric coating options for older stucco with minor checking
- Color matching to existing stucco — integral pigment mixed on site
- Flashing and waterproofing at all penetrations and transitions
Foundation Repair in Brentwood
Foundation Repair & Seismic Retrofit
Foundation issues in the Bay Area are common and serious. We handle pier underpinning for settling foundations, cripple wall and crawl space seismic retrofits, slab crack repair, and drainage solutions that stop ongoing movement. Every foundation job starts with an honest assessment — we won't oversell you on work you don't need.
- Seismic retrofit for cripple wall foundations — FEMA P-1100 compliant
- Pier underpinning for settling or undermined foundations
- Crack repair with epoxy injection and carbon fiber straps
- Drainage and waterproofing to stop hydrostatic pressure
- Structural engineering coordination on every project
Concrete Work in Brentwood
Driveways, Patios, Walkways & Foundations
We pour and finish concrete for driveways, patios, walkways, retaining walls, and foundations. We also repair settling, cracked, and spalled concrete surfaces. Proper subgrade prep, correct mix design, and control joints — these are the details that make concrete last 30 years instead of 8.
- Subgrade compaction and base preparation — the foundation under the concrete
- Correct mix design for application — 3,000 to 4,500 PSI as needed
- Control joint placement to prevent random cracking
- Broom, exposed aggregate, stamped, and salt-finish options
- Drainage integration — surface slope and catch basins where needed
Deck Construction in Brentwood
Decks, Patios & Outdoor Living
A well-built deck adds usable square footage, improves how you use your property, and increases resale value. We build wood, composite, and Trex decks — handling structural design, permits, ledger waterproofing, and all finish work. In the Bay Area, a deck that's not properly waterproofed and anchored doesn't last.
