Roof leaks, stucco failures, siding defects, window leaks, and foundation water intrusion repair for residential and commercial properties across the San Francisco Bay Area.
Water Intrusion & Waterproofing Services
Wood Siding & Dry Rot
The San Francisco Bay Area's coastal fog and driving winter rains destroy exterior wood. We specialize in locating trapped moisture, replacing structural dry rot, and properly waterproofing wood siding, fascia, and eaves.
Window & Door Leak Retrofitting
A leaking window is rarely just a caulking issue—it's a flashing failure. We safely remove exterior trims, repair hidden wall rot, and install modern weather-resistant flashing systems so your windows never leak again.
Stucco Water Intrusion
When stucco cracks or lacks a proper weep screed, it absorbs water like a sponge. We trace stucco leaks to their source, repair the building paper underneath, and seal the envelope to protect your framing.
Roof & Flashing Leaks
Most wall leaks actually start at the roofline. We diagnose and repair failed kick-out flashing, damaged drip edges, and complex roof-to-wall intersections where water forces its way into your home.
Foundation Leaks
From hillside homes in Marin to flat lots in the Peninsula, hydrostatic pressure pushes water through foundation walls. We seal structural cracks, stop slab leaks, and restore your home's lower envelope.
Deck & Balcony Leaks
Elevated decks and balconies are notorious for trapping water and leaking into the rooms below. We repair failed deck coatings, rotted joists, and improper sliding door pans to ensure your walkable surfaces are completely watertight.
Building Envelope & Moisture Control Experts
Most contractors guess. We use building science to pinpoint exactly where the water is breaching your exterior envelope.
Visual & Thermal Inspection
We start with high-resolution thermal imaging and moisture meters. This allows us to “see” trapped moisture behind your stucco, wood siding, and drywall without tearing open your walls.
Targeted Water Testing
Water travels in unpredictable ways in aging Bay Area homes. We isolate windows, roof flashing, and foundation seams using controlled spray racks to recreate rain and identify the exact point of failure.
Forensic Diagnosis & Planning
We don’t do exploratory demolition. Once the leak is verified, we provide a detailed forensic plan mapping out the exact entry point, the extent of hidden dry rot, and the specific steps required to fix it.
Permanent Envelope Repair
With the source identified, we surgically remove damaged materials. We replace the structural dry rot, install proper weather-resistant barriers, and seamlessly match your existing exterior finish.
Why Choose Us
We Are Waterproofing Envelope Specialists
When water is destroying your home, a tube of caulk won’t save you. General contractors and handymen treat the symptom by painting over water stains or patching drywall. We treat the disease.
- We Don't Do Remodels: We aren't distracted by building kitchens or adding bathrooms. 100% of our focus and training is dedicated to exterior water intrusion and structural rot.
- No "Band-Aid" Fixes: We don't just seal over the problem. We track the leak to its absolute source, whether it's a failed weep screed, hidden roof flashing, or a cracked foundation.
- Bay Area Climate Experts: We build our repairs to specifically withstand San Francisco's coastal fog, harsh marine layers, and intense winter atmospheric rivers.
- Permanent Structural Restoration: We don't just stop the water; we replace the hidden dry rot and compromised framing to ensure your home's structural integrity is fully restored.
Transparent, Fair Pricing
We do thorough leak inspections before any work begins so you can feel confident about the price you’re given—no hidden fees, upsells, or last-minute surprises. The only time your quote will ever change is if you request additional work. Our goal is simple: deliver exceptional value, honest service, and total peace of mind from start to finish.
Continuous Progress Until Completion
Once we start your project, we stay until it’s done. We don’t disappear for days or bounce between job sites. (We only pause for Sundays or poor Bay Area weather.) You’ll never be asked to wait for progress—we stay on-site until your exterior envelope is completely restored.
Personalized Project Management
You’ll never be left in the dark. We manage each project directly, guaranteeing you always have immediate access to updates and answers. No long hold times. No chasing down subcontractors. What we promise is exactly what we deliver: clear communication and consistent accountability from start to finish.
Expert Craftsmanship
Every repair is performed by a specialist. Our foundation leaks are fixed by concrete experts. Our roof-to-wall transitions are completed by professional roofers. We don’t believe in “jack of all trades, master of none.” Instead, we use highly trained tradesmen with deep expertise in their specific field, ensuring lasting quality and top-tier workmanship on every project.

Frequently Asked Questions
Yes. When water is entering your home, time is critical. We offer fast response times for emergency leak diagnostics, especially for sudden roof flashing failures, structural water intrusion, and siding breaches during Bay Area storms. Contact us immediately to get prioritized assistance.
Because water intrusion is complex and often hidden behind stucco or siding, a quick visual “guess” is rarely accurate and usually leads to surprise costs later. Instead, we offer a dedicated Leak Diagnostic Assessment. We use thermal imaging and targeted water testing to pinpoint the exact failure point. Once we know the true source, we provide a firm, transparent quote for the permanent repair with zero hidden fees.
Because water travels in unpredictable ways, prices vary based on the scope of the hidden damage and the materials required to fix it permanently. However, we will always conduct a thorough inspection first to find the exact source of the leak. Once we know the true scope, we give you a clear, upfront quote before we begin any work—no hidden fees or surprises.
Yes. Because we specialize entirely in the exterior envelope (roofs, walls, windows, and foundations), almost all of our work takes place on the outside of your house. You can remain at home safely and comfortably. We maintain clean, organized job sites and communicate clearly every step of the way to ensure your daily life is minimally disrupted.
