WLWC To Perform Tile Deck Leak Investigation on Santa Barbara Estate Home

We’re pleased to announce that we have been retained to perform an investigation on a leaking tiled deck on an estate property in Santa Barbara CA.

A deck at the home has had a history of leaks, leading to damage to ceiling finishes and walls below.

An estate home in Santa Barbara is the subject of our next leak investigation.

The property owner found us after doing a search for a deck waterproofing expert online. We’ll be investigating the leak with visual observations, borescope camera and moisture meters to determine the path of the leak back to its source(s) and write a report after examining the plans, specifications and drawings and comparing the as-built deck to the design intent.

With a history of being able to solve problems and determine responsibility as to what trade may be responsible, our latest client is confident in our abilities to help him recover damages from the appropriate trades that created the defect.

If your building is leaking, call William Leys Waterproofing Consultants LLC, the leak investigation experts in California at 805-801-2380.  Let’s discuss your situation and see how we can help you!

Private Client Hires William Leys Waterproofing Consultants LLC to Observe, Document and Report on HOA Experts Water Intrusion Investigation Related to Dispute on The Cause of the Intrusion

Water Intrusion Can Cause Considerable Hidden Damages if Left To its Own Devices

It started with a leak into the condominium owners unit, and after 4 months, the cause of the leak still remains unknown. With their home upended by drywall being removed, dehumidifiers running constantly, and continued water intrusion occurring, the home owner has hired William Leys Waterproofing Consultants LLC to represent them as their advocate and expert in determining where why and how water Intrusion continues to occur.

We will be attending and documenting the investigation by the HOAs experts and examine their findings after another in-depth intrusive moisture inspection. With potential legal liability on the line, the owner needs expertise working for their best interest. Our history of performing water intrusion investigations and expertise in documenting provides our client with comfort and security in having us on their side.

With some HOAs it’s up to the owner to prove that the HOA is negligent in protecting the building, and unfortunately this HOA is proving to be difficult to work with and get them to accept responsibility. Our task is to provide the expertise and the proof that the responsibility lies with the HOA, or show the client why it’s not the HOAs responsibility.

When your HOA is not doing its job and remediating water intrusion and you believe it’s their responsibility, by hiring the experts at William Leys Waterproofing Consultants LLC may help sway their opinions to be favorable to your claims.

Large Medical Facility Tenant Improvement Contractor Retains William Leys Waterproofing Consultants to Perform Quality Assurance Inspections in Santa Maria

We’re pleased to announce that we’ve been retained to perform quality assurance inspections for a medical facility that will be waterproofed with crystalline waterproofing on a building that has suffered from water intrusion.

The facility is an ob/gyn office that needs to be kept sterile and moisture and mold free. Angelus Waterproofing of Huntington Beach will be applying Koster Systems crystalline waterproofing to the interior of the block walls as the exterior has a stucco system that would be costly to remove. With our assistance the owners of the building selected crystalline waterproofing as the best choice given the conditions and restrictions.

With our years of experience conducting quality assurance inspections and having a highly qualified waterproofing contractor perform the work, the building will be protected from water intrusion for many years as crystalline waterproofing is a permanent system that is impervious to degradation unlike many typical liquid or membrane applied systems.

If you are in need of ensuring your building is being waterproofed properly, please contact us to discuss our quality assurance inspections and how they benefit you, ensure that the waterproofing is being installed correctly and meets all requirements for the manufacturers warranty.

Buildings Don’t Come With “Maintenance Required” Warning Signs That Automatically Pop Up

I started up our company vehicle the other day, and on the dash popped up this warning “Maintenance Required”. We have a Toyota Tacoma, a vehicle that’s legendary for going 300,000+ miles or more. However the taco still needs maintenance, repairs and replacement of parts to get to 300,000 miles. Oil changes, flush the transmission, rotate the tires, a new battery. Take care of your Toyota™ and it will take care of you for years and years.

Why don’t buildings have this?

So I checked and sure enough it’s time for the next oil change. So easy, I don’t have to think about when it is time to change the oil, the vehicle tells me it’s time. And I wondered, why can’t buildings have this built into them? Unfortunately no one has figured out a way to have maintenance required warning signs pop up on a building, at least not yet.

However it’s important to remember that buildings do need required maintenance. Maintenance like roof inspections, cleaning out gutters, repainting, cleaning and repainting the decks,… Stuff like that plus more.

That’s why we here at William Leys Waterproofing Consultants LLC are here; to tell you that your building needs maintenance. We offer various services such as roof inspections, deck inspections and building inspections. We do inspections so that you can schedule maintenance when it’s required.

Don’t let your valuable asset deteriorate, keep up on maintenance and inspections and your building will last and last. Call us today at 805-801-2380 for a free conversation about your buildings inspection needs and how we can help your building be the Toyota™ of the construction industry!

“Structural Issues” Cause Bay Area Condo Building to Be Evacuated Until Temporary Shoring is Installed

UPDATE AS OF 3/19/26

We spoke with reporter Kevin Nguyen at the SF Standard regarding this property after he reached out to us asking about this property. We were the source that alerted Kevin to the fact that the picture below by  Anna Nevskaya showed failed post tension cables poking out from the building.

Turns out that post tension cables that support the podium deck slab have failed. I saw a review on Google by an owner at the property and knew instantly this building is F’d.

I’ll now predict that the slab can’t be fixed and the building will have to be demolished. What engineer in their right mind would believe that the other cables that aren’t broken are ok and just recommend repairs to the failed cables? No one in their right mind would in my opinion.

Post tension cables have broken in numerous places in one area as seen in this photo taken by Anna Nevskaya (and republished here for public knowledge.) The cause is unknown but is likely related to either damage caused by a massive fire that occurred during the construction, water damage or both.
