ASTM Standardized Water Testing Proves That Construction Defects Exist at a Condo in Los Angeles
William Leys Waterproofing Consultants LLC was recently retained by an upscale condominium complex in Los Angeles to investigate leaks from one recently repaired deck and stucco wall on one condo unit that was claimed to be leaking into an adjacent unit, causing damages to the home.
Using ASTM approved water testing methods, we set up a spray rack that sprays up to 2 hours of rain in a twenty minute period to mimic actual weather conditions.

Using our methodical testing approach, we were able to prove that the wall shown in the photograph above was in fact leaking. Using litmus paper and visual observations during the methodical cyclic testing as prescribed by ASTM showed conclusively that the newly repaired wall was in fact leaking at four locations.

With this proof in hand, the Association can now move ahead with correcting the deficiency and fix the interior space. Liability on the proper responsible party that created this defect can now be established and legal counsel can now move forward with making claims against the contractor and his insurance company. Without standardized ASTM testing their claim would be very difficult to support in a court room.

When your buildings leak, call us first to establish where the leaks are coming from and with our investigative team of water intrusion experts, we can help you determine the source of the leaks, why they leak and who is responsible for the leaks. Don’t wait or let your contractor deny responsibility, put us on your team!

You Gotta Read the Fine Print! HOA’s Need to be Careful of Companies Advertising “Free” or “20% Off” Type Offers on Balcony Inspections

William Leys Waterproofing Consultants LLC was recently contacted by a member of an HOA in Ventura County where that member had learned that his association’s Board of Directors were considering passing a special assessment in the range of 2 million dollars for repairs to balconies and stairs.
Information we got from the owner was that a large nationwide HOA reconstruction firm told the HOA that they had 13 emergency repairs and 300+ non emergency repairs to do and the budget was apx 2 million dollars for this work.
The resident also learned that this nationwide HOA reconstruction firm had waived the $41,000+/- Stage 1 inspection fee provided they were given the repair work. We believe that to be highly unethical and so does that owner. We provided a letter of opinion that the association could self finance the non emergency repairs over a period of several years, taking on a couple buildings at a time to make repairs.
We’re also seeing companies now advertising “free inspections” and “20% off” specials. With all of these offers, there is always fine print, and fine print never benefits the consumer. If you’re going to buy into these offers, make sure your legal counsel is protecting your interests by reviewing their contract before you sign.
One thing these companies have in common is that they are larger firms with a lot of overhead and with the slowdown of inspection requests coming in they need to churn business. Due to the other services that we offer, we are staying busy with work that they don’t offer such as construction monitoring and building envelope inspections.
At William Leys Waterproofing Consultants LLC, we provide upfront honest bids on SB326 inspections. We strictly follow SB 326 requirements by guaranteeing that an engineer is physically present at the inspection and inspecting the structural elements. We have competitive prices that are straightforward without fine print in our contract. We have a waterproofing expert who writes the waterproofing report which is then appended to the engineers sealed and signed report.
Our strict ethical standards demand that we only inspect and report for the benefit of our clients, not ourselves. We believe that inspectors should not be bidding on repairs.

How A Building Envelope Consultant Can Add Value to Your Residential Building Project

As building envelope consultants we are often hired to determine where why and how a roof, siding or windows are leaking. After doing destructive testing and finding what caused the problem, it’s often an installer error that created the problem. Yes sometimes it’s defective waterproofing products, but that’s the exception, not the rule.
For architects and their home building clients, one way to ensure that the building envelope is going to perform correctly for it’s expected life span is to hire a waterproofing consultant to review the architects building envelope details, and to perform quality assurance inspections while the building is being dried in. Drying in a building entails roofs, below grade waterproofing, building paper over the plywood covered walls, window and door flashing for example. All of these need to be installed in a sequence to work together for the building to remain leak free.
Whether you are building tract homes, commercial/residential, condos or a spec home, a small add to the project budget to include a waterproofing consultant to assist in keeping your project leak free is a good investment. Consider the costs when a building does leak; there’s investigative costs, loss of use, possible mold claims, expensive repairs and everyone is aggravated.
William Leys Waterproofing Consultants LLC is here to help you with making your building project a success. Reach out today for a discussion on how we can help bring value to your project.
A Roofing Contractor Messes Up, William Leys Waterproofing Consultants LLC Helps Client Get It Fixed
A Low Slope Roof Installation Went Awry When The Contractor Deviated From The Manufacturers Installation Instructions
William Leys Waterproofing Consultants LLC Steps in to Assist The Building Owner Get the Work Corrected
A recent consult job that we had for a client who just had a new low slope roof installed on their building showed the reason that building owners should consider hiring a quality assurance inspector to ensure that the roof is installed right the first time and doesn’t have to be done over.
A client reached out to us who just had a new roof installed on their building. They had concerns about the workmanship and requested our assistance to inspect the job and document the problems with the installation. A low slope roof with a single ply TPO membrane had multiple issues with the installation.







As you can see from the photo gallery we found numerous problems with the installation. We wrote a detailed report for the client who then was able to go to the contractor and ask them to make corrections to their work. The city building department refused to sign off on the permit for the roof because of the poor workmanship and the client threatened to complain to the Contractors State License Board if the contractor did not step up and replace and repair his poor work.
All in all a happy ending for the client who had paid quite a bit of money for this roof. We would encourage anybody who is replacing a roof that’s going to cost over six figures to add a little bit more money into their budget and pay for quality assurance observations during the installation which had this client done so would have avoided this issue.
