Does Your HOAs Reserve Study Include All the Costs/Work Involved to Replace a Balcony at the End of Its Useable Life?

I’ve spoken with numerous reserve study folks about balconies/decks/walkways and the scope of work that replacing a balcony requires.

You can read our article about installing deck waterproofing systems at our articles page here

I’m not sure all of them understand that a waterproof deck replacement project is far more than just replacing the waterproofing system. Known as pedestrian traffic coatings, walking deck systems are composed of several different things, including flashings at the deck to wall and at any outside edges. Deck drains or scuppers may be involved. Door pans for the sliding or French door are also something that needs to be addressed.

In order for our readers to better understand, I’m going to break down the work a deck replacement involves.

So let’s say your exclusive use common area balconies are 25-30 years old, have been reasonably maintained but are now starting to require a lot of repairs. Your reserve study says the decks need to be replaced at year 25-30. Like any building component, deck waterproofing systems do wear out and need to be replaced.

A typical detail that must be followed when installing new flashings and waterproofing.

Let’s break down what a full deck replacement really looks like and my reserve study peeps can go back and see if their projected costs include the following basic scope of work. If you’re a Board member or HOA manager, you’ll want to ask your reserve study provider if they are taking all the work necessary into account for estimated costs of replacement.

So to start with, the deck waterproof coatings needs to be removed. This will also include removing and installing new plywood substrate. Always replace the existing substrate with plywood as it required by every  traffic coating manufacturer. The  contractor will need to  open the walls in order to remove the deck to wall flashings as well as removing the sliding door to access the rough opening and the door flashing/door pan under the sliding door. Breaking open stucco or removing other wall finishes to remove and reinstall flashings requires restoration of the wall after the deck is replaced. Replacing a three coat stucco wall is one thing, but replacing other wall finishes such as EIFS or Hardi Board will incur further expenses.  Older siding such as Masonite, an inexpensive siding that’s no longer manufactured, may require even more work to replace it with new current siding systems.

There’s an art to installing pedestrian traffic coatings.

After stripping down the deck to the joists, some joists may be damaged and bed reports or replacement. Those unknown costs should have a line item in the reserve study under a unknown costs category. Maybe ask the hosts will be ok, maybe they won’t. It’s better to budget for some repairs.

The sliding door or French door needs to be removed to install a door pan. (Doors are usually an owner responsibility to maintain, repair and eventually replace.).  This is a good time for old doors to be replaced with modern doors that have glass that reduces UV and heat coming through and are generally better at functioning and resisting rain and wind. Rarely will a contractor remove doors without first informing the HOA that doors may be damaged and that they aren’t responsible for any damages to the doors. If the doors are 25+ years old, owners should buy new doors.

Typical balcony flashing system detail.

The deck, if it doesn’t already, needs to be sloped to drain, either to an open edge or to a deck drain or scuppers.

New flashings at the deck to wall need to be replaced with new flashings, integrated into the door pan. If there are scuppers on the outside wall, they need to be integrated with the deck to wall flashings.

Always replace deck drains that go through the floor of the deck during the deck replacement. Modern deck drains are using brass plumbing pipe and stainless steel flanges welded to the pipe.

A high quality deck waterproofing system is recommended. Cheap deck waterproofing systems have a shorter useable life span and generally require a lot more maintenance.

One issue that may arise during a deck replacement project is that you’ll probably need a building permit. New codes may take precedence. Right now code generally requires railings to be 42″ high and have openings  4″ apart or less. If your current railings don’t meet that standard, that’s a cost that doesn’t show up in a reserve study. So you need to have a contingency for increased costs necessary to meet building codes of the future.

Once your new deck system is installed and the walls are closed up and you turn the decks back to the resident, you now start the clock ticking on the maintenance cycle that the EEEs require. Many pedestrian traffic coating systems require resealing/painting the decks every 3-5 years. If you fail to do so and there’s a problem down the road, a warranty claim may be denied. Besides keeping the deck looking nice, a clean and reseal gives the association the ability to inspect thru deck and make any minor repairs before they become big repairs.

So your reserve study needs to have a line in it for deck maintenance. Your deck contractor can give you a schedule for resealing. Trust me when I say I recommend you follow the maintenance schedule. If you do you’ll maximize the expected life span of the waterproofing. Because of the costs to replace a deck earlier than it’s expected life span, you want to do this.

Your reserve study also needs a line item in it for reserving for the replacement costs of the deck again 25-30 years down the road.

Follow our advice and your association  may realize lower costs in the future. If you fail to inspect ,maintain and repair,you can expect a shorter usable life span, and large costs to replace the deck before its time.

Does your association need help in determining costs, inspecting your decks for maintenance requirements or to get a grasp on what condition your EEEs are in to dial in your decks estimated life spans for your reserve study, reach out today. We can help your HOA take control of your EEEs rather than letting your EEEs control you.

William Leys Waterproofing Consultants LLC Becomes a Member of the North American Building Compliance Testing Association (NABCTA) !

We’re the Central Coast’s Solution for Building Envelope Compliance Testing!

William Leys Waterproofing Consultants LLC is proud to announce that we have become members of the North American Building Compliance Testing Association (NABCTA) !

We’re constantly seeking to improve our skills, increase our knowledge and bring the Central Coast of California local expertise and professionalism.

If you need building envelope leak testing, litigation support on waterproofing defect claims or building envelope consulting, please reach out today! We provide ASTM E 1105 testing and full compliance reporting.

After a cyclic test, this recently repaired stucco wall was found to be leaking.
Another wall, another test proves that the stucco wall was improperly reassembled resulting in water intrusion into the building.
A spray rack is set up to test the walls and windows on a recently built medical building in Templeton CA

What is E 1105 you ask?

How the Testing Works

Water Spray: A calibrated outdoor spray rack applies water uniformly at a rate of 5.0 gallons per hour per square foot.Air Pressure: An interior or exterior chamber creates a controlled air-pressure difference to simulate wind pushing rain against the building.Observation: Inspectors watch the interior side of the test specimen to see if any water penetrates past the building envelope.

Testing Procedures

Procedure A (Uniform Static Pressure): Applies a steady, constant air pressure difference, usually for a 15-minute test period.

Procedure B (Cyclic Static Pressure): Cycles the air pressure on and off (e.g., 5 minutes on, 1 minute off) for multiple cycles to mimic gusting wind.

Why It Is Used

Quality Assurance: Verifies that field installation, flashing, and sealants were done correctly right after construction.

Forensic Investigation: Helps locate the source of active water leaks in existing buildings.

Quality assurance inspections can also help ensure that the building envelope is being installed correctly. We offer QA inspections for building owners during construction. Catch problems before the building is closed in.

If you are building new construction, get your windows and doors tested before closing in the building. Call today 805-801-2380

Balcony Collapse in Hawaii Injures Seven People!

We’re still trying to get more information, a balcony collapsed in Hawaii with 7 people on it. The balcony appears to have only been nailed to the building from what we can see.

As seen here, the deck appears to have fallen off the building. It appears to have been nailed into the building instead of bolted. An inspection probably would have caught that flaw.
Photo used under the fair use doctrine for education.

This is why inspections matter! The 11th anniversary of Berkeley was two days ago, and here we are again, another collapse. For the people on this balcony, they were injured but they will all be going home from reports I’ve read.

Please schedule your inspection ASAP, if you are renting property either through Airbnb or long-term, protect yourself and your tenants with an inspection.

We serve San Luis Obispo County as well as Santa Barbara and Ventura County for deck inspections under SB326 and general inspections for rental and personal property.

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.

Instagram Featured Video Stair Rebuild by One Structural/Balcony 1 Shows Multiple Construction Defects Being Installed in Real Time!

“Clowns to the left of me, jokers to the right, here I am, stuck in the middle…”

A recent Insta video posted by One Structural/Balcony 1 reminded me of the lyrics from a 1972 song by Stealers Wheel… And after watching the video several times I wondered why I wasn’t having a stroke over the numerous defects in their work. The video purports to show their expertise in rebuilding a set of stairs and waterproofing them. (The video appears to have been removed from their profile located here https://www.instagram.com/onestructural?igsh=MzRlODBiNWFlZA==)

In the video it showed a timeline of rebuilding a set of stairs. As I watched it play out I screenshot a few pics, see below.

Starting with the framing rebuild, we can see water/fungus damaged stair stringers that weren’t replaced, damaged sheathing on the wall that wasn’t replaced and new wood that looks like my 3 year old nephew installed.

A Recent Home Inspection Shows Why a Seller Provided Home Inspection Report is Essentially Worthless

The other home inspector missed this “little” issue

A recent inspection we performed for a prospective buyer of a condominium in San Luis Obispo demonstrates perfectly, why you as a buyer need to have your own inspections done at your own cost. This particular inspection found many issues that were glossed over as simply needing patching and painting rather than complete replacement of major components such as windows, doors, decks and subflooring under a shower.

The seller had a pre sale inspection done at their expense and provided that report to the prospective buyer. He had questions and doubts about the report and reached out to us after searching for a waterproofing and building consultant.

Our inspection found that many items the other inspector glossed over in his report as needing “patching and painting” or minor repairs were far from the real situation which was that all the doors and windows were past their useable lifespan and needed to be completely replaced. We found dry-rotted framing on decks, open and exposed framing on columns, dry-rot in the substrate below a shower floor which requires the substrate to be replaced due to fungus infestations.

William Leys Waterproofing Consultants LLC Helps Clients Whose Property Has Been Damaged Caused By Construction Defects Recover Financially

Even before William Leys Waterproofing Consultants LLC was formed, President Bill Leys has been assisting clients throughout California recover financial damages from contractors who caused construction defects that led to water intrusion and property damage. As an expert waterproofing consultant serving San Luis Obispo, Santa Barbara, Ventura, Kern and Los Angeles counties, we’ve helped clients recoup hundreds of thousands of dollars in the past few years.

Our expertise in building technology and waterproofing methods, investigative skills and ability to document and report on the problems, the causes and suggested repairs needed have allowed our clients to convince the Contractors State License Board, the contractors at fault and their Bond companies to act. We’ve seen great success with the CSLB investigating complaints, contractors agreeing to repair defective work and have bond and insurance carriers pay on claims made by our clients.

Some recent success stories include helping a client in San Bernardino recover 5k+ in damages caused by faulty deck waterproofing work by a contractor from Palm Springs. Our investigation found that the contractors “expert witness” actually had business ventures with his client, leading to the Judge concluding the contractors witness had implicit bias in favor of his client. In other words, his testimony was rejected by the Court. Our client got a court order that the contractor had to remove a lien on their home and could not collect $5,000 they claimed our client owed.

No blocking between the old and new plywood is a defect that will cause any waterproofing to eventually fail.

Another success story found us assisting a client in Avila Beach whose recent kitchen addition was apparently leaking. Our investigation found windows were leaking from faulty installation, deck flashing that leaked from faulty installation and as a result of our testing and report, the client was able to successfully initiate a claim against the contractors general liability insurance and recover funds to repair their damages. The client made a confidential settlement with the insurance company for well over 6 figures.
