Moisture Stains on My Ceiling or Dark Stains around the HVAC Vents Covers

A lot of homes we inspect in Florida have condensation on the HVAC duct vent covers and moisture stains or mold on the ceiling around the vent.  The cold air from the vent coming in contact with warm air at the ceiling or uninsulated duct boots in the attic causes condensation to form on the vent covers.  Frequently, this condensation causes moisture stains on the ceiling.  The moisture stains can be an ongoing challenge if the cause of the condensation is not addressed. 

The water marks on the ceiling and the droplets of moisture on the vent cover are likely caused by insufficient insulation on the ducts in the attic, inadequate insulation or uninsulated vent boots, or leaking of hot / warm attic air around the vent boots. 

What is a vent boot?   

The vent boot is the box in the attic that the air conditioning duct connects to on one side and the vent cover on the ceiling is screwed into.  Newer boots are often constructed out of insulation board or duct board.  The older types of boots were constructed out of metal.

The above picture shows an uninsulated vent boot attached to the HVAC duct.  The vent cover connects to the vent boot on the inside of the ceiling.  This boot has no insulation and the joints are not sealed well.  The sealant between the boot and the ductwork is leaking and there is no sealant between the duct and the ceiling.  Moisture accumulating on the vent boot drips down until it is absorbed by the drywall ceiling board causing moisture stains around the vent cover.

People often mistake the dark stains that sometime form around the vent for mold.  The plausible cause of the dark stains is the vent boot was not sealed to the ceiling board.  The dust from the attic, then sticks to and stains the moist drywall board around the vent cover.

When you see the stains around your ceiling vent covers don’t ignore them.  Water damage is costly to repair and moist conditions may encourage mold growth.

Random Moisture Stains on your Ceiling

If you have random stains on the ceiling; it may be the joints are not sufficiently insulated or sealed.  Moisture stains are visible at the joints of the ductwork in the attic in the picture above.  Condensation forms on the joint and may not evaporate in the attic.  If the condensation continues to drip, it may saturate the insulation and cause moisture stains on your ceiling.

Recommendation:   We recommend sealing the joints to prevent cooling loss in the attic and random stains on the ceiling.  Sealing the joints will also improve the efficiency of your HVAC system and help reduce your cooling costs.

 

Main Causes of Condensation at AC Vents

Not enough insulation on the ducts themselves

Cold air traveling through your ductwork in a warm or hot attic forms condensation if the duct is uninsulated or under insulated. The air ducts in the attic should be well insulated.  You should have your air conditioning system and ducts inspected if it struggles to maintain a comfortable inside temperature on hot days or you notice condensation on the ceiling or vent cover.

The insulation on the duct above was separated from the duct.  Condensation had formed in the duct vapor barrier and over time had stained the middle of the ceiling.

Recommendation: Ducts in the attic should be well insulated and in good repair.  Damaged or old under insulated ducts should be replaced.  Consider replacing the ductwork in the attic if it is 20yrs or older.  It will be a good investment that will be easily recouped and will save you money on your future electric bills.

Uninsulated vent ‘boot’

The metal box in your attic that attaches to the duct and the vent cover screws to is the boot.  In an attic in Florida, the uninsulated boot will generate large amounts of condensation due to the cold air in the boot and the hot air in the attic.

Above is an uninsulated galvanized duct boot. This boot was cold in the hot attic and caused water to condense on it and drip onto the ceiling.

Recommendation:  We recommend having an HVAC contractor evaluate the condition of the ductwork.  Sealing the duct to vent boot joint and insulating old metal ducts will help reduce condensation around the vents.  Older deteriorated ductwork should be replaced.

Dark Stains around your vent Cover

Dark stains around your vent covers may be mold, but more likely it is dust collecting on the damp ceiling.  If the boot is not properly sealed to the ceiling, it will allow attic dust or dirt to seep out of the crack between the ceiling and the vent cover.  Also you may discover a leak where the vent boot attaches to the duct. If not properly sealed, the cold air leaks out, meets up with the warm attic air and creates condensation.

Recommendation:  Find and seal the leak. If the problem vent is easy to access from your attic, you may be able to check for and fix the problem yourself. We recommend consulting with a local HVAC contractor to evaluate and repair the HVAC ducts. 

Covering Stains around the Vent Cover

The dark or water stains around your vent cover are difficult to cover.  When the repairs have been made, the ducts have been caulked and no more condensation is present on the covers it will be time to cover the stains. 

Normal ceiling paint will not cover up these stains.  Moisture and dirt stains around the vent cover are stubborn stains.   Even with multiple coats of ceiling paint, the stains continue to bleed through the ceiling paint.

Recommendations:  We recommend you first cover the stains with two coats of KILZ 2 Multi Surface Primer & Stainblocker then paint with your choice of ceiling paint.

Deltona Home and Building Consturction is Booming

Orlando new home construction was up 51 percent in 2018 compared with the year before.  Construction was led by a surge in apartments but also increases in single family homes, townhouses and condos. Home builders started 16,238 single family homes last year, 12 percent more than 2017. Developers started 12,629 apartments, the most since the Census Bureau began tracking the statistic in 2004. West Volusia county is seeing a huge building boom in Deltona and DeLand.

Deltona building lots are disappearing quickly.  More than 2000 building permits in Deltona were issued in 2018.  Newmark, Normandy, and Elkam used to have available building lots but those are either filled with new homes or have homes under construction.  New home developments are being built in and around Deltona, and the landscape is quickly changing.  Howland Blvd. has a new Halifax Hospital, Avent Health Emergency Room, Burger King, WaWa, O'Reilly Auto Parts, Dollar General Store, Dunkin Donuts, and an Honest-1 Auto Care. 

Central Florida home construction is now at the highest level since 2009 when Obama took office. Home sales peaked in 2005 during the middle of the G.W. Bush administration and hit the bottom early in Obama's first term. Sales have since recovered, but are still at levels not seen since the early 1990s when G.H.W. Bush was leaving office.

Building material, skilled labor and lot shortages held new home construction down. Most of the skilled labor were retrained when unemployment peaked in in other fields and did not return when the economy improved.  Builders use of unskilled labor has them spending more time on repairs after the new homes are sold.

Our home inspection schedule has been full in part due to the number of re-inspections required on new home sales. Nationwide there is a labor shortage of 300,000 skilled workers like roofers and framers.

Concentrated urban areas of Orlando are adding homes at the fastest rate. Demand continues to be high in areas such as St. Cloud, Lake Nona, Western Orange County, Western Volusia and Lake County.

Painting Tips from Your Deltona Home Inspector

Paint keeps your wood siding from rotting and the stucco from cracking. Florida weather takes a toll on our homes. As a home inspector, we see the results of DIY projects and even professional projects gone wrong every day.

Stucco

Fill cracks before painting!

When you purchase a new stucco clad home in Florida, it will usually have an acrylic paint. Builders choose acrylic paint because it has a higher permeability value not just its lower cost. After five years, this paint oxidizes or becomes caulky and will rub off on your hand.

Fill cracks before painting.

Permeability means the stucco can breathe better, which is what stucco is supposed to do. This allows the stucco siding to cure slowly for the first five years after construction. During this time you will typically see cracks appearing from the home settling. Do not use an Elastomeric paint within the first five years, as it will seal the stucco and may cause more cracks. After five years you want to fill any cracks that have developed and seal the stucco siding to keep the moisture out.

An acrylic paint will not last as long as an Elastomeric product, so it will have to be repainted more often but is less expensive. Elastomeric paint seals the siding and will stretch; this allows small cracks to be covered. Once you use an Elastomeric paint you should only use an Elastomeric over the top of it. Acrylic paint does not stretch and will crack as the Elastomeric paint moves with the expansion and contraction of the home.

Vinyl

Vinyl siding comes in a variety of colors and extra care needs to be exercised when choosing to paint vinyl siding. The formula for white or light colors of vinyl is different from that used for colored vinyl siding. 

The reason is a light color reflects more heat and UV rays, while a darker color absorbs them. White or light color vinyl siding should never be painted a dark or flat color. Painting this vinyl will cause it to absorb heat which makes the siding warp. 

Nothing looks worse on a home than warped vinyl siding. Lighter and glossy paint reflect more heat and UV rays. Darker and flat paint colors absorb heat and UV rays. 

Wood

It is import to make sure extra care is used when preparing wood siding for paint. Clean and replace all damaged wood before painting. Make sure your wood is dry enough to paint or you will seal in the moisture. Remove old dried caulk from joints. Caulk all joints that are open. All wood decays and rots, but moisture accelerates the process.

Do you need a primer?? Yes, primer not only helps the paint stick better and make the color more consistent but it also absorbs into the wood. Do not use expensive paint over dried out or new wood, it is very porous and will absorb more of the expensive paint. Priming is necessary to stop wood-bleeding or if you are covering gloss, grease, or other areas that make paint-adhesion difficult. Primer is cheaper than paint and should be used to prepare the wood for paint. 

Is Paint and Primer in one a scam?? It is great for just changing color, but is a more expensive product than paint and goes on thicker with 1/2 the coverage area and should be avoided on wood that will absorb a lot of paint.

Give yourself plenty of time to complete the project or hire a professional. Do not leave unprotected wood exposed to the weather and make sure all paint is dry before it rains.

These are just a few of many suggestions. If you are in doubt, please hire or consult a professional. Choosing the wrong paint can lead to extensive damage. Painting the exterior of a home is a huge and important project. The time to decide if it is too much work for your skill level is before you invest in paint, brushes, rollers, pans, tape, tarps, and tools.

Deltona Home Inspection and The Florida Building Code

The Florida Building Code

The Florida Building Code became effective on March 1, 2002 and was created by the law ratified by Florida Legislature in 1998. The Florida Building Commission was motivated to create the first state-wide building code after Hurricane Andrew devastated South Florida on August 24, 1992.

Just because we have a statewide building code now, people assume we have always had a building code in Florida. New home buyers always ask me, if the house they are buying is built to code. As a home inspector we do not quote code but the code in Florida is new. If you are buying a home built before 2002 the question, "Is the home built to code?" is not relevant.

South Florida Building Code

South Florida Building Code has been around much longer. The reason for creating the South Florida Building Code was tropical and hurricane storm damage. Between 1900 and 1950, 108 Hurricanes affected the State of Florida resulting in 3,500 deaths and property damage that would be equal to 4.5 billion dollars in today's currency.

In South Florida, a panel was formed and they worked with the American Society of Civil Engineers (ASCE) and other research groups to devise wind-loading design. They created a formula for calculating anticipated wind loads from hurricane force winds, taking into account both the wind speed and the height above ground. Miami-Dade County commissioners voted October 29, 1957 and the South Florida Building Code became effective in Miami-Dade County, December 31, 1957. Broward County later adopted a modified version of the South Florida Building Code, Dade County Edition.

Florida Building Code Background

When Hurricane Andrew hit South Florida, it exhibited a serious statewide deficiency in home construction standards. Our antiquated system of locally administered building codes and enforcement was inadequate. A statewide building code and enforcement agency was needed. Compliance or enforcement in a single county could affect homeowner insurance companies statewide.

Andrew broke all previous records for insurance losses at the time, and was the direct source of Florida's worst insurance catastrophe. Florida was seriously under-insured and overexposed; insurers suddenly comprehended that all of the worst case calculations were completely underestimated.

Many insurers just left Florida and the ones that stayed raised rates to staggering new levels in order to avoid the very real risk of sudden bankruptcy following another huge storm. Homeowners all over Florida were affected as they saw their rates rise drastically and found a lack of available new insurance threatening to pull the plug on development in every part of the state.

We were using the 5th Edition of the Florida Building Code from 2014. The Effective Date for the Florida Building Code 6th Edition (2017) is December 31, 2017.
