Stucco Inspections in Houston

What is Stucco?

The term “stucco” is used to describe a type of exterior plaster applied as a two- or three-part coating directly onto masonry, or applied over wood or metal lath to a log or wood frame structure. Stucco is applied wet and hardens to a very dense solid. Stucco is valued as a siding material for its attractiveness and durability and is a relatively low-maintenance (not maintenance free) exterior finish.

Our Proven Stucco Testing Process

Bryan & Bryan Inspections takes a phased approach to testing for moisture intrusion issues with stucco. Our stucco inspections consist of Phase 1 and Phase 2 testing, which is completed within one onsite appointment, and the deliverable is a custom report detailing our findings.

Phase 1

We begin with Phase 1, which is a preliminary visual evaluation of the home’s exterior. We encourage this to be done with the client present. At this time we are looking for visual cues about how the system is performing and how it was installed. We’ll walk the property and take note of visual evidence of cracking, staining, and key installation details, and also look for the absence or inclusion of certain elements – head flashing above windows and kickout flashing at roof-wall intersections, for example. At this time the client is encouraged to discuss areas of concern, areas where moisture intrusion has already occurred (e.g. water staining around interior windows or doors), or where there has already been remediation work, caulking, etc. as the result of moisture intrusion issues or general maintenance.

Phase 2

Because it’s impossible to see through walls in order to obtain facts about how the home is performing, it is necessary to move into Phase 2 testing. Phase 2 testing is an invasive testing procedure known as moisture probe testing. This requires us to drill two small holes, about one inch apart and roughly the diameter of a pencil. Through these holes we insert a moisture meter to test the moisture content of the substrate behind the stucco, or the wooden part of the home. We’re most concerned with testing portions of the home that are above the foundation and/or on a wooden substrate. We typically need to test and map out the most exposed areas on each wall section, such as the lower penetrations/first floor windows, as well as the roof-wall intersections and any other areas of the construction that are vulnerable based on how the home was originally designed and built.

All of the moisture readings that are taken are recorded on full elevation photos of the home in our proprietary software in the location that they were taken from, providing a “map” of the moisture found in the home at the time of the inspection. We will then help you to understand the relationship between all of the readings. Other useful information is also gathered, such as whether the substrate is soft, if any decay is present, or if the area tested dry and firm. All of the holes are then filled with a professional sealant.

If we are able to gain access to the interior of the building to evaluate areas that have evidence of moisture intrusion (e.g. leaky windows, water staining) and check the attic, it does allow us to be more thorough in our inspection. This access often allows our team to learn more about how the system is performing and also note any signs of moisture intrusion.


Custom Reports

All of the information we gather during stucco inspection is compiled into a custom report available by 9am the following day. The report includes elevation photos with moisture readings, detailed photos with specific deficiencies, a summary checklist, condition assessments, and recommendations for next steps.

Our goal is to educate each client through the inspection process which is why we encourage clients to be present so that we can personally answer any questions and address any concerns that they may have. Do not hesitate to contact us if you should have any pre or post inspection questions.

Frequently Asked Questions

Although stucco systems have been in use for many decades, in recent years it has become popular to place these systems over wood sheathing and studs. These systems can be well designed, but unfortunately they rely upon installation details that are completely concealed after the system is completed. The most important part of the stucco cladding system is the moisture barrier and flashing system. We are finding many homes built in the last couple decades that have severe water damage are due to poor detailing by the original installers. Many of these issues go unforeseen by the home owner because they are concealed within the wall cavity. It’s not until professional testing is performed that these hidden issues are discovered. Some issues, if caught early enough, do not require removal of the stucco, however, often times large wall surfaces need to be opened or completely removed to make the correct repairs. The most drastic cases are entire home tear offs.

Most times, you can’t. It is only with a comprehensive professional moisture intrusion inspection that we can identify the issues behind the stucco. There are many different methods and tools that can be used to identify potential trouble spots. Regardless of how suspect areas are identified, you cannot know exactly how much moisture is trapped without penetrating the stucco and directly measuring the moisture content of the building materials inside. An intrusive probe is required for the determination of specific moisture content. The level of moisture content of the homes substrate, including recent weather conditions, leads us to how we need to address the issues.

Very Important: A scanner or infrared camera are great tools to help us locate moisture but cannot be used alone. The wet areas must be probed for rot and ACTUAL MOISTURE CONTENT, and then mapped to meet the test protocol. It should also be noted that a thermal imaging camera will not detect damaged areas that are not wet, while invasive probing does allow you to feel the firmness of the structure, or the absence of the structure in cases of extreme rot and decay. Short of removing the entire system, probing is the best method of testing stucco systems.

All Bryan & Bryan Inspections home inspectors are trained to perform full home thermal imaging services. Thermal imaging is a great tool that can help us identify where potential problem areas may be within a stucco home, however, infrared cameras are very sensitive to weather conditions and should only be used by those that truly understand the technology and conditions that affect them. If not used properly, they often times produce false images that miss problem areas or indicate problems that may not be present due to external factors. Infrared cameras can be a very useful scanning tool, but again, you only know for sure how much water and damage may be behind the system by inserting probes and measuring the moisture content.

As a certified and very knowledgeable inspection company, we may use thermal imaging on inspections, when weather and other conditions support its use, to detect anomalies in a system and to help locate potential problem areas. We then verify our findings by testing those areas using resistance type probe meters to measure the associated moisture.

The moisture meter uses two narrow probes that require holes that are about a 1/4 inch in size. This is roughly the diameter of a standard pencil. After testing, all of the holes are subject to our proprietary cleaning process and are filled with a professional sealant that closely matches to the color of your stucco. Because of the texture of the material, the patches are generally not visible. Please remember it may be impossible to match the colors exactly due to weatherization and solar fading of the cladding or stucco. The inspector takes every precaution to make sure that the test holes are sealed to maintain the integrity of the exterior stucco and to preserve the appearance of the home.

Not necessarily. It depends very much on how wet they are, how long they have been wet, and how much area is affected, as well as what deficiencies are present within the system that caused the area to get wet. Corrections can range from simple caulking and sealing, to partial removal and repairs, to complete removal of the system and structural repair to the walls behind. The test probe moisture measurements, destructive testing and other factors will help you to make the final decision as to the full scope of repairs.

Stucco can be painted. Portland cement-based paints are very compatible with stucco because they are made of the same material. These paints should be scrubbed into the surface and fully cured. Alternatively, you could consider a colored stucco finish. These finish coats are often made with white cement and pigments, providing the widest range of colors. Premixed materials are color matched from batch to batch and are most consistent. Additionally, the fact that you are placing a finish coat with a nominal thickness of 1/8 of an inch instead of a paint layer usually gives more assurance of complete coverage. It is possible to paint with other types of paint, though these are usually not as long lasting as cement-based paint. Acrylic paints are long lasting and durable but change the permeability of the stucco (make it non-breathable) which in some climates may have adverse effects on the long-term performance of the system. We recommend contacting a painting professional for additional information.

Whether you have some type of atmospheric contamination, biological growth, or staining from another construction process, stucco can be cleaned effectively. Because it is important to choose an appropriate cleaning method based on what actually created the stain, there is no single best process for cleaning stucco surfaces.

To clean a dirt-contaminated surface, the following advice is useful: Like concrete and masonry, stucco is porous, and cleaning methods are similar. It is recommended to wet the substrate starting from the bottom and working towards the top. Pre-wetting the surface helps the wall shed water, preventing dirty water from being drawn into dry pores. It also begins to loosen soil so that it can be rinsed away. A garden hose may be effective. Special fan-type sprayers are available for increased cleaning power. Whenever using water on a cement-based material like stucco, the substrate should have set and hardened. Water under pressure can etch the surface and at higher pressures can even cut through hardened stucco. To prevent this, the water spray should be moved over the surface uniformly.

Most dirt is removed fairly easily. Cleaning power is increased by doing one or more of the following: Increasing water temperature, scrubbing with a brush, or using some type of chemical detergent. You should always test the method on an inconspicuous area to first demonstrate its effectiveness and to assure that it won’t damage the plaster. To clean stains other than simple soiled surfaces, we recommend contacting a pressure washing professional for additional information.

Prior to the start of any stucco or exterior cladding inspection, Bryan & Bryan Inspections requires a signed copy of our Building Envelope Inspection Agreement. In the case of a real estate transaction, we require signatures by BOTH the sellers and the buyers.

Stucco is an exterior wall finishing system that resembles stucco and has become increasingly popular for both residential and commercial structures. Stucco consists of a base layer of expanded polystyrene (EPS) insulation board attached to the wall sheathing. Additional EPS boards can be cut and rasped, shaped, formed and then placed or “planted on” over the base layer of insulation boards to give the façade the desired architectural features. Next, a thin base coat (typically 1/16” to 3/32”) is applied over the EPS boards, with a fiberglass reinforcing mesh fully embedded into the base coat. Finally, the finish coat, available in a wide variety of colors and textures, is applied over the base coat. It was developed in Europe over 40 years ago as an efficient way to insulate buildings from the exterior rather than from the interior. In Europe most exterior walls are solid masonry with no cavities for insulation. This is not the case in the United States where walls are hollow and can trap moisture and water.

Stucco components are not always installed properly and mistakes in applications are common. Failures often develop at roof rakes, chimneys, floor lines, and around windows, doors, and protrusions.

The resulting damage in most cases was from moisture getting in behind the siding and getting trapped behind the highly water resistant material with no way out. This caused framing to rot and foster mold growth between the exterior and interior walls. Damp and rotting wood is also a prime target for subterranean termites.

The potential for these conditions do exist with any type of exterior siding product such as brick veneer, wood, or vinyl siding. The problems with stucco, however, are exacerbated because of its superior water resistance. Once moisture gets in, regardless of its origin, it usually has no escape. The only means to determine if elevated moisture is present is for a certified stucco inspector to do an inspection with moisture analysis.
