San Antonio Texas Home Inspection Checklist Comparisons

Home Inspection Checklist Comparisons


All home inspections are different and can vary dramatically from state to state, as well as across regions, counties and cities. Most depend upon the home inspector and which association, if any, to which the inspector belongs. Because I am most familiar with home inspections conducted in accordance with the standards of practice established by the National Association of Certified Home Inspectors, the following information is based on NACHI guidelines.


Home Inspection Checklist of Items Not Inspected


In Texas, Home inspectors must be licensed by the Texas Real Estate Commission (TREC). Home inspector requirements.  Evan Bair is licensed by TREC. Evan Bair has years of professional experience in construction, maintenance and home repair. However, a home inspector's standard practice typically does not include the following, for which a specific license to inspect and identify is required:



General Home Inspection Checklist Items



  • Structural Elements.

    Construction of walls, ceilings, floors, roof and foundation.

  • Exterior Evaluation.

    Wall covering, landscaping, grading, elevation, drainage, driveways, fences, sidewalks, fascia, trim, doors, windows, lights and exterior receptacles.

  • Roof and Attic.

    Framing, ventilation, type of roof construction, flashing and gutters. It does not include a guarantee of roof condition or a roof certification.

  • Plumbing.

    Identification of pipe materials used for potable, drain, waste and vent pipes. Including the conditions of toilets, showers, sinks, faucets and traps. It does not include a sewer inspection.

  • Systems and Components.

    Water heaters, furnaces, air conditioning, duct work, chimney, fireplace and sprinklers.

  • Electrical.

    Main panel, circuit breakers, types of wiring, grounding, exhaust fans, receptacles, ceiling fans and light fixtures.

  • Appliances.

    Dishwasher, range and oven, built-in microwaves, garbage disposal washer and dryer hookups and smoke and CO2  detectors.

  • Garage.

    Slab, walls, ceiling, vents, entry, firewall, garage door, openers, lights, receptacles, exterior, windows and roof.


Home Inspection Checklist Items Needing Service

Home inspection reports do not describe the condition of every component if it's in excellent shape, but should note every item that is defective or needing service. The serious problems are:



  • Health and safety issues

  • Roofs with a short life expectancy

  • Furnace / A/C malfunctions

  • Foundation deficiencies

  • Moisture / drainage issues


A home inspection should allow a buyer or seller to be aware of problems and hazards before it’s too late. New construction home inspections give the buyer peace of mind that the builder built your future home properly.  Home inspections are an important step in protecting your investment.  Evan Bair can help save you money with a Texas home inspection.  Evan Bair is based in San Antonio, Texas.

Conducting a Mold and Indoor Air Quality Inspection

In order to successfully conduct this inspection, I would need to be free of pressure from the others involved in the argument regarding where there is or was fungal contamination, and who is to blame for its presence. I would tell them all that the inspection would be conducted in an organized manner, following my checklist and personal observations during the initial walk-through. Since I have already seen suspect water stains on the living room ceiling and behind the toilet in the bathroom, obviously I am going to test these areas. I would have made a mental note of what the tenant told me regarding past contamination. I’ll be checking there anyway.

Having completed a walk-through, I have determined where samples should be taken, have set my equipment on the floor and am ready to calibrate the Zefon Spore Trap Sample Pump. I continue by extending the tripod to the five-foot level, screwing the tripod to the bottom of the pump and attaching the calibration cylinder and hose assembly. Then it is necessary to adjust the pump and allow the calibration cylinder to find the proper level as illustrated in the RES-COM Training DVD, Title Seven.

After completing the calibration process, the next step is to proceed to the location of the first air sample I will collect. If the weather is dry and warm, and the wind somewhat calm, I will first sample the air outside, twenty to twenty-five feet from the front door of the home. This will give me an air sample that is not affected by air flowing into or out of the house. If the air were damp and cold, I would wait until after indoor air sampling was complete to take the outside sample, with the thought in mind that to wait longer would give time for the temperature to raise outside, and the sun to dry things out somewhat.

Next, I would collect an air sample inside, in the living room, at the Zone of Inhalation, approximately five feet high. That room is where I saw the visible water staining on the ceiling. After this sample, I would go to a room such as a bedroom and collect a sample at the height of someone sleeping in bed, a different zone of inhalation from the first. My next air sample would be collected from a wall cavity at the point where the tenant was concerned about mold. The most obvious to me would be under the kitchen sink and I would be able to do this by removing the closest switch or receptacle plate, in this case the one dedicated to the garbage disposal and dishwasher, under the sink. I could run the tubing into the receptacle box, toward the knockout hole in the back of the box, as shown in the RES-COM Training DVD, set the Zefon pump for two minutes and collect the sample from this wall cavity. In addition to collecting a sample from this suspect wall cavity, I would also take one from a “clean” wall cavity, to compare a clean space with a suspected contaminated one. In addition, I perform a water test at the kitchen sink, running first the hot water for five minutes, then the cold water for the same amount of time and inspect for any sign of leakage under the sink, at the drain and water supply lines, as well as the angle stop valves. I shine a flashlight up at the bottom of the faucet assembly and around the rim of the sink to discover if there is spilled water leaking through those areas, indicating faulty sealing around the sink.

After performing these wall cavity checks, I proceed in a linear manner, left to right, top to bottom, through each room, checking for any other sign of water intrusion at windows, ceilings and any other possible place water might enter and be wicked into wood or drywall, causing mold to develop. When I go into the bathroom, I test the wall behind the toilet with my moisture meter, to determine if the staining I had noticed earlier is wet. If it is, and there appears to be any mold, I will collect a tape sample from the flat surface of the wall, put it in the Ziplock bag and label it in the following manner:
Bathroom Wall behind Toilet
Wall Sample
Date
Address of Property.

I took these labeling instructions from the aforementioned RES-COM Training DVD.

Going back to the living room, I want to determine if the stains on the ceiling are wet or if there is mold growing. First, I sample the area of suspect stains by collecting a tape sample, following the procedure for using fresh latex or vinyl gloves, clear scotch tape and Ziplock baggies and labeling as explained above. If there is suspect staining at the ceiling intersection with the wall, where a tape sample could not be taken, I would then use the sterile swab to sample that area. It would then be appropriate to test the stained area with the moisture meter to determine the possibility of recent leaks, and climb into the attic to inspect the area to see where the leak originated. It could be from the roof, a condensate line, a plumbing line running between floors (if there is an upstairs), or any number of similar scenarios. The key is to determine the cause and note it in the report.

If the stained area is wet and it appears there is mold growing, and if there is an upstairs room overhead, I would take a floor cavity sample with the Zefon pump, in order to have the lab determine if mold is growing in that cavity.

At this point, I have collected the following samples:
1. Z1 (Zefon Spore Trap Sample Pump) – outside air sample.
2. Z2 – living room air sample.
3. Z3- bedroom air sample.
4. Z4- wall cavity air sample- under kitchen sink.
5. Z5- wall cavity air sample- clean- inside wall of bedroom with no apparent water intrusion.
6. T1 (Tape or surface sample) - bathroom wall behind toilet.
7. T2- surface sample- living room ceiling staining.
8. S1- (Sterile Swab sample) - living room ceiling/wall juncture.
This would conclude the Mold and Indoor Air Quality testing for this scenario.

Conducting a Home Inspection

Before arriving to begin the inspection, I would call and interview the customer, with questions pertaining to the property history, past maintenance issues, defects and repairs that have been made. With this information, I would be able to prepare for and conduct an informed and professional home inspection.

Arriving on site, my first task would be to inspect the exterior of the house, beginning at the left looking from roof to ground, left to right. I look for missing or broken shingles, holes in the roof and missing or broken roof jacks. I also want to try to determine the roof’s age and whether the present shingles are a second or third layer. Wood shingles should not be used as an underlayment for asphalt-based shingles due to possible deterioration of the wood and possible over stressing of the roof framing because of the extra weight. I would also check eaves, soffitts and gutters for signs of water leaks and resulting rot and damage to the wood or rusty metal. This part of the inspection would also apply to flashings and step shingles around chimneys or angled roof lines over another, lower roof. On the north side, I check for moss growing at shingle edges which can retain rain water so it seeps back into the eaves, causing possible rot and damage.

Looking at the siding or stucco, I want to see at least four inches of clearance between the lowest siding line and dirt or grass to preclude the entrance of termites or other wood-chewing pests their ability to enter the house framing. This separation also provides a buffer zone to mitigate water intrusion at the sole plates of the house structure. I also want inspect for cracks in stucco that might lead to water intrusion behind it into wall framing. It would be particularly important to use a penetrating-type moisture meter such as the Delmhorst BD-21, with long pins, to check stucco called EIFS, since it is very susceptible to water intrusion.

Continuing around the house, I inspect walk ways and driveways for trip hazards, large cracks other than at expansion joints, as well as evidence that foundation cracking has caused settling away from the wall framing. In this same light, I want to know if the house has been built on Expansive Clay, which requires consistent water management around the house due to its propensity to contract and expand with wet and dry periods.

Next, I inspect porch and patio columns for dirt or concrete contact and the resulting rot and deterioration. I look for rotted fence posts and framing members on wing fences. If the house is on a raised foundation, I inspect for adequate foundation vents that are intact and will not allow vermin or other pests under the house. It is important also to note the presence of tree roots too close to the foundation or branches too close to windows, walls and roof.

These can have a deleterious effect on the house both above and below the ground. I also will have inspected the electrical main panel to ensure breakers or fuses are installed and not tripped or burned, and that there is an adequately sized service to the house.

At the entry to the home, I am prepared to put on shoe covers and in every way respect the owner’s privacy and personal belongings. First, I inspect the door, jamb, threshold and entry flooring for signs of damage, water intrusion and suspect mold or stains. Proceeding, as always, from left to right, I inspect the ceilings, walls and floors for stains, drywall cracks, damage or anything that would be hazardous to the health and welfare of the occupants. Digital photographs are helpful in recording such damage and water intrusion. It is also imperative to have written or voice-recorded notes of what I have inspected and found, in order to facilitate a complete written report.

If suspicious stains or water marks are found on ceilings or under window sills, I would use my moisture meter to determine if there is reason for concern in these areas. It would be best to use a non-penetrating type of meter in these cases.

Proceeding on through the house, as I see a fireplace, I know that most states require that the fire box and chimney be inspected by one who specializes in this venue. However, I can look to see if there is a smoke shelf, and check to see if the damper opens and closes properly. I can also look for cracks in the mortar of the fire brick, or if there are broken or missing bricks. My other main concern here would be to ensure a solid hearth of adequate size and proper material to ensure cinders did not fall on combustible materials. I could not find any size specifications on the internet, but as I remember from having built my own home several times, the hearth should extend out approximately 18 inches from the fireplace, and extend 12 inches on either side of the opening.

I also inspect doors, hinges, locksets and other hardware as I proceed from room to room, to ensure they all open, close, lock and unlock as intended. I pull back blinds at windows enough to check for signs of water intrusion and resulting wood rot or mold. If personal belongings block access to anything I normally would inspect, I note the lack of access on the report as the reason such things were not inspected. As Don said in the RESCOM training video, “There is no inspection that…is going to insure…every single item has been inspected sufficiently…that you have personal contents, furniture, et cetera, that make it impossible physically to see every square inch of the inside and outside of a home…” Thus, there will probably be items not inspected, but I still look for damage, water stains or other suspect staining or mold.

In the kitchen, I check under the sink for evidence of past leakage at the trap, dishwasher connection to the disposal and stop valves and water supply lines to the faucet and dishwasher. Then I turn on the hot water for five minutes and again check for leaks, then the cold water for five minutes also, again re-checking for leaks caused by the running water. While inspecting under the sink, I look at the duplex receptacle which services the dishwasher and disposal and determine that the socket for the disposal is switch-controlled, and that the dishwasher socket is not. In the kitchen also, I inspect the installation of the cabinets for safety and security and move on to the next room.

In each room, I look from left to right, ceilings, walls and floors, to discover any damage, staining, water intrusion or mold.

In the bathroom(s), as in the kitchen, I perform the water test and check for leaks. In addition, I want to know that the shower pan and/or tub are free from cracks or other damage which could cause leakage. At this point, I would also inspect tile grout for continuity and try to determine if any of the tiles are loose, indicating that water has seeped behind the tile and degraded the sheetrock. I also want to see that faucets, spouts and shower arms are securely installed and that caulking is complete, with no gaps, to preclude any chance of water damage and possible mold. I turn on the exhaust fan to ensure that it is working properly to dispel humidity when tub and shower are in use.

In any room, I check to see if repairs have recently been made which may cover past damage. This one of the items I would have covered in the interview with the client prior to starting the inspection. I also want to check for smoke alarms in each bedroom, hall and living room, as required locally, and press the test button of each one. Next, I would check to see where the attic access is located and also the crawlspace access, which sometimes is inside a house, but mostly outside. In addition, most homes in this part of Utah have basements, which mean inspecting the stairwell and door for proper fire-rated installation (five/eighths sheetrock and steel door with good sealing). I am to realize that RESCOM has additional charges for further inspection of crawlspaces and attics.

After all rooms and the exterior have been inspected, if mold and water staining are found, I would recommend that a Mold and Indoor Air Quality Inspection be performed.

This would conclude my inspection.

Buying A Home

When you set out to buy a home, probably the largest purchase you will make, you want a number of things clearly settled in your own mind. These may include:

  • Did I receive desired value for what I spent?
  • What is the general condition of all the elements of the house?
  • Was my inspector thorough in his inspection?
  • Was my inspector knowledgeable? Truthful?
  • What is the life expectancy of the various systems of the house?
Let me give you some important information about this last question regarding life expectancy. Did you know that oak or pine floors should last a lifetime? So, also, slate flagstone, terrazzo tile and marble. Carpeting should last up to 11 years, depending on traffic, carpet quality, pad quality and installation1.

I have seen wide pine floors in homes in the Eastern US that were 150 years old or more and still looked reasonably good. Check in tomorrow for further information on this and other Home Inspection Topics from “The Reliable Source”, Evan Bair, your hometown Inspector.
