Basement dehumidification – Humidex

As a home inspector I often visit home that have a basement ventilation system, a common brand is Humidex. I’ve never talked to anyone that has experience with them that has not liked them. They pull cool moist air from the lowest level at the basement floor and exhaust it out of the house. As a result you get an air exchange in the basement from the floors above, which is usually a welcome thing. Basements do not get much in the way air exchanges. Pulling the cooler and moister air out of the basement has a dehumidifying effect. They are cheaper to run than a conventional dehumidifier because there is no compressor to operate, just a fan. As a result, I’m a fan of the Humidex system. Lots more at

Wet Basements

The national statistic is 90% of wet basements are due to grading issues around the base of the foundation. In order to get rid of the water in the basement in these cases is to simply put more dirt around the foundation and grade it away. The correct slope for the grade is 1 foot of drop for 1 foot of run – in other words, if you are standing 6 feet away from the foundation you should be six inches lower than the foundation. The good news is dirt is “dirt cheap”, and the work is not difficult. It is also important for the roof gutters and downspouts to be functioning correctly and leading the water away from the foundation.

Unfortunately, many unscrupulous basement waterproofing contractors make a bigger deal of water in the basement so that they can sell a “French Drain” system and make more money. There’s nothing wrong with French drain systems because they do work. But why spend the money ($7,000 to $20,000) on a drain system unless you have exhausted the most economical route (fixing the grading problem by putting more dirt around the foundation). By the way, the best type of dirt for this purpose has a higher clay content then normal so that it deflects the water rather than allowing it to drain through towards the foundation.

If you fixed the grading around the property and water is still coming into the basement, the next thing to do is seal any cracks in the foundation wall. Sealing these cracks should be done with a flexible material such as caulking because there will likely be more movement in the crack in the future. The other approach to fixing cracks is to use an epoxy type glue to solidify the crack and make it so that the crack cannot move in the future.

If you fixed the grading and sealed all the cracks and water is still coming into the basement, a French drain system may be your best alternative. The water proofing contractor will cut a trench around the perimeter of the basement floor and install pipes with holes in them in the trench all sloped towards a sump installed in the basement floor along with a pump. The sump is basically a collection tank where the pipes drain the water below the level of the concrete floor. When the water level gets to a certain point the sump pump turns on and pumps the water up and out of the basement. After the pipes are installed in the trench a new layer of concrete is poured over the pipes, except small crack is left between the wall and the basement floor slab to allow water to drain off of the wall and into the pipe. Water has no choice but to enter the pipe and travel (by simple gravity) to the sump pump where it will be pumped up and out of the basement. These systems do work and can make a wet basement dry.

Home Inspectors should not provide a financial estimate in their report.

Someone just shared an inspection report with me from an engineer that said the house needed $125,000. Of course now the buyer wants $125,000 off the deal. The inspector is doing everyone a disservice because it’s throwing things out of perspective. It’s ethically wrong. Some inspectors do this to get a second or third inspection with the same buyer. They are not buying a new home; they are buying a used home. If they want to bring it into like new condition they should have a general contractor do an estimate based on what the buyer wants, not what the inspector wants. http://www.safeharborinspections.com/

Inspections don’t pass or fail

A lot of people think there is a pass/fail in home inspections (including some home inspectors). There should be no pass fail – the purpose for the inspection is for the buyer to understand what they are buying. The inspector should explain things in a calm, cool and collected manner and not get involved in advising the buyer to buy or walk away…NEVER. The buyer has to make that decision once they know what they are buying.

Check your chimney regularly

You can’t be too careful about chimneys. A bad chimney caused a house to burn down in Huntington over the holidays. Get your chimney cleaned and checked by a chimney contractor.

The Right Shingles for the Right Roof

Roof Image

To the untrained eye, looking at this roof from the outside you would not likely see any big concerns, correct? However, there is a concern and a problem. The main section of roof has a normal slope angle so that water, snow and ice can readily run down the roof without causing an internal leak. But the lower section of roof has a lower slope angle which requires different roofing materials at the installation stage. The roof material shown here is standard “three tab fiberglass/asphalt” shingles. These shingles work well on a normal slope roof, however, they are not designed for low sloped roofs; they can allow water entry as a result of wind driven rain or snow/ice melt backing up into the shingles and leak into the structure unless a proper underlayment or waterproofing membrane has been installed below the shingles. In this case, the roofer did not take any special precautions and simply laid tar paper below the shingles, and tar paper is not good enough. A heavier duty, better functioning waterproofing membrane is necessary on a low sloped roof such as this. At the outset, the roofer also could have chosen a different roofing material other than the three tab shingles. A better choice would have been a rolled roofing material that comes in large rolled sheets and is specifically designed for low or flat roof applications.

Roof Leak Water Damage

Caused by using the wrong roofing materials, the water damage depicted here, is a result of using the wrong type of shingles. The repair requires a "ripoff" of the current roofing shingles and the proper ones installed.

As you can see from the interior photograph, this roof has in fact been leaking and will likely require a “ripoff” of the existing shingles and reinstallation of proper materials in order to make the roof waterproof.

Oil Burner Inspection

Oil Fired BoilerThe picture on the top shows a typical oil fired circulating water boiler that looks completely normal. However, upon further inspection we were unable to locate a temperature-pressure relief valve. This valve plays a very important safety role in the operation of the boiler: if the controls of the boiler fail and the oil fired flame continues for an extended period of time, excessive pressure can build up in the boiler but be safely relieved by the temperature-pressure relief valve. But in this case, it was missing!

Often we see a leaking temperature-pressure relief valve which is caused by either a failed expansion tank or the valve itself needs to be replaced. In this case, it appears that the valve was removed and an expansion tank was installed (see the second photograph). Unfortunately, this condition could lead to a substantial explosion of the boiler!

During our inspections we often see amateur work, and this is an example of very dangerous amateur work!

Amateur Work!

An example of a support beam done all wrong.

We see amateur work regularly during our inspections. Here is an example of amateur work that could have substantial consequences to the structure of the home. First of all, the steel Lally column is not straight.

Secondly, because they didn’t properly install the steel Lally column, they made up for it with small chunks of wood. Obviously, this is not a stable condition which could have disastrous effects to the structure above. In this case, the main beam could substantially dropped or even collapse!

Way too many people take on work which they are not qualified to do. This regularly occurs in plumbing, electrical and structural installations. The amateur work jumps out during an inspection, and even a layperson can see the poor workmanship involved. The moral of the story is: don’t do work on a piece of real estate unless you know what you’re doing!

Plumbing Traps – Home Inspection

The purpose of a plumbing trap is to stop sewer gases from entering the home.

Plumbing Trap

The trap collects wastewater at the bottom of the U-shaped trap and prevent sewer gas from backing up into and through the plumbing device and ultimately into the home. Whoever installed this plumbing trap didn’t understand the conceptand the consequence is a very smelly and even potentially dangerous room filled with methane gas. This is another example of amateur work!

Sometimes we enter a basement and it smells of sewer gas.

Substantial Termite Damage – Long Island, New York

A substantial amount of termite damage

Sometimes termite damage is very substantial and requires major structural repairs. These photographs were taken in a home where termites were having a Thanksgiving meal every day for decades. The termite species we encounter in and around New York City and Long Island are Subterranean Termites. Fortunately, damage from Subterranean Termites occurs very slowly. However, if left untreated over the years, the impact can be quite expensive, as was the case in this house.

more substantial termite damage

All of the floor joists and the sill plates had to be replaced in this home. When my client asked me how much it would cost to make the needed repairs, my response was “I don’t know”, you must get a contractor to price out the repairs. She said that she had a good friend that was a general contractor. A few days later we had the answer and it wasn’t pretty. The contractors estimate was $50,000. As a result, the buyer decided against purchasing the home.A screwdriver through a beam that was ruined by termites
