Buying property is one of the most important decisions you’ll ever make. Before you sign on the dotted line, be sure your investment is a good one. The professional building inspectors at LESA Inspections can provide you with the assurances you need to move forward in your real estate transaction with confidence.

"Do not work with LESA. I am the first to write a positive review and try my best to avoid negative, but LESA's negligence has cost my family $26,000 in unexpected repairs after our home purchase. Choose a different inspector. First, our entire basement ceiling/floor system was contaminated with a light fluffy mold. It was discovered by another specialist after our home purchase. My husband remembers asking Simao what it was during the inspection, and he said the basement was so dry it must be dust. The remediation cost us $16,000. Today, we had an HVAC company come out to service our boiler. Simao had told us during the inspection that it was old, however we could expect to get at least 1-2 years out of it. Our HVAC company immediately told us our unit is not even safe to use and needs to be completely replaced. This will cost us at least $10,000. After purchasing a home, these types of surprises are the last thing you need. Do yourself a favor and go elsewhere - please."

Septic Tanks questions, answered by experts

If you’re going away on vacation or leaving your home for a long time, it’s a good idea to switch off your well pump and pressure tank before you go. This way you can prevent any damage from unexpected leaks that may occur or unforeseen electrical issues while you’re away.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too. 

Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability.

It’s not needed for your septic system to operate, but it will make regular maintenance and the ability to access your tank infinitely easier. You’ll likely also save some money in the long run, not to mention a lot of labor and energy because there will be less digging involved to find the tank when there’s a riser installed.

Modern septic tanks have two lids: one that covers the inlet where wastewater flows into the tank and one that covers the outlet where the treated water flows out to the drain field. However, older septic tanks installed before 1975 may have only one lid. Because septic tanks last 20 to 40 years, if yours only has one lid, it may be time for a replacement.
