Good job guys, thanks !

I had some issues with my basement leaking when we get a heavy rain. I called Kefficient and they responded very quickly and professionally. I was really pleased to see that they were on time through the whole job. They did what they said they were going to do and did it within my budget.
When they left I could not tell they had even been here.
Good job guys

We REALLY appreciated the honesty we got from Mark.

My husband and I were having some issues in the basement that we thought were going to be very expensive to fix. We were expecting a few thousand dollars at minimum! We emailed Kefficient so that we could get a quote from them. The whole process was very quick. Mark came out and went under the house with my husband. He went over the crawl space top to bottom with him, explaining everything he was looking at or looking for. Turns out we didn’t have a big problem. It was a very cheap and quick fix. We appreciate the very courteous treatment we got. We REALLY appreciated the honesty we got from Mark. Most companies these days just try to take as much from you as they can. It was just a great experience all together!

Mark and his team did a fantastic job

Mark and his team did a fantastic job resolving our crawl space issue. We were in a bit of a crunch time-wise because the work was part of a real estate transaction, and Mark was able to fit us into his already busy schedule. We couldn’t be happier with our experience with Kefficient and highly recommend them.

Mark is the best contractor and his crew the best work crew that I have ever employed for any work.

Mark and his crew just completed doing a tremendous job encapsulating and repairing my water damaged crawl space. Twice this year I have flooded floors on the lower lever. Mark diagnosed the issues. He pointed out specific problems and how to redress them. He knew about the necessary permits (other estimators did not mention them) and got them in a timely manner. He described the steps involved and the mold remediation process. The work crew (Mark, Sarah, Tyler, Issac(?)) worked diligently and efficiently spending days in the crawl space doing the required work. Everyone was courteous, efficient, and helpful in explaining what they were doing on any given day. The communication with Mark as to schedules and timing and anything having to do with the project was excellent. I would highly recommend Mark and Kefficient for any crawl space or waterproof situation you may have. Mark is the best contractor and his crew the best work crew that I have ever employed for any work.

Project was executed flawlessly with premium materials and an extremely high degree of craftsmanship

After obtaining 4 competitive quotes to encapsulate our crawl space, we decided to award the job to Kefficient and we could not have been more pleased with their work. Unlike their competitors, Kefficient’s work proposal included all items we researched as being best practice such as for example drying out the crawl space before mold remediation. Kefficient also ensured that their work is permitted with the county, which is a great assurance that the encapsulation work is done right and will positively impact property value should we ever have to sell our house. Kefficient communicated very well with us and all personnel was professional and polite. They would not close the project before we were completely satisfied and even addressed a problem that was outside of the work scope without charging extra. We were probably more involved than the average homeowner in the encapsulation project and accompanied the crew on numerous occasions in crawl space tours to ask questions related and unrelated to the encapsulation project. The crew discussed and advised us on all questions and made sure all our concerns were addressed. Overall, the project was executed flawlessly with premium materials and an extremely high degree of craftsmanship that we are 100% confident their three competitors we obtained quotes from could not have matched.

I highly recommend them

Mark and his crew are one of the most professional contractors I have worked with over the years, and I have worked with many over my own professional life in commercial and industrial facilities maintenance, so i’m well versed in what it takes to hire contractors and ensuring that a job is done on time, in budget and with professional results. They are very professional in their work in all ways, everything about this company is spot on, everyone is very professional in demeanor and character, they are diligent about doing the job professionally and the end results are top notch, as we used to say when I myself was a contractor, “they do pretty work” everything about my project when smoothly and efficiently, and the humidity in my crawl space is being controlled within +/- 1% of set point, and maintains set point with minimum operation of the dehumidifier, most excellent. I highly recommend them with no reservations.

Mark and his TEAM did an excellent and thorough job

Mark and his TEAM did an excellent and thorough job encapsulating our crawl space and installing the dehumidifier. They did not speed through the process and explained each phase of the progress. We had several questions about the process and benefits of encapsulation and they all took their time explaining in detail. I would highly recommend them!!

This is an extremely ethical company that does excellent affordable work.

Kefficient Company installed a drainage system in my basement this March. Mark Keffer in a week’s time changed my basement from a damp place where water invaded at every storm into a dry area with water going away from house! Mark is a a compassionate professional worker who explained the project to me. Mark and Tyler did everything they could to protect the rest of my home from dust and dirt. My downstairs is now a warm, comfortable area that is dry and protected from rain and storms. I highly recommend Kefficient to do water drainage work. This is an extremely ethical company that does excellent affordable work.

The crew at Kefficient did a wonderful job

The crew at Kefficient did a wonderful job remediating moisture issues and encapsulating our crawl space. They were incredibly professional. They worked clean every day and communicated with us every step of the way. One of the greatest things was their reassuring manner in dealing with something that we were extremely concerned about. I would highly recommend them to anyone.
