"Foundation repair- maybe? but the work was crawl space french drains hooked up to a sump pump that tied into an oudoor downspout for drainage. All was performed professionally & I am satisfied with the results."

"I hired them for some spray foam, but once they got into the space, they discovered that the work that they needed to do didn't need to get done. They could have just done the job, but they let me know that it wasn't needed. Such honesty is greatly appreciated. If I need some work done on the foundation or attic, I will most certainly work with them again. They are courteous, communicative, and provide excellent service. Simon was fantastic to work with."

"Called seeking a repair of a 1/2" copper water line leak in a bathroom wall. Called back immediately. Came to the house the next morning and cut out and replaced a section of pipe in the wall and under the house. He was in and out in about 1 hour."

"They came out and changed the filter system and tested the water."

"From the very beginning, their GM, Steven Kern, suggested options for the cabinetry that would be more aligned with my budget; so, rather than replacing or refinishing cabinets, we discussed adding crown molding instead. They had molding that matched my "spice maple" cabinets perfectly...including a corner section that was slightly darker than the rest. In addition, their designer and reviewed a wide range of flooring, glass front and backsplash options, and she gave me a few samples to take home so I could see them at home under different lighting...she even found a few medallions left over from another job that she thought could be great focal points behind the stove. In addition, the installation crew was friendly, on time, and efficient as well. In the end, my project came in on time and WELL UNDER budget...and it's gorgeous!"

"Bob came to the house when promised. Due to the pictures I took of the equipment at his request, he had all the parts that may be needed. He pulled the bladder apart and showed me the clogged tube and switch. The bladder was the original in this house, aged 43, so it was a mutual decision to replace both. The new equipment was a perfect fit and was up and working quickly."

"In early December 2018, I discovered mold in our crawlspace when replacing some fallen insulation. I called several mold remediation/encapsulation companies with Kefficient being one of them - based on their reviews on Angie's List. Mark (the owner of the company) called me back almost immediately, asked some follow-up questions to get an idea of the scope of the project, then set up an appointment later that week to do a full inspection of the crawlspace. He ended up coming out on a Sunday to do the inspection. After completing that, he came inside and discussed what he had found, the best way to remove the mold, prevent its recurrence, and encapsulate the crawlspace. Mark took a great deal of time to explain every step of what he was going to do and why he was going to do things in a particular way, answering all of our questions, and never tried to "make the sale" as some companies do. Both me and my wife very much appreciated his approach and that there was absolutely no pressure to sign a contract with him. On a side note, we had been burned by a contractor years before on adding a screened porch. As a result, my wife in particular is very hesitant to hire anyone do work on the house. The fact that she was ready to hire Kefficient after that initial meeting speaks volumes to Mark's genuine and honest approach. The next day, Mark emailed his proposal to me. I emailed him several times with additional questions and he responded to all of them very promptly. But before signing the contract, I asked to meet with him once more with some additional questions and he was more than happy to oblige. He must have spent easily another hour with us that second time. And even after signing the contract, when I would email Mark with additional questions that came to mind as I did further research on crawlspace encapsulation, he was always very quick to respond with the information I had asked for - from material specs to building code requirements. Mark was able to begin the project earlier than anticipated. It started with sealing the crawlspace vents and installing a temporary dehumidifier to dry out all of the joists and beams prior to mold removal. He came by a couple of times to check on the progress to make sure that the humidity was low enough to make the mold removal effective. Once it was, he and his partner removed all of the insulation between the floor joists, fogged the crawlspace with mold killer, then cleaned all of the exposed wood. Just that alone made a huge difference. They then sealed all of the exterior penetrations with expanding foam, attached foam board insulation around the entire perimeter, installed new fiberglass insulation in the joist spaces along the sill, sealed all of the subfloor penetrations, removed the old crawlspace liner, wrapped all of the piers, installed the new 16mil vapor barrier, installed a permanent dehumidifier, and replaced both access doors/frames with new ones made from pressure treated wood that are insulated as well. Once they began, most of the work was done within about 5 days. However, due to weather delays beyond their control - rain, snow, freezing temperatures - it was January after all, they were not able to install the new access doors until a few days after that. But during the entire time they were working, Mark would update me via email or text on the progress of the job and the timeline of what was left to be done. Mark was exceptional on this point. At no time did I ever wonder about what was being done or when the remaining tasks would be completed. The finished product looks amazing! Kefficient did a fantastic job removing the mold and encapsulating the crawlspace. And the attention to detail throughout it all was impressive. Mark made sure that everything was done right and done well. He's even touched base a month later to see if I had any new questions or concerns (not a single one). If only every contractor worked the way that Mark and Kefficient does!! I would absolutely recommend Kefficient to anyone that needed this type of work done."
