"He responded to our initial inquiry promptly. Showed up on time to do the job. Very neat worker and left everything perfect. The next radon test came back extremely low so it works perfectly. I highly recommend him."

"Ben was on-time, efficient, professional, courteous, and informative. I recommend that you specify him for your radon mitigation job."

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."

"The gentlemen were kind, courteous and respectful. As I mention above, my slab was 8ft by 16 ft. Along one 16ft edge, the slab had dropped by about 4 inches. I don't know when it was installed, but I would guess it was part of the original construction (1954), and was enclosed probably in the 70s. The gentlemen arrived with 1 2ft bubble level and 2 digital levels which were perhaps 1ft in length. From there, they proceeded to place their 2 ft level so that its end touched the 16ft edge, the opposite end parallel to the 8ft dimension. They raised the level so the buble was centered and marked the adjacent brick wall about 1 inch up from its base. Did I mention the slab is 8 ft wide in the parallel dimension to their level? Did I mention the slab had dropped about 4 inches along that 16ft edge? I suggested they use my 4 ft level instead, which they really didn't, relying in their 2dt and 1ft levels instead. They raised the dropped edge about 2 inched, and the whole slab about one inch, resulting in the edge which was down 4 inches, being down only 3 inches now. At this point, cracks began to precipitate in the slab, so they suggested we stop, which I agreed. Then they suggested my 4ft level was inaccurate, and that their 2ft level was more accurate, reporting the slab only slightly out of level. At that point, I stacked their level on top of mine, and demonstrated that their level centered the bubble before mine did, but when my bubble was centered, so was theirs; their level was inaccurate with respect to mine! In the end I was told that, once the foam was fully cured, I could get a subsequent leveling. Unfortunately, they had no more open appointments until March. Meanwhile, that slab was under my laundry room, which I removed, temporarily supporting the roof with beams on the surrounding ground, and engineered joists. Since I'd rather wash my clothes at home than wait til March, I decided to level the build a floor over the slab instead, as the foundation for the new laundry room structure (enclosing the plumbing for the laundry room might also prove useful when the outside temperature falls below freezing soon). To be fair, when the job was quoted, I asked about the ability to lift the entire structure, and was assured that wouldn't be a problem, so the guy who quoted the job did not know I would tear the structure down. However, he surely knew there was a chance the slab would crack, and that if it did, they would not be able to address the remainder of the leveling until March. My general review is this: * Admit to the problems which could occur up front so that the consumer can make a wise choice, rather than selling the job with promises of making the slab level. I have no doubt that, give the time, they could make it level. But starting the job in October, and finishing it in March is not acceptable. * Have proper equipment and train your people to use it. Showing up with a 2ft bubble level and 1 ft digital levels, then not understanding that the lift indicated by a 2ft level, when brought to level, is only 1/4th the lift needed for an 8ft span is rank naivete on levels and similar triangles. Not knowing that the pinch of the vile, (or likely the curve, in the vile is offset to one edge, as their 2fter was) determines the accuracy of the level was just the final blow for my assessment of their competence. The fact that I wound up doing exactly what I was trying to avoid; build a wooden platform which was level on top of the sloped slab, makes it seem like a complete waste of $1700 to have them come to my house. I only hope that the result of the foam pumping is that any voids under the slab were filled, and that it now has a foundation under it which will not erode further. I am certain they do fine work, and the price I paid was in line with what i was expecting. The workmanship and apparent level of competence, however, was disappointing."

"Very detailed and through inspection. Mark will take the extra time to explain all the details of the report to you. He is a full service inspector who also provides Radon testing and Septic Inspection. It is always a great pleasure to work with him."

"A two-man team worked very efficiently to remove each vent cover and vacuum inside the vent openings throughout the townhouse. One man removed the vent covers while the other man vacuumed inside the vent openings. No problems with how they worked but I think there are other companies who perform a more thorough cleaning of ductwork using other methods. This company did a superficial cleaning and worked very quickly. In and out within an hour.

"The energy audit surfaced some significant issues. That's what we wanted. Shelter Alternatives presented a bid for the job, which seemed high. We are checking with other contractors to complete the work."
