Mr Basement
5.0
Just completed a kitchen remodeling and wanted to insulate the crawl space under the kitchen. Mr. Basement sealed off the vented crawl space and encapsulated the ground up to the rim joints with their "white space" material. Plus, they sprayed foam insulation at the rim joints. Not only did I get in insulated crawl space, I now have additional temperature controlled storage space. They did a very professional job with quality materials.

Excellent - crew was professional and interested in performing the best job possible, didn't take any shortcuts, cleaned up each day, so it didn't look like they were there. Job was estimated to take 3 days maybe out to 4 if they ran into any problems. Completed in 2 and 1/2. Arrived on time Monday the 4th, worked all day. Came back again on Tuesday the 5th and worked all day. Returned to finish up half-a-day on Wednesday the 6th. Randall stopped by on the second day to inspect and to clarify any questions. We can notice a difference already in the interior of the house as far as moisture and odors.

Our energy consultant, Matt Pascual, gave us a clear explanation of the work Comfenergy would do, but he was also accommodating to the few changes we requested. He followed up by giving us his cell phone number and the two times we called him, he answered immediately and attentively addressed our questions. His professionalism influenced our selection of Comfenergy over the other 3 companies that also came out to our house to explain and estimate the job. We were given a work start date and our work crew, headed by Ruben Samper, was there promptly on that date and promptly each of the following days. Ruben was trustworthy, easy to work with, and very responsive to any concerns that we had. He seemed to have an excellent working relationship with his crew and they all worked cleanly and efficiently. The whole job was completed in 4 days.

The gentleman looked over my problem and gave me advice that I am unable to followup on, i.e., ripping out a newly installed floor and encapsulating the crawl space. I will ventilate it instead.

We had talked to other companies about the crawl space and removing the existing old nasty insulation and cleaning up some efflorescence and then replacing the insulation. The tech that came for the estimate upon seeing the crawl space told us he had bad news. We thought that meant the space was is very bad shape.... but no. He told us he could not help us -- not because it was so bad but because the crawl space was in good shape. He explained that although NV Waterproofing does in fact encapsulate crawl spaces, ours was not in need of it. He spent the next 20-30 minutes answering our questions and helping us understand what we should do. He said we needed to actually get the joists and floor boards sealed with spray foam insulation, but NV didn't do that. He was incredibly patient and helpful in answering our questions. If we have any need for their services in the future we will be more than happy to give them a call.

He's very courteous and prompt, and explained everything very thoroughly. His quote was very detailed, as was his plan to encapsulate the crawlspace.

Basement Masters Waterproofing

A home inspection revealed some evidence of previous moisture issues in the crawl space of the home we purchased. In addition to encapsulating the crawl space, we also wanted to replace the sump pump and put in a dehumidifier. After doing a lot of preliminary research online about what each process entailed and getting a feel for prices, I called three companies for quotes. The first called to confirm the appointment, but never showed up, the second was ok in terms of the rep they sent out, but their price was through the roof and the third was Basement Masters Waterproofing. Third time really is a charm! Randall Butterfield called to confirm the appointment and showed up on time. He inspected and measured the crawl space and also looked over the outside of the house to survey how water drained away from the home. He explained how the installation would work and was great about answering questions in a way that was very easy to understand. Within a day, I received a very detailed, professional project proposal that included diagrams and photos that again explained the process. We were scheduled within a couple weeks for a Saturday. Randall had a crew of two with him (Walter and Dennis I think) and all three worked so hard in less than desirable conditions (July heat/humidity in Washington!). They were very respectful of our home and time and did a great job of protecting the floors and cleaning up. After just a few days we noticed a marked improvement in the way our basement smelled and now - a month and a half later - the damp, musty smell is gone completely. I would definitely recommend them to anyone who is looking to encapsulate a crawlspace, replace a sump pump or install a dehumidifier.

Chip Gentile is a dear man......we talked, I decided to go with them after having some nightmare experiences with other salesmen, and it all went according to schedule, the work was done neatly, no problems, and, as far as I know none since....the floor that was warped as a result of moisture seems to be returning to it's and quot;nativeand quot; state. This company gets the highest grade from me.

NV Waterproofing & Foundation Repair

Marketing representative Christian Abrigo explained all aspects of the benefits of encapsulation to prevent and remove mold and the associated odors in my large crawl space. He explained the technical procedure for installation. He answered all my questions about the safety of the product and provided a safety data sheet and references. He was a great guy who went beyond the call of duty to make sure all my questions were answered. Chris was knowledgeable, pleasant and enthusiastic. The installation foreman was also very experienced and knowledgeable. He answered all my questions on arrival and used tarps to cover all the flooring. There was no mess in my house and the install was not invasive or infringing on daily activities. There was no residual odor or unpleasantness after completion. My house and the crawl space were neat and tidy after the installation. Most important, the smell of mold was finally gone from the room above the large crawl space. I highly recommend NV Waterproofing and will use them again for waterproofing in my home. Photos can be provided by Chris of my crawl space before and after as well as other projects so I have not provided pictures with this recommendation.

JES Foundation Repair

Crawl space was 400 sq ft with almost 1000 sq ft of total surface to cover. Overall, the process from inspection to completion was good. JES is very responsive and willing to answer questions at any time. We reviewed three other proposals and selected JES because their inspector brought out several points that we hadn't noticed. The JES repair and encapsulation concept was more logical and one of the less costly solutions. JES also provided a research paper on Crawl Space Science - What to have done and why". We further researched the subject ourselves and found that JES had a better understanding of our situation than the others who tried to sell us a lot more than we needed. We definitely liked their floor material that is 20 mil thick - more than most of the other companies. They also put down a molded plastic underliner that helps keep the liner off the dirt, allows you to move storage boxes into the area a little easier and less fear of tearing the material. You still have to be careful, but this underliner is just another example of JES understanding the reality of the homeowner wanting to use the crawlspace after encapsulation. The workers were on time and stayed until the job was completed. The crawl space had an easy access from a full-size basement door and a two foot wide perimeter to walk on two sides of the crawl space. The workers placed drop cloths across all the floors from the outside door to the crawl space. They even taped drop cloths to the bathroom. The workers were very nice. When I would see how they were coming along, they would explain to me what the different processes were. They left some extra encapsulation material and tape in case we did tear the material. But the warranty is one of the best, if not the best. As we read the science paper, I did notice that the article recommended dropping the encapsulation material below the top of the crawl space so you could notice if termites were active. Since Virginia is known for a dense termite population, we called JES and asked them about the gap that should have been done on the walls. They sent out a technician to cut the wall material and expose the top of the block wall. He also left some of the very strong tape (at my suggestion) so I could make a clean edge along the cut material. As the technician finished, we noticed that the vent covers were cracked. The technician was not far from the main office, went back, returned with two new vent covers, and installed them.

I went on line and requested the free inspection of my crawl space. Lewis called me the same day. He was very polite and down right friendly. He asked me questions about what I would like specifically to look for. He then asked me about dimensions of my crawl space. I was in luck, there was an appointment opening the next day. He let me know that Bill Strong would be coming over at 3:00. Bill showed up exactly on time. He had an intern with him, named Maria. Just like Lewis, Bill and Maria were very polite and down right friendly. ValueDry's policy is to have the homeowner and the spouse available for the inspection. We get that because we believe as ValueDry does that me wife and I need to hear straight from the mouth of the expert as to what proposals might be made. After an initial meeting with Bill and Maria, I showed Bill our two entrances to our crawl space. Bill took a look and took pictures. As he took the pictures, he described to me what he was looking at. After that, he sat down with my wife and I and explained to us the research on how crawl spaces work. He had power point that provided visuals to what he was telling us. My wife had a lot of questions and Bill was very patient with her and answered all of her questions and mine to our satisfaction. He gave us an estimate for the grand total of everything that would need to be done to do the encapsulation of the crawl space. Based on my research on Angie's List, the estimate was very reasonable. We worked some tailored estimates to fit our desires as well. While Bill was talking to us, Maria had been talking measurements of the downstairs portion of the house. My wife and I felt comfortable allowing her to move about the house on her own because Bill and Maria were like friends we had know for a long time. We chose not to do the encapsulation during the upcoming school year, but are looking to next summer to have this done. The whole experience from the initial call from Lewis to Bill and Maria's visit was great!

EXCELLENT! JAY CAME OUT AND GAVE A VERY REASONABLE & KNOWLEGABLE ESTIMATE FOR THE WORK TO BE PERFORMED. THE CREW ARRIVED PER SCHEDULE AND IMMEDIATELY BEGAN WORK. JAY SUPERVISED THE ENTIRE INSTALLATION, ALTHOUGHT I BELIEVE THEY KNEW WHAT TO DO AND THE ROUTINE. THE CREW WORKED ESSENTIALLY FROM START TO COMPLETION WITH SCARCE BRAKE TIME. JAY BROUGHT OUT SEVERAL TYPES OF WALL DRAIN FLASHING TO MAKE SURE THE RIGHT TYPE WAS AVAILABLE FOR WHATEVER WAS APPROPRIATE. IT TOOK MORE TIME AND EXPERIENCE TO DO THE INSTALLATION, WITH NOT HAVING TO CUT OFF THE BOTTOM OF MY FINISHED WALLS. A SECTION OF PANELLING HAD TO BE REMOVED TO INSTALL THE SUMP PUMP DISCHARGE PIPE AND JAY TOOK THE TIME TO SECURE THE CORRECT COLORED NAILS TO REINSTALL THE PANEL. THE CREW WAS POLITE, INFORMATIVE AND RESPECTFUL OF MY HOME. THE PRICE DID NOT CHANGE FROM THE ESTIMATE!

Excellent work! Arturo helped us originally followed by his amazing crew. Highly recommend this company. Arturo as consultant, Jeff as Project Manager and Hymie we’re all excellent. Our crawl space foundation was disgusting. This work should have been performed by earlier owners but it fell to us. We were tired of critters, cold floors in the winter, and moisture. Now we have a space under our house that is immaculate and dry. And, cracked wooden beams have been stabilized and a de-humidifier Installed that drains invisibly.

Rnadall Butterfield contacted me about providing an estimate, showed up on time on the day specified, and gave me an extremely competitive price. He was great to work with throughout the process and was extremely nice to my kids (he even let them read him a story). He was helpful with pros and cons regarding different options, and I valued his expertise. His workers showed up on time on the day specified and even stayed late so they could complete the project in one day. I was impressed by the professionalism of everyone I dealt with at the company.

.Three man crew were right on time. Friendly, professional and efficient. Although scheduled for two day installation, the crew worked a little longer and finished all tasks and clean up in one day. Excellent crew that worked with me in all my questions and recommendations. Would recommend to anyone. The total price was a bit steep but, I guess you get what you pay for - top notch results.

Jay, the inspector/salesman did not listen, he just wanted to talk. Was a complete know it all. I wanted someone over to address a specific situation and all he did was try to sell an almost $19,000 encapsulation system. The guy was so bad that other workers for the fireplace I had over were questioning who this guy was based on his demeanor, attitude, lack of professionalism and the fact that Jay told the fireplace people to stop working so he could talk. Thought I was getting a knowledgable crawl space inspector, but instead got a blantantly terrible salesman. He couldn't even measure the humidity because his battery was dead and then he proceeded without permission to remove and check all the smoke alarms for a 9 volt battery and then when he couldn't find them there, he started literally rummaging through our personal items which were in open boxes to find a battery. After all that, he still said, well it feels like there is more than 50% humidity down there. I needed someone to look at the existing vapor barrier in a particular location in the crawl space, however Jay spent all of 5 minutes down there and didn't even crawl to the area. He just took a picture of it. When he came out and I started asking questions about what he discovered, he acted like I had no right asking him anything and kept asking me to watch his stupid videos. And then he wrote up a ridiculous quote for $18,000+.

First, they insist that both homeowners be physically present for the "inspection." (Which was not an inspection at all, but more on that later.) My husband took time off, and when I offered to join the meeting by phone they would not schedule the "inspection" until I absolutely agreed to be present in person. Otherwise, they would be forced to charge us several hundred dollars for the "inspection." So, we started with me taking time off from work and rearranging my schedule to accommodate them. I have never, in all of my times of having work done on various properties, had a contractor that was so inflexible with this requirement. In my opinion, who meets the "inspector" and how we decide to proceed on work on our property is a matter between my husband and myself, and a company has no business dictating how we as partners handle that. That should have been the first red flag. Then, the "inspection" turned out to be a little lesson on crawl space encapsulation (vs a ventilated crawl space), and a very hard sell. We barely got the guy to poke his head into our crawl space to take a look, and that after the hour of the hard sell. Then it made sense; they called it a crawl space renovation and attached a rather high price tag to it. I can see how both homeowners would need to be present to sign off on 3-4x more than they were expecting. It's a sales pitch all the way. When I tried to suggest that we keep the crawl space as "ventilated" and just replace insulation and provide a vapor barrier, we had an argument that that was really a stupid idea and it became clear that they really only had one expensive solution. The salesman said that they could replace the insulation between the joists and provide a vapor barrier (essentially leaving it as a vented crawl space) if we really wanted to go ahead with that inferior solution, but the quote he provided listed the work as basically an encapsulation where the homeowners would go back in and add insulation in between the floor joists. If it was truly an encapsulation, there would be no need for us to add insulation. I couldn't make heads or tails of it, and it made me think they only do encapsulations of crawl spaces and cannot offer an alternative solutions. The irony is that after that experience I started reading about crawl space encapsulation. While I do not agree with the salesman's opinion that this is the only workable solution, it does seem like a good solution in many cases. But the audacity to require both homeowners to be physically present, calling what was clearly a sales situation an "inspection" that we would be required to pay for if one of us didn't make it in person (!!!), and the high pressure to sign off on a high price tag turned me off to this company and their business practices. I would caution others to stay away.

Randall Butterfield and his crew are TOP NOTCH! Unlike other companies, Randall gave us an honest assessment of what was required to do the job right. We needed our crawl space leveled and a new barrier in the basement (encapsulation) put in. This was not an easy task given the small amount of room his crew had to maneuver around in our basement. Like clockwork, the workers arrived on time and completed the job in three days. Upon completion, the work area was left spotless. I highly recommend you consider Basement Masters Waterproofing!

We had noticed some things that could indicate foundation issues. Rob Gold came out and assured us that no foundation work was necessary. He did note that we should have our crawl spaces encapsulated, and we are strongly considering it. If we do, we are certainly using JES. Rob is very knowledgeable and professional. Clearly, JES is a company with integrity.
