Crawl Space Repair

Crawl Space Repair in Fredericksburg, VA
Fredericksburg’s fluctuating humidity and clay-heavy soils make crawl spaces especially vulnerable to moisture damage. Left unchecked, this damp environment can lead to mold growth, sagging insulation, pest problems, and even structural decay beneath your floors.
At Kefficient, we provide targeted crawl space repair solutions built for the unique conditions in Fredericksburg homes. Whether you’re dealing with standing water after a summer storm or musty odors from long-term humidity, our team knows what to look for and how to fix it. From drainage and vapor barriers to full encapsulations and dehumidification, we’ll help protect your foundation and the air your family breathes.
Your home deserves a dry, stable base. We make sure it has one.
Foundation Repair

Homes in Fredericksburg are no strangers to shifting soil and seasonal moisture. These are two major causes of foundation problems. From stair-step cracks in basement walls to doors that stick or uneven floors, the signs of foundation settlement or lateral pressure can show up gradually, but their impact is serious.
At Kefficient, we specialize in diagnosing foundation issues early and delivering lasting repairs. Whether your home has a block foundation, poured concrete walls, or supports over a crawl space, our Fredericksburg team offers proven solutions like wall stabilization, crack sealing, and structural reinforcements tailored to your property’s needs.
We don’t believe in patchwork fixes. We believe in securing your home from the ground up, because peace of mind starts with a stable foundation.
Basement Waterproofing

Basement Waterproofing in Fredericksburg, VA
Whether you’re dealing with damp basement walls, musty odors, or visible water after a heavy Fredericksburg rain, moisture intrusion is more than an inconvenience; it’s a direct threat to your home’s structure and air quality.
Kefficient provides complete basement waterproofing solutions designed to eliminate existing problems and prevent future ones. Our services range from interior drainage systems and sump pump installations to moisture barriers and wall sealants, all tailored to the unique soil conditions and seasonal weather patterns in the Fredericksburg area.
By keeping your basement or crawl space dry year-round, we help protect against foundation damage, mold growth, and costly repairs down the line. Your home deserves to stay dry, safe, and strong, no matter what’s happening outside.
Mold Remediation

Mold Remediation in Fredericksburg, VA
Mold is more than an eyesore; it’s a health hazard that can quietly spread through your home’s walls, floors, and air systems. In Fredericksburg’s humid climate, particularly after heavy rains or basement leaks, mold can thrive if left unchecked.
Kefficient’s mold remediation experts use industry-leading tools and containment protocols to locate, eliminate, and prevent mold growth at the source. Whether it’s behind drywall in a finished basement or tucked away in an unsealed crawl space, we remove mold thoroughly and safely, restoring clean air and peace of mind.
Don’t trust temporary fixes or DIY sprays. Protect your family and your property with a long-term solution from Fredericksburg’s trusted mold specialists.

Attic Insulation in Fredericksburg, VA
A drafty attic doesn’t just affect your comfort. It also drives up your energy bills. In Fredericksburg, where summer heat and winter chill can put serious strain on your HVAC system, proper attic insulation is a smart investment in year-round comfort.
Kefficient’s insulation solutions are designed to seal in your home’s conditioned air while keeping pests and moisture out.

M u2025-12-11Trustindex verifies that the original source of the review is Google. They told me exactly what they were gonna do before they started then they finished the job. Show me some pictures and did an excellent job. They were very nice and professional. Charles Lunsford2025-12-10Trustindex verifies that the original source of the review is Google. Mack with Kefficient provided a detailed assessment of our crawl space with a number of pictures, I was impressed with the detailed contract agreement that was provided. The installation crew did a great job and cleaned up the work site each day. Kyle the project manager was very responsive in following up to phone calls and texts and visiting the site to follow-up on the work. I highly recommend Kefficient as a contractor for crawl space encapsulation. Erwin Camia2025-12-06Trustindex verifies that the original source of the review is Google. Thank you, Kefficient! Our crawlspace had mold, and the team did a great job taking care of it all. Brad was great and assisted us through the entire process, and was always highly responsive! The Kefficient work crew was able to get the entire job done, including installing a great new door, in just a day. We highly recommend Brad, and the Kefficient team! Cameron Trimmer2025-12-04Trustindex verifies that the original source of the review is Google. I am a Superintendent for a large commercial general contractor, and I fully realize that I am extremely picky, detailed and have high expectations for companies that I hire to work on my personal home. When I was researching different companies to perform my crawlspace encapsulation, I first heard of Kefficient through my co-workers that share the same expectations of high-quality work. During this process, I met with 3 companies to review and discuss the encapsulation process, and I must say that Kefficient stood out immediately among the others as being far superior and professional. Brad Conner at Kefficient came out to my home, walked me through the process, we discussed expectations and pricing. The price that Brad showed me, which was not inexpensive, was far more reasonable and the most honest number presented to me from all three companies. Other companies started with extremely high numbers then worked their way down, sometimes they'd cut as high as $15k off the number to try and beat the next guy. Could I have given the job to another company for cheaper? Absolutely. Did I give it to the most honest company with an extremely positive track record of quality, craftsmanship and professionalism? I absolutely did and that is what first won me over during my work with Kefficient. After about 2 months of permitting and an opening in Kefficient's schedule, Kefficient arrived on-site and began working. During the process I would go under my crawlspace each night after work to review their progress. Daryl, the crew foreman was also extremely professional and helpful by showing me through their process. During my visits, they had immense respect for my home, my yard, etc. by keeping it clean, organized and had minimal impact on my homelife. I would talk with Brad Conner every day, who by the way, was always available even if it was 9pm at night and I had a question or just wanted to go over the next day's plan to ease my anxiety of getting a project/home improvement of this size and cost completed to satisfaction. Brad Conner was so confident in his and his crew's ability to successfully complete my project and go above and beyond my expectations that he even had Mark Keffer, the owner of Kefficient, come to my home and personally inspect my crawlspace encapsulation and give it his stamp of approval before I paid the full amount for the project. Mark was extremely helpful in answering questions and it meant a lot to me that the owner of a company would be willing to meet me, look at my crawlspace and give his approval before I paid my final balance. I can't say enough good things about Kefficient and I am extremely happy with my newly encapsulated crawlspace. If it were just a bit taller, I'd have served Thanksgiving dinner down there it is so nicely done and clean! Elaine K2025-12-03Trustindex verifies that the original source of the review is Google. Brad met with us and provided estimate of work we needed done. The crew arrived exactly on time. Kyle was an amazing lead on this project. He was informative, professional and impeccable in terms of follow up. Definitely a great representation of the company. Nelson, Jorge and Roberto did a top notch job encapsulating our crawl space. Kyle walked (crawled) us through what they did. Very professional and great quality. We immediately noticed the difference in our home. Yes encapsulation does make a difference. What makes the biggest difference is getting a great company to do it! Kefficient is that company! Thank you Kyle and team! John Pascucci2025-12-03Trustindex verifies that the original source of the review is Google. I have been having Issues with my crawlspace for years. The previous company that worked on my crawlspace was terrible to say the least. I was referred to Kefficient. What a pleasant surprise. They arrived as scheduled, the employees are extremely professional and courteous, and they do great work. They keep their word, which seems to be quite rare these days. They have gone beyond Expectations straightened out my crawlspace. I highly recommend them. They’re just one of a very few companies that I can say this about. Drew Dickinson2025-12-03Trustindex verifies that the original source of the review is Google. We recently finalized an encapsulation project with Kefficient and can recommend them as a good company that takes care of its customers. The encapsulation looks great. We ran into a few minor issues, but Kyle, Jerrell, and Damion were responsive and made sure we were taken care of and that the issues were addressed promptly. We also had a Kefficient team (Klaly, Mia, and Katia) come out to do duct cleaning. They did a great job as well! Shout out to those staff in particular! Tony Som SR2025-12-02Trustindex verifies that the original source of the review is Google. We are very happy with our home crawl space full encapsulation job by Kefficient. Mike Andrews (Home Inspector/Consultant) arrived promptly for our appointment and explained the problem clearly and provided a detailed estimate to properly address the issues. Mike listened carefully to our needs, concerns, and preferences and provided expert guidance throughout the design of the work process. Mike and Kyle Shaw (Project Manager) kept us informed every step of the way and promptly addressed our questions or concerns. It was a pleasure to work with Mike, Kyle, and the work crew from the initial consultation through the completion of the project. They both also responded promptly to our texting and email questions and or concerns. The craftsmanship and attention to detail from the work crew, Andres, Ramiro, and Enel was second to none. The finished space is truly impressive. This work crew always went the extra mile to accommodate minor and extra request from me that were noticed as they were working. This work crew was just plain "Awesome". The finish product really exceeds our expectations, and we’re grateful to Mike, Kyle, Andres, Ramiro, and Enel for bringing our vision to life! Should you hire Kefficient for your crawl space work, I recommend you ask for this crew by name; you will not be disappointed. I would like to note that communication with the office personnel is very poor; they take forever to call or email back if they ever respond, Unfortunately, Do Not Waste Your Time! I learned quickly that is best to communicate with either your Home Inspector/Consultant and or your Field Project Manager if one is assigned; they both provided a great customer service. This is a 5 stars crew and Kudos for them! Money well invested. I highly recommend this crew.
