What a great experience working with Crawl Space Doctor, LLC. Rich and Kerry did a great job encapsulating our crawl space. We asked them if they would recommend someone to make our driveway look great again. I tell you what. They are not just Crawl Space Doctors, they are also DriveWay Doctors. Took them one day to make our driveway look great and add spot for the boat trailer parking.Thank you for such a great work for very reasonable price in very timely manner. Before you make your final choice - give them a call. Kerry and Rich hands on 100%. Owners and Operators! They give you estimate and get your job done! Highly recomend.

I received several quotations to encapsulate my crawlspace on my 35-year-old home. Crawl Space Doctor was the first to arrive and provided for me nearly an immediate quotation that was very thorough and competitive. That was not what impressed me the most. Not only did they provide a service that they contracted but they went beyond and above and they fixed other things that were needed underneath my house at no extra cost. They kept me informed of the progress and followed up afterwards to be sure everything was perfect. And it was.

We glad we found them! Richard and Carry definitely know their stuff! After getting two estimates from big corporate companies DryZone and CrawlSpaceNinja we decided to go with smaller local company. Same quality materials and installation but you pay half price! Everything was done in timely manner. No hidden charges. Any extra work at fair price. They are not going to sell you what you don't need, but if something needed attention they will point it to you. We are very happy with crawl Space Doctor, LLC and already recommended to our friends and neighbors. Before you make your final decision - call this Guys. It dose not cost any more to go first class! Money you safe with them- use for your next home improvement project

Crawl Space Doctor was fantastic. They were reliable, professional, and courteous. Richard walked me through the entire process and was there for me after installation to answer any questions. Crawl Space Doctor takes pride in their work and it shows. I highly recommend.

Crawl Space Encapsulation

We seal your crawl space with a high-performance vapor barrier, preventing moisture buildup, mold growth, and structural damage. Encapsulation improves indoor air quality and reduces energy costs.

Crawl Space Repairs

From wood rot to sagging floors, we reinforce and repair your crawl space structure to protect your home’s foundation and prevent costly future repairs.

Vapor Barrier Installation

A properly installed vapor barrier blocks ground moisture, keeping humidity levels low and reducing the risk of mold, mildew, and pest infestations.

Dehumidifier Installation

We install energy-efficient dehumidifiers designed to regulate humidity, improve air quality, and prevent condensation-related issues.

Crawl Space Cleanup

We remove unwanted materials, rake and level the area, and leave your crawl space clean and organized, restoring it to a safe and healthy condition.

Commercial Crawl Space Services

We offer custom moisture and foundation protection solutions for businesses, ensuring commercial properties stay structurally sound and energy-efficient.

Subfloor Repair

Years of trapped moisture in your crawl space can weaken the decking beneath your floors, making it unsafe to walk on. When it comes to our subfloor repair service, we cut out the damaged panels and rebuild a sturdy base that supports your finished flooring as it should.

Metal support posts and pipes beneath a wooden floor, with a dehumidifier unit on a plastic-covered ground in a crawl space—ideal conditions for effective joist repair and sagging floor repair.

Joist Repair and Sagging Floor Repair

Bowing framing beneath the house slowly pulls your rooms out of level. Our joist repair and sagging floor repair sets DynamicPost jacks and steel I-beams under the load, then replaces any joists too far gone to save.

Crawl Space Doors

The entry to your crawl space is often the last thing sealed and the first thing to fail. Our crawl space doors replace flimsy, rotted panels with insulated, tight-fitting units that lock out humidity and pests.
