"From the first visit to my home from Sean for an estimate, to the crew that arrived to do the project I was impressed. Everyone was extremely professional. The crew arrived on time, the crew leader introduced me to the rest of the crew and explained how they would proceed with the project. They protected the work spaces with plastic from my garage to the crawl space opening in side my closet. They went to work and kept me informed about the progress. The whole crew worked very efficiently and got the project done in one day. They left work area spotless when they were done. I would highly recommend this company for any waterproofing project!!"

"Dylan Milroy went in and cleaned out the crawlspace put down plastic and dug a french drain and redirected all the downspouts so that the rain and we had now more water being drained. He is super easy to work honest he follows up to see if you are satisfied with his work.. I recommend him to everyone."

"Friends who know what our basement looked like before are flabbergasted. The information they send you after you contact them is super educational and everyone was prompt, polite, and professional. Wish we'd done this sooner."

"The problem ended up being plumbing and not waterproofing. But TerraFirma did a consult right away, diagnosed the issue quickly and was really helpful in figuring out the next steps. I really appreciate their time."

"Well, it's fixed. A learning experience ? get many bids and make sure the company wants your business. Pros ? Technicians were polite and respectful of my home while I worked in meetings all day. ? The pooling water issue in the basement was resolved, and the floor is now dry; the work was ultimately completed. ? Initial estimate visit was free, but not thorough ? Senior staff came out later to apologize and review the work. Cons ? Pricing was far higher than industry norms based on later bids. ? Avoidable scope changes and price increases after work began; two other plumbers said the job could have been done as originally quoted. ? Communication issues (delayed quotes, unclear explanations, forgotten site details). ? Work quality/finishing didn?t match the premium price; two professionals asked if we had done the work ourselves. Added pictures because I don't know plumbing, so you decide if you'd want this. ? Extra fees add up: 10% financing fee (Synchrony) and 4% credit card fee."

"Excellent experience. Compared to all the other plumbers who came out an gave an estimate I could tell that Henco new what they were doing and showed confidence. Loren was an excellent problem solver and was able to accomodate my request to move the whole soil stack 5 feet to an exterior wall. Very happy with the work. An additional nicety was they had a "build back" guy (Chad) they had available to restore surfaces and paint. Very convenient. Finally, all projects have hiccups... mishaps can happen but I am glad to say Owen was very fair and reasonable to deal with. Overall I highly recommend Henco. I have already recommended them to multiple neighborhood friends. Everyday I use the plumbing I smile."

Basement Waterproofing questions, answered by experts

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
