"Everything about this repair job was wonderful - from Brad giving us the bid (and explaining exactly what would be done), to Will and Ree (sp?) doing the excellent work. Everyone was courteous, professional and left everything spotless. And the cost was surprisingly lower than I thought it would be."

"Andrew did a fantastic job. He was very knowledgeable and explained the pros and cons of the different waterproofing methods he recommended I apply to my basement foundation to make sure it stayed sealed long term. He was very professional, a good communicator, cleaned up after himself, and made sure to provide updates throughout the work. He even repaired a cracked portion of my sewer while installing a sump pump. Would highly recommend! Not a lot of waterproofing companies out there like Affordable that are a one man show, which is the best part. One man job = one way communication and responsibility. It hurts me not to give him a full 5 stars, but the only minor con I can bring up was how the work was some charges tacked on at the close of the project, due to some extra cost he told me he incurred for the pipe/connections needed to repair/replace the cracked pipe. The labor materials for repairing the damaged pipe were listed on the original firm bid I received before the project started. As I said this was a VERY MINOR con and I feel you will not find a better contractor out there to replace Andrew for your waterproofing needs!"

"I saw them in the neighborhood, so I got their details and they gave me an estimate. They were re-repairing a crack from 20 years ago. They did their work and cleaned up afterward. I waited until after 3 or 4 serious rain storms before this comment. The basement still dry. No seepage through the cracks. I should have called them a long time ago."

"The technician that did the service, let me know specifically one thing that turned not to be possible. I would never known, because the issue was below the ground. He also gave me post sales advice to recommend to my A/C who would be installing a unit near the repair."

Basement Waterproofing questions, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.
