"The job inside was done. However the drainage put in outside has turned our yard into a swimming pool. We once had a pipe draining to the creek and this was a perfect solution to the rains/weather. These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

Basement Leak Repair questions, answered by experts

You may have to dig out drain valves if they are buried under dirt. This method isn’t ideal, and it increases the chance of clogs and damage. Ideally, a drip irrigation system buries drain valves in a gravel pocket so they are easier to access and better-protected. If you have trouble accessing drain valves, hire a sprinkler professional to find them safely and efficiently.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

The need for permits in drainage improvement projects depends on your location and the extent of the project. Generally, projects involving significant excavation, alterations to existing drainage systems, or those impacting public drainage systems may require permits. Check with your local building department or authorities to determine the specific permit requirements in your area before starting any drainage improvement work to ensure compliance with local regulations.

A burst pipe can cause hundreds or even thousands of dollars in damage. It could flood your home, which can destroy many of your belongings. It could also ruin hardwood floors and carpeting, requiring you to replace your flooring. Finally, mold and mildew form very quickly after high levels of moisture have been introduced to a space; this is not only costly to remove but also bad for your health.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly
