With over 40 years combined experience, we provide complete Basement remodeling and finishing services with Free estimates and no-nonsense pricing. We will give you the Basement you've always wanted by transforming your previously unfinished Basement into a usable and comfortable living area you can be proud of. We are known for constant communication and on-site project management.

"While our basement came out good, there were several extra costs that our PM John came up with that we feel could have been included prior to the work beginning in the contract or in the extras section of the contract. Things like stair replacement, trying to get us to install 2 sump pumps + a second electric panel. Regarding the pumps, the plumber actually recommended against the 2 pumps as he was able to connect all of our window wells to a single pump, also eliminating the need for a second panel. They also installed low quality hi-hats as our lights continue to flicker and pretty much told us that it?s normal and nothing can be done. Lastly, the workers left our unfinished area a mess at the end of the project- leftover debris and our furnace a water heater were left covered in dust. If you don?t mind feeling price gauged and having your concerns not taken seriously, this is the company for you. "

Basement Leak Repair questions, answered by experts

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

The frequency with which a French drain clogs depends on various factors, such as the amount of debris that enters the pipe, the quality of the French drain installation, the type of grate and filter used, and how often it is maintained. That’s why it’s recommended to clean your French drain at least once a year, whether it is clogged or not. This can prevent clogs and increase the lifespan of your drain.

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.

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.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
