"ReThink completed our project amazingly. We had ReThink remodel half of our main floor. We turned an office and unused “front room” space into a perfect master suit. Our very unique home offered many challenges that the ReThink team was able to effectively work through and problem solve. They completed our project on time and within budget. The attention to detail exemplifies their professionalism and creates a beautiful product that they, and we, can be proud of. Their focus on customer satisfaction is evident in their performance and in their communication. We would definitely ask them to complete other projects!"

Each house gets our special brand of two guarantees 1( We commit to treat your house the way we would treat our own home giving the same pride of craftsmanship 2( We will do our best work every time. Yes! You will find it written into our contract. In every project there are only three essential elements schedule, cost, and quality.

Kellar Associates has changed the way residential construction gets done. We have formed relationships with subcontractors that share our beliefs of doing our best work every time and living inside of budgets.

We take a great interest in our customers to protect you from unforeseen circumstances when possible and to give information of unintended consequences when making your owners typical decisions such as finishes or changes.

Basement Waterproofing questions, answered by experts

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.
