"Our house is almost 130 years old, so we needed to have some foundation stabilization done. The company was a pleasure to do business with. From our initial consultation and beyond, every contact was courteous and knowledgeable. On the first day of the project, after removing the dirt to see the foundation, it was discovered that the existing foundation was not sufficient to support using the helical piers according to the building inspector. The dirt was all replaced and it was arranged to come back out and give me a quote for a different process using smart jacks. Due to circumstances at my local building department, the new job had to be postponed until a new permit could be obtained. Once that was done I was rescheduled and the job was completed in a day and a half. When the building inspector came to sign off on the permit, he raved at what a great job they had done. I would definitely recommend them to anyone who asked."

"Mason and Dillon were absolutely wonderful to work with. They were both very wonderful and knowledgeable. They took the time to help us fully understand all the processes for both dealing with insurance and coordinating with the plumbers. They made a very stressful time so much easier and very very appreciative. 5 stars for sure!"

"They came out as scheduled and were able to complete the fence in about 3 days. It included setting posts in concrete and constructing the panels on site as well as two gates, one wider gate in line with outside gate for wheelbarrow entrance and the other narrower and on side close to sidewalk. They also installed wood boards under fence so critters including my dog are discouraged from digging under. Gates have nice latches including a wire loop on the inside to pull the latch open when exiting. I was very pleased with the result. They were respectful of the existing plants and raised bed rows taking care not to trample more than necessary."

Foundation Drain Installation FAQs, answered by experts

Installation typically takes 1-2 days, depending on the scope and site preparation.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

A grinder pump is a major investment for homeowners and business owners alike. Protect this investment by choosing a reliable and reputable contractor to source the pump itself, install it, and outsource any additional work. Research local sewage system contractors ahead of time to ensure they have the appropriate insurance and licensing. You should also perform a fairly thorough online search to get a feel for the company’s professionalism by reading reviews.

Finally, give them a call to discuss the project. A good technician will be more than happy to get into specifics regarding both the installation process and the pricing.
