"The work was fine, at least so far! We hired them to repair cracks in the foundation, and the estimator thought that there were three cracks. When the person showed up to do the work, he only found (and repaired) two cracks. It took several months for them to adjust their bill, which is my only complaint. It took several phone calls and emails, and they didn't reduce the bill very much."

Customers say: Quick response

"Contacted Mike after waiting for the original plumber we called to cal back (never heard from him) . My daughter told us about My Guy had plumbed their bathroom. Mike told us he would be in Spokane on the 10th of March and that he could do a laundry room sink install in the afternoon. We sent him pictures of the old sink and the plumbing set up. He arrived as promised with all material in hand and within 4 hours he and his apprentice completed the job. The completed project was far better than we had ever hoped for. They did a total cleanup and removed the old concrete sink and did it all at a reasonable price. We would not hesitate to recommend Mike for any plumbing job."

"We had a complicated job to widen a basement walkout, which included demolition of walls and steps that had been improperly installed. We also wanted other steps and a patio demolished and new steps and patio poured, as well as sidewalks. We got bids from several contractors who were willing to do the job but seemed not to necessarily know what they were doing. Chris Ferraro gave us a bid, and we knew right away that he knew what he was doing and would do a quality job. It wasn't cheap, but it was well worth it to have the work done right and look great."

Foundation Drain Installation FAQs, answered by experts

A range of certified professionals can install French drains, from foundation specialists to plumbers. However, you’ll want to make sure that the professional has a breadth of experience installing the specific type of drain you need in or outside your home. Your contractor should also have experience with sump pumps, waterproofing, and flood-proof landscaping.

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.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

The cost to install a new sump pump, including materials and professional labor, typically ranges from $1,000 to $3,000. The average cost is often cited between $1,200 and $2,500. Several factors influence the final price, including the type of pump, the complexity of the drainage system, and the installation location. For instance, installing a sump pump in a basement may cost around $1,200, while a more complex installation in a crawl space can cost an average of $3,900. It is important to hire a licensed professional for the installation to ensure quality work, which can impact the pump's lifespan and warranty. Note that these costs are for a new installation; replacing an existing unit is less expensive, typically costing $308 to $748.

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.
