"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"I bought the Big Deal which was just for a single top coat to reseal the deck surface.  However, my deck was in a little bit worse shape than the deal allowed.  However, Ryan was awesome and added in sanding and then did the reseal for no additional charge.  The surface is not perfect but that is due to the rough pre-condition it was in and not his fault.  Shortly after the reseal the deck drains started leaking in to the garage below.  Ryan and crew came out again to fix the drain at no additional cost.  Again, this was not in the deal I bought but they provide such great customer service.  I would definitely use them again and will recommend them to friends and neighbors!

"Jake and his team were terrific to work with! From careful diagnosis of our problem, troubleshooting possible causes and solutions, providing options and doing prompt and careful work - Your City Rooter & Plumbing was great, and I will for sure use them again. They take pride in their work, explain their progress as they go and left the job site as tidy as it was when they arrived. Thanks Jake!"

"My house was in shambles and required a full makeover. We also wanted to add a shower to the downstairs bathroom for my mom as she gets older and stairs are getting tougher. I got 6 estimates and most came back much higher than the one I received from US Home developers and their definitions of work to be provided was also very vague, and left a lot of room for additional fees. Belle gave me a very detailed contract outlining everything that would be done. Armando was our contractor and like Belle, he was an absolute pleasure to work with. The work was done very quickly and only took as long as it did because of wait times for material. Belle met with us a few times to shop for material and helped us through the design process which was very helpful because I was stressing out on this aspect. Armando made sure everything was the way I wanted it to be and was very flexible when it came to scheduling. At the end of job he even had all the junk in my backyard, which was a lot, picked up. I was so happy with the work they did downstairs that I decided to rehire them to do the upstairs. They even added roof replacement to the contract for an additional price that was much lower than the 4 other estimates I got. My house went from looking like it was straight out of an episode of Hoarders to looking like it’s straight out of a magazine. Couldn’t be happier!"

Basement Waterproofing FAQs, answered by experts

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
