"Very professional. Completed the job in two weeks. The deliverables were as promised. They were very independent, requiring only minimal involvement from the client. However, communication with the owner could be enhanced a bit."

"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!"

"Drew from Legacy Plumbing came out IMMEDIATELY to our rescue because not only were all toilets and showers unusable because water would flood downstairs but we had a birthday get-together with family happening within the hour. Drew was very knowledgeable and quickly fixed our clog and we needed a replacement part for an obvious leak. Legacy Plumbing is super honest, and you don't feel like you're getting ripped off with unnecessary b.s.. This is the second time we've called and because of the great job he did on our last major issue with our old pipes, we called him again. The cleanliness, effeciency, and honesty of this company is why I felt compelled to rave about them and let people know in a review. Definitely my plumber and business to recommend from here on out."

"So far, I've been really happy with them. It's one of those things where time will have to tell if it solved the problem. They were good. They did everything they said they're going to do. I would recommend them. This one charged significantly less for the same job. They charged $2000 for the same job the other company would charge $3000. They're better on pricing and they're fully professional."

"I had to reschedule our original appointment date. Omar was understanding and we rescheduled to another day that fit my work schedule. Omar and his son arrived on time and ready to work. We did a tour of all the varied work I wanted done. We began in the garage because I wanted to direct how I wanted the garage organized. We worked well together. Omar made some good suggestions and listened to what I preferred as well.
In the house Omar had all the tools to check out lights in both bathrooms and toilet. He had the equipment in his truck for master bathroom lights and toilet. He needed to replace the light ballast in guest bath which required him going to a couple of hardware stores to find the right fixture. While Omar worked on lights and toilet, his son and I worked on assembling the curio cabinet and mirror.
Overall it was a very good experience and I will continue to use Omar to help around my home.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
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.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
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.
