"Honestly, I have never had such a positive experience with a contractor. they showed up on time, were friendly, polite, courteous, clean and efficient. In a single day they installed the entire system and left the place clean (within reason). This included jack hammering more than 30 feet of concrete floor and complete water ejection. Unbelievable. They will never be the cheap solution, but they are worth it!"

"Both my wife and I are extremely happy with the work that Arnold, his dad, and his helper did to remove the old wall, prepare a foundation, and install a new colonial fieldstone wall. Plus, I got to keep the old stones for my own various projects! ARNOLD’S MASONRY & CONSTRUCTION LLC is an “old world” craftsmanship company who cares about the quality of the work & the details. It really shows in their final product! I would very highly recommend them for any projects!"

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

"Again! I call on Perez Asphalt and paving. And again they did a great job! They also did my driveway. Prompt, Efficient, they were neat. They were focused on the task at hand. They showed up they did the job with patients, cleaned up and left. The best part was the fair price, someone else tried to charge me more than double for the same job. Good experience throughout!"

"The reason I first hire them is to look at the boiler to reconnect the pipe so I can get it tested. The plumber came and he told me he does not do that work. They lock you in with the deposit and so you use it or loose it. The work that was done was okay. To reconnect two 1.5" drain pipes for $450.00 is a lot of crap. I would not hire anyone that would ask for a deposit, for it is the games that they play. Use it and they still charge you more for the job."

"John and his team did a great job. We contacted them to fix concrete steps in our back yard leading to our deck and he was able to provide all options for replacement, costing and timing. He was very respectful of when we wanted to get the project done and I felt like he knew exactly what needed to be done. I would highly recommend John and his team to anybody who needs masonry work."

Foundation Drain Installation FAQs, answered by experts

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

Yes, most contractors and installers offer warranties covering materials, parts, labor, and workmanship for their installation services. It is important to confirm the specific terms and coverage details with your provider before starting the project.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

The type of stormwater drainage system you need depends on your area’s storm severity and frequency. Your property’s location should also be considered, including the surrounding soil type, nearest roads, existing drainage systems, and slopes and hills. Your property’s structure, such as decks, walkways, crawl spaces, and foundation, also affects what drainage system will work the best.

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.
