"I hired this company to design my backyard landscape and they did a fantastic job. The designer was creative and came up with a beautiful plan that incorporated all of my ideas. The installation process was seamless and the team was professional and efficient. I now have a backyard that I can be proud of and enjoy all year round. I highly recommend this company for anyone looking to enhance their outdoor space."

"I highly recommend Groundworks for foundation concerns. They were very prompt with returning my call and providing a free inspection. I had concerns for my 103 year old home, especially a section of the foundation. Their Inspector, Bob Bloom, arrived on time, was professional and experienced, took time to answer all my questions (thank you for not rushing), and provided me with useful feedback on my foundation and options for repair. Bob gave an honest assessment with no sales pressure. Although I decided to defer foundation work at this time, I will definitely use them in the future."

Your plumbing problem becomes our problem to solve.\n\nThat’s not just a tagline, it’s how we operate. When you call GOFLOW, you’re getting a team that knows this area, knows plumbing, and genuinely cares about doing the job right.\n\nWe’re not a franchise. We’re not a call center routing you to whoever’s available. We’re a local company built by plumbers who got tired of watching customers get treated like transactions instead of people.

"Joseph was on the job when he said he would be here. He is knowledgeable about the issue I presented, but did not try to oversell me on the job. He did notice that an electrical outlet could be improved with not a lot of time or money and which made my system safer. I would definitely hire Joseph and DIvine Electric again when I need them.

"We re-did our driveway, front paths, side yard & backyard, making an entirely new look. eLite did a good job of making adjustments & gave expert advice. We even did a rather unusual path: we made a bridge over a dry creek bed. The entire project was completed in record time, with a very experienced crew. We're happy with the outcome & highly recommend."

Foundation Drain Installation FAQs, answered by experts

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

Heavy rain can affect a leach field because the extra rain can cause the groundwater level to rise. This leads the soil around the leach field to become saturated with rainwater, so it’s no longer able to take in effluent from the leach lines for final treatment. Heavy rainfall can cause the leach field to flood.

No, homeowners insurance policies do not typically cover sump pump installation. However, some companies may offer incentives in the form of discounts or reduced premiums if homeowners install sump pumps. Insurance companies do this because sump pumps can reduce water damage claims. You may also be able to obtain enhanced water-backup coverage after installing a sump pump.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

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.
