"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they “completed the job,” I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they’re saying that leveling the kitchen wasn’t included in the original scope, blaming the remaining dip on my kitchen island and fridge being “too heavy” and lacking proper support—an issue they failed to identify in the initial assessment. To properly address this problem, they’re now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I can’t help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that wasn’t there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as “standard” and providing terms within the contract absolving them—despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to “settle naturally”—a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you’re considering foundation work, I strongly recommend looking elsewhere—this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

Drain Pipe Installation questions, answered by experts

You need a sewage ejector pump if you have appliances or fixtures that use water below ground, such as basement sinks, bathrooms, or laundry facilities. If all of your indoor plumbing connections are above ground, on the main floor or higher, gravity can do the work without a sewage ejector pump.

An outdoor mixer tap lets you run hot water to an outside kitchen or greenhouse. Mixer taps do this by mixing both hot and cold water together for varying temperatures.

The plumbing industry has standardized the sizes for bathtub drains. They are 1 1/2 inches wide to fit all standard bathtubs from 14 to 26 inches deep. The standard sizing is to ensure that the drain fits into the P trap, a special part of your piping that prevents sewer water from bubbling up into your home (yuck).

How long it takes for a pipe to freeze depends on the outdoor temperature, the level of preventative measures taken, and how long the outdoor temperature stays below freezing. With this in mind, expect most pipes to freeze within six to eight hours. Uninsulated exterior pipes can freeze in under six hours if the temperature is below 20 degrees. It takes at least 12 hours for unprotected pipes to freeze at 32 degrees.

Depending on the issue, you have a good shot at fixing a leaking sink yourself. If you have some plumbing experience or are comfortable with DIY jobs, you can clean the P trap, tighten nuts, replace washers, and replace shut-off valve stems on your own. For more complicated jobs, such as repairing a garbage disposal, calling a pro may be the way to go.
