"Title: Extremely Disappointed with Hallmark Stone's Countertop Installation Service ⭐️ Rating: 1/5 I recently had a countertop installation done by Hallmark Stone, and unfortunately, the entire experience was nothing short of a nightmare. From start to finish, it was evident that customer satisfaction was not their priority. First and foremost, the installation crew left an appalling mess behind. Chunks of the old countertop, dust, and debris were scattered all over my cabinets, creating a huge inconvenience and a considerable cleanup task for me. To make matters worse, they took crucial components required to hook back up our plumbing with them and never returned our calls when we inquired about it. We even sought assistance from Home Depot, but they too failed to elicit a response from Hallmark Stone for three long days. Dealing with them prior to the installation was no better. Their communication was incredibly terse, and they seemed disinterested in addressing our concerns or questions. The lack of customer focus was evident, leaving us feeling ignored and undervalued. The most alarming part of this entire ordeal was discovering dangerous tools left in our cabinets. Among them was a cutter similar to a razor blade. What if a child had found it before we did? This level of negligence is unacceptable and puts people's safety at risk and on top of that I still have no working plumbing. I highly advise potential customers to think twice before considering Hallmark Stone for any service. They have shown a complete lack of professionalism, safety awareness, and basic customer care. I would strongly suggest exploring other options for your countertop needs to avoid the frustration and potential hazards we encountered."

FAQs for basement remodel projects in Alton, IL
Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:
Replacing insulation
Replacing carpet or other flooring
Adding heating and cooling
Adjusting or adding walls and doors
Altering or adding plumbing elements
If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:
Painting walls yourself versus including in the cost of the remodel
Installing light fixtures yourself
Choosing prefabricated fixtures, like cabinets, over custom ones
Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
