"My husband and I are in our 70’s. All of the upgrades/construction in our house in over 26 years was done by my career-construction husband. But recently he hurt his back. We needed our guest bath prefab bathtub/shower removed and replaced with a NICE prefab WALK-IN shower handicapped out. Our 95-year old mom was coming for a 2-week visit. We only had 3 weeks notice. Ani Kevorkian, owner of LGC Construction came to our house 1 day after I called. She listened, REALLY listened to what we wanted and understood the time constraint. She gave us a quote within hours and started the job within days. Her two gentlemen who came out were just awesome and cleaned everything up each day. Then Ani surprised us with “barn-door” glass shower doors that we didn’t even know we were getting. The shower is just beautiful! This company is exceptional. I have and will continue to tell our neighbors, people at our church, friends, etc. about LGC Construction! You can TRUST THEM!!!!"

"Cornelio was great. He did a marvelous job refinishing our bathtub, which was in poor condition. LA Reglazing's price was reasonable, and its service was prompt. Weeks later, we discovered a small bump in the reglazing. I contacted Cornelio, who came out the next day and fixed it at no charge."

FAQs for basement leak repair projects in Alta Loma, CA

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.

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.

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.

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.
