"Luis did an excellent job creating a laundry room for us. He converted part of our garage into an amazing room - you would never know it was once part of the garage as it flows seamlessly into the house. The herringbone tile floor installation was excellent, as well as the cabinets/doors/wall installation. Luis also had a team that managed plumbing, electrical, and hvac work.

Additional e-mail - info@better-built-basements.com. Award winning. The Mission of Better Built Basements, LLC is to have Connecticut homeowners select us as their remodeling contractor by providing innovative and affordable basement solutions. We strive to build trust and confidence with our customers with precise quotes, honest and consistent communication, professional appearance and demeanor, and accurate time lines for every project.

"Unfortunately I give BBB a 1 star rating. The project began October of 2021 with demolition, upon completion of each phase I sent an email to Better Built Basement management thanking them for their work effort and identifying items that either required further explanation and/or resolution. As the project went on, I became increasingly frustrated with their lack of communication, lack of accountability, lack of caring, and lack of skill. The straw that broke my back was when Jim (an owner) called me a f’ing c’sucker. Randy, (an owner) sent me the following email: No one has time to read your 3-page condensing e-mails. You have done nothing but complaint. It's obnoxious and draining to everyone you come in contact with. There isn't one person who cant wait to have you out of our lives. I terminated Better Built Basements on June 7th, 2022, here are some of the details of my experience: - The demo crew was excellent in and out in a day and did a great job cleaning up - The electricians were very consultative in their approach to the project, providing input on lighting and outlet placements. - Framing was mediocre. Despite using laser equipment, one wall was wavy and the ceiling grid has a large gap. Pictures attached. - New steel stud framing and pre-hung doors should be dead on straight as an arrow instead, two of the doors has an aesthetically noticeable skew. - The replacement to an existing door resulted in using the wrong hinge set for the existing mortices, inclusive of color – all the other hardware is brass they used chrome. Picture attached. - 3 of the four doors were either chipped or cracked. BBB was notified before the ‘final’ paint job, but they failed to address the issue. - I returned home the day they applied joint compound to find glops of joint compound on the floor, which I tracked around my house, and glops on wood work on a floor where no work was occurring. Pictures attached - Following the flooring installation, they left garbage in my basement for 2.5 weeks, then did not take it when they came back – in frustration I disposed of it myself. - Many of joints on the ¼ round trim molding were caulked excessively to cover up sloppy miters. - Cracked switchhplate was not replaced. Picture attached. - Sub-contractors have sub-contractors, who seem to be able to sub contract – direct employees of BBB other than the demo and electrical were rare. BBB demands using a lock box, Many people have the combination, providing little sense of security over access to the home. Overall, BBB does a bad job communicating, managing expectations and fails to deliver on their stated objectives at best they are contractors not craftsman."

Basement leak repair services FAQs

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.
