"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.

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.

Foundation Repair questions, answered by experts

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Yes, thicker concrete is less likely to crack. The thicker the concrete is, the less susceptible it is to extreme changes in weather conditions that often cause concrete to crack or chip. If you’re unable to install a thicker concrete driveway for any reason, you can also ask your professional to install more rebar or wire mesh to provide greater strength and better resilience to damage.

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands. 

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.
