"Signed contract on May 8 for deck build.On May 12 rep came to my office to collect deposit of apprx $13,000. He said project team meeting on Wed & would update me then on start date etc. On Fri May 16 I had to reach out to him. He wrote the team had met & materials were ordered. An hour later he wrote back that he was misinformed & that his boss was going to call me next week. Despite this, dep check cashed. On Mon 5. 20 rep wrote back that they had forgotten certain costs & to proceed it would be $8,000 more. Not a typo. $8,000 more. No apology. Ridiculous, contract rescinded. I wrote that he could return my deposit at my office just as he had collected it. On Wednesday the 21st I got a text from "Tom," presumably the owner/boss, saying he would "drop a check in the mail" to my address. Today is May 30th, Friday, and still no check. Check at a minimum should have been overnighted. They owe me interest not to mention the deposit to hire a contractor who will honor contract. Bad."

I am a small construction company with myself and three other employee's, I do all aspects of the jobs. except, Plumbing, Electrical, Excavation, and H.V.A.C., and Plastering, which I provide the contractors for. Billing procedures, usually are 1/3 at the start, 1/3 mid point and final payment upon completion of the project. I am fully licensed and insured.

"We’ve worked with 3G’s a few times now and they, once again, did not disappoint. The team repaired a bedroom that had been damaged, installed a new front door, and updated our siding and window frames, and they did an outstanding job. Their workmanship was excellent, and everything turned out even better than we expected. The crew was professional, friendly, and easy to work with—great communication, always on time, and very respectful of our home. The entire process was smooth from start to finish. We couldn’t be happier with the results and would absolutely recommend them to anyone looking for quality work and a great experience."

Basement Remodel questions, answered by experts

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

It costs an average of $32,000 to finish a basement, and most projects total between $15,000 and $75,000. If you just want to make the space look a bit nicer and don’t need to convert the basement to legal living space, you could spend as little as $3,000 to install drywall and flooring. On the other end of the spectrum, your costs could rise to $100,000 if you want to make structural changes to the space, repair existing structural damage, waterproof your basement, or install a kitchen and bathroom along with living space.

Generally, a wall can bow up to 30% of its thickness, or around 2.5 inches for an 8-inch-thick structure, before it becomes an urgent situation. If your basement wall bows more than 1 inch, it's time to have a basement inspection to determine if a repair is necessary, depending on the soil conditions and structural specifics. Walls nearing 4 inches of bowing will require significant repairs. More than 6 inches of bowing usually means the wall will need replacing.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
