"RUN FAR AWAY FROM ALLIED AND TOM. Tom took my money and did not complete the renovations as per our contract. He lied about having a licensed electrician to do electrical work, it was just one of his workers who's not licensed. I paid for a dumpster and when it was delivered by tom it was already half full from another allied job and I was asked to pay the full amount of $950. Tom didn't listen to anything I said regarding the work I requested and he changed my design and did work that was cheaper for him. I was priced for one of my ceiling's to be ripped out and reinstalled with new sheetrock, Tom waited until I was away on business then he installed sheetrock on top of the bad sheetrock and told me he ripped out the old sheetrock and installed the new sheetrock, I found out when my EC cut holes to install lights and we found 2 layers of sheetrock preventing the lights from being able to be installed. Allied construction is a cheap, sneaky company who will steal your money and breach your contract. Do not hire these people Tom is a lair. Tom wore a gun in my house on his hip and told me "I use this to get paid by customer who don't want to pay". Tom left live 120v wires hanging out of the walls and ceiling, he removed a banister and didn't replace it for 3 weeks making my home very unsafe for me and my 9 year old son."

FAQs for basement leak repair projects in North Massapequa, NY

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.
