Down Under Waterproofing & Foundation RepairAs stated above, the solution and the work were done very professionally. Haven't had water in the basement since.1900
Went great !! Charles showed up prompt and the same day I called. Very honest man, and didn't sell me things that I didn't need. Professional and polite, walked me through the entire basement and educated me on basement leaks and remedies
I live in a flood zone and despite repeated heavy rains and some flooding in the neighborhood, my basement remained dry enough that it is now a living space. I had some issues pertaining to the basement bathroom - namely, the sink wasn?t reinstalled when they put in the drainage system....
Basements Love Us IncSo far the leaks have stopped. I would definitely use Dwayne Mainardi for roof replacement or repair work again.
Duane Mainardi Builders LLCThe inspection went well. The inspector caught alot of issues with the house. One of the issues was high levels of radon gas in the basement level. Another issue was a gas leak from the pipping to the furnace. We smelled the gas odor as soon as we entered the basement. The inspector...
This is for a rental property I own. I contacted PlumMedic and described the issue. I told them my tenant would call to arrange for them to come out. They repaired the leak and then called me the next day for my credit card for payment. I did not want to have my tenant pay.
Plumb Medic Inc.We were very pleased with the work. Jim is professional, does excellent work quickly, and is very price conscious. He and his helper were onsite each day and were pleasant to work with. They work neatly and clean up. He is upfront about what the project will involve and costs for various...

Being in the architecture business for the past 34 years we have the experience and knowledge of building design to offer our clients quality services for their projects.
"We were in the process of renovating our apartment and needed to apply for permits from the government, which required an architect-signed design drawing. Anthony came highly recommended. He took the time to visit our apartment and carefully understand the challenges we faced in obtaining the permits. After thoroughly reviewing the space and listening to our renovation ideas, he assured us that the project would be straightforward for him and that he could provide an architectural drawing that would not only meet our needs but also ensure we could pass inspection without any issues. Despite the project being relatively small, Anthony was more than willing to take it on and offered a very reasonable fee for his services. We truly appreciate the time, care, and professionalism he brought to the table. We would highly recommend Anthony to anyone looking for an architect who is knowledgeable, approachable, and dedicated to delivering great work."

"Davidson and Son. I had a deck around my pool put up exactly 1 year ago from today by Justin’s and his crew and it is now separating from every joint and he refuses to fix it. He told me he would be back last year because the wood started to warp after a month of being up and he never came. I let it go because it was only a couple pieces but now the entire deck is separating. There are a ton of nails and screws the deck posts were pit directly into the ground instead of using sona tubes so it will surely rot a lot quicker if it was done the right way. Mind you this is someone I have known for years as well and does not stand behind his work and told me he spent enough time on it and will not fix it and doesn’t make the wood. Except if everything was plum etc. it wouldn’t be doing this."

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.
