"I hired Tony to replace my roof which included a new attic fan and new gutters. He also replaced a very large bay window for me. I cannot say enough good things about him. The price was fair, the workmanship excellent and all his staff professional and courteous. I asked Tony about another window and he suggested I might be able to find someone to repair it rather than paying to replace it. You can’t ask for a more honest businessman! Five stars all around. I highly recommend him!"

"Contacted National Home Improvements regarding leaking patio roof and no follow up response to issue since last year of April 2023. Still awaiting to hear back. Seems like the rain gutter is sagging in the middle of the patio where the two joints meet and water is pooling there and possibly leaking through the seams as illustrated in the photo. Poor design concept. Really disappointed with customer service and quality of product especially for what we have paid for. They clearly don't care about taking care of their customers. I would never hire National Home Improvements again!!!"

Basement remodels FAQs
Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:
Replacing insulation
Replacing carpet or other flooring
Adding heating and cooling
Adjusting or adding walls and doors
Altering or adding plumbing elements
If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.
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.
Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:
Painting walls yourself versus including in the cost of the remodel
Installing light fixtures yourself
Choosing prefabricated fixtures, like cabinets, over custom ones
Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary
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.
